Using a lever
Determine that the longer end of a lever travels farther and faster than the shorter end when the fulcrum is not in the centre. A baseball or cricket bat makes use of this benefit. List other examples of the use of levers and other simple machines to enhance speed.
A glass sphere of radius 15 cm has a small air bubble at a distance of 6 cm from its centre. When viewed normally along its diameter from the nearest side, the bubble seems to be 7
The electric field strength, defined as a force per unit charge, has the units Newton per coulomb, N/C. The formula for electric potential difference, ΔV = Ed, though, suggest
Explain the term- Zener Breakdown Under a very high reverse voltage, depletion region expands and potential barrier increases resulting in a very high electric field (3X10 7
Two wires on a piano are the same length and are pulled by the same tension. wire 1 vibrates at a frequency 1.5 times the frequency of wire 2. Calculate the ratio of their masses (
