Answer:
19.0 m/s
Explanation:
First of all, we can find the acceleration of the object by using Newton's second law:
where
F = 200 N is the net force applied to the object
m = 50.0 kg is the mass of the object
a is the acceleration
Solving for a,
Now we can find the final speed of the object:
where
u = 3.0 m/s is the initial speed
a = 4.0 m/s^2 is the acceleration
t = 4.0 s is the time
Substituting,
Answer:
Average power of this circuit, P = 44.64 watts
Explanation:
It is given that,
The power factor of RC circuit,
The rms value of the AC voltage,
Impedance of the circuit, Z = 200 ohms
The average power of this circuit is given by the formula as follows :
P = 44.64 watts
So, the average power of this circuit is 44.64 watts. Hence, this is the required solution.
We calculate as follows:
d = 0.025 m
<span>Δx = 0.31 m
</span>
<span>W = pΔV = p(πd²)(Δx/4) </span>
<span>W = 2.4x10⁵(3.14x0.025²)(0.31/4) =36.5 J
</span>
<span>F = W / Δx = 36.5 / 0.31 = 117.8 N
</span>
Hope this answers the question. Have a nice day.
Answer:
C
Explanation:
velocity = displacement (m) / change of time (s)
velocity = (400 + 300) / (100 + 400)
velocity = 1.4 m/s
