The amount of heat that is required to raise the temperature of a system is calculated by the expression:
Heat required = m Cp ΔT
Heat required = 500 g (1.0 calorie/gram °C) (10.0 <span>°C)
Heat required = 5000 calorie
The correct answer from the choices listed above is the second option.</span>
Since the light travels in the vacuum then its velocity will be C=3*10^8 m/sec.....then you will convert it to secs=28000*365*24*60*60=8.83008*10^11
then v=s/t then s=v*t=(3*10^8)(8.83008*10^11)=2.649024*10^20 meters

We use wool blankets (insulator) to say warm during cold nights in July.
The Moment of Inertia of the Disc is represented by . (Correct answer: A)
Let suppose that the Disk is a Rigid Body whose mass is uniformly distributed. The Moment of Inertia of the element is equal to the Moment of Inertia of the entire Disk minus the Moment of Inertia of the Hole, that is to say:
(1)
Where:
- - Moment of inertia of the Disk.
- - Moment of inertia of the Hole.
Then, this formula is expanded as follows:
(1b)
Dimensionally speaking, Mass is directly proportional to the square of the Radius, then we derive the following expression for the Mass removed by the Hole ():
And the resulting equation is:
The moment of inertia of the Disc is represented by . (Correct answer: A)
