Question 17 ListenA blue lab cart is traveling west on a track when it collides with and sticks to a red lab cart traveling east. The magnitude of the momentum of the blue cart before the collision is 2.0 kilogram • meters per second, and the magnitude of the momentum of the red cart before the collision is 3.0 kilogram • meters per second. The magnitude of the total momentum of the two carts after the collision is1.0 kg • m/s2.0 kg • m/s3.0 kg • m/s5.0 kg • m/s

Answers

Answer 1
Answer:

Answer:

option A

Explanation:

given,

momentum of blue car in west direction = Pa = 2 kg.m/s

momentum of red cart in east direction = Pb = 3 kg.m/s

total momentum of the two cart = ?

Pa = 2 Kg.m/s

Pb = -3 kg.m/s

Total momentum

P = Pa + Pb

P = 2  - 3

P = - 1 kg.m/s

hence, the total momentum of the two carts after the collision is 1.0 kg•m/s

The correct answer is option A

Nothing happens to it. Mass doesn't depend on gravity.

When an electric current is passed through water during the process of electrolysis two gases are formed one gas has a boiling point of -183 c and the other has a boiling point of -253 change or a chemical change occurred explain had a physical change or a chemicial change occurred explain?

Answers

There is a chemical change because the liquid water, after passing an electric current, produces hydrogen and oxygen gases. This is a reaction. The molecular component of eater has been broken down into two. These two gases have different structures compared to water.

Epsilon Eridani is a star that is 10.5 light years away from Earth. One light year is about 9.46 trillion kilometers The distance between the star and Earth in kilometers is trillion kilometers?

Answers

Given the relation that 1 light year = 9.46 trillion kilometers, and the distance from Epsilon Eridani to Earth which is 10.5 light years, we can solve for the distance between the star and Earth in light years by multiplying both values together. This is shown below

Dsitance (in trillion km) = 9.46 trillion km * (10.5) = 99.33 trillion kilometers

Answer:99.33

How much energy is contained in matter with mass of 1 gram (0.001 kilogram)

Answers

The mechanical energy consisting of potential and kinetic energy is:

           0.001 x [ (acceleration of gravity x height) +  (1/2) (speed)² ] .


You want to know how much [ mc² ] there is in 1 gram of mass.

           E = m c² = (0.001) x (3 x 10⁸)² = 9 x 10¹³ joules

That's the energy that a 1,000-watt toaster uses

A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500 J. What is the mass of the soccer ball?

Answers

A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500 J.The mass of the soccer ball is 0.4 kgs. This answer is derived from the formula K=1/2 MV^2.So velocity and kinetic energy are given from that mass of the ball is calculated.By substituting the values 500=1/2*M*50*50 which gives M=0.4 Kgs.

Answer:

C.0.4 kg

This is your answer!
