Dimensionally, an acceleration is:

5 / 30

An electric current I flows for a time t through a conductor with a potential difference V across it. The energy dissipated is:

6 / 30

A body A is at a higher temperature than a body B. This means that:

7 / 30

A vessel of water stands on a balance, which reads a weight P₀. A small iron sphere is immersed in the water and held from outside by a string so that it is fully submerged without touching the bottom. The balance reading becomes:
