Answer:
P_2 = 62.69 psi
Explanation:
given,
P₁ = 70 psia T₁ = 55° F = (55 + 459.67) R
P₂ = ? T₂ = 115° F = (115 + 459.67) R
we know,
p = ρ RT
ρ is the density which is constant
R is also constant
now,
P_2 = 62.69 psi
Hence, the increase in Pressure is equal to P_2 = 62.69 psi
Answer:
B. At stage B, because the elastic is completely strecthed.
Explanation:
Try pulling a rubber band or something stretchable and take a piece of small paper (just enough to fit in the rubber band). now try to pull the rubber band into 3 levels.
1st level - pull the rubber band with a short force and see if the paper will travel farther.
2nd level - now pull the rubber band with a medium force and see if the paper will be much farther compared to the (1st level)
3rd level - pull the rubber band with full force and see if the paper is much farther compared to the (2nd level).

Answer:
T = 5516.63 seconds
Explanation:
Given that,
The International Space Station is orbiting at an altitude of about 370 km above the earth's surface.
Mass of the Earth,
Radius of Earth,
We need to find the period of the International Space Station's orbit. It is a case of Kepler's third law. Its mathematical form is given by :
R = r + h
So, the period of the International Space Station's orbit is 5516.63 seconds.
Answer is: <span>canoe's kinetic energy is 136 J.
</span>m(canoe) = 17 kg.
v (speedcanoe) = 4 m/s.
E(canoe's kinetic energy) = ?
E = 1/2 · m(canoe) · v²(canoe).
E = 0,5 · 17 kg · 16 m²/s².
E = 136 J.
<span>The kinetic energy of a non rotating object of </span>mass m<span> traveling at a </span>speed v. <span>The standard unit of kinetic energy is the </span>joule.
