The trampoline's elastic potential energy is transformed into kinetic energy when it returns to its original position.
The ball's gravitational potential energy become kinetic energy when it drops. Pls give brainliest

there in 2.3 grams of NH
SO.?
Answer:
1.69 x 10^22
A positive change atom of hydrogen-ion. A normal hydrogen atomic nucleus
Answer: 139.57 L
Explanation:
Through Charles' Law, we know that volume and temperature have a proportional relationship meaning that if we increase the temperature, the volume will also increase. We can use the following formula: (V1/T1) = (V2/T2)
The equation of Charle's law requires temperature to be in ubnits of Kelvin.
So to find the new temp in kelvin, we use T + 273 so the two temps are 523 and 1123. Now we can plug in our values into the formula
(65/523) = (x/1123)
x= 139.57 L
Answer:
173.8g
Explanation:
STP means standard temperature and pressure
The temperature there is 273k while the pressure is 1 atm
now we are to use the ideal gas equation to get the number of moles first
Mathematically;
PV = nRT
here P = 1 atm
V = 88.5 L
n = ?
R = molar gas constant = 0.082 L atm mol^-1 K^-1
Now rewriting the equation we can have
n = PV/RT
plugging the values we have
n = (1 * 88.5)/(0.082 * 273)
n = 88.5/22.386
n = 3.95 moles
Now we proceed to get the mass
Mathematically;
mass = no of moles * molar mass
molar mass of carbon iv oxide is 44g/mol
mass = 3.95 * 44 = 173.8 g
