Its speed decreases, its wavelength increases, and its frequency Remains the Same.
Answer:
4*9 = 36 m/sec at 9 seconds. The average speed is (0 + 36)/2 = 18 .
Explanation:
Answer:
C. X: Allows current to flow into the commutator
Y: Conducts current to the armature and reverses direction of current
Explanation:
Carbon brush is a motor brush that acts as the conducting block for current between the stator and the rotor of a motor.It is made of carbon blocks.The brush is held in place using a spring that ensures its contact position with the commutator.The commutator prevents the torque on the motor from reversing whenever the coil is rotating in the magnetic field.
A baseball traveling at 100 mph has more kinetic energy than a baseball traveling at 50 mph because the kinetic energy = 1/2 x mass x velocity. Since the baseballs should have the same mass, the velocity is what will determine which ball has more kinetic energy. Since the 100 mph baseball has a higher velocity than the 50 mph baseball, it has more kinetic energy.
This officer would be describing it's "acceleration". When someone is talking about how fast something or someone is going in this or this amount of seconds or minutes, this shows us that this person is reffering to this.
