Answer:
The ground of an antenna needs to be attached to the car in such a way that the voltage of the antenna can connect to the earth. This connection allows the earth to receive and store excess voltage rather than the extra voltage bouncing back through your antenna and radio.

uhhhh idk cheif...
thats a big oof right there.
ged is always an option
An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma).
The scientists should best deal with this measurement by stating that there was an error during measuring and collect further data.
Answer:
4kg
Explanation:
Given parameters:
Kinetic energy = 1.6J
Velocity = 0.2m/s
Unknown:
Mass of the body = ?
Solution:
The kinetic energy of a body is the energy due to the motion of the body.
It is mathematically expressed as;
Kinetic energy = 
m v²
m is the mass
v is the velocity
1.6 = x 0.2 x v²
1.6 = 0.1v²
v² = 16
v = 4kg
