Answer:
It reveals that light is a wave
Explanation:
Diffraction is the property of a wave in which there is a bending of the wave about the corners of an obstacle or aperture into the geometrical shadow of the obstacle or aperture.
This simply implies that a wave bends or spreads out when it passes through openings. Since the light diffracts through small slits and diffraction has been shown to occur in water waves and sound waves, this property of diffraction can only be characteristic of a wave and thus, this evidence reveals that light is a wave.
Answer: If a velocity time graph is horizontal then the velocity is constant and there is no acceleration.
Answer:
The compress of the spring is 0.495.
Explanation:
Given that,
Mass = 50 kg
Spring constant = 8000 N/m
height = 2.0 m
We need to calculate the compress of the spring
Using law of conservation of energy
Where, m = mass
g = acceleration due to gravity
h = height
k = spring constant
x = distance
Put the value into the formula
Hence, The compress of the spring is 0.495.
Answer:
Explanation:
As per Faraday's law of Electromagnetic induction we know that
Rate of change in magnetic flux will induce EMF in the closed conducting loop
so we have
now we have
now we have
now the induced EMF through this loop is given as
A She can run the same distance in a shorter amount of time.
Explanation:
Speed is a physical quantity that expresses the rate of change of distance with time:
Speed =
We can see that speed will increase if the distance covered increases with a decreasing amount of time.
Speed will decrease if the distance decreases with increasing time
Speed will increase if the distance covered stays the same with decreasing time
Speed will reduce if the distance covered stays the same with increasing time.
