energy is the energy of the motion or vibration of molecules in a substance.
The answer is letter A. A wrecking ball on its way down before it hits a
building is an example of kinetic energy being converted into mechanical energy.
The answer is letter D.</span>
I truly believe so, that’s a definite yes
Answer:
The height of a tower would be 27.5 meters
Explanation:
Notice that in both cases you are dealing with diagrams representing vertical objects and shadows created by the sun, against the ground, so we are in the presence of right angle triangles which have in common another angle (that made by the rays of the sun. So we can use similar triangles and the proportion that is generated based on the quotient of similar sides to find the unknown height (h).
Answer:
option (b)
Explanation:
Let the electric field is given by E.
mass of proton = mp
mass of electron = me
acceleration of proton = ap
acceleration of electron = ae
Charge on both the particle is same but opposite in nature.
The force on proton = q E
The force on electron = - q E
acceleration of proton, ap = q E / mp
acceleration of electron, ae = - q E / me
We observe that the force is same in magnitude but opposite in direction, acceleration is also different and opposite in direction.
