Answer:
The wavelength of observed light on earth is 568.5 nm
Explanation:
Given that,
Velocity of spaceship
Wavelength of laser
We need to calculate the wavelength of observed light on earth
Using formula of wavelength
Hence, The wavelength of observed light on earth is 568.5 nm
Answer:
20.88 m/s
Explanation:
Curve A:
theta = 12.7, vA = 19.1 m/s
Curve B:
Theta = 15.1 degree
Let the speed is v.
By the use of given formula
tanθ = v^2 / rg
For Curve A
tan 12.7 = (19.1)^2 / r g ...... (1)
For Curve B
tan 15.1 = v^2 / r g ......(2)
Divide equation (2) by equation (1), we get
tan 15.1 / tan 12.7 = v^2 / (19.1)^2
0.269 / 0.225 = v^2 / 364.81
v = 20.88 m/s
It transfers energy through the source of the sound. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate
Answer: The horizontal location of the plane will BE OVER THE BOMB
Explanation:
As soon as the bomb was dropped, the bomb will fall under gravity (free fall) and the location of the plane continues to increase horizontally till the bomb reaches the ground which is a falling distance to be travelled by the bomb at 9.8m/s²
