Answer:
A switch interrupts the flow of current in a circuit.
Explanation:
Answer:

Explanation:
acceleration is defined as the rate of change of velocity per unit time. Therefore, acceleration, 
where
is change in velocity and t is time
Substituting initial and final velocities with 25 m/s and 10 m/s then using time as given in the question of 3 s then

Therefore, the acceleration is 
Answer:3.49 m/s
Explanation:
Given
Speed of marble at Bottom 
Diameter of loop 
As Energy is conserved therefore Energy at top is equal to energy at bottom

,where
is the velocity at bottom







Answer:

Explanation:
We could use conversation of energy. Total distance the stone will cover will be

the Final velocity will be

Answer:
The water is flowing at the rate of 28.04 m/s.
Explanation:
Given;
Height of sea water, z₁ = 10.5 m
gauge pressure,
= 2.95 atm
Atmospheric pressure,
= 101325 Pa
To determine the speed of the water, apply Bernoulli's equation;

where;
P₁ = 
P₂ = 
v₁ = 0
z₂ = 0
Substitute in these values and the Bernoulli's equation will reduce to;

where;
is the density of seawater = 1030 kg/m³

Therefore, the water is flowing at the rate of 28.04 m/s.
