Answer:
It will take both pumps 3.08 hours to fill the tank working together.
Explanation:
Pump A can fill the tank in 5 hours. Assuming that the pump gives out a steady flow of water, in one hour, pump A can fill 1/5th of the tank. Similarly, pump B in an hour, fills up 1/8th of the tank.
We must add up these two values, in order to find how much of the tank the two pumps can fill up together in one hour.
1/5 +1/8 =13/40
So 13/40 of the tank is filled in an hour. We need to find how many hours it will take for the entire tank to be filled. To do so, divide 40 by 13. This gives:
3.08 hours to fill up the tank.
<h3><u>Answer;</u></h3>
A. wind, tidal, geothermal, and hydroelectric
<h3><u>Explanation</u>;</h3>
- Renewable energy sources are the energy sources that are constantly being replenished, such as sunlight, wind, and water. This means that we can use them as much as we want, and we do not have to worry about them running out.
- Additionally, renewable energy sources are usually much more environmentally friendly than fossil fuels. Examples of renewable sources of energy includes; solar energy, wind energy, hydroelectric power, tidal energy, geothermal energy, etc.
Answer:
The magnitude of the acceleration is 
The direction is 
i.e the negative direction of the z-axis
Explanation:
From the question we are that
The mass of the particle 
The charge on the particle is 
The velocity is 
The the magnetic field is 
The charge experienced a force which is mathematically represented as
Substituting value
Note :
Now force is also mathematically represented as
Making a the subject
Substituting values
Recall
power = Force × speed
100 = 3.5×10 × V
V = 100÷35 = 2.86 ms-¹
