Answer:
Explanation:
Given that:
length of side , a = 0.5 m
charge , q = 6.65 mC
length of diagonal , d = 0.5 * sqrt(2)
d = 0.707 m
F is the force due to adjacent particle ,
F1 is the force due to diagonal particle
Now , for the net charge on a particle
Fnet = 2 * F * cos(45) + F1
Fnet = 2*cos(45) * k * q^2/a^2 + k * q^2/d^2
Fnet = 9*10^9 * 0.00665^2 * (2* cos(45)/.5^2 + 1/.707^2)
Fnet = 3.05 *10^6 N
the magnitude of net force acting on each particle is 3.05 *10^6 N
part B)
for the direction of particle
d) along the line between the charge and the center of the square outward of the center
The ratio of (new volume / old volume) is the same as the ratio of (new temperature / old temp).
Just remember that you have to use the ABSOLUTE temperatures.
An absolute temperature is (Celsius + 273).
Answer:
calar quantity, length of path. displacement: vector quanity, "as the crow flies" difference between start and finish regardless of path taken. Term.
Explanation:
Answer:
Option B and Option C
Explanation:
As we know that the wavelength of light is dependent on its speed. In fact the wavelength of light is directly proportional to the speed of the light. If the speed increases, the wavelength will also increase. While moving from air to acetone the speed of light reduces, and hence the wavelength reduces.
Wavelength is inversely proportional to the frequency. In acetone, the wavelength of light reduces, thus the frequency must increase and it should be higher than the frequency of light in air.
Option B and C are correct
Answer:
P V = N R T ideal gas equation
V1 = k * T1 if P is constant and also N and R will be constant
V2 = k * T2 where k is some constant
Or V2 = (T2 / T1) * V1 also known as "Charles Law" for expansion at
constant pressure
V2 = (373 / 273) * 1000 cm^3 = 1366 cm^3 where T is absolute temperature
