All of the above .........
Answer:
Newton's second law of motion states that the acceleration ( a) experienced by an object is directly proportional to the net force ( Fnet) experienced by the object and inversely proportional to the mass of the object. In equation form, it could be said that a = Fnet/m. The net force is the vector sum of all the individual force values.
Explanation:
The statement (C) <span>The current carrying loop is able to turn because the magnetic force is always parallel to it.
In an electric motor the current do not reduce at any point. So, the (A) is also not correct.
The correct statement about an electric motor is (B),
</span><span>The current carrying loop is able to turn because the magnetic force is always at a right angle to it.</span>
Answer:
925.04 J/s
Explanation:
T = 80 C = 80 + 273 = 353 K
To = 20 c = 20 + 273 = 293 K
A = 2 m^2
Use the formula for Stefan's law
Energy radiated per second


E = 925.04 J/s
Answer:
10.337m/s2
Explanation:
F=ma
a=F/m
a = 92 / 8.9 = 10.337m/s2
