Answer:

1. Seat belts stop your tumbling around inside the car if their is a collision. This increases the time taken for the body's momentum to teach zero, and so reduces the force on it.

2. Their is nothing wrong with the assumption, the only thing is that you are not sure if the dash of the car will bring you to a sudden stop or not so you have to use the seat belt.

Who discovered laws of gravity and motion? He discovered aspects of light and color, leading to today's spectrum analysis

Vitek1552 [10]

Answer:

Sir Isaac Newton

Explanation:

The laws according to which bodies move and how one body attracts another body were developed by Newton. The three laws of motion and the law of universal gravitation were developed by Newton.

In the seventeenth century almost all the refracting telescopes exhibited color distortion. Newton believed that white light had a spectrum which was the reason for this distortion. The lens of a refracting telescope used to act like a prism which caused the dispersion of light proving Newton's hypothesis.

Io maintains a constant orbit around Jupiter because

Free_Kalibri [48]

Answer: C . The gravitational pull from Jupiter is much greater than any other forces acting on Io.

Explanation:

Let's begin by the fact Jupiter is a huge massive planet, therefore the bodies that are closest to Jupiter will have a greater gravitational force than the other bodies. That is the situation with Io, the moon closest to Jupiter.

However, Io's orbit is very elliptical and eccentric compared to the outer moons, resulting in the distortion of its shape by the gravitational force. In fact, Io is considered the most geologically active object in the solar system, due to these variations.

Mountain pull. A large mountain can slightly affect the direction of ""down"" as determined by a plumb line. Assume that we can

Nastasia [14]

Answer:

6.18 um

Explanation:

The plumb line will be pulled down by a combination of the gravitationall pull of Earth and of the mountain. The Earth pulls down and the mountain to the side. Because of this it will fall not in a straight line down, but slightly to the side. Since the plumb line will follow the compound gravity we can imagine a rectangle triangle formed by the plumb line, a vertical line that ends at the same height as the plumb line, and the sideways displacement.

The total gravity will be proportional to the plumb line lenght, the vertical line will be proportional to Earth's gravity and the sideways displacement to the mountain pull.

The gravity of Earth is 9.81 m/s^2

The pull of the mountain will be defined by Newton's law of universal gravitation:

$F = G \frac{m1 * m2}{r^2}$
