Answer:
Doppler blueshift
Explanation:
is used in astronomy to determine relative motion: The Andromeda Galaxy is moving toward our own Milky Way galaxy within the Local Group; thus, when observed from Earth, its light is undergoing a blueshift.
<span>To find the amount of work done by a force acting on a moving object, we can use this simple equation:
W = F * d * cos(theta)
W is Work
F is the force
d is the distance the object moves
theta is the angle between the force vector and the direction of motion
We know that (F * d) is 190 joules. We can find the work done when the angle is 56°.
W = F * d * cos(theta)
W = (190 J) * cos(56°)
W = 106 J
At an angle of 56°, the work done by the force is 106 joules.</span>
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.
