Answer:
12353 V m⁻¹ = 12.4 kV m⁻¹
Explanation:
Electric field between the plates of the parallel plate capacitor depends on the potential difference across the plates and their distance of separation.Potential difference across the plates V over the distance between the plates gives the electric field between the plates. Potential difference is the amount of work done per unit charge and is given here as 21 V. Electric field is the voltage over distance.
E = V ÷ d = 21 ÷ 0.0017 = 12353 V m⁻¹
Answer:
A. The volume of the object
Explanation:
First of all, it can only PROBABLY be A or D
But why is it only A?
- Mass = The amount of matter in an object (nothing related here)
- Volume = How much space is the object taking (super related here)
It's VOLUME here and not MASS here because:
- It it would be Mass, then the object size could be anything, but the liquid wouldn't move as much higher.
- But because it is Volume, it is taking space, which makes the liquid move
- If the Mass would be the answer, then it would be totally not related, because mass isn't related over here, it matters about size.

Hence, A. The volume of the object </h2>
is your answer!!!!
Answer
given,
mass of the ski = 75 Kg
speed of the skier, v = 3 m/s
time = 1.50 min = 90 s
angle of inclination, θ = 40°
distance = s x t
= 3 x 90 = 270 m
a) W = F. d cos θ
W = mg. d cos θ
W = 75 x 9.8 x 270 x cos 40°
W = 152021.52 J
work is done by the ski lift is equal to 152021.52 J
b) Power extended by the ski
P = 1689.13 Watt.
power is expended by the ski lift is equal to 1689.13 W.
Answer:
L= 2 mH
Explanation:
Given that
Frequency , f= 10 kHz
Maximum current ,I = 0.1 A
Maximum energy stored ,E= 1 x 10⁻⁵ J
The maximum energy stored in the inductor is given as follows
Where ,L= Inductance
I=Current
E=Energy
Now by putting the values in the above equation
L=0.002 H
L= 2 mH
We know that frequency f is given as
C=Capacitance , f=frequency ,L=Inductance
Now by putting the values
Therefore the inductance and capacitance will be 2 mH and 1.26 x 10⁻⁷ F respectively.
