The thermal energy in a hot iron flows into a shirt. what can possibly be said about this situation

Rainbow [258]

The correct answer for this question would be option A. When the thermal energy in a hot iron flows into a shirt, what we can possibly say about this situation is that, the iron is warmer than the shirt. The transfer of heat from the iron to the shirt is called heat conduction. Hope this answer helps.

A hunter on level ground fires a bullet at an angle of 2 degrees below the horizontal while simultaneously dropping another bull

Marizza181 [45]

If hunter fires a bullet 2 degree below the horizontal

then the components of its speed is given as

$v_x = v_o cos2$

$v_y = v_o sin2$

so here initial speed of the bullet is not zero but have some magnitude in downwards direction

While the other bullet is dropped downwards so its initial speed will be zero

So here we can say

$d = v_i*t + \frac{1}{2} at^2$

so if we use above equation we will find that the bullet that is shot at 2 degree below the horizontal will reach the ground first as its speed is more
