Answer:
200 J
Explanation:
Work = Force × Distance
Work = (20 N)(10 m) = 200 N·m = 200 J
200 joules of work are done by a force of 20 N over a distance of 10 m.
Increasing temperature increasing the amount of energy in the system causing the average speed to increase.
think giving a 3 yr old a 6 pack of Reese's Cups. that os what would happen of you increase the temperature of a system
Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that the acceleration due to gravity is given as



now we know that



now we have


Part b)
As we know that the escape speed is given as




Answer:
The extension is directly proportional to the force applied.
ex: if the force is doubled, the extension doubles. This works until the limit of proportionality is exceeded.

Explanation:
Answer:
v = 27.456 m/s
Explanation:
The support pressure needed of the water in the straw can be calculated by the formula
Given that,
P = r*g*h
= 1000*9.8*0.05 Pa.= 490 Pa
This pressure is compensated by 0.5*r*v^2 of the air,
Hence,
0.5*1.3*v^2 = 490
velocity of air blown into the straw =
v = 27.456 m/s
