Answer:
1.425 atm
Explanation:
Gauge pressure, P1' = 2.20 x 10^5 N/m^2 = 2.178 atm
Absolute pressure P1 = P1' + Po
where, Po be the atmospheric pressure
P1 = 2.178 + 1 = 3.178 atm
T1 = 35 degree C = 35 + 273 = 308 k
T2 = - 38 degree c = - 38 + 273 = 235 k
let final absolute pressure is P2. Use
P1 / T1 = P2 / T2
3.178 / 308 = P2 / 235
P2 = 2.425 atm
So, the final gauge pressure = 2.425 - 1 = 1.425 atm
You would weigh 58.967 kilograms
Bigger change in velocity because the object is lighter than the object with more mass so it would move further (sorry it’s not a great explanation)
Answer:
a. is the time after which the two stone hit the water surface.
b.
c. &
Explanation:
Given:
- height of the cliff,
- time gap between the projection of stones,
- initial velocity of first stone,
Here positive sign means that the stone is thrown vertically downward in the direction of gravity.
a.
Using equation of motion:
is the time after which the two stone hit the water surface.
b.
using the equation of motion for second stone:
c.
Final velocity of the stone at the instant of touching the water surface:
&
