After ten minutes, the chili is cool enough for him to eat.

what has happened to the chili's thermal energy?

Chilli thermal energy is transferred to the surrounding air and other objects in the surrounding either by convection or Radiation

Explanation:

As we know that chilli is put at high temperature in the room and hence the thermal energy will transfer from high temperature to low temperature.

So after some time the chilli is cooled down due to sufficient transfer of energy from chilli to the surrounding particles.

All the energy is transferred either by convection mode of heat transfer by air molecules or it is transferred by radiation.

so due to this transfer of energy to the surrounding the chilli temperature becomes lower.

choosing tennis and golf balls is your inde choice.

their mass and volume are dep

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
