Assuming that 50% of the initial kinetic energy of the bullet is converted into thermal energy in the bullet and the specific he

DedPeter [7]

Answer:

$\Delta T=\frac{v_{i}^{2}}{4c}$

Explanation:

Let the mass of bullet is m, initial velocity of bullet is vi and c be the specific heat of the bullet.

Kinetic energy, K = 1/2 mvi^2

According to the question, 50% of the kinetic energy is equal to the heat energy absorbed by the bullet.

50% of K = mass of bullet x specific heat x rise in temperature

1/4 mvi^2 = m x c x ΔT

$\Delta T=\frac{v_{i}^{2}}{4c}$

Consider the specific example of a positive charge q moving in the +x direction with the local magnetic field in the +y directio

Leto [7]

Answer:

Therefore the direction is in the positive direction of the z axes.

Explanation:

Let's recall that the magnetic force is given by:

$F_{B}=q(\vec{v} \times \vec{B})$
