Momentum (in terms of classical mechanics) is defined as p = m*v, where m is the mass and v is the velocity.
Electricity flows from positive to negative
Answer:
Because the planet is far away from the sun
Explanation:
The closer the planet is to the Sun, the greater the pull of the Sun's gravity, and the faster the planet orbits.
While, over here the Pluto is very far away from the Sun so it will have very little gravitational pull and still keeps revolving around the Sun

Answer:
The velocity of cart B after the collision is 1.29 m/s.
Explanation:
We can find the velocity of cart B by conservation of linear momentum:


Where:
is the mass of cart A = 600 g = 0.6 kg
is the mass of cart B = 200 g = 0.2 kg
is the inital velocity of cart A = 0.7 m/s
is the final velocity of cart A = 0.27 m/s
is the initial velocity of cart B = 0
is the final velocity of cart B =?
Taking the left direction as the positive horizontal direction:


Therefore, the velocity of cart B after the collision is 1.29 m/s.
I hope it helps you!
Answer: divide by zero, or square root of a negative
Explanation: If your question is how to get infinity as an answer to a problem, that generally means that the answer is undefined or doesn't exist.
A couple of ways to get that...
- You try to divide by zero. In other words, a problem that asks you to perform something like this: 5/0= or 23/(4-4)= Such a problem will give you an error on a calculator because the answer is infinity or doesn't exist.
- Another way is to try to get the square root of a negative number. That answer doesn't exist as a real number, so
will also give you an error on a calculator.
