The electrons are already there. They are freely moving through the conductor.
Answer:
y = 4 Sin (2πt)
Explanation:
Amplitude, A = 4
frequency, f = 1
Wave function is given by
y = A sinωt
where, ω is angular frequency
ω = 2 π f = 2 π x 1 = 2π
So, the desired wave function
y = 4 Sin (2πt)
Answer:
Explanation:
Givens
Vi = 10 m/s
Vf = 40 m/s
a = 3 m/s^2
Formula
a = (vf - vi) /t Substitute the givens into this formuls
Solution
3 = (40 - 10) / t Multiply both sides by t
3*t = t(40 - 10)/t Combine. Cancel t's on the right
3*t = 30 Divide by 3
3t/3 = 30 / 3
Answer: t = 10 seconds.
The formula (ma = F - Fg) is used to determine the net upward force acting on a body.
<h3>
What is net upward force acting on a body?</h3>
The net upward force acting on a body is the resultant or sum of all the upward forces acting on a body at a given time.
ma = F - Fg
where;
- F is the applied force
- Fg is the force of gravity
- ma is the resultant force
Thus, the formula (ma = F - Fg) is used to determine the net upward force acting on a body.
