A) the piano lost mass as it was pushed up the ramp.
B) energy was destroyed moving the piano up the ramp.
C) some of the energy required to push the piano up the ramp was used to overcome friction between the piano and the ramp.
D) the work required to push the piano up a ramp is greater because the force is the same as if it were lifted, but the distance is greater when using a ramp.
Answer:
c

Answer:
Work done by the force is 1000 Joules
Explanation:
The relation ship between the variables is as follows:
(Work W) = (Force F) x (Displacement d) = (Mass m) x (Accelleration a) x (Displacement d)
so:
If a rock is placed into a graduated cylinder containing 80 mL of water. then the volume of the rock would be 40 if the water level rises to the 120 mL mark
It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
the density of the rock = mass of the rock /volume of the rock
As given in the problem A rock is placed into a graduated cylinder containing 80 mL of water.
The volume of the rock =120 milliliter - 80 milliliter
= 40 milliliter
Thus, the volume of the rock would be 40 milliliters.

Answer:
Newton's second Law states that an object's acceleration is directly related to the net force applied and inversely related to the mass of the object.
Explanation:
Newton's second law states that when force is applied on an object, then it causes acceleration which is directly dependent on the net force applied and varies inversely with the mass of the object.
This law gives us the following equation:
where represents net force applied, represents mass of the object and represents acceleration caused.
The above equation can be rearranged to:
This equation shows that acceleration is directly dependent on net force and inversely dependent on mass of the body.
