We are 8 light minutes from the sun. That means two things, we see the sun as it was 8 minutes ago, and we WOULD continue to see the sun for 8 minutes after it disappeared.

A cliff jumper jumps off a cliff with an initial horizontal velocity of 10 m/s. The cliff is 10 meters high. How far from the ba
nalin [4]

Answer:

The distance reached is 14.3 m.

Explanation:

To find the distance reached by the diamond first we need to find the flight time:

t_{v} = \sqrt{\frac{2h}{g}}

Where:

h: is the height = 10m

g: si the gravity = 9.81 m/s²

t_{v} = \sqrt{\frac{2h}{g}} = \sqrt{\frac{2*10 m}{9.81 m/s^{2}}} = 1.43 s

Now, we can find the distance reached:

x = V_{0_{x}}*t_{v}

Where:

V_{0_{x}} is the initial horizontal velocity = 10 m/s

x = V_{0_{x}}*t_{v} = 10 m/s*1.43 s = 14.3 m

Therefore, the distance reached is 14.3 m.

I hope it helps you!

How does the molecular structure of a material influence its physical properties?
kvv77 [185]

All of these properties are due to the chemical structure of the compound. The chemical structure includes the bonding angle, the type of bonds, the size of the molecule, and the interactions between molecules. Slight changes in the chemical structure can drastically affect the properties of the compound.

When the mass of an object increases, the force of gravity
Gemiola [76]
According to the second law of motion, force is equal to the product of mass and acceleration. This means force is proportional to mass. Hence when mass increases, it is understood that force should increase as well. In this case,the answer to this problem is A.
