Answer:
7.13559 knots
Explanation:
Maximum power = 10.5 kilowatts
where,
P = Power in kilowatts
s = Desired speed in knots
Here, P = 10.5 kW
The greatest speed of the Olympians was 7.13559 knots
Answer:
The value is
Explanation:
From the question we are told that
The mass of the sphere is m = 18.5 kg
The diameter is
The number of electrons is
The mass of the plastic ball is
The initial acceleration of the ball is
Generally the radius of the sphere is mathematically evaluated as
=>
=>
Generally the force between the ball and the sphere is
Generally this force can also be mathematically represented as
So
Here is the charge removed from the sphere whicn is evaluated as
substituting for e
and is the charge to be removed from the ball
So
Generally the number of electron to be removed from the ball is mathematically represented as
=>
=>

<u>Opinion on Water Conservation </u>
<u> Fresh water sources is always increasing because of population and industry gowth, Even though water eventually returns to Earth through the water cycle, it's not always returned to the same spot, or in the same quantity and quality. By reducing the amount of water we use, we can better protect against future drought years. Saving water can help others with needs of it </u>
