This planet's mass must be four times that of Earth in order for the gravitational pull at its surface to be comparable to Earth's.
<h3>What is Newton's law of gravitation?</h3>
Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.
The gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.
The planet's mass is directly related to its mass at the surface and inversely proportional to the square of its radius;
When mass increases and distance reduces, gravity rises. Gravity also lowers when the distance between two points grows and the mass decreases.
The astronomers discovered a planet twice the size of Earth that resembles Earth.
This planet's mass must be four times that of Earth in order for the gravitational pull at its surface to be comparable to Earth's.
Hence the masses of this planet will be 4 times that of Earth.

Answer:
What is the elapsed time for Trial B? - 3.0
What is the average speed for Trial B? - 1.3
Explanation:
Answer:
Newton/meter
Explanation:
Acceleration is defined as the rate of change of velocity.
Therefore, the SI units of acceleration is m/sec²
However, acceleration is also involved in Newton's second law:
Force = mass * acceleration
Newton = kg * unit of acceleration
Therefre:
unit of acceleration = Newton / kg
Hope this helps :)
Answer:
e. is definitely zero
Explanation:
Given that
At initial condition the speed of the pop cans is zero.
We know that linear momentum
P = Mass x velocity
P = m v
At initial condition v = 0
P= 0
If there is no any external force then the linear momentum of the system will be conserve.And given that ,consider the system isolated.
Therefore the answer is e.
