Answer:
10cm^3
Explanation:
Given data
Mass of steel = 80grams
density of steel= 8 g/cm^3
We know that the formula for density is given as
density= mass/volume
make volume subject of formula
volume= mass/density
volume=80/8
volume= 10cm^3
Hence, the volume 10cm^3
Answer:
b. The force exerted by the piston on the object is less than F because the piston is accelerating downward.
Explanation:
Given that object exerts a downward force F on the piston that accelerates the piston downward.
An object can accelerate if the net force acting on it is non-zero.
Here, the piston is acceleration in the downward direction, so the net for on the piston is in the downward direction.
Force due to object, F, is in the downward direction while the force exerted by the piston on the object is in the upward direction.
As the acceleration of the piston is in the downward direction, so the downward force is more.
Therefore, the force exerted by the piston on the object is less than F because the piston is accelerating downward.
Hence, option (b) is correct.
If it didn’t have energy then we wouldn’t be able to move very much and machines will be slower
