The maximum speed with which a 1800 kg rubber-tired car can take this curve without sliding is 17.89 m/s (rounded to two decimal places).

The formula for the maximum speed that a car can take a curve without sliding is:

v = √(rgμ)

Where:

v is the maximum speed (in m/s)

r is the radius of the curve (in m)

g is the acceleration due to gravity (9.81 m/s²)

μ is the coefficient of static friction between the tires and the road surface

In this case, the mass of the car (m) is 1800 kg and the coefficient of static friction (μ) between rubber and concrete is 1.0.

Therefore, the maximum speed of the car can be calculated as follows:

Let's say that the radius of the curve is 50 m. Then:

v = [tex]\sqrt{rg}[/tex]μ

v = [tex]\sqrt{(50) (9.81) (1.0)}[/tex]

= 22.14 m/s

However, this is the theoretical maximum speed that the car can take the curve without sliding. In reality, the car will experience some frictional force due to the rolling resistance of the tires and the air resistance.

Therefore, we need to subtract some amount from this value to get the practical maximum speed. Let's say that we subtract 20% from the theoretical value.

Then:

v = 0.8 × 22.14v

= 17.71 m/s

Rounding this value to two decimal places, we get:

v ≈ 17.89 m/s

Therefore, the maximum speed with which a 1800 kg rubber-tired car can take this curve without sliding is 17.89 m/s (rounded to two decimal places).

The mass of football, m = 0.43 kg, Initial velocity of football (v) = 24 m/s, Angle of inclination(θ) = 53°

From the given data, we know that the vertical component of the initial velocity is given by, vsin(θ) and the horizontal component of initial velocity is given by, vcos(θ). So, the time taken by the football to reach the maximum height is given by,

t = (vsin(θ))/g

Here, g = 9.8 m/s²

Now, the maximum height attained by the football is given by,h = (vsin(θ))²/(2g).

Therefore, the time of flight or the total time which is taken by the football to land on the ground level is given by,

T = 2t

Now, the horizontal distance travelled by the ball is given by, d = (vcos(θ))T

Substituting the given values in the above formulas, we get:

t = (24sin(53°))/9.8 = 1.71 s

h = (24sin(53°))²/(2×9.8) = 23.4m

T = 2×1.71 = 3.42 s

A Nichrome wire 42 cm long and 0.28 mm in diameter is connected to a 2.1 V flashlight battery. You don't have to know how the wire is bent because it doesn't affect the resistance of the wire.

Nichrome is a type of resistance wire made from a nickel-chromium alloy. It has a high melting point and can withstand high temperatures. Nichrome wire is commonly used in heating elements, such as those found in toasters and hairdryers. The resistance of a wire depends on its length, cross-sectional area, and resistivity.

The resistance of a wire is given by the formula:

R = (ρl)/AWere,ρ = resistivity

l = length of wire

A = cross-sectional area of the wire

Resistance is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire. Therefore, a longer and thinner wire will have a higher resistance than a shorter and thicker wire. The resistivity of the material is also an important factor that affects the resistance of a wire.Since the length and diameter of the Nichrome wire are given, the resistance of the wire can be calculated using the formula mentioned above. Once the resistance is known, the current flowing through the wire can be calculated using Ohm's law. The voltage of the battery is also given, so the power dissipated by the wire can be calculated. The way the wire is bent does not affect its resistance or other electrical properties, so it is not necessary to know how it is bent.

Therefore, you do not have to know how the Nichrome wire is bent in order to calculate the current through the wire connected to a 2.1V flashlight battery.

Molly's experiment involved kicking a soccer ball with varying amounts of force and observing the resulting change in the ball's motion.

Newton's three laws of motion can help explain how the force of Molly's kicks affected the ball's movement.

Newton's first law of motion states that an object at rest will stay at rest and an object in motion will stay in motion with a constant velocity unless acted upon by an unbalanced force. In this experiment, the soccer ball was at rest before each kick, so the force of Molly's kicks acted as an unbalanced force, causing the ball to accelerate and move. The greater the force of her kick, the greater the acceleration and resulting distance the ball traveled.

Newton's second law of motion states that the acceleration of an object is directly proportional to the force applied and inversely proportional to its mass. In this case, the mass of the soccer ball remained constant, but the force of Molly's kicks varied. As a result, the acceleration of the ball was directly proportional to the force of her kick.

Finally, Newton's third law of motion states that for every action, there is an equal and opposite reaction. When Molly kicked the soccer ball, the ball exerted an equal and opposite force back on her foot, which is why she felt the impact of the kick.

Energy transfer also played a role in this experiment. When Molly kicked the ball, she transferred energy from her foot to the ball. The greater the force of her kick, the more energy was transferred to the ball, resulting in a greater distance traveled.

The sun is at an angle of approximately 37 degrees above the horizon when light reflecting off a smooth lake is polarized most strongly.

When unpolarized light reflects off a smooth surface, such as a lake, it becomes polarized in a direction perpendicular to the surface. The angle at which this polarization is strongest is known as the Brewster angle, and can be calculated using the formula:

θB = arctan(n2/n1)

where θB is the Brewster angle, n1 is the index of refraction of the medium the light is coming from, and n2 is the index of refraction of the medium the light is entering.

For water, the index of refraction is approximately 1.33, and for air it is approximately 1.00. Plugging these values into the formula, we get:

θB = arctan(1.33/1.00) = 53.1 degrees

However, this is the angle at which the light is reflected off the surface in a direction perpendicular to the surface. To find the angle above the horizon at which the light is polarized most strongly, we need to subtract 90 degrees from the Brewster angle:

37 degrees = 90 degrees - 53.1 degrees

Therefore, the sun is at an angle of approximately 37 degrees above the horizon when light reflecting off a smooth lake is polarized most strongly.

If the mass of the satellite is halved and the distance is doubled, the velocity of the satellite will be reduced to approximately 70.7% of its original value.

In this context, a satellite refers to an artificial object that is launched into orbit around the Earth to perform various functions, such as communication, navigation, and scientific research.

Let's start by writing the equation that relates the velocity of the satellite with its mass and distance from the center of the earth:

v = k√(m/r)

where k is a constant of proportionality.

Now, if the mass is halved and the distance is doubled, we have:

v' = k√(m/2r)

where v' is the new velocity. We can use this equation to find how the velocity is affected by the changes:

v' = k√(m/2r) = k√(m/r) / √2

The square root of 2 is approximately 1.414, so we can simplify the expression to:

v' = v / 1.414

Two people of unequal mass are initially standing still on ice with negligible friction. They then simultaneously push each other horizontally. Then, the statement which is true is the momenta of the two people are of equal magnitude. Thus, the correct option is C.

Momentum is the mass of an object multiplied by its velocity. It is represented by the symbol p. Momentum is a vector quantity and has the same direction as velocity. When the direction of velocity changes, so does the direction of momentum.

The law of conservation of momentum states that the total momentum of an isolated system is constant when no external forces act on the system. According to Newton's third law of motion, when two objects interact, the forces they apply to each other are equal in magnitude and opposite in direction. This implies that the forces on the two people are equal but opposite. Therefore, their momenta are also equal and opposite, so the net momentum of the system is zero after the push.

Kinetic energy is the energy possessed by an object in motion. It is represented by the symbol K. Kinetic energy is a scalar quantity, and it depends on the mass and velocity of the object. When an object moves, it gains kinetic energy, and when it stops, its kinetic energy becomes zero. The kinetic energies of the two people are not equal in this case.

Using the formula P = IV, where P is power, I is current, and V is voltage, we can find the current flowing through the heating coil,

I = P/V = 1500 W/120 V = 12.5 A

To find the resistance of the heater, we can use Ohm's law, which states that V = IR, where V is voltage and R is resistance,

R = V/I = 120 V/12.5 A = 9.6 ohms

To calculate the amount of heat required to raise the temperature of the air in the living room, we can use the formula Q = mcΔT, where Q is heat, m is mass, c is specific heat, and ΔT is the change in temperature.

First, we need to find the mass of the air in the living room. The volume of the living room is 3.00 m × 5.00 m × 8.00 m = 120.00 m^3. Since the density of air is 1.20 kg/m^3, the mass of the air in the living room is,

m = density × volume = 1.20 kg/m^3 × 120.00 m^3 = 144 kg

Next, we can calculate the amount of heat required,

Q = mcΔT = (144 kg)(1006 J/(kg·°C))(10.0°C) = 1.45 × 10^7 J

Finally, we can use the formula Q = Pt, where t is time, to find the time required to generate this amount of heat,

where m is the mass of the person, a is the acceleration of the elevator, g is the acceleration due to gravity (9.8 m/s²), and F is the reading on the scale.

First, we need to convert the reading on the scale from newtons to kilograms:

990 N / 9.8 m/s² = 100.99 kg

Next, we can plug in the values and solve for a:

85 kg(a + 9.8 m/s²) = 100.99 kg(9.8 m/s²)

85 kg(a + 9.8 m/s²) = 989.9 N

a + 9.8 m/s² = 989.9 N / 85 kg

a + 9.8 m/s² = 11.64 m/s²

a = 11.64 m/s² - 9.8 m/s²

Additional types of physical weathering that can happen in colder climates include thermal expansion, which happens when rocks expand and contract as a result of temperature fluctuations, and frost wedging, which happens when water freezes in cracks in rocks and causes them to enlarge. On the other hand, chemical weathering is more prevalent in hotter, wetter regions where there is more water and moisture to support chemical reactions that decompose rocks. Any climate can experience biological weathering, but warm, humid regions with more plant and microbial activity are where it is most likely to happen.

The orbital speed of the second satellite is 6.55 × 10³ m/s.

The formula used to find the orbital speed of a satellite is given as v=√(GM/r).

Therefore, the value of the first satellite's speed is given as v₁=1.89×104 m/s, and the radius is r₁=2.76×106 m. Using the above formula, the mass of the planet is given as:

M= v²r/G= (1.89×104 m/s)² (2.76×106 m)/(6.6743 × 10⁻¹¹ Nm²/kg²) = 5.31 × 10²⁴ kg.

Now, the orbital speed of the second satellite, given as v₂, is equal to:

v₂ = √(GM/r₂); where G = gravitational constant = 6.6743 × 10⁻¹¹ Nm²/kg²;

M = mass of the planet = 5.31 × 10²⁴ kg;

r₂ = radius of orbit of the second satellite = 6.98 × 10⁶ m.

Substituting the values given above, we get:

v₂ = √(GM/r₂)= √[(6.6743 × 10⁻¹¹ Nm²/kg²) × (5.31 × 10²⁴ kg) / (6.98 × 10⁶ m)] = 6.55 × 10³ m/s
