Answer:
Explanation:
Given that,
Speed of the electron, 
Magnetic field, B = 0.20 T
We need to find the magnitude of magnetic force on the electron. The formula for the magnetic force is given by :
Here, 
, q is the charge on electron
So, the magnitude of the magnetic force on the electron is 
. Hence, this is the required solution.
Answer:
answer in the explanation!!
Explanation:
1: light being emitted from a light bulb is called electromagnetic waves ; transverse wave.
2: sound coming from a violin is a mechanical wave ; longitudinal wave.
3: a rock being dropped in a pond is a mechanical wave ; and im pretty sure its longitudinal and/or transverse.
Answer:
789.8 W
Explanation:
mass of the cab = 1400 kg, the counter weight of the elevator = 930 kg
weight of the cab = 1400 × 9.81 where weight = mg and m is mass and g is acceleration due to gravity.
weight of the cab = 13734 N
counter weight of the elevator = 930 × 9.81 = 9123.3 N
the exerted force of the elevator = weight of the cab - counter weight of the elevator = 13734 - 9123.3 = 4610.7 N
Average power by the motor P = F × v = F × distance / time
where v is speed in m/s, and time is in seconds
P = 4610.7 × 37 / ( 3.6 × 60) = 789.80 W
where (3.6 × 60 ) is the time in seconds
The correct symbol is 4He. You may also encounter it displayed as helium-4, He-4.
'Acceleration' is any change in the speed or direction of motion.
Now that we ( I ) have that definition clear, we can look through
the choices:
A). \
B). > No. Neither speed nor direction changed.
C). /
D). Yes. The boy's direction changed.
