Answer:
Time spent by the charge in the magnetic field = 0.008445 s = (8.445 × 10⁻³) s
Explanation:
The force exerted on the charge due to magnetic field = the centripetal force that causes the charge to move in a circular motion.
Force due to magnetic field = qvB sin θ
q = charge on the particle = 8.6 μC
v = velocity of the charge
B = magnetic field strength = 3.2 T
θ = angle between the velocity of the charge and the magnetic field = 90°, sin 90° = 1
F = qvB
Centripetal force responsible for circular motion = mv²/r = mvw
where w = angular velocity.
mvw = qvB
mw = qB
w = (qB/m) = (8.6 × 10⁻⁶ × 3.2)/(7.4 × 10⁻⁸)
w = 3.72 × 10² rad/s
w = 372 rad/s
w = (angular displacement)/time
Time = (angular displacement)/w
Angular displacement = π rads (half of a circle; 2π/2)
Time = (π/372) = 0.008445 s
Answer:
Explanation:
Wall reactions are never constant as the ladder angle decreases from vertical.
I will ASSUME that the MAXIMUM wall reaction is 40 N before slippage occurs.
Let θ be the ladder angle to horizontal
Moments about the ladder foot will sum to zero
40[5sinθ) - 100[(5/2)cosθ = 0
40[5sinθ) = 100[(5/2)cosθ
200sinθ = 250cosθ
sinθ/cosθ = 250/200
tanθ = 1.25
θ = 51.34019174...
θ = 51°

To find speed with distance and time, you need to remember the speed formula:
Speed = distance ÷ time
So we need speed and we have the other two values, we can plug the values in:
Speed = 20 ÷ 2 = 10
The measurement for speed in this case is m/s (metres per second)
<h3>So the answer is 10m/s</h3>

Answer:
t is appropriate to clarify that units such as time and angles the transformation is not in base ten, for example:
60 s = 1 min
60 min = 1 h
24 h = 1 day
Therefore, for this transformation, you must be more careful
the length transformation is base 10
Explanation:
In many exercises the units used are transformed by equations into other units called derivatives, in general the transformation of derived units is the product of the transformation of the constituent units.
In the example of velocity, the derivative unit is m / s, which is why it works in the same way that you transform length and time if in the equation it is multiplying it is multiplied and if it is dividing it is divided.
It is appropriate to clarify that units such as time and angles the transformation is not in base ten, for example:
60 s = 1 min
60 min = 1 h
24 h = 1 day
Therefore, for this transformation, you must be more careful
