Answer:
mechanical thermal chemical
Explanation: because you use mechanical energy to turn it on
<h2>
Answer: joules</h2>
Explanation:
From the first law of thermodynamics,
Δ=Δ+
Where is the heat given to the gas,
is the internal energy of the gas,
is the workdone by the gas.
When pressure is constant,
When pressure is constant,Δ
Where is pressure and is the volume of the gas.
Given
Δ
So,
Given that Δ
So,Δ
Answer:
1 km / 15min
Explanation:
The average speed is calculated by simply doing space divided by time so:
2km / 30min that becomes 1km / 15min
Have a good day.
A change in velocity, A change in direction, or a change in both velocity and direction.
The answer would be C) which is 15+8W
where W represents week, so since you already had fifteen dolor where 8 is the value you save each week.
