Work = force x distance. So the answer would be 200x50=10000 joules
The principle of moments states that for a system at equilibrium the clockwise moments is equal to the anticlockwise moments.
Moments is given by force × perpendicular distance
Moments one one side of the seesaw will be 340Nm and on the other will be 500Nm, for balanced or equilibrium to be achieved the two moments should be equal.
Difference is 160 Nm, thus with a child 10 kg to balance the system, then,
Distance will be 16 nm/ 100N = 1.6 m
Threfore, a child of 10 kg should sit at a distance of 1.6m from the pivot on the side with 17 kg child for the system to balance.
Answer:
Second law of motion.
Explanation:
According to second law of motion Force is equals to mass multiplied by acceleration.
Here, Mass is given which is 10 kilograms.
Force is given which is 100 Newton.
So, by putting the values of mass and force in the formula of second law of motion we will get the value of acceleration which is 10 meters per second per second.

Explanation:
Answer:
Explanation:
Initial volume v₁ =46 x 10⁻⁶ m³
Initial temperature T₁ = 438.28 + 273 = 711.28 K
Initial pressure P₁ = nRT₁ / v₁
= 30.4 x8.3 x 711.28 / (46 x 10⁻⁶ )
= 3901.5 x 10⁶ Pa
Final temperature T₂ = 824 + 273 = 1097 K
Final volume V₂ =?
For isobaric process
v₁ / T₁ = V₂ / T₂
V₂ = V₁ X T₂ /T₁
= 46 X 10⁻⁶ X 1097/ 711.28
= 70.94 X 10⁻⁶ m³ = 70.94 cm³
b ) For isothermal change
P₁ V₁ = P₂V₂
P₂ = P₁V₁ / V₂
= 3901.5 X 10⁶ X 46 / 24.3
7385.55 X 10⁶ Pa.
