Answer:

so this is nearly red colour light
Explanation:
As we know that the interference of light from reflected light then the path difference is given as

now we know that for constructive interference of light the path difference is given as

so we will have

so we will have



so this is nearly red colour light
The density of the body and the height or the depth of the body since the formula of liquid pressure is density x height gravity
Answer:
F = 400 N
Explanation:
Given,
The acceleration of the car, a = 8 m/s²
The mass of the passenger, m = 50 Kg
The force acting on a body is equal to the product of the mass and its acceleration
F = m x a newtons
Substituting the given values in the above equation,
F = 50 Kg x 8 m/s²
= 400 N
Hence, the force exerted by the person on the seat belt is, F = 400 N
What the equation given?
- x(t)=Acos
t
Maximum velocity occurs at the equilibrium position
So
Now
Now
As we know the formula

These expressions can be used
