Answer:
1. Fleming's left hand rule
2. It must be projected towards the east
Explanation:
Fleming's left-hand rule states that; When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force perpendicular to both the field and to the direction of the current flow. This rule was first put forward by John Ambrose Fleming in the later part of the nineteenth century.
Hence if the thumb, fore finger and middle finger of the lefthand are held mutually at right angles to each other; the thumb shows the direction of motion, the fore finger shows the direction of the field while the middle finger shows the direction of the current.
Hence, if the alpha particle is projected eastwards(at right angles) to the uniform magnetic field, it will be deflected southwards in the magnetic field.
Explanation:
If two particles are involved in an elastic collision, the velocity of the second particle after collision can be expressed as: v2f=2⋅m1(m2+m1)v1i+(m2−m1)(m2+m1)v2i v 2 f = 2 ⋅ m 1 ( m 2 + m 1 ) v 1 i + ( m 2 − m 1 ) ( m 2 + m 1 ) v 2 i .
The mass of the water in the system is one parameter that can be taken into consideration that is kept constant.
Describe a constant.
A constant in science is a kind of unaltered variable that stays constant together with the experimental process.
It is important to take into account a system's constants, which cannot be altered by experiments or observations.
In conclusion, the mass of the water can be taken into consideration as a continuous system parameter.

Answer:
Then final velocity of the coupled system of cars will be 0.58 m/s
Explanation: Let us consider the car-1 is moving towards right (say + ve direction) and car-2 is moving towards left (say in - ve direction), accordingly velocity are considered +ve and -ve.
Applying the conservation of momentum, and let the final velocity of combined system is V m/s
26250 - 9000 = 29500 
V
V = 
= 0.58 m/s
Then final velocity of the coupled system of cars will be 0.58 m/s
