F = G m1*m2 / r^2 => [G] = [F]*[r]^2 /([m1]*[m2]) = N * m^2 / kg^2
That is one answer.
Also, you can use the fact that N = kg*m/s^2
[G] = kg * m / s^2 * m^2 / kg^2 = m^3 /(s^2 * kg)
Answer:
TRUE
Explanation:
The answer is true.
Balance forces acting on a body will not change the motion of the body because the body experiences no net resultant force in one direction. When any body experiences equal forces with opposite directions, the net force or the resultant force experience by the body is zero.
In case of an unbalanced forces, there is a net force acting in one direction and so it causes the body to change in its state of motion in the direction of the net force.
Answer:
(a) Amplitude=0.0760 m
(b) Speed=0.337 m/s
Explanation:
(a) For amplitude
We can use the mentioned description of the motion and the energy conservation principle to find amplitude of oscillatory motion
(b) For Speed
Again we can use the mentioned description of the motion and the energy conservation principle to find amplitude of oscillatory motion
The temp would affect the length of the wire
the length would affect how much support there is as well as the diameter of the wire
Answer:
(a) 1.35 x 10^6 Joule
(b) 321.45 Kcal
Explanation:
Energy consumed in 1 hour = 270 kJ
So, Energy consumed in 5 hour = 270 x 5 = 1350 kJ
(a) Energy in joules = 1350 x 1000 J = 1.35 x 10^6 J
(b) 4.2 Joule = 1 calorie
So, 1.35 x 10^6 Joule = 1.35 x 10^6 / 4.2 = 0.32 x 10^6 Calorie
= 0.32 x 1000 Kcal = 321.45 Kcal
