Answer:
Velocity on the right side of the cart 
Explanation:
Given
⇒The mass on the left of the cart 
Its velocity 
,
⇒Mass on the right of the cart 
Velocity
We have to find 
From
The law of conservation of linear momentum:
We can say that.
Initial momentum will equalize the final momentum.
And momentum is the product of mass and its velocity.
Assigning one of its velocity as negative because both are in different direction.
Lets call 
Recalling the formula and plugging the values.
So the velocity of the cart on the right side that has a mass of 
is 
Actually Welcome to the Concept of the Treatment.
Basically according to the theory, GAMMA rays are used to treat the cancer.

Answer: yes, a change in mass affects the total, kinetic and potential energy.
Explanation: The formula that defines the total energy of a loaded spring in simple harmonic motion is given below as
E = 1/2 kA²
Where E = total energy
k = spring constant = ω²m
A = amplitude
As we can see from the formulae that the total energy is dependent on the spring constant (k) which in turn depends on the mass of the loaded spring.
Hence an increase in the mass ( with a constant amplitude) will cause a change ( increase) in the spring constant which in turn changes ( increases) the total energy of the system.
The kinetic energy is given as
K.E = mv²/2 where k = ω²m
As we can see, a change in mass of the loaded spring has a direct effect on the kinetic energy.
Potential energy is given as
P.E = kx²/2 where k = ω²m
Since the value of k is directly affected by the mass and the potential energy is affected by the spring constant (k) hence the potential energy is dependent on the mass indirectly hence any change in mass affects the potential energy too
Answer:
Vector Quantity: A physical quantity is said to be a vector quantity when it has both magnitude and direction. The scalar quantities are distance, mass, time, volume, density, speed, temperature, and energy, The vector quantities are weight, velocity, acceleration, and force.
