Answer:
(a) They must have same direction
(b) It is not necessary for them to have same magnitudes
Explanation:
(a)
Momentum is a vector quantity. It is the product of mass (scalar) and velocity (vector). Thus, if the direction of velocity is changed, then as a result the direction of momentum will also change or its magnitude or component in the same direction will change. Hence, for the two objects to have same momentum, the directions of their velocities must also be the same.
(b)
Since, the momentum is product of velocity and mass. It is possible that two bodies of different masses with different velocities might have same momentum, provided the direction of their velocities is same.
For example, take a body of mass 4 kg moving with speed 5 m/s. It will have a momentum of 20 N.s. Now, consider another body of mass 2 kg, moving with speed 10 m/s. It will also have a momentum of 20 N.s.
Thus, it is not necessary for two objects to have same magnitude of velocity to have same momentum.
To increase the force required to move an object without change mass is : To increase the acceleration of the object
<h3>Force acting on an object </h3>
Given that Force = Mass * acceleration
An increase in the acceleration of an object in motion will result in a proportional increase in the Force required to move the object becasue force of an object is directly proportional to the acceleration of an object.
Hence we can conclude that To increase the force required to move an object without change mass is To increase the acceleration of the object.

Answer:
Based on what we have learned so far, in what ways have the experiences of Asian-Canadians stayed the same over time? Why do you think these similarities exist? Please give specific examples to support your ideas.
Explanation:
Answer: 33
Explanation:
12+3=15, so in 3 years time Ruto will be 15.
Because 15 is said to be 1/3 times his fathers present age (x), you can plug that into an equation.
15=1/3(x)
Then solve the equation.
(3)15=[1/3(x)]•3
45=x
His father is currently 45, so if you subtract 12 from that, you get 33.
Ruto’s father was 33 years old 12 years ago.
