Answer:
Passive solar heating uses building design to utilize sunlight, while active solar heating uses technology.
Explanation:
lol
It should be, I mean it will be more organized for them
Answer:
Cause and effect, problem and solution, order of importance, comparison and contrast.
Explanation:
Assuming that the stone is thrown vertically... let's say it's a 1 kg stone.It doesn't matter if it's thrown upwards or downwards as (assuming no air friction) it will pass the original throwing point with the same downwards velocity as it had upwards, 3 seconds previously. So it starts with 1/2 m v^2 = 0.5 * 1 * 15^2 = 112.5 J of keThen k.e. gained = gpe lostk.e. gained = m g h = 1 * 10 * 50 = 500 J of Ke gainedso the final (total) ke is 612.5 J which = 1/2 m v^2 = 0.5 v^2 here
so 0.5 v^2 = 612.5so v^2 = 1225so v = 35 m/s
Answer : The temperature will be, 969.66 K
Explanation :
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.
or,
where,
= initial pressure of gas = 758 torr
= final pressure of gas = 2500 torr
= initial temperature of gas =
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
Thus, the temperature will be 969.66 K
