Answer:
The temperature of an object increases when the molecules that make up that object move faster. Thermal energy is energy possessed by an object or system due to the movement of particles within the object or the system.
Answer:
the formula of mechanical advantage is
MA = load / effort
VR = effort distance / load distance

Answer:
48.6°
Explanation:
The forward force, F equals the component of the weight along the slope.
So mgsinθ = ma where a = acceleration and θ = angle between the slope and the horizontal.
So a = gsinθ
Since we are given that a = 75%g = 0.75g,
0.75g = gsinθ
sinθ = 0.75
θ = sin⁻¹(0.75)
= 48.6°
Answer:
i believe B, my apologies if wrong, let me know if it was wrong so I can correct myself
Explanation:
Option (d) is correct.
Distance is the total path length covered by the object.
so, for distance, we add all the path lengths
Here the total distance =7+5+2 =14 km
