A beaker containing ice and water is placed on a warm hotplate. What type of change would you expect
the ice to undergo​

Answer:

6 Newtons to the left.

Explanation:

We can convert  this into a generic algebra equation by giving directions positive and negative values.

The 6 will be positive, and the 10 and 2 will be negative.

Add 10 and 2 to have 12.

6-12 = -6.

Therefore you have 6 newtons to the left (negative).

Answer:

It takes the Sun's light 7.17 minutes to reach us.

Explanation:

We can calculate the time that takes the light to reach us by using the following equation:

[tex] t = \frac{d}{c} [/tex]    

Where:

d: is the distance = 1.29025x10⁸ km = 1.29025x10¹¹ m

c: si the speed of light = 2.99792x10⁸ m/s  

Hence, the time is:

[tex] t = \frac{d}{c} = \frac{1.29025 \cdot 10^{11} m}{2.99792 \cdot 10^{8} m/s} = 430.38 s = 7.17 min [/tex]

Therefore, it takes the Sun's light 7.17 minutes to reach us.

Answer:

the speed of the sound in the air is 343.3 m/s

Explanation:

The computation of the speed of the sound in the air is shown below:

As we know that

Speed = Distance ÷ time

So, here speed be 515 m

And, the time is 1.50 seconds

So, the speed of the sound is

= 515 m ÷ 1.50 seconds

= 343.3 m/s

hence, the speed of the sound in the air is 343.3 m/s

Answer:

6th amendment

Explanation:

the judge denied her request for a lawyer when she requested one

Answer:

17.35 × 10^(-6) m

Explanation:

Mass; m = 50 kg

Weight; W = 554 N

Now, we know that;

W = mg

Thus; 554 = 50g

g = 554/50

g = 11.08 m/s²

Also, we know that;

mg = GMm/r²

g = GM/r²

Making t the subject gives;

r = √(GM/g)

G has a constant value of 6.67 × 10^(-11) Nm²/kg²

r = √(6.67 × 10^(-11) × 50/11.08)

r = 17.35 × 10^(-6) m

The radius of the saturn is [tex]\bold {17.35 x 10^{-6 }m}[/tex] if  a 50.0-kg mass weighs 554 N.

From Newton's second law,

W = mg  

554 = 50 x g  

g = 554/50  

g = 11.08 m/s²  

Now, Newton's law of gravitation  

[tex]\bold {F=G{\dfrac{m_1m_2}{r^2}}}[/tex]

Where,

F = force

G = gravitational constant = 6.67 x 10^-11 N.m²/kg²

m1 & m2= mass  = M = 50 kg

r = distance between centers of the masses

Put the values and solve it for r,  

[tex]\bold {r = \sqrt {(6.67 x10^{-11} \times \dfrac {50}{11.08}}}\\\\\bold {r = 17.35 x 10^{-6 }m}[/tex]

Therefore, the radius of the saturn is [tex]\bold {17.35 x 10^{-6 }m}[/tex] if  a 50.0-kg mass weighs 554 N.

Is beacuse of the air within our bodys is exerting the same pressure out wards so tjere is no pressure difference

Answer:

it is because our body itself is not  adept enough to resist the air pressure. For every reaction, there be an balanced opposite reaction according to Newton's law. namely, all forces such as air pressure are in proportion therefore we will not perceive air pressure which also means no net force.

Famous French mathematician, physicist, and philosopher Blaise Pascal announced this law in the year 1647.

According to this law, pressure applied to a liquid that is at rest is uniformly distributed throughout.

There are numerous uses for it in daily life. Numerous gadgets, like hydraulic lifts and brakes, are based on Pascal's law.

For incompressible fluids, Pascal's concept is applicable. The majority of vehicle repair shops using lifts use one common use. In essence, air from an air compressor is delivered to the top of oil in a container; the oil then exerts pressure on a sleeve or piston that raises the car.

Answer:

[tex]P(X\ge 1) = 0.9502[/tex]

Explanation:

Given

Density = 3 starts in 10 cubic light years.

Required

Determine the probability of 1 or more in 10 cubic light years

Since the number of stars follow a Poisson distribution, we make use of:

[tex]P(X=k) = f(x) = (\lambda T)^k\frac{ e^{-\lambda T}}{k!}[/tex]

[tex]\lambda = density[/tex]

[tex]\lambda = \frac{3}{10}[/tex]

[tex]\lambda = 0.3[/tex]

T = the light years

[tex]T = 10[/tex]

Calculating [tex]P(X \ge 1)[/tex]

In probability:

[tex]P(X \ge 1) = 1 - P(X = 0)[/tex]

Calculating P(X=0)

Substitute 0 for k and the values for [tex]\lambda[/tex] and T in

[tex]P(X=k) = f(x) = (\lambda T)^k\frac{ e^{-\lambda T}}{k!}[/tex]

[tex]P(X=0) = (0.3* 10)^0 * \frac{ e^{-0.3 * 10}}{0!}[/tex]

[tex]P(X=0) = (3)^0 * \frac{ e^{-0.3 * 10}}{1}[/tex]

[tex]P(X=0) = (3)^0 * e^{-0.3 * 10}[/tex]

[tex]P(X=0) = 1 * e^{-0.3 * 10}[/tex]

[tex]P(X=0) = 1 * e^{-3}[/tex]

[tex]P(X=0) = e^{-3}[/tex]

[tex]P(X=0) = 0.04979[/tex]

Substitute 0.04979 for P(X=0) in [tex]P(X \ge 1) = 1 - P(X = 0)[/tex]

[tex]P(X\ge 1) = 1 - 0.04979[/tex]

[tex]P(X\ge 1) = 0.95021[/tex]

[tex]P(X\ge 1) = 0.9502[/tex] ---  approximated

Hence, the required probability is 0.9502

Answer:

Approximately 92 mm.

Explanation:

Object's distance, u = 110 mm = 11 cm

focal length of the mirror = 5 cm

Image distance, v = ?

To determine the image distance, apply the mirror's formula;

[tex]\frac{1}{f}[/tex] = [tex]\frac{1}{u}[/tex] + [tex]\frac{1}{v}[/tex]

[tex]\frac{1}{v}[/tex] = [tex]\frac{1}{f}[/tex] - [tex]\frac{1}{u}[/tex]

   = [tex]\frac{1}{5}[/tex] - [tex]\frac{1}{11}[/tex]

   = [tex]\frac{11-5}{55}[/tex]

[tex]\frac{1}{v}[/tex] = [tex]\frac{6}{55}[/tex]

⇒ v = [tex]\frac{55}{6}[/tex]

       = 9.166667

v = 9.2 cm

The image distance is 92 mm.

Answer:

Explained below

Explanation:

Newton's first law of motion: This law states that an object will remain at rest or continue in constant motion except it's acted upon by an external force. In projectile motion, the horizontal component of velocity will remain unchanged because we ignore air resistance since no force is acting in that horizontal direction.

Newton's second law of motion: This law states that force is the product of mass and acceleration. In projectile the force acts downwards, thus f = mg.

But g = a since internal forces will cancel out.

Thus, F = ma

A 40-kg person is climbing 3 m up a flight of stairs in 6 seconds. How much work did they do climbing the stairs? answer choices . 400 J. 1200 J. 200 J. 120 J. Tags: Question 13 . SURVEY . 30 seconds . Report an issue . Q. A 40-kg person is climbing 3 m up a flight of stairs in 6 seconds. How much power did they exert climbing the stairs? answer choices . 400 W. 1200 W. 200 W. 120 W. Tags

200 W was used in climbing the stairs.

We'll begin by calculating the energy. This can be obtained as follow:

Mass (m) = 40 kg

Height (h) = 3 m

Acceleration due to gravity (g) = 10 m/s²

E = 40 × 10 × 3

Finally, we shall determine the power exert in climbing the stairs. This can be obtained as follow:

Energy (E) = 1200 J  

Time (t) = 6 s

[tex]Power = \frac{Energy }{Time}\\\\Power = \frac{1200}{6}[/tex]

Thus, 200 W was used in climbing the stairs.
