Answer:
Explanation:
<u>Speed</u>
The speed is calculated as the ratio of the distance d by the time t:
If we need to calculate the distance, the equation is solved for d:
d=v*t
The speed of light is
It takes t=9.221 seconds for light reflected from the moon Vega to reach planet Xartan.
We can calculate the average distance the light traveled:
Or, in scientific notation:
Are there any options or is it not a multiple choice question.
If two wires run parallel and the current passes through
both wires in the same direction, which happens to the wires?
If two wires run parallel and the current passes through
both wires in the same direction, the wires wires move together because the
current of one wire pulls the other wire closer. The answer is letter C.
Answer:
⇒ 401.6 ± 7.1 ms
⇒ 57.2 ± 1.6 kg
⇒ 8.1 × 107 ± 2.9 × 105 m
⇒ 2.1 ± 8.8 µN
⇒ 294 ± 0.005 cm
Explanation:
As given all equation we do without calculation we will get here round these calculations which is given below as
a) 401.6473 ± 7.0912 ms
⇒ 401.6 ± 7.1 ms
b) 57.212 ± 1.612 kg
⇒ 57.2 ± 1.6 kg
c) 8.12754×107 ± 2.847×105 m
⇒ 8.1 × 107 ± 2.9 × 105 m
d) 2.94 ± 8.803 µN
⇒ 2.1 ± 8.8 µN
e) 294 ± 0.00481 cm
⇒ 294 ± 0.005 cm
