Hello!
A portable DVD player requires six 1.5-volt batteries to operate. If the resistance in the circuit is 7.2 ohms, what is the current?
Data:
We have six 1.5 volt batteries, soon, your tension (V)
V = 1.5 * 6 = 9 Volts
R (resistance) = 7.2 ohms
I (Current intensity) = ? (in Amps)
Solving (Ohm's First Law):
Answer:
The current is 1.25 amps

This is your perfect answer
The base unit for time is the second (the other SI units are: metre for length, kilogram for mass, ampere for electric current, kelvin for temperature, candela for luminous intensity, and mole for the amount of substance). The second can be abbreviated as s or sec.
Assume orange is going from left to right and apple is going from right to left
If mv is the momentum of apple at angle θ to the x axis,
In the x direction
0.130*v cos θ = (0.170*1.23) -(0.130*1.08)
0.130*v cos θ = 0.0687-------------------------2
In the y direction
0.130*v sin θ = (0.170*0.974) = 0.16558--------------1
From 1 and 2
tan θ = 2.41
θ = 74.96º
Substituting the value of θ in
0.130*v cos θ = 0.0687
v = 1.38 m/s
