Answer:
Explanation:
Given that:
Charge Q = 10400 C
current I = 0.530 mA
From our previous knowledge, we know that charge Q can be expressed as:
Q = I×t
where
I = current and t = time
∴
replacing our values
10400 = (0.530×10⁻³) t
t = 10400/(0.530×10⁻³)
t = 19622641.51 seconds
However, the required flow of electrons per seconds can be calculated by using the formula:
number of electrons/second = current (I)/ charge on electron
= (0.530×10⁻³)/(1.6×10⁻¹⁹)
= 3.3125×10¹⁵ electrons
Answer:
No number answer; don't want to pull out a calculator lol
Explanation:
Capacitors are added in parallel; opposite of resistors.
So for 9, add 10 and 2.5 then do ((1/12.5)+(1/.3))^-1.
For 10, add 0.75 and 15 first, then the rest is the same idea as 9.
Answer:
a constabt force that acts on object that rub together
Explanation:
It is because Friction is the rubbing of one body against another body
In order to find the our own velocity with respect to land,we need to apply the theory of relative velocity.
Now consider the velocity of the ship traveling towards the north with respect to land as A.Consider our own velocity headed northwards as B.
The relative velocity is the velocity that the body A would appear to an observer on the body B and vice versa.
In this case the relative velocity would be arrived by summing up our velocity with the velocity of the ship as the object (I) is travelling in the ship.
Relative velocity = Velocity of Body A+ Velocity of Body B.
Velocity of the ship traveling towards the north with respect to land(A)= 13.0m/s. (Given)
Our own velocity headed northwards(B)= 2.8 m/s.
Relative velocity = Velocity of Body A+ Velocity of Body B.
Relative velocity= 13.0 + 2.8 = 15.8m/s.
Thus our own velocity with respect to the land is 15.8 m/s.
