Which of the following can only be a situation of increasing temperature?

Papessa [141]

Increasing the temperature causes an increase in the average kinetic energy of the particles of a material.

<h3>What is average kinetic energy of particles?</h3>

The average kinetic energy of particles is the energy possessed by particles due to their constant motion.

The constant motion of particles occurs due to the energy acquired by the particles, when the temperature of the particles increases, the average kinetic energy increases which in turn increases the speed of the particles.

Thus, we can conclude that, increasing the temperature causes an increase in the average kinetic energy of the particles of a material.

A soccer player attempting to steal the ball from an opponent was extending her knee at 50 deg/s when her foot struck the oppone

denpristay [2]

Answer:

$\alpha = -4.36 rad/s^2$

Explanation:

Initial angular speed of the player is given as

$\omega = 50 deg/s$

here we know that

$1 deg = \frac{\pi}{180} rad$

now we know that

$\omega = 50\frac{\pi}{180}$

$\omega = 0.87 rad/s$

now its speed comes to zero in 0.2 s

so angular acceleration is given as

$\alpha = \frac{\omega_f - \omega_i}{\Delta t}$

$\alpha = \frac{0 - 0.87 rad/s}{0.2 s}$

$\alpha = -4.36 rad/s^2$
