Answer:
v = 10 m/s
Explanation:
given,
Mass of large fish, M = 5 Kg
speed of swimming, v' = 2 m/s
mass of small fish, m = 1 kg
speed of the fish = v
using conservation of momentum
m v + M v' = M u' + m u
final speed of both the speed is zero.
- 1 x v + 5 x 2 = 0
negative sign is used because small fish is moving in opposite direction.
now,
v = 10 m/s
hence, the speed of the small fish is equal to 10 m/s.
Answer:
a) kinetic energy and gravitational potential energy
Explanation:
The water at the top of the fall possesses kinetic energy because the water is in motion, moving.
The water at the top also possess gravitational potential energy because it is falling under the influence of gravity. It is in a gravitational field.
Answer:
The concentration of acetic acid present in the vinegar is 0.113M
Explanation:
1. As the titration occurs between an acid and a base is called neutralization. The balanced chemical reaction between the acetic acid and the NaOH is:

2. Calculate the moles of NaOH used, taking in account the concentration of NaOH 1.00M:

3. Calculate the number of moles of acetic acid neutralized using stoichiometry:

4. Calculate the concentration of acetic acid present in the vinegar:

D: Velocity is decreasing. Acceleration is increasing.
A: Velocity is zero.
Answer:
As the particles move further away from their normal position (up towards the wave crest or down towards the trough), they slow down.
Explanation:
This means that some of their kinetic energy has been converted into potential energy – the energy of particles in a wave oscillates between kinetic and potential energy. Hope that this helps you and have a great day :)
