Answer:
Allison is probably looking at the asteroid.
Explanation:
- Asteroids are the giant gas balls of inner solar system that are present in the space.
- Asteroids orbits around the sun in very irregular ans strange path unlike the other planets.
- This is also the reason why it's called as the minor planets.
- It could have been comet but if it had been a comets he must have seen the tail but asteroids do not have any tail like structure.
Answer:
F = 1400 N
Explanation:
It is given that,
Mass of the ball, m = 70 kg
It is moving with an acceleration of 20 m/s². We need to find the force exerted by the ball.
Force is given by the product of mass and acceleration. So,
F = ma

So, the force of 1400 N is exerted by a metal ball.
The ice cubes were floating in water because they are less dense than liquid water. When water is frozen, a structure that is crystalline is formed that is held by hydrogen bonding. Due to the orientation of these bonds, the moleules would push far away from each other causing it to have a bigger volume and a lower density.
Slow down before entering the curve. Stay close to the outside. Use the gas pedal as you enter the middle of the curve.
Answer:
The correct option is;
- 4x
Explanation:
From the inverse square law, as the distance from the source of a physical quantity increases, the intensity of the source is spread over an area proportional to the square of the distance of the object from the source
The inverse square law can be presented as follows;

As the distance, r, increases, the surface it covers also increases by the power of 2
Therefore, where the distance increases from r to 2·r, we have;
When, I, remain constant

The surface increases to 4·S by the inverse square law
Therefore, the correct option is 4 × x.
