Answer: The potential energy of the roller coaster increases while climbing up a hill.

Explanation:

Potential energy of the body is defined as the energy of the body due to its position .It is calculated by the formula:

P.E = mgh

Potential energy increase with increase in mass of the body and also increases with increase in the height of the body or the distance between the body and earth surfaces .

So, when the roller coaster climb up the hill the distance between the earth surface and roller coaster increases due to which potential energy also increases.

A long copper wire of radius 0.321 mm has a linear charge density of 0.100 μC/m. Find the electric field at a point 5.00 cm from

krek1111 [17]

Answer:

$E=35921.96N/C$

Explanation:

From the question we are told that:

Radius $r=0.321mm$

Charge Density $\mu=0.100$

Distance $d= 5.00 cm$

Generally the equation for electric field is mathematically given by

$E=\frac{mu}{2\pi E_0r}$

$E=\frac{0.100*10^{-6}}{2*3.142*8.86*10^{-12}*5*10^{-2}}$

$E=35921.96N/C$

anygoal [31]

Answer:

Magnetic substances: steel tank, iron ball, nickel hinge

Non magnetic substances: wooden table, glass marbles, silver medal.

Explanation:

The substances which experience a force of attraction when placed in a magnetic field are called magnetic substances. For example, iron, cobalt and nickel.

The substances which do not experiences a force of attraction when placed in a magnetic field are called non magnetic substances. For example, wood, rubber, glass, etc.
