Speed = (wavelength) x (frequency
Speed = (.020 m) x (5 / sec)
Speed = 0.1 m/s
Answer:
B) The amount of time the torque is applied to the disk, because the time interval is related to the angular impulse of the disk.
Explanation:
Angular impulse = Torque x time
= change in angular momentum
So,
Torque x time = change in angular momentum
change in angular momentum = Torque x time
Torque is already known .
Hence to know the change in angular momentum what is needed to know is time duration of torque acting on the body .
Answer:
its 1
Explanation:
Several factors can increase the rate of a chemical reaction. In general, anything that increases the number of collisions between particles will increase the reaction rate, and anything that decreases the number of collisions between particles will decrease the chemical reaction rate.

Answer:
Explanation:
Force needed to apply start the box is greater than the force needed to keep it moving because static friction is greater than the kinetic friction .
A threshold force is needed to move the box and when box started to move kinetic friction comes into play.
Friction force is directly related to the weight of the box as the friction force is
coefficient of friction time Normal reaction .
And Normal reaction is equal to the weight of box if no force is applied.
