Answer:
Parallel
Explanation:
An electric charge in a magnetic field will experience no force if the charge is moving parallel to the field.
WHEN AUTO MOBILE MAKERS SAY THAT THEIR CARS ARE MORE POWERFUL IT MEANS AS IN TORQUE
Answer:
6KW
Explanation:
The computation is shown below:
We know that
Work done= m ×g× h
Here
W= 300×10×10
= 30000 J
= 30 KJ
And
Power= Work done ÷time taken
P = 30000 ÷ 5
= 6000W
= 6KW
The above represent the answer

Explanation:
F=5.6×10^-10N
R=93cm=0.93m
let take m1 and m2 =m²
according to newton's law of universal gravitation
F=m1m2/r²
F=m²/r²
now we have to find masses
F×r²=m²
5.6×10^10N×0.93m=m²
5.208×10^-9=m²
taking square root on b.s
√5.208×10^-9=√m²
so the two masses are m1=7.2×10^-5
and m2=7.2×10^-5
Answer:
0.22
Explanation:
Given that
Radius of turntable, R = 19 cm = 0.19 m
Speed of rotation the turntable, f = 32 rpm = 32/60 = 0.533 rev/sec
from free body diagram and forces resolution, we have
μ(s) * m * g = m * v²/R
μ(s) * g = v²/R
μ(s) = v² / gR, recall, v = wr, so
μ(s) = w²R² / gR
μ(s) = w²R / g, recall again, w = 2πf
μ(s) = (2πf)²R / g, on substituting,
μ(s) = (2 * 3.142 * 0.533)² * 0.19 / 9.8
μ(s) = 3.35² * 0.19 / 9.8
μ(s) = 2.13 / 9.8
μ(s) = 0.22
