maximum allowed value of the speed in roller coaster is given as
now from kinematics we can say
here initial speed will be
acceleration is due to gravity
now we can use this to find the height
so maximum allowed height will be 20.4 m

The total work done by the electric field on the charge is given by the scalar product between the electric force acting on the charge and the displacement of the charge:
where the force is F=qE, d=0.556 and
. Using the value of q and E given by the problem, we find
where the force is F=qE, d=0.556 and
Answer:
1 ohm
Explanation:
since there are two identical resistors, one resistor will be
R = =2ohm [ proven as in series
]
to calculate the equivalent resistance when in parallel:
so,
