Answer:
- <u> From your frame of reference, the speed of your friend is zero.</u>
Explanation:
The<em> speed</em> from a <em>frame of reference</em> is the magnitude of the change of the position per unit of time in that frame of reference.
When it is said that, to a <em>stationary observer</em> you have a <em>speed of 9m/s</em>, it means that the observer "measures" tha your position, in a moment, changes 9 m per second.
Since both you and your friend are sit still on the same spinning merry-go-round, neither of you will change positions with respect to the other, meaning that you will perceive that your friend will not move, from your frame of reference. That is, if you are isolated from the rest of the universe, and the merry-go-round continues spining uniformly, you cannot detect any movement of your friend, which means that from your frame of reference, the speed of your friend is zero.
As per the question,the current amplitude is given as i= -2.7 micro ampere
i.e -2.7 ×
as per the question the time is given as t=1.15s
we know that 
hence q=i×t
hence the total charge passing through this point is given as
q= -2.7×× 1.15
= -3.105×
we know that q=ne where n is the number of electrons and e is the charge of electron
we have e= -1.602×
coulomb
hence number of electrons n=
= 3.105××
=1.93820×
Answer:
i have no idea
Explanation:
it could be B. but i dont belive in myself sooooooooooo.....ehhhh yeah
The force exerted by gravity is:
F = m g
F = 3300 kg * 9.8 m/s^2
F = 32,430 N
The force exerted due to the inclined plane is:
F tractor = 32,430 N * sin 14
<span>F tractor = 7,823.75 N (answer)</span>
