Answer:
Grounded used to carry the current in the normal conditions. while on the other side grounding is refer to that safety wire that is connected to the earth and currently does not transmit through it.
As grounding wire is referred to as safety wire hence it carries current only in an emergency like a short circuit.
Explanation:
A grounded conductor is referred to as one of the wire that needed in an electric circuit. it is basically a neutral conductor. It used to carry the current in the normal conditions. while on the other side grounding is refer to that safety wire that is connected to the earth and currently does not transmit through it.
As grounding wire is referred to as safety wire hence it carries current only in an emergency like a short circuit.
Answer:
78.498N
Explanation:
The Net force provided by the spinnaker can be obtained from Newton's second law of motion as follows;
where m is the mass, v is the final velocity, u is the initial velocity and t is the time interval for which the force acted.
Given;
m =980lb
v = 12mi/h
u =8mi/hr
t = 10s.
It is important to convert all quantities to their SI units where necessary, so we do that as follows;
1lb = 0.45kg,
hence 980lb = 980 x 0.45kg = 441kg.
1mile = 1609.34m
1hour = 3600s,
therefore;
Substituting all values into equation (1), we obtain the following;
<u>Conductivity</u> is the property of matter in which a substance can transfer heat or electricity.

Matter : Anything which occupies space and has mass is called matter.
<u>Chemical classifications</u>
- Pure Substances ( made of one kind of substance )
- Impure Substances ( mixture )
<u>Physical</u><u> </u><u>classifications</u><u> </u>
- Plasma ( made of ions and free electrons )
- BEC ( Bose Einstein Condensate )
- Fermionic Condensate ( It discovered in 2003 )
A scientific law is a principle that describes the behavior of a natural phenomenon.

Repeat the experiment
Explanation:
To increase the validity of the results obtained from the single experiment, the students should be encouraged to repeat the experiments more number of times as much as possible.
In an experiment, scientist always try to limit errors by making precise and accurate observation. A single observation does not really represent a precise and accurate finding. When an experiment is repeated as often as possible, the reliability of the conclusion drawn from the hypothesis testing will improve and the results can be accepted to be valid.
A single observation/experiment is not valid enough.
