I think the answer is C. Remaining constant
I believe the answers you're looking for is effectively but not efficiently. The reason its these choices is because although you finished the job, it was not done in the best way possible. So it was effective, but not efficient.
Answer:
Conduction is fastest in solid
Explanation:
A basic property of conduction is that for heat to transfer there must be contact. From kinetic theory, configuration of solid is such that the molecules are held together and they move or vibrate about their mean position. Because of this arrangement heat transfer by conduction is faster in solid that any other state of matter
Answer:
Time elapsed
Explanation:
Acceleration is a vector quantity. It is defined as:

where
v is the final velocity
u is the initial velocity
t is the time elapsed
Acceleration is measured in meters per second squared (m/s^2). It must be noticed that acceleration is a vector, so it also has a direction. In particular:
- when acceleration is negative, it means that the object is slowing down, so acceleration is in opposite direction to the velocity
- when acceleration is positive, it means that the object is speeding up, so acceleration is in the same direction as the velocity
Answer:
A - Watt
Explanation:
Watt is the unit of electrical power in a metric system, expressed in terms of energy per second, equal to the work done at a rate of 1 joule per second is
power formula is P = V × I,
where V is the voltage in a circuit
I is the current flowing through that circuit.
In the SI (metric) system, the units of power are watts.
