Exoplanets (planets outside our solar system) are an active area of modern research. Suppose you read an article stating that th

ere is a newly discovered planetary system with three planets. The article states that the outermost planet (Planet C) goes all the way around its star in less time than the innermost planet (Planet A). According to Kepler’s laws of planetary motion, is this possible?

Answer:

Not possible.

Explanation:

Exoplanets are an active area of modern research. The article states that the outermost planet (Planet C) goes all the way around its star in less time than the innermost planet (Planet A). Which is not possible as it will violet Kepler's third law of planetary motion.  Which says that the square of orbital period of a planet is proportional to the cube of its semi-major axis of its orbit.

viva [34]

Explanation:

Since it is mentioned that the block is in equilibrium, this means the resultant force is zero, and all the forces cancel out each other.

You have to think it in a way so that, the forward force cancel out the backward force. Check the picture attached, on the forward side,

3N + 5N = 8N which cancel out the backward force of 8N

Marrrta [24]
Because of inertia (Newton's First Law), the person will keep moving forward with the same velocity that they were travelling before the collision. Also, following Darwin's Law of natural selection, it is a mechanism for removing undesirable traits (idiocy) from the human gene pool.

1. Explain how a boulder at rest on the ground can actually be moving at the same time.
Mars2501 [29]

Answer:

I don't know about the 1st one but An object at rest stays at rest and an object in motion stays in motion at a constant speed and direction unless acted upon by an unbalanced force. Or maybe its moving because the earth is moving and gravity is pulling it with.

2. Speed is the rate at which something or someone is able to move. Instantaneous Speed - the speed at any given instant in time. Average Speed - the average of all instantaneous speeds; found simply by a distance/time ratio.

3. Speed = distance divided by time or s=\frac{d}{t}. Some units for speed can be miles, kilometres, feet, or metres.

4. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
