Answer:
0.05 cm
Explanation:
The compression of the original spring = 12 - 8.55 cm = 3.45 cm = 0.0345 m
By Hooke's law, F = ke
Where F is the applied force, k is the spring constant and e is the extension or compression. In the question, F is the weight of the car.
k = F/e = 1355 × 9.8 / 0.0345 = 384898.55 N/m
This is the spring constant of the original spring. The question mentions that the force constant of the new spring is 5855.00 N/m smaller. Hence, the force constant of the new spring is 384898.55 - 5855 = 379043.55 N/m
With the new spring installed, the compression will be
e = F/k = 1355 × 9.8 / 379043.55 = 0.035 m = 3.5 cm
The difference in the compressions of both springs = 3.5 cm - 3.45 cm = 0.05 cm
Answer:
geothermal energy
Explanation:
the energy is obtained from the heat within the surface of earth

Answer:
The weight is the same
3
lb
explanation
See explanation.
Explanation:
If by weight you mean the physical value measured in
l
b (or k
g
) usually called mass, then this value does not depend on a place where object is located. Object's mass would be the same everywhere even if you put it on Mars or the Sun.
The value which changes is the gravitational force. In your example it is

100 times greater on the Earth's surface than in the point 10 Earth's radii from its center.
Answer:
The ball is in the air for approximately 0.45 seconds
Explanation:
We only need to use the information on the height of the table to find the time, since the vertical movement is a movement under the acceleration of gravity, and with no initial velocity in the y-direction (recall that the ball rolls off a 1.0 m high table)
therefore the equation of motion for the vertical component is:
which for our information becomes:
