Answer:
Yes. the wave is a stationary wave
Amplitude=7.91 cm
Explanation:
We are given that an equation
We have to find that the given wave is a stationary wave or not and find its amplitude at x=2.0 cm
We know that equation of stationary wave
Where
Amplitude=
The given equation is of the form of stationary wave equation.
By comparing we get
Substitute the value of x
Therefore, the amplitude of the wave
Amplitude=
The two will fall at the same speed and reach the surface at the same time. This is because the two will experience the same gravitational acceleration on the moon. However, on the earth surface the two will land on the surface of the earth at the same time due to air resistance such that the egg will experience a higher air resistance than the hammer. On, the moon, where there is no noticeable atmosphere there is no air resistance on either object and both fall at the same speed. It is also important to note that their mass doesn't affect their speed.
Answer:
b)3:2
Explanation:
The dispersive power is the reciprocal of the focal length:
Given the ratio of focal lengths:
Therefore,
P₁ : P₂ = 3 : 2
Hence, the correct option is:
<u>b)3:2</u>
