Answer:
E = 5291.00 N/C
Explanation:
Expression for capacitance is
![C = \frac{\epsilon A}{d}](https://tex.z-dn.net/?f=C%20%3D%20%5Cfrac%7B%5Cepsilon%20%20A%7D%7Bd%7D)
where
A is area of square plate
D = DISTANCE BETWEEN THE PLATE
![C = \frac{\epsilon\times(19\times 10^{-2})^2}{1.5\times 10^{-3}}](https://tex.z-dn.net/?f=C%20%3D%20%5Cfrac%7B%5Cepsilon%5Ctimes%2819%5Ctimes%2010%5E%7B-2%7D%29%5E2%7D%7B1.5%5Ctimes%2010%5E%7B-3%7D%7D)
![C = 24.06 \epsilon](https://tex.z-dn.net/?f=C%20%3D%2024.06%20%5Cepsilon)
![C = 24.06\times 8.854\times 10^{-12} F](https://tex.z-dn.net/?f=C%20%3D%2024.06%5Ctimes%208.854%5Ctimes%2010%5E%7B-12%7D%20F)
![C =2.1\times 10^{-10} F](https://tex.z-dn.net/?f=C%20%3D2.1%5Ctimes%2010%5E%7B-10%7D%20F)
We know that capacitrnce and charge is related as
![V = \frac{Q}{C}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7BQ%7D%7BC%7D)
![= \frac{2\tiimes 10^{-9}}{2.\times 10^{-10}}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B2%5Ctiimes%2010%5E%7B-9%7D%7D%7B2.%5Ctimes%2010%5E%7B-10%7D%7D)
v = 9.523 V
Electric field is given as
![E = \frac{V}{d}](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7BV%7D%7Bd%7D)
= ![\frac{9.52}{1.8*10^{-3}}](https://tex.z-dn.net/?f=%5Cfrac%7B9.52%7D%7B1.8%2A10%5E%7B-3%7D%7D)
E = 5291.00 V/m
E = 5291.00 N/C
Answer:
Explanation:
The net force on the potatoes is given by:
F= 52 - mgSintheta
F= 52- (2×9.8× Sin70°)
F = 52 -18.4
F= 33.58N
Using Newton's 2nd law
F = ma
a=F/m = 33.58/ 2 = 16.79m/s^2
Using the equation of motion:
V^2= u^2 + 2as
V^2 = 0 + 2× 16.79 x2
V^2 = 67.16
V=sqrt(68.16)
V= 8.195m/s This is the exit velocity of the potatoes
Kinetic energy, K.E = 1/2mv^2
KE= 1/2 × 2 × 8.195^2
KE = 67.16J

Answer:Kinetic energy is the energy of motion. All moving objects have kinetic energy. When an object is in motion, it changes its position by moving in a direction: up, down, forward, or backward. 3. A force is a push or pull that causes an object to move, change direction, change speed, or stop.
Explanation: Not sure if that's what you meant but that's the answer I can give you.
Answer:
246.28 K
Explanation:
The total energy of one mole of gas molecules can be calculated by the formula given below
E = ![\frac{3}{2}\times R\times T](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%5Ctimes%20R%5Ctimes%20T)
Where R is gas constant and T is absolute temperature.
Put the value of R as 8.314 and temperature as 245 , we get
E = ![\frac{3}{2}\times 8.314\times 245](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%5Ctimes%208.314%5Ctimes%20245)
= 3055.4 J
Add 16 j to it
Total energy of gas molecules = 3055.4 + 16 = 3071.4 J.
If T be the temperature after addition of energy then
= 3071.4
T =![\frac{2\times 3071.4}{3\times 8.314}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Ctimes%203071.4%7D%7B3%5Ctimes%208.314%7D)
T = 246.28 K
