Answer:
10m/s
Explanation:
Using the law of conservation of momentums
M1u1+m2u2 = (m1+m2)v
Substitute.
4000(10)+1500(10) = (4000+1500)v
40,000+15,000 = 5,500v
55000 = 5500v
v = 55000/5500
v= 10m/s
Hence the velocity of the truck after Collision is 10m/s
Answer:
the light will reflect parallel to the principal axis
The resolution of a camera or other optical system is determined by the relationship between that two scales of Light waves of different wavelengths produce diverse colors.
A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles. This length is typically defined in wireless systems in meters (m), centimeters (cm), or millimeters (mm) (mm).
The distance between the crests or troughs of a wave motion is referred to as the wavelength () of light. 2. Frequency (f) - The frequency of a repeated event is the number of instances per unit of time. Frequency in the context of light is the number of wavelength repetitions per second.

The ball would move about, 674 kilometers. I think I’m correct. Somebody correct me if I’m not.
The answer is modulation. In modulation a radio wave (also called the "carrier signal") is changed by the signal we want to send to the receiver, for example a song, or, in a wireless network, some data from a computer.
