R = 18 ohms
Explanation:
Given:
V = 36 volts
I = 2.0 A
R = ?
Use Ohm's law to solve for the resistance:
V = IR
or
R = V/I
= (36 volts)/(2.0 A)
= 18 ohms
Answer:
Explanation:
As the pendulum reached to the lowest position then we will have
now when it will reach to the height of the peg then its speed is given as
so we will have
also we know that
now we have speed of the pendulum when it reach the same height is given as
Now the tension in the string is given as
Answer:
Transverse motion does not produced a doppler effect for a star. As, the doppler effect are occurred when the object are emitting light either in the direction towards the observer or moving away. The various astronomical objects are moving and the observer observed the blue wavelength of the light.
Doppler effect in the star is the process when the observer moves towards the star then it seems like the star move towards the observer.
Answer:
d. the voltage difference between the ends of each resistor is the same.
Explanation:
A resistor is a circuit component that offers opposition to the flow of current. Resistors may be connected in series or in parallel.
Resistors in parallel are connected at common junctions. The potential difference (voltage difference between the ends of each resistor) is the same for each resistor in a parallel connection while the current across each resistor is different.
