Answer:

Explanation:

Many people did not believed in the discoveries made by Galileo especially the concept of heliocentrism because of a conflict between Catholic church and Galileo.

There were many controversies between the idea of Heliocentrism that Catholic churches have threatened Galileo to abolish it.

There was many other astronomers as well who did not believed in his theory because of absence of stellar parallax and considered this theory as foolish and absurd.

Dan Brown in his novels has very well explained the difference in ideas of Galileo and Catholic church.

A water pump with a power of 3.4 × 102 watts lifts water at the rate of 7.5 × 10-2 meters/second from a water tank. What is the

Neporo4naja [7]

<h2>Hello!</h2>

The answer is:

The correct option is:

C. $4.5x10^{3}N$

To calculate the force exerted by the pump, we must remember the formula to calculate power, also, we must remember that power means work done in a determined period of time.

We have that power can be calculated by the following equation:

$Power(W)=F*V=N.\frac{m}{s}=\frac{N.m}{s}=1Watt$

So, we are given the following information:

$Power=3.4x10^{2}W=340W=340\frac{N.m}{s}\\\\V=\frac{7.5x^{-2}m }{s}=\frac{0.075m}{s}$

Now, substituting and calculating we have:

$Power(W)=F*V$

$340\frac{N.m}{s}=F*\frac{0.075m}{s}$

$F=\frac{340\frac{N.m}{s}}{\frac{0.075m}{s}}=4,533N=4.5x10^{3}N$

Hence, the correct option is:

C. $4.5x10^{3}N$

Have a nice day!
