Answer:
final temperature of slug of gold is 37°C
final temperature of slug of manganese is 28.56°C
Explanation:
Hello! To solve this problem we must take into account the concept of heat capacity, this is defined as the ratio between energy and temperature rise.
In other words it is the amount of energy that is required to increase a temperature degree.
Taking into account the above we infer the following equation
where
C=heat capacity
Answer:
- The gravity does a work of - 117.6 Joules.
- The tension does not do work as the force is perpendicular to the direction of motion at any point in the trajectory.
Explanation:
The work done by the gravity simply is the difference in gravitational potential energy multiplied by -1:
where m is the mass of the ball, g is the acceleration due to gravity, is the final height and is the initial height.
So, if the radius is 2.00 m, then the difference of height will be 4 meters:
As the tension is perpendicular to the velocity of the ball, the force is always perpendicular to the direction of motion. So, the differential of work will be:
Increased by a factor of 4
