I know this from the top of my head!

Galileo said that the Earth rotated around the sun, not the other way. The Catholic Churches thought that the sun rotated around the Earth, and they didn't like his idea and it was even worse since he made speeches about it.

Answer:

heliocentric theory

Explanation:

Heliocentric theory :

Heliocentric theory was developed by many astrologers at different time. It was first proposed by Aristarchus and then further promoted by Copernicus, Kepler and Galileo.According to Heliocentric theory earth revolves around the sun.

In 1610, Galileo discovered new telescope and with the help of this telescope he promoted the heliocentric theory of Copernicus. But this theory was against the belief of catholic church, Catholic church believed in geocentric model of the universe which was proposed by Aristotle. According to geocentric model everything should revolve around us it means sun revolves around earth.

Answer:

Power_input = 85.71 [W]

Explanation:

To be able to solve this problem we must first find the work done. Work is defined as the product of force by distance.

$W = F*d$

where:

W = work [J] (units of Joules)

F = force [N] (units of Newton)

d = distance [m]

We need to bear in mind that the force can be calculated by multiplying the mass by the gravity acceleration.

Now replacing:

$W = (80*10)*3\\W = 2400 [J]$

Power is defined as the work done over a certain time. In this way by means of the following formula, we can calculate the required power.

$P=\frac{W}{t}$

where:

P = power [W] (units of watts)

W = work [J]

t = time = 40 [s]

$P = 2400/40\\P = 60 [W]$

The calculated power is the required power. Now as we have the efficiency of the machine, we can calculate the power that is introduced, to be able to do that work.

$Effic=0.7\\Effic=P_{required}/P_{introduced}\\P_{introduced}=60/0.7\\P_{introduced}=85.71[W]$
