Momentum = mass * velocity
(aka p=mv)
p=0.145*40
p= 5.80 kg m/s
Answer:
Explanation:
Given that:
- Area of the plate of capacitor 1= Area of the plate of capacitor 2=A
- separation distance of capacitor 2,
- separation distance of capacitor 1,
- quantity of charge on capacitor 2,
- quantity of charge on capacitor 1,
We know that the Capacitance of a parallel plate capacitor is directly proportional to the area and inversely proportional to the distance of separation.
Mathematically given as:
.....................................(1)
where:
k = relative permittivity of the dielectric material between the plates= 1 for air
From eq. (1)
For capacitor 2:
For capacitor 1:
We know, potential differences across a capacitor is given by:
..........................................(2)
where, Q = charge on the capacitor plates.
for capacitor 2:
& for capacitor 1:
Answer:
B) laws that require scientists to research certain things
Given that,
mass m = 110 lbs
Force of gravity in Newton, F =?
Since,
1 lbs = 0.45 kg
110 lbs = 110* 0.45 = 49.5 kg
Since, force of gravity equals the weight of the body.
F = W = mg = 49.5 * 9.81
F = 485.595 N
Force of gravity will be 485.595 N.
In order for motion to occur net force is greater than 485.595 N.
