Answer:
![Mass = 1.99 * 10^{30} kg](https://tex.z-dn.net/?f=Mass%20%3D%201.99%20%2A%2010%5E%7B30%7D%20kg)
Explanation:
Given
![Mass = 1,990,000,000,000,000,000,000,000,000,000\ kg](https://tex.z-dn.net/?f=Mass%20%3D%201%2C990%2C000%2C000%2C000%2C000%2C000%2C000%2C000%2C000%2C000%5C%20kg)

Rewrite using scientific notation
The format of a number in scientific notation is
![Digit = a * 10^n](https://tex.z-dn.net/?f=Digit%20%3D%20a%20%2A%2010%5En)
Where ![1 \geq\ a\geq\ 10](https://tex.z-dn.net/?f=1%20%5Cgeq%5C%20a%5Cgeq%5C%2010)
So the given parameter can be rewritten as
![Mass = 1.99 * 1,000,000,000,000,000,000,000,000,000,000\ kg](https://tex.z-dn.net/?f=Mass%20%3D%201.99%20%2A%201%2C000%2C000%2C000%2C000%2C000%2C000%2C000%2C000%2C000%2C000%5C%20kg)
Express as a power of 10
![Mass = 1.99 * 10^{30} kg](https://tex.z-dn.net/?f=Mass%20%3D%201.99%20%2A%2010%5E%7B30%7D%20kg)
Hence, the equivalent of the mass of the sun in scientific notation is:
![Mass = 1.99 * 10^{30} kg](https://tex.z-dn.net/?f=Mass%20%3D%201.99%20%2A%2010%5E%7B30%7D%20kg)
gravitational force of planet exerted on its object near the surface is known as weight
so here we know that gravitational force of mars is much less than the gravitational force of Earth
So on the surface of mars the Weight of objects must be much less than the weight of object on surface of Earth
so here correct answer must be
<em>D. Your weight would decrease.</em>
Answer:
a) Due to the characteristic that a converging lens focuses light rays from infinity and parallel to its main axis. Therefore, the lens should be placed at a distance "f" from the film, in this way it will form the image of the object placed at infinity in said film.
b) Since the converging lens produces an image of an object placed at a distance of 2f, the lens must be placed at the same distance (2f), so that this object that is placed at a distance of 2f is focused.
Explanation:
Position and momentum.
This is Heisenberg's Uncertainty Principle:
Δx Δp ≥ h ÷ 4π, where Δx is the change in position, Δp is the change in momentum, and h is Planck's Constant.
The starting point for measuring motion is called : The Reference Point.
