Does a negative charge indicates a lack of free electrons in a body.

Answers

Answer 1

Answer: No. Electrons are negative, so if a body has negative charge is because it has excess of electrons.

A company is creating a new cylindrical container to replace its original cylindrical container.´ The new container will have 4 times the volume of the original container.

´ The height of the new container will remain the same as the height of the original container.

The length of the radius of the new container will be -

f 4 times the length of the radius of the original container
g 8 times the length of the radius of the original container
h 2 times the length of the radius of the original container
j 16 times the length of the radius of the original container

Answers

The correct option is h. " 2 times the length of the radius of the original container"

Reason:
V(old) = pi r^2 h ... r = old radius
V(new) = 4pi r^2 h = pi R^2 h R = new radius
4pi r^2 h = pi R^2 h ... pi and h cancel
4r^2 = R^2
R = 2r

A roller coaster with a potential energy of 235,200 J sits at the top of a 30 m high hill. What is the mass of the roller coaster? (Formula: PE = mgh)

Answers

A roller coaster with a potential energy of 235,200 J and sits at the top of a 30 m high hill has a mass equivalent to 799.18 kg. Using the formula of PE = mgh, all of the values are already known, so direct substitution can be used. PE is the potential energy, m is the mass, g is gravitational constant (9.81 m/s2), and h is the height.

Answer: its 800 kg thank me later ;)
