A 5.6 MeV (kinetic energy) proton enters a 0.39 T field, in a plane perpendicular to the field. What is the radius of its path?

Kisachek [45]

Answer:

the radius of the protons path is r = 0.85 m.

Explanation:

the force due to magnetic fields lead to the cetripetal force, such that:

F = q×v×B = m×(v^2)/r

q×B = m×v/r

then:

r = m×v/q×B

r = p/q×B

then, the kinetic energy of the proton:

K = 1/2×m×v^2 = p^2/(2×m)

q×B = \sqrt{2×m×K}/r

r = \sqrt{2×m×K}/(q×B)

= \sqrt{2×(1.67×10^-27)×(5.3×1.60×10^-13)}/(1.60×10^-19×0.39)

= 0.85 m

Explain why color is a measure of a star’s temperature.

guajiro [1.7K]

Answer: The color of a star plays a significant role in determining its age as well as its temperature. A star normally appears to be shining as we see through the atmosphere. An increase in the temperature of a star releases more energy and this can be observed in the various colors of color spectrum.

The hottest star generally appears to be bluish-white in color whereas the coldest star usually appears to be reddish in color.

Thus, a star's color can help us determining its temperature.

In the absence of air resistance, a ball is thrown vertically upward with a certain initial KE. When air resistane is a factor a

Ber [7]

Answer:

Explanation:

A ball is thrown vertically upward with a certain Kinetic Energy in the absence of air resistance and while returning it experiences air resistance.

Air resistance causes the ball to lose its kinetic energy as it provides resistance which will convert some of its kinetic energy to heat energy.

So in a way total energy is conserved but not kinetic energy as some portion of it is lost in the form of heat.
