The light bulb... i think ...
In my school, a student
who refuses to wear their uniform gets suspended.
<span>Our school is quite strict
when it comes to our uniform. If you get caught with your tie off, an undone
button or untucked shirt, you will get a 45-minute detention after school.
Sometimes, when a student doesn’t wear their school uniform and the security
guard or the discipline officer catches them, they may also be required to do
community service or have their ID confiscated. Most of the time, this is done
so a student would be a better person that follows the protocols set by an
institution, and this makes a student prepared for the real world, equipped
with good values.</span>
<u>Answer:</u> The correct statement is True.
<u>Explanation:</u>
There are two types of charges in the electric field:
- Negative charge known as electrons
- Positive charge known as holes
The above two are oppositely charged species and we also know that electric current is the flow of free electrons in a current.
Negative charges (Electrons) flow from the negative terminal to the positive terminal while positive charges (holes) flow from the positive terminal to the negative terminal. Thus, they move in the opposite direction.
Hence, the correct statement is True.
Answer:
The velocity is 
The pressure is 
Explanation:
From the question we are told that
The speed at which water is travelling through is 
The pressure is 
The diameter of the new pipe is 
Where D is the diameter of first pipe
According to the principal of continuity we have that
Now 
is the area of the first pipe which is mathematically represented as
and 
is the area of the second pipe which is mathematically represented as
Recall
![A_2 = \pi \frac{[ D^2]}{4 *4}](https://tex.z-dn.net/?f=A_2%20%3D%20%5Cpi%20%20%5Cfrac%7B%5B%20D%5E2%5D%7D%7B4%20%2A4%7D)
So 
substituting value
According to Bernoulli's equation we have that
substituting values
