The absolute pressure in the container when the monatomic ideal gas is placed under a piston is 1.17 × 10⁵ pa
<h3>How to calculate pressure?</h3>
The absolute pressure in the container will be:
= Po + mg/A
= 1.013 × 10⁵ + (50 × 9.8)/(π × 0.1²)
= 1.17 × 10⁵ pa
The volume of the gas will be:
= nRT/P
= 2 × 8 × 3.14 × (0 + 273)/(1.17 × 10⁵)
= 0.0388m³
The amount of work done by the gas during its expansion will be:
= 1.17 × 10⁵ × (0.053 - 0.0388)
= 1661J

Explanation:
These eight phases are, in order, new Moon, waxing crescent, first quarter, waxing gibbous, full Moon, waning gibbous, third quarter and waning crescent. The cycle repeats once a month (every 29.5 days).
<span>Selection (b) is the best answer. These are the winds found between the 25-degree north and south latitudes, converging at the doldrums just north of the equator. They have been used for centuries to navigate much more quickly around the oceans.</span>
Answer:
H' = H/4
Explanation:
By applying the law of conservation of energy to this problem, we know that:
Elastic Potential Energy Stored by Spring = Gravitational Potential Energy of ball
(1/2)kx² = mgH
H = (1/2)kx²/mg -------------- equation (1)
where,
H = Height reached by the ball
x = compression of spring
k = stiffness of spring
m = mass of ball
g = acceleration due to gravity
Now, if we make the compression to half of its value:
x' = x/2
then:
H' = (1/2)k(x/2)²/mg
H' = (1/4)(1/2)kx²/mg
using equation (1), we get:
<u>H' = H/4</u>
Answer:
B) 41,335 N
Explanation:
As the elevator moves upward the formula for the calculation of tension in the cable is given by.
T-mg =ma
T=mg+ma
T=3500*9.81+3500*2
=34335+7000
T=41,335 N
