According to Ohm's Law, the voltage is equal to the current multiplied by resistance. Presenting the law in equation form:
V = IR
This law still applies in an R2-D2 droid circuit. Rearranging the equation:
I = V/R
Hence, the current is inversely proportional to the resistance.
Answer:
a)The direction the frictional force will acts is in the positive x direction.
Explanation:
a)The direction the frictional force will acts is in the positive x direction
b)in the horizontal direction, the total force F(total) is equal to 4times the frictional force in the wheel.
F(total)=4f
''f'' is taken as the frictional force.
c)4times the normal force on each wheel minus the acceleration equals zero i.e 4N(wheel)-a=0
=4N(wheel)-mg=0
d) torque is the force that tends to bend rotation
ζ=rf
but acceleration=4×frictional force
cross multiply
f=ζ/r
f=ma/4
ma/4=ζ/r
a=4ζ/r
It can be found in granitic and basaltic rock.
This matter is called medium
