Answer:
The answer is D (It reduced his average
force.)
Answer:
They both have a reflection, but a mirror just reflects anything in front of it, while a magnifying glass helps you see closer through the reflection of something.
Explanation:
It would be A because he wanted to know more about the physical properties of these particles like their mass
Answer:
The amount of energy wasted by light bulb 2 = 70 J
Explanation:
Sankey diagrams are used to graphically indicate the proportional flow rate of a quantity
The labelled Sankey diagrams, here, indicate the energy transfers in two light bulbs, light bulb 1 and light bulb 2
From the labelled Sankey diagrams, we have;
For light bulb 1, the input energy = 80 J
The useful energy = 40 J
The wasted energy = 80 - 40 = 40 J
For light bulb 2, the input energy = 80 J
The useful energy = 10 J
Therefore, the wasted energy = 80 - 10 = 70 J
The amount of energy wasted by light bulb 2 = 70 J.
Answer:
755.37 N
Explanation:
We are given that
Mass of venus=
Radius=
m
Mass of human=
We know that the gravitational force between two bodies
Where G=Gravitational constant=
Using the formula
The magnitude of the gravitational force exerted by Venus on the human=
The magnitude of the gravitational force exerted by Venus on the human=F=
