the weight of the balloon is .030 * 10 = 0.3 N
the weight of the gas of volume v is 0.54*10 N
The lifting force of a volume of v m³ of displaced air is 1.29v N
so, we need
1.29*10*v = 0.3 + 0.54*10*v
or
1.29v = 0.03+0.54v
Answer:
Im afraid i need to to know more on what your asking, are you asking what is momentum?
Explanation:
Because therefore it is the quantity of motion of a moving body, measured as a product of its mass and velocity to the state of motion
or
p = mv
I hope this helps and have a good day, or to best that you can make it <33
Answer:
Capacitor, is the right answer.
Explanation:
The unknown element is a Capacitor.
Below is the calculation that proves that it is a capacitor.
We know that for the Capacitor
i = Imax × sin(wt+(pi/2)).
i = Imax × sin ((2 × pi/T) × (T/4) + (pi/2))
i = Imax × sin(3.142) = 0 A
at, t = T/2
wt = (2 × pi/T) × (T/2) = pi
wt + (pi/2) = pi + (pi/2) = ( 3 × pi/2) =
i = Imax × sin(3 × pi/2) = -Imax
Which is in a correct agreement with capacitor therefore, the answer is a Capacitor.
Answer:
The absolute potential 4.0 m away from the same point charge is -50 V.
(A) is correct option.
Explanation:
Given that,
Distance = 2.0 m
Potential = -100 V
Absolute potential = 4.0 m
We need to calculate the charge
Using formula of potential
Where, V = potential
q = charge
r = distance
Put the value into the formula
We need to calculate the potential
Using formula of potential
Hence, The absolute potential 4.0 m away from the same point charge is -50 V.
