Answer:
by using p = mv equation we can find v,
6 = 1.3 v
4.615 = v
Answer:
The magnitude of the torque about the origin is 108 N-m.
Explanation:
Given that,
Mass of the stone, m = 2 kg
Length of the string, l = 0.5 m
Angular velocity of the stone,
The circle is parallel to the xy plane and is centered on the z axis, 0.75 m from the origin, r = 0.75 m
Firstly it is required to find the centripetal force acting on the stone. It is given by :
F = 144 N
Now the magnitude of the torque about the origin is given by :
So, the magnitude of the torque about the origin is 108 N-m. Hence, this is the required solution.
First of all, we need to convert the energy produced from kilojoules to calories. 1 kJ corresponds to 239.1 cal, therefore:
And so now we can calculate the energy value of the oil:
Heat is transferred from hot temperatures to cold temperatures. The temperature of wet clothes is generally lower than the temperatures of our bodies, and so our body temperature lowers because of this hot to cold heat flow.
Explanation:
F = Gm1m2/r^2
