Answer:
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.
Answer:
Control Variable
Explanation:
This is because time has to be the same for both materials throughout the experiment (an hour in this case).

Answer:
350 N/m
Explanation:
If we are assuming the stretch does not exceed the elastic range of the material, then by Hooke's law the spring constant of the cord is simply the ratio between the force 70N acting on the cord to stretch 20cm or 0.2m
k = 70 / 0.2 = 350 N/m
The spring constant is 350 N/m
Answer:
Time = 801.802 secs.
Explanation:
Speed can be defined as the rate of change in the magnitude of distance with respect to time. It is a scalar quantity because it only has magnitude but no direction.
Given the following data;
Average speed = 11.1m/s
Time =?
Distance = 8900m
Making time (t) the subject of formula, we have;
Time = 801.802 secs.
<em>Hence, the time the biker takes to cover the segment is 801.802 seconds. </em>
