Answer:
Velocity of the particle at time t = a
Velocity of the particle at time t = 1
Velocity of the particle at time t = 2
Velocity of the particle at time t = 3
Explanation:
Displacement,
Velocity is given by
Velocity of the particle at time t = a
Velocity of the particle at time t = 1
Velocity of the particle at time t = 2
Velocity of the particle at time t = 3
mass and velocity
Explanation:
Momentum depends on two important factors which are the mass and velocity of a body.
Momentum = mass x velocity
- Momentum can be defined as the product of mass and velocity.
- It is a vector quantity that has both magnitude and directions.
- Momentum is a very important quantity in physics as it shows the impact of a force on another.
- The unit is Kgm/s²
- It is the same as impulse.

(NH4)2CO3(s) ⇄ 2NH3(g) + CO2(g) + H2O (g)
The effect that adding water (H2O) have in reaction above is that The concentration of the product would decrease, and the concentration of reactant would increase. (answer C)
<u><em>Explanation</em></u>
- If the concentration of one substance is changed, the equilibrium shift to minimize the effect of that change.
- H2O in reaction above is a product.
- Increase of water (H2O) concentration will led to the shift of equilibrium to the left ( reactant side) .The concentration of reactant increase as that of product decrease.
The strain energy stored in a linear spring is
SE = (1/2)*k*x²
where
k = the spring constant
x = the extension (or compression) of the spring
Given:
k = 470 N/m
x = 17.0 cm = 0.17 m
Therefore
SE = 0.5*(470 N/m)*(0.17 m)² = 6.7915 J
Answer: 6.8 J (nearest tenth)
