Answer:
The angular momentum is
So, we need to find the moment of inertia of the barbell.
The barbell consist of three parts, two masses of 25 kg and a rod of 15 kg.
The moment of inertia of the barbell can be found by summing the moment of inertia of the rod and two masses.
We need to convert 10 rpm to rad/s.
The angular momentum can now be calculated.
Answer:
Water is not able to be used as a thermometer liquid because of its higher freezing point and lower boiling point than the other liquids in general. If water is used in a thermometer, it will start phase variation at 0∘C and 100∘C. This will not help in measuring temperature, beyond this range.

Answer:
F = 592238.09 N
Explanation:
To find the mean force you first calculate the acceleration by using the following kinematic equation:
you do "a" the subject of the equation and replace the values of the other parameters:
next, the force, by using the second Newton law is:
hence, the force is 592238.09 N
- - - - - - - - - - - - - - - - - - - - - - - - - - -
TRANSLATION:
Para encontrar a força média, primeiro calcule a aceleração usando a seguinte equação cinemática:
você faz "a" o assunto da equação e substitui os valores dos outros parâmetros:
Em seguida, a força, usando a segunda lei de Newton, é:
portanto, a força é 592238.09 N
You have to divide 120/600 which you will get 0.2 hours as your answer.
Hope this helps!
