Answer:
0.34 x 10^-3 m^3
Explanation:
P1 = 6 x 10^5 N/m^2
T1 = 10 degree C = 10 + 273 = 283 K
T2 = 35 degree c = 35 + 273 = 308 K
Pressure remains constant , P2 = P1
P1 V1 = R T1
V1 = (8.314 x 283) / (6 x 10^5) = 3.92 x 10^-3 m^3
Now, let the Volume is V2
P1 V2 = R T2
V2 = (8.314 x 308) / (6 x 10^5) = 4.26 x 10^-3 m^3
Change in volume, v = V2 - V1 = (4.26 - 3.92) x 10^-3 = 0.34 x 10^-3 m^3
The answer is c. Continuous direct
Explanation:
a) glowing embers in a campfire : It is a non mechanical conversion
(b) a strong wind: Kinetic or mechanical
(c) a swinging pendulum: A combination of potential and kinetic energy.
(d) a person sitting on a mattress: potential energy or mechanical
(e) a rocket being launched into space
: kinetic and potential.
It would take 5.0 s for a racehorse to accelerate from rest to a speed of 15 m/s with an acceleration of 3.0 m/s.
Take 15 / 3.0 to get your answer of D. 5.0 s
Hope that helps u out!
Work = force × distance, assuming that the force is parallel to displacement.
