Answer:
Explanation:
The equation that relates heat Q with the temperature change 
of a substance of mass <em>m </em>and specific heat <em>c </em>is 
.
We want to calculate the final temperature <em>T, </em>so we have:
Which for our values means (in this case we do not need to convert the mass to Kg since <em>c</em> is given in g also and they cancel out, but we add 
to our temperature in 
to have it in 
as it must be):
Answer:
The study of matter and energy, and the relationship between matter and energy
Explanation:
Physical science is natural science studies( in chemistry, geology, physics,astronomy) that focus on non-living materials and natural forces.The non-living systems are mainly the inorganic world.Here the properties of matter and energy in non-living forms are investigated with their connection with nature.
Answer:C
Explanation:
For every action or force there is an equal and opposite reaction or force
So the force on the bat is the same as the force on the ball but in opposite directions
Now the ball will fly farther but that is a different law
Answer:
The answer is C. Kinetic energy
Explanation:
Generators don't actually create electricity. Instead, they convert mechanical or chemical energy into electrical energy. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit.
In navigation bearing refers to : 1. the direction of motion itself; 2. the direction of a distant object relative to the current course 3.the angle away from North of a distant point as observed at the current point.
There is a thing called absolute bearing, and it refers to the angle between the magnetic North/true North and an object. (e.g. an object of 0 degrees would be dead ahead, whereas and object of 180 degrees would be behind you)
