Acceleration is the change in velocity over time
You don't say what the insulators are insulating from ... heat or electricity.
Here are some of each:
Heat insulators:
-- Air (between the inner and outer bottles of a thermos bottle)
-- Wood (around the handle of a frying pan)
-- Cloth (an oven mitt)
Electrical insulators:
-- rubber
-- plastic
-- wood
-- cloth
-- air

Hey mate, here is your answer answer. Hope it helps you
Explanation:
1. If a worker has come into contact with electricity the worker may not be able to remove themselves from the electrical source. The human body is a good conductor of electricity. If you touch a person while they are in contact with the electrical source, the electricity will flow through your body causing electrical shock. Firstly attempt to turn off the source of the electricity (disconnect). If the electrical source can not readily and safely be turned off, use a non-conducting object, such as a fibreglass object or a wooden pole, to remove the person from the electrical source.
2. C- Electrical energy.The term electrical activity means that the food itself has the power to generate electric energy that persists some period of time. This work presents a purely renewable energy as energy comes. the zinc reacts with food tissue.
This one is a piece 'o cake if you know the formula for
Kinetic Energy, and impossible if you don't.
It is: KE = (1/2) (mass) (speed²) .
For this object: KE = (1/2) (30 kg) (20 m/s)²
= (1/2) (30 kg) (400 m²/s²)
= (15 x 400) (kg-m²/s²)
= 6,000 joules .
