True.
I think that’s the answer.
<span>Glass is transparent meaning light passes through it and therefore you can see through it, but some light reflects back and if the surface is very smooth as glass often is then the light reflected back can be seen as a reflected image.</span>
Q = heat energy , m=mass , c=specific heat , delta T= change in temperature
as you know heat is a form of energy which is <em>usually</em> measured in Joules according to the SI. and also we usually use kilograms for mass.
so you need to know the mass, specific heat, and change in temperature in order to find out the heat energy :)
Answer:
in salt water
Explanation:
The buoyant force acting on a body depends on the volume of body immersed, density of liquid in which the body is immersed and acceleration due to gravity.
Buoyant force = Volume immersed x density of liquid x g
As the density of salt water is more than the fresh water so the buoyant force acting on the boat in salt water is more than the fresh water.
