U tell me cause I don’t know
The equation for calculating the Work is very simple that is Work=Force x Displacement. We have a Force given as 209N and displacement = 10 meter.
Putting these values directly in the formula gives us Work = 209N x 10m
Work = 2090 Joule.
The weight of the bricks is not needed hear.
The upper temperature range for stars is : c. 40,000 K
Every object has their own upper and lower temperature
This indicate the maximum possible energy that a star could release to its surrounding if its somehow exploded.
Answer:
Option (D) By observing illuminated mountain peaks in the dark portion of the moon.
Explanation:
Unlike the traditions at the time of Aristotle which considered that the celestial bodies are spherical and perfectly smooth bodies.
But based on Galileo's observations, the zone that was illuminated in the dark region of the moon near the line that separates the illuminated and the shadowy parts, known as terminator was noticed.
On the breaking of the dawn, as the sunlight hit the top of the lunar mountains it lightens up while the valleys are still dark.
