The current in the circuit drops and reduces, because of the higher voltage.
Because of the higher potential difference, the current in the circuit reduces as well.
c. II and III only (the object has 0 acceleration and the object has constant velocity.)
Why?
Let's discard each of the given options to find the correct one(s).
<h3>
- There are no forces acting on the object:</h3>
False, if an object has a constant speed, it does not mean that there are no forces acting on it, in fact, there will be always acting forces, like frictional force, gravity force, air resistance, and others.
<h3>
- The object has a 0 acceleration:</h3>
True, in an object is moving at constant speed, it means that there is no acceleration, the speed will be the same all the time during motion.
<h3>
- The object has constant velocity:</h3>
True, <u>if an object is moving in a straight line at constant speed</u> the velocity will be also constant. The velocity of an object is referring to its speed and its direction, if the object is moving in a straight line, the direction will be the same, so, if the speed is constant, the velocity will be also constant.
Have a nice day!
Answer:
a) Mechanical equivalence of heat
Explanation:
heat is an energy that is transferred from one body to another because of a difference in temperature and in any system of physical units, the number of units of work or energy equal to one unit of heat.
I believe the correct answer is atmosphere (D).
