Answer:
mass is lifted 1.8 m. What is the potential energy of the mass 4. A 100 kg
Answer:
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
Explanation:
Answer:
There are equal parts reactants and products.
Explanation:
When a system is in a chemical equilibrium, the rate at which the forward reaction occur is the same as the rate at which the reverse reaction occurs. This system is said to undergo a reversible reaction. The concentration of the reactants and products do not change, i.e are constant.
In a chemical equilibrium, the reaction continues in both directions but at the same rate.
Therefore the statement that is a misconception about a system in chemical equilibrium is 'There are equal parts reactants and products'.
A compound machine uses more than one simple machine to work. The six classic examples of simple machines are: Lever, wheel/axle, pulley, inclined plane, wedge, and a screw.
A ramp is an inclined plane. Therefore, the answer is D. a pair of scissors
