<u>Net Force And Acceleration
</u>
The Newton's second law relates the net force applied on an object of mass m and the acceleration it aquires by
The net force is the vector sum of all forces. In this problem, we are not given the magnitude of each force, only their angles. For the sake of solving the problem and giving a good guide on how to proceed with similar problems, we'll assume both forces have equal magnitudes of F=40 N
The components of the first force are
The components of the second force are
The net force is
The magnitude of the net force is
The acceleration has a magnitude of
The direction of the acceleration is the same as the net force:
Answer:
1 is 90, 2 is 200 and 3 is 5
Explanation:
im big brain so i know lol
<span>Basically, the variable n is equal to the amount of P out of the system divided by the about of P into the system

Answer:
The maximum voltage is 41.92 V.
Explanation:
Given that,
Peak voltage = 590 volts
Suppose in an L-R-C series circuit, the resistance is 400 ohms, the inductance is 0.380 Henry, and the capacitance is .
We need to calculate the resonance frequency
Using formula of frequency
Put the value into the formula
We need to calculate the maximum current
Using formula of current
Impedance of the circuit is
At resonance frequency
We need to calculate the maximum voltage
Using ohm's law
Hence, The maximum voltage is 41.92 V.
