PE is mgh in this context.
Answer:
L^2T^-1
Explanation:
a = vr
The dimension of v is LT^-1
The dimension of r is L
Therefore, the dimension of a = LT^-1 × L = L^2T^-1
To find the mass and volume of irregularly shaped object. One can use the balance to find the weight, and to find the volume of the object water should be poured in the beaker and note the level of water.
Answer:
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
Water atoms move more easily than ice
Ice is in a fixed crystal structure, it obviously has a lower temperature than liquid water, the state does not determine the charge, and when water freezes the crystalline structure actually makes it less dense than liquid because atoms are evenly spaced apart.
