Answer:
1.65 atm
Explanation:
Applying,
PV = nRT....................... Equation 1
Where P = Pressure, V = Volume, n = number of moles, R = malar gas constant, T = Temperature.
Make P the subject of the equation
P = nRT/V..................... Equation 2
From the question,
Given: n = 3.27 moles, V = 50.0 L, T = 35 °C = (273+35) = 308K
Constant: R = 0.082L.atm/K.mol
Substitute these values into equation 2
P = 3.27(0.082)(308)/(50)
P = 1.65 atm
F = m · a
In order to accelerate 82 kg upward at the rate of 3.2 m/s², a NET upward force of (82kg · 3.2m/s²) = 262.4 Newtons is required.
But if the object is on or near the surface of the Earth, then there's a downward force of (82kg · 9.8m/s²) = 803.6 N already acting on it because of gravity.
So you need to apply (803.6N + 262.4N) = <em>1,066 Newtons UPward</em>, in order to cancel its own weight and accelerate it upward at that rate.
Answer:
c
Explanation:
kinetic energy is energy an object has due to its movement. for instance, if someone was riding down a hill, when the motion of the bike begins to decrease so does the kinetic energy
Answer:
Double helix
Explanation:
The Double helix is a DNA molecule. The two strands around the Double Helix is called the twisted ladder.
