Answer:
The maximum no. of electrons-
Solution:
As per the question:
Maximum rate of transfer of charge, I = 1.0 C/s
Time, t = 1.0 h = 3600 s
Rate of transfer of charge is current, I
Also,
Q = ne
where
n = no. of electrons
Q = charge in coulomb
I = current
Thus
Q = It
Thus the charge flow in 1. 0 h:
Maximum number of electrons, n is given by:
where
e = charge on an electron =
Thus
Go through the intersection without stopping is the appropriate action to be taken in a case where the light at an intersection is red and a police officer directs you to go through it.
<h3>What is Traffic light?</h3>
This is also referred to as stoplights and is present in the intersection of roads etc so as to help control traffic and prevent the occurrences of accidents on the road.
In cases where there is no officer, the traffic light must be obeyed but where the officer is present then his authority overrules and must be obeyed as he is in the best position to know the reason why the traffic light should be ignored in this type of scenario.
This is therefore the reason why the individual should go through the intersection without stopping.

Answer:2.617s
Explanation:note, a=g=acceleration due to gravity=9.81m/s2. It is negative when the ball is travelling upwards against gravity
The initial volume of the gas is
while its final volume is
so its variation of volume is
The pressure is constant, and it is
Therefore the work done by the gas is
where the negative sign means the work is done by the surrounding on the gas.
The heat energy given to the gas is
And the change in internal energy of the gas can be found by using the first law of thermodynamics:
where the positive sign means the internal energy of the gas has increased.
Answer:
<h2><em>
0.165Tesla</em></h2>
Explanation:
The Force experienced by the wire in the uniform magnetic field is expressed as F = BILsin∝ where;
B is the magnetic field (in Tesla)
I is the current (in amperes)
L is the length of the wire (in meters)
∝ is the angle that the conductor makes with the magnetic field.
Given parameters
L = 0.56 m
I = 2.6A
F = 0.24N
∝ = 90°
Required
magnitude of the magnetic field (B)
Substituting the given values into the formula given above we will have;
F = BILsin∝
0.24 = B * 2.6 * 0.56 sin90°
0.24 = B * 2.6 * 0.56 (1)
0.24 = 1.456B
1.456B = 0.24
Dividing both sides by 1.456 will give;
1.456B/1.456 = 0.24/1.456
B ≈ 0.165Tesla
<em>Hence the magnitude of the magnetic field is approximately 0.165Tesla</em>
