Answer: Resistance =
, Current = 1.56 A, Voltage =4.99 V
The resistance,

where,
is resistivity, A is the area and l is the length of the resistor.
It is given that:

Length, l=2 mm
Area, 
Hence, 
We know, Power, 



We know, Voltage, 
In a closed system, the loss of momentum of one object is same as________ the gain in momentum of another object
according to law of conservation of momentum, total momentum before and after collision in a closed system in absence of any net external force, remains conserved . that is
total momentum before collision = total momentum after collision
P₁ + P₂ = P'₁ + P'₂
where P₁ and P₂ are momentum before collision for object 1 and object 2 respectively.
P'₁ - P₁ = - (P'₂ - P₂)
so clearly gain in momentum of one object is same as the loss of momentum of other object
They both have kinetic energy because they are both moving and have force.
Hope this helped! :)
Use the formula below for this question:

re-arrange to solve for a:

now simply plug in your variables and there's your answer :). If you ever get stuck, you can look up the kinematic equations!
