Answer:
C
Explanation:
Which wavelength of the electromagnetic spectrum are shorter than visible light and carry more energy
A micro
B radio
C ultraviolet
F infrared
The correct answer is C
The visible light wavelength is of 7 × 10^-7 m while the ultraviolet is of other
4 × 10^-8 m
Therefore, ultravolet is shorter than visible light and carry more energy
Therefore, the correct answer is option C.

Answer:
330Ns
Explanation:
Given parameters:
Mass of the box = 5kg
Initial velocity = 0m/s
Force applied = 15N
Time = 22s
Unknown:
Impulse = ?
Final momentum = ?
Solution:
The impulse of the box can be determined using the expression below:
Impulse = Force x time
Impulse = 15 x 22 = 330Ns
The final momentum is the same as this impulse
The impulse and the final momentum is 330Ns
Angular acceleration = (change in angular speed) / (time for the change)
Change in angular speed = (ending speed) minus (starting speed)
Change in angular speed = (16 rad/s) - (zero) = 16 rad/s .
Angular acceleration = (16 rad/s) / (0.4 s)
(Average) angular acceleration = 40 rad/s²
