Answer:
The speed of the water shoot out of the hole is 20 m/s.
(d) is correct option.
Explanation:
Given that,
Height = 20 m
We need to calculate the velocity
Using formula Bernoulli equation
Where,
v₁= initial velocity
v₂=final velocity
h₁=total height
h₂=height of the hole from the base
Put the value into the formula
Hence, The speed of the water shoot out of the hole is 20 m/s.
Answer:
because the muscles press together and prevent the joint from bending any further
Answer:
D_momentum = 3.23[kg*m/s]
Explanation:
The change of moment can be easily determined by applying the principle of momentum and amount of movement
initial data are:
The relation of the temperature and pressure of gas is proportional; if the temperature raises, the pressure will raise at the same rate.
