Ahhh...Net Force.
Net force is simply the overall force acting on an object. Basically, All of the *un*balanced forces acting on that particular object. The Balanced forces cancel each other because they are balanced.
The frequency of sodium light in vacuum is 5 × Hz.
Answer:
Option e
Explanation:
It is known that frequency of a wave is inversely proportional to the wavelength of the wave. And the proportionality constant is the speed of light in vacuum. As the speed of light in vacuum is known as 3× m/s and the wavelength of the light in vacuum is given as 6 × m, then the frequency of the light is determined as
Frequency = Speed of light in vacuum/Wavelength of light
Frequency =
Frequency = 0.5× = 5 × Hz.
So the frequency of sodium light in vacuum is 5 × Hz.
Answer:
Ball with the initial velocity as 15m/s will reach larger distance horizontally on the ground.
Explanation:
Ball 'A' has less initial velocity compared to ball 'B'. Which means it will take more time to reach horizontally on the ground. Therefore, Ball 'A' will cover larger distance.
