Answer:
C) volts
Explanation:
f = frequency of oscillator = 1 kHz = 1000 Hz
= 12 Volts
L = Inductance of Inductor = 5 mH = 0.005 H
= Inductive reactance
Inductive reactance is given as
=
=
= Capacitive reactance
Capacitive reactance is given as
Impedance of the circuit is given as
Rms Current flowing is given as
A
Rms potential difference across the resistor is given as
volts
Answer:
20x120=2400m equivalent to 2km
15x120 =1800 m = 1.8km
2km +1.8 km = 3.8 km
Answer:
13 m/s
Explanation:
I assume we are ignoring friction.
The boy's PE will all be converted to KE at the bottom of the hill.
to find PE = mgh we need to know h
h = 50 sin 10 = 8.68 meters
then: PE = 20 * 9.81 * 8.68 =<u> 1703.49</u> j
KE = 1/2 m v^2 = <u>1703 .49</u>
v = 13 m/s
Answer:
The red ball has greater kinetic energy because it is moving at the same speed as the yellow ball, which is lighter than the red ball.
Explanation:
Formula for kinetic energy: 1/2mv²
Yellow ball:
= 1/2(2)(3)²
=1/2(2)(9)
= 9J
Red ball:
= 1/2(3)(3)²
=1/2(3)(9)
= 13.5J
Answer:
Correct answer: F = 0 N
Explanation:
All three elementary charges are in the same straight line or direction.
Since the electron and proton are opposite charged, their force is attractive and directed toward the electron.
The forces are of the same intensity-magnitude and opposite directions and are canceled, so the resultant- net force by which the electrons act on the proton is zero.
