A spring is stretched downward by a certain length and, as a result, exerts a
force in the upward direction. What happens to the force exerted by the
spring if the length by which it is stretched is reduced by half?
O A. The force exerted by the spring is reduced by half.
B. The force exerted by the spring is doubled.
O C. The force exerted by the spring reduced by one quarter.
O D. The force exerted by the spring remains unchanged.

Answers

Answer:

A

Explanation:

Hooke's law! F(spring)=-kx

There's no tricky square law here. The spring constant doesn't change, only x (distance stretched) changes. Therefore, if distance is halved, Force will be halved.

i dont understand ..............

Answers

Take the upward and to-the-right directions to be positive (so down and to-the-left are negative).

The vertical forces acting on the object cancel, 6 N - 6 N = 0.

The horizontal forces exert a net force of 20 N - 3 N = 17 N. This net force is positive, so it points to the right. So the answer is A.

Please answer this question.

Answers

Answer:

150.15 J

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 5 kg

Height (h) = 3 m

Kinetic energy (KE) =?

Next, we shall determine the velocity of the toy before hitting the ground. This can be obtained as follow:

Initial velocity (u) = 0 m/s

Height (h) = 3 m

Acceleration due to gravity (g) = 9.8 m/s²

Final velocity (v) =?

v² = u² + 2gh

v² = 0² + (2 × 10 × 3)

v² = 0 + 60

v² = 60

Take the square root of both side

v = √60

v = 7.75 m/s

Thus, the velocity of the toy before hitting the ground is 7.75 m/s.

Finally, we shall determine the kinetic energy of the toy before hitting the ground. This can be obtained as follow:

Mass (m) = 5 kg

Velocity (v) = 7.75 m/s.

Kinetic energy (KE) =?

KE = ½mv²

KE = ½ × 5 × 7.75²

KE = 2.5 × 60.06

KE = 150.15 J

Thus, the kinetic energy of the toy before hitting the ground is 150.15 J

An automobile of mass 1.46 E3 kg rounds a curve of radius 25.0 m with a velocity of 15.0 m/s. The
centripetal force exerted on the automobile while rounding the curve is:

Answers

Answer:

Centripetal force = 13140 Newton.

Explanation:

Given the following data;

Mass = 1.46 E3 kg = 1.46*10³ = 1460 kg

Velocity = 15m/s

Radius, r = 25m

To find the centripetal force, we would use the following formula:

Centripetal force = mv²/r

Substituting into the equation, we have;

Centripetal force = (1460*15²)/25

Centripetal force = (1460 * 225)/25

Centripetal force = 328500/25

Centripetal force = 13140 Newton.

Answers

Answer:

1. The elastic potential energy is 0.0176 Joules

2. The kinetic energy of the pinball the instant it leaves the spring is 0.0176 Joules

3. The speed of the pinball the instant it leaves the spring is approximately 2.42212 m/s

4. The height of the part where the pinball is located on the machine above the ground is approximately 0.213 meters

Explanation:

The spring constant of the pinball machine's plunger, k = 22 N/m

The amount by which the pinball machine's plunger is compressed, x = 0.04 m

The mass of the pinball ball, m = 0.006 kg

1. The elastic potential energy, P.E. = 1/2·k·x²

By substitution, we get;

P.E. = 1/2 × 22 N/m × (0.04 m)² = 0.0176 J

The elastic potential energy, P.E. = 0.0176 J

2. At the instant the pinball leaves the spring, the plunger and therefore the force of the plunger no longer acts on the pinball

Since there are no external forces acting on the pinball to increase the speed of the pinball after it leaves the spring, the velocity reached is its maximum velocity, and therefore, the kinetic energy, K.E. is the maximum kinetic energy which by the conservation of energy, is equal to the initial potential energy

Therefore;

K.E. = P.E. = 0.0176 J

The kinetic energy of the pinball the instant it leaves the spring, K.E.= 0.0176 J

3. The kinetic energy, K.E., is given by the following formula;

K.E. = 1/2·m·v²

Where;

v = The speed or velocity of the object having kinetic energy K.E.

Therefore, from K.E. = 0.0176 J, and by plugging in the values of the variables, we have;

K.E. = 0.0176 J = 1/2 × 0.006 kg × v²

v² = 0.0176 J/(1/2 × 0.006 kg) = 88/15 m²/s²

v = √(88/15 m²/s²) ≈ (2·√330)/15 m/s ≈ 2.42212 m/s

The speed of the pinball the instant it leaves the spring, v ≈ 2.42212 m/s

4. The height of the pinball is given by the following kinematic equation of motion;

[tex]v_h[/tex]² = u² - 2·g·h

Where;

[tex]v_h[/tex] = The velocity of the pinball at the given height = 1.3 m/s

u = v ≈ 2.42212 m/s (The initial velocity of the pinball as it the spring)

g = The acceleration due to gravity ≈ 9.8 m/s²

h = The height of the pinball above the ground

We get;

[tex]v_h[/tex]² = 1.3² = 2.42212² - 2 × 9.8 × h

∴  h = (2.42212² - 1.3²)/(2 × 9.8) ≈ 0.213

The height of the part where the pinball is located on the machine above the ground, h ≈ 0.213 m

What type of force causes the motion of an object to change

what physical properties dose plutonium

Answers

Answer:

Explanation:

Plutonium-239 is one of the two fissile materials used for the production of nuclear weapons and in some nuclear reactors as a source of energy. The other fissile material is uranium-235. Plutonium-239 is virtually nonexistent in nature. It is made by bombarding uranium-238 with neutrons in a nuclear reactor. Uranium-238 is present in quantity in most reactor fuel; hence plutonium-239 is continuously made in these reactors. Since plutonium-239 can itself be split by neutrons to release energy, plutonium-239 provides a portion of the energy generation in a nuclear reactor.

A 0.144 kg baseball approaches a batter with a speed of 20m/s . The batter lines the ball directly back to the pitcher with a speed of 30m/s . Find the impulse exerted on the ball . If the bat and ball were in contact for 0.012 sec , find the average force exerted on the ball by the bat

Answers

Answer:

The impulse exerted by the ball is 7.2 kg.m/sThe average force exerted on the ball by the bat is 600 N.

Explanation:

Given;

mass of the baseball, m = 0.144 kg

velocity of the baseball, v₁ = 20 m/s

velocity of the batter, v₂ = -30 m/s (opposite direction to the ball's speed)

The impulse exerted by the ball is calculated as follows;

J = ΔP = mv₁ - mv₂

ΔP = m(v₁ - v₂)

ΔP = 0.144 [20 - (-30)]

ΔP = 0.144 ( 20 + 30 )

ΔP = 0.144 (50)

ΔP = 7.2 kg.m/s

The average force exerted on the ball by the bat is calculated as;

[tex]F = \frac{\Delta P }{t} \\\\where; t \ is \ time \ of \ contact= 0.012 \ s\\\\F = \frac{7.2}{0.012} \\\\F = 600 \ N[/tex]

How does the force that causes the water to leave the rocket compare to the force that causes the rocket to launch?
They are ental

Answers

Answer:They are equal and act in opposite directions.

Explanation:Newton's third law of motion states that for every action there is an equal and opposite reaction. In the case of Bode's rocket, the pressurized air in the bottle forces the water to gush downward out of the bottle, causing the rocket to launch upward into the air. The force of the water gushing downward is equal to the upward force on the rocket. So, the two forces are equal and act in opposite directions.

The force that causes the water to leave the rocket compared to the force that causes the force to launch is equal but opposite in direction.

What is Newton's law?

There is a threes law given by the scientist newton in relation to the motion. The first law tells that if a body is in stop mode, then they become in motion once an external force is applied to them. The second law tells that force is equal to the product of mass and acceleration of the body. The third law tells that if you apply force to an object, then the object also applies force in reaction.

According to Newton's third law, the rocket applies force to the water, then the water also exerts a force on the rocket.

In the instance of Bode's rocket, the bottle's pressured air causes the water to pour out of the bottle downward, which causes the rocket to shoot upward into the air. The upward force on the rocket is equivalent to the force of the water pouring down. Therefore, the two forces are equivalent and exert opposing forces.
