Answer:
1026 N
Explanation:
Force on a moving charge in a magnetic field is given by
F= qvB Sinθ
F = 2 x 5 x 10^6 x 3 x 10-4 x Sin (20)
F = 1026 N
Answer:
yes
Explanation:
because when you shot the ball your applying force to it
Answer: Option (b) is correct.
Explanation:
Since we know that,
P = VI
where;
P = power
V= Voltage
I = Current
Since it's given that,
P = 600W
I = 2.5 A
equating these values in the above equation, we get;
<em>V =
</em>
<em>V = 240 V</em>
Answer:
The displacement was 320 meters.
Explanation:
Assuming projectile motion and zero initial speed (i.e., the object was dropped, not thrown down), you can calculate the displacement using the kinematic equation:

The displacement was 320 meters.
<h3><u>Answer;</u></h3>
= 20.436 seconds
<h3><u>Explanation;</u></h3>
Speed = Distance × time
Therefore;
Time = Distance/speed
Distance = 7.50 m, speed = 0.367 m/s
Time = 7.50/0.367
<u>= 20.436 seconds </u>
