Answer:
.5m per second to the west
Explanation:
distance divided by time
Answer: (A) 1.5 m
Explanation:
This situation is due to Refraction, a phenomenon in which a wave (the light in this case) bends or changes its direction when passing through a medium with an index of refraction different from the other medium.
In this context, the index of refraction is a number that describes how fast light propagates through a medium or material.
In addition, we have the following equation that states a relationship between the apparent depth and the actual depth :
(1)
Where:
is the air's index of refraction
water's index of refraction.
is the actual depth of water
Now. when is smaller than the apparent depth is smaller than the actual depth. And, when is greater than the apparent depth is greater than the actual depth.
Let's prove it:
(2)
Finally we find the apparent depth of water, which is smaller than the actual depth:
Answer:
the current in the wire is 0.008333333 A
Explanation:
The computation of the current in the wire is as follows;
Current in the wire is
= Total charge ÷ cross sectional area of the wire
= 7.5 × 10^-3C ÷ 0.9s
= 0.008333333 A
Hence, the current in the wire is 0.008333333 A
We simply applied the above formula so that the correct current of the wire could come
And, the same is considerd and relevant too
The acceleration of gravity on Earth is 9.8 m/s² .
After falling for 5 seconds, any falling object is falling (9.8 x 5) = 49 m/s
faster than it was when it was released. Doesn't matter whether it was
dropped, thrown down, or thrown up.
Since the rug was just dropped, its initial speed was zero.
After five seconds, it is moving downward at 49 m/s .
