Explanation:
What is said is that the meter fell d=18.3cm=0.183m under the action of gravity. We can use the formula for accelerated motion:
Since it departed from rest it will mean that:
So our time will be:
Which for our values is:
Answer:
The final temperature of the two objects is the same.
Explanation:
The expression for the heat energy in terms of mass, specific heat and the change in the temperature is as follows:
Here, Q is the heat energy, m is the mass of the object, c is the specific heat and are the final temperature and initial temperature.
According to the given question, Two objects of the same mass, but made of different materials, are initially at the same temperature. Equal amounts of heat are added to each object.
............(1)
.............(2)
From (1) and (2),
Therefore, the final temperature of the two objects is the same.
Answer:
Energy, E = 178.36 J
Explanation:
It is given that,
Mass 1,
Mass 2,
Mass 3,
Height from which they are dropped, h = 1.3 m
Let m is the energy used by the clock in a week. The energy is equal to the gravitational potential energy. It is given by :
E = 178.36 J
So, the energy used by the clock in a week is 178.36 Joules. Hence, this is the required solution.
