The momentum of the car is 60,000 kg m/s
Explanation:
The momentum of an object is a vector quantity, whose magnitude is given by
where
m is the mass of the object
v is its velocity
For the car in this problem, we have
m = 2,000 kg
v = 30 m/s
Therefore, the magnitude of its momentum is

Explanation:i’m pretty sure
Answer:in X-rays
Radiation are used in X-rays for the treatment of tumours, and some skin diseases,cancer cells can be destroyed by X-rays
Answer:
Going by EM SPECTRUM WE HAVE
radio waves, microwaves, infrared, VISIBLE LIGHT, ultraviolet, X-rays, GAMMA RAYS
BECAUSE
V= WAVELENGTH/ FREQUENCY
AS FREQUENCY INCREASES WAVELENGTH DECREASE AN VICE VERSA
