Answer: acceleration = -10m/s^2
Explanation:
Use Fab 5 equation to solve for acceleration. (Use equation without d/distance because it is irrelevant for this particular question)
vi = 60m/s
vf = 0m/s because car comes to a stop
t = 6s
a = ?
d = irrelevant
Use a = vf-vi/t
Step by step solution:
a = vf - vi / t
a = 0 - 60 / 6
a = -60 / 6
a = -10m/s^2
Hope this helps! :)
It all comes to the doppler effect, the red shift means that the galaxy is moving away from us. The redshift is a result from the doppler effect, so as the galaxy moves away the wavelength expands, increasing the wavelength which responds to the red light.
Answer:
a) 2.933 m
b) 4.534 m
Explanation:
We're given the equation
v(t) = -0.4t² + 2t
If we're to find the distance, then we'd have to integrate the velocity, since integration of velocity gives distance, just as differentiation of distance gives velocity.
See attachment for the calculations
The conclusion of the attachment will be
7.467 - 2.933 and that is 4.534 m
Thus, The distance it travels in the second 2 sec is 4.534 m
Answer:
assuming ur speaking about chemistry
c=frequency×wavelength
or
energy=frequency×h
Answer: The passage of a light wave can cause electrically charged particles to move up and down.
Explanation:
Electromagnetic waves are transversal waves, they are a combination of oscillating electric and magnetic fields, which propagate through space carrying energy from one place to another.
This means the oscillation of the wave occurs in the transversal direction to its propagation. In addition, electromagnetic waves are spread thanks to the electromagnetic fields produced by moving electric charges.
