2.) Projectile motion is caused by____________.
d.) the downward force of gravity and an initial forward velocity.
Vf=vi+at
Vf= (50m/s)+ (5m/s2)(3s)
Vf=65m/s
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.
When a torque is applied to an object it rotates with acceleration which is inversely proportional to its moment of inertia. The moment of inertia is a rotational mass and the torque is a rotational force
