Which temperature change would cause the pressure of a gas to double if its volume remains the same? A. Increasing from 200 K to 400 K
B. Decreasing from 400°C to 200°C
C. Increasing from 20°C to 200°C
D. Increasing from 20°C to 40°C

a.

Explanation:

because it makes more i think idk hehe sorry this isn't a real answer  by

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

d.) circle motion requires a force to give it a centripetal acceleration.
