Explanation:V.R of a lever is 3 means effort distance of the lever is 3 times more than the effort distance of the load. ... Efficiency of a lever is 60% means 40% of the energy is wasted due to friction as no machine is Friction less.
Answer:
gravity is changed by a factor of 10/16
Explanation:
gravitational force = m1 m2 G / r^2 now change the m1 and r
= 10 m1 m2 G/ (4 r)^2
= 10 /16 m1 m2 G / r^2
10 /16 the earth's gravity
Answer:
-88 °C
Explanation:
Charles' law is derived from the ideal gas law. The ideal gas law says:
PV = nRT
If n and P are constant, then we get Charles' law:
V₁ / T₁ = V₂ / T₂
Plugging in values and solving:
(125 L) / (35 + 273 K) = (75 L) / T
T = 185 K
T = -88 °C
