Answer:
66.053m/s
Explanation:
A = 47
B = 347
C = 19
Train moves at
(23 + A)m/s
= 23 + 47 = 60m/s
At (250.0+B) seconds
250.0+347 =
547 seconds
Distance d,
= 70 x 597
= 41790
It also moves at
(45.0 + c)
= 45 + 19
= 64m/s
Time = 800 + B
= 800 + 347
= 1147
Distance,
= 64 x 1147
= 73408m
Total distance,
= 73408 + 41790
= 115,198
Total time,
= 597 + 1147
= 1744
Average speed,
= Total distance / total time
= 115198/1174
= 66.053m/s

The correct answer is<span> measure the distance to a star.
It is</span> the semi-angle of inclination between two sight-lines to the star, as observed when the Earth is on opposite sides of the Sun in its orbit. This is used to measure the distance to closer stars.
False. Gravity was always here but no one really thought about it until Isaac Newton did.
The volume that will be occupied by a gas containing 6.02 x
1023 atoms at STP is 22.4L.
To add, <span>Standard conditions for
temperature and pressure (STP)</span> <span>are </span>standard<span> <span>sets of
conditions for experimental measurements to be established to allow comparisons
to be made between different sets of data.</span></span>
