The speed is 0.2 meter per minute.
There is not enough information given in the question to determine the velocity.
Answer:
Explanation:
Given:
volume of urine discharged,
time taken for the discharge,
diameter of cylindrical urethra,
length of cylindrical urethra,
density of urine,
a)
we have volume flow rate Q:
&
where:
cross-sectional area of urethra
velocity of flow
b)
The pressure required when the fluid is released at the same height as the bladder and that the fluid is at rest in the bladder:
Answer:
A circuit which has a battery in it will not allow electricity to flow through it. A device called a switch can be used to complete a circuit so that other devices can be switched on or off.

Answer: b) Pressure and internal energy increases.
Explanation: According to the temperature and pressure law, also known as Gay-Lussac's Law, pressure and temperature are <u>directly</u> <u>proportional</u>, which means that when temperature increases so does pressure and vice-versa, so, since temperature increased, pressure will also increase.
Internal Energy (Thermal Energy) is the total amount of energy associated with the motion of the atoms or molecules in the system. Temperature and Internal Energy are also <u>directly</u> <u>proportional</u>, because, as temperature increases, the movement of the particles increases and so do its internal energy. So, as temperature rises internal energy also rises.
For this bottle, as temperature rises, both pressure and internal energy also rises, so the right alternative is "Pressure and internal energy increases."
We are
given that:
m = 5.5 kg
d = 12 m
t = 1.75 s
Using the
distance formula, we can get the acceleration of the ball:
d = (1/2) a*t^2
Rearranging:
a = 2d/t^2
= 2*(12 m)/(1.75 s)^2
a = 7.837
m/s^2

Newton’s 2nd law, force is defines as:</span>
F = ma
F = 5.5 kg
(7.837 m/s^2)
