Answer:
Explanation:
The radial velocity method involves watching the spectral lines of a star as a planet orbits the star. Because of the planets gravitational pull on the star, the star will wobble. This causes Doppler shifts in the spectral lines, allowing astronomers to infer the presence of the planets.
Answer: High tide

Answer:
c.The two balls will have the same speed.
Explanation:
When two balls green and blue both are moving with initial velocity 10m/s.
The green ball has been tossed upward and blue ball downwards.
Air resistance is negligible means there is no force which oppose the motion of balls.
When blue balls has been tossed downward then the blue ball will move under the gravity.
When green fall downward then the ball falls under the gravity because there is no air resistance.
Therefore, both balls move with acceleration due to gravity when they wil reach at ground.
Therefore, the velocity of both balls are same.
Hence, the two balls will have the same speed.
Option c is true.
The distance between new york city, new york and los angeles, California in miles is: c. 2787 miles
To solve this problem we have to do the conversion of units with the given information.
Information about the problem:
- d(between new york and los angeles) = 4485 kilometers
- 1 mile = 1.609 kilometers
- d (between new york and los angeles) in miles=?
By converting the distance units from kilometers to miles we have:
d(between new york and los angeles) = 4485 kilometers * 1 mile/1.609 kilometers
d(between new york and los angeles) = 2787.4 miles
Rounding to the nearest mile we get:
d(between new york and los angeles) = 2787 miles
<h3>What is unit conversion?</h3>
It is the transformation of a value expressed in one unit of measurement into an equivalent value expressed in another unit of measurement of the same nature.

Answer:
that best describes the process is C
Explanation:
This problem is a calorimeter process where the heat given off by one body is equal to the heat absorbed by the other.
Heat absorbed by the smallest container
Q_c = m ce (
-T₀)
Heat released by the largest container is
Q_a = M ce (T_{i}-T_{f})
how
Q_c = Q_a
m (T_{f}-T₀) = M (T_{i} - T_{f})
Therefore, we see that the smaller container has less thermal energy and when placed in contact with the larger one, it absorbs part of the heat from it until the thermal energy of the two containers is the same.
Of the final statements, the one that best describes the process is C
since it talks about the thermal energy and the heat that is transferred in the process
