Both carts experience the same force but Cart A has a greater speed after the recoil.
The given parameters;
- <em>Mass of the cart A = 0.4 kg</em>
- <em>Mass of the cart B = 0.8 kg</em>
Apply the principle of conservation of linear momentum to determine the velocity of the carts after collision;
According to Newton's third law of motion, action and reaction are equal and opposite. The force exerted on cart A is equal to the force exerted on cart B but in opposite direction.
Thus, the correct statement that compares the motion and forces acting on the two carts is "Both carts experience the same force but Cart A has a greater speed after the recoil."

The situation when nuclear fission occurs, some mass is lost is also called the mass defect and as a result the matter turns into energy. If you want to know where the mass does go Albert Einstein will be your helping hand : E = mc^2. Using this formulae you will solve the task and find out the direction of mass.
Answer:
The answer is below
Explanation:
The equation for a linear line graph is given by:
y = mx + b, where y and x are variables, m is the slope of the graph and b is the y intercept (that is value of y when x is zero).
The slope (m) of a line passing through two points is given by:
A) The first line passes through the point (0, 0) and (10, 60). It is represented as (time, velocity). Hence the slope is:
B) The second line passes through the point (10, 60) and (15, 60). Hence the slope is:
C) The third line passes through the point (15, 60) and (40, -40). Hence the slope is:
D) The third line passes through the point (40, -40) and (55, 0). Hence the slope is:
Answer:
The mass of the meter stick is
Explanation:
Here since the meter stick is in equilibrium position its net torque and net force should be equal to zero
Since at the begging the meter stick is balanced at center of the meter stick that means its center of mass should be present at
Now lets consider the later case where stick is balanced by two 5.12 g coins .
Here torque due to two coins =
Torque due to weight of meter stick = =
where m = mass of the meter stick
Here .
Upon equating we will be getting mass of the meter stick =

In a properly conducted experiment, the experimenter controls one part
of the experiment to see what the other parts do.
Example: Experiment to describe the effect of heat on ice.
Take two same-size ice cubes out of the same ice tray in the same fridge.
Place each one on a little temperature-controlled electric pad.
Turn one pad on, to make it warm. Leave the other pad turned off.
You CONTROL one part of the experiment: the amount of heat that
the ice cube gets.
You KNOW that the heat is the only thing different between the two
ice cubes. They're the same size. They were both made from
the same water, and froze in the same tray in the same fridge.
so
You KNOW that any difference will be the result of the heat on one of them.
You WATCH to see what happens to the one that gets the heat.
10).
An hypothesis is a prediction of what you believe may be true.
Once you have it, it's time to do an experiment to find out whether
your hypothesis is true.
Example:
I have an hypothesis. It predicts that when ice gets warm it melts.
Experiment:
Take two same-size ice cubes out of the same ice tray in the same fridge.
Set one ice cube down on the table.
Keep the other one in your hand.
The one in your hand melts while the one on the table is still solid.
Is the hypothesis correct ?
Maybe it is. Maybe it isn't.
We know that there's something about your hand that melts ice.
It may be the warmth. But it may be something else about human skin.
You'll need another experiment, slightly different, to find out if it's the warmth.
