Answer:
The number of electrons passes through the circuit if it detects a signal which persists for 1.0 microseconds is 
.
Explanation:
A circuit in a radio receiver requires a current of at least 1.0 microamp in order to detect a signal. It is required to find the number of electrons passing through the circuit if it detects a signal which persists for 1.0 microseconds.
It is known that the total amount of charge passing through a circuit is calculated as, Q=It.
Where I is the amount of current passing through a time of t.
For this problem, I=1.0 microamp, and t=1.0 microseconds. Therefore the amount of charge is,
The amount of charge in one electron is 
, therefore the number of electrons passing through the circuit while carrying 
amount of charge is,

<span>Answer:
I'm pretty sure the SA / V ratio would get smaller. Assume that the cell is more or less spherical. SA = 4(pi)r^2, while V = (3/4)(pi)r^3. The ratio = (4(pi)r^2)/((3/4)(pi)r^3), which can be simplified to 3/r. Thus, the larger r gets, the smaller the ratio becomes.</span>

Explanation:
Maximum height of the pumpkin, 
Initial speed, v = 22 m/s
We need to find the angle with which the pumpkin is fired. the maximum height of the projectile is given by :
On rearranging the above equation, to find the angle as :
So, the angle with which the pumpkin is fired is 39.49 degrees. Hence, this is the required solution.
