Answer:
a) amount of kinetic energy converted to internal energy = 2.5 x 10 raised to power 7 Joule
b) Kinetic energy gained by the earth = 2.1 x 10-16J
c) All the kinetic energy is converted to internal energy and the energy is further converted to thermal energy hence the reason for the hotness at around where the meteorite strikes.
Explanation:
The detailed steps and appropriate application of the law of conservation of momentum is as shown in the attached file.
Answer:
M v^2 / R = centripetal force
For Red: M v^2 / R = 5 * 9^2 / 1.5 = 270
For Blue M v^2 / R = 270 = 25 * 1.8^2 / Rb
So Rb = 25 * 1.8^2 / 270 = .3 m
Answer:
The total magnetic force is 0.297 N.
Explanation:
Given that,
Current = 2.0 A
Length of each side = 15 cm
Magnetic field = 0.7 T
A loop of wire is in the shape of a right triangle with two equal sides.
The angle between the magnetic field and both the sides of the triangle is 45 degrees.
We need to calculate the total magnetic force
Using formula of magnetic force

Where, B = magnetic field
I = current
L- length
Put the value into the formula


Hence, The total magnetic force is 0.297 N.
To determine the amount in grams of the iron, we need data on the density of iron. From literature, it has a value of <span>p=7.9 g/cm3. We simply multiply the volume to the density. We do as follows:
mass = 3.70 (7.9) = 29.23 g Fe
Hope this answers the question. Have a nice day.</span>
Answer:
It is because of the blood pressure balances with our atmospheric pressure
