Answer:
how large a magnetic field would you experience = 8.16 x 10∧-4T
Explanation:
I = 20KA = 20,000A
r = 4.9 m
how large a magnetic field would you experience = u.I/2πr
how large a magnetic field would you experience = (4π x10∧-7) × 20000/2π × 4.9
how large a magnetic field would you experience = 8.16 x 10∧-4T
Copper, gold and silver are three of them.
Answer:
Venus and Earth
Explanation:
The force of gravity depends on your mass AND the mass of the planet you stand on. Earth and Venus are about the same size, so they have about the same mass. If you go to Venus, your mass hasn't changed, and the planet mass is almost the same as earth- so the force of gravity on you (AKA your weight) will be the same.
The mass of the iceberg is 71.9 kg
Explanation:
The amount of thermal energy needed to completely melt a substance at its melting point is given by
where
is the latent heat of fusion
m is the mass of the substance
In this problem, we have a block of ice at its melting point (zero degrees). The amount of heat given to the block is
And the latent heat of fusion of ice is
So, we can re-arrange the equation to find m, the amount of ice that will melt:
