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
Answer:
speed is 25.43 85 x 10^5 m/s
Explanation:
momentum = 7.25 x 10^5 kg.m/s
mass = 0.285 kg
to find out
speed
solution
we have given mass and momentum so
to find speed we apply here momentum formula that is
momentum = mass × speed ...................1
put here all value and find speed
speed = momentum / mass
speed = 7.25 x 10^5 / 0.285
speed = 2543859.649
so speed is 25.43 85 x 10^5 m/s
Answer:
Explanation:
Electricity is generated from solar energy predominantly by the use of photovoltaic cells.
The sun is the ultimate source of energy for all life and the bulk of the solar system at large.
Energy from the sun is used for various life processes and other abiotic uses.
In order to harness the sun's energy to produce electricity, a photovoltaic cell is required. These cells are often used in making solar panels which are available in most places today.
Electricity is produced by the movement of electrons within a cell or a body. In a photovolatic cell, the radiation from the sun causes chemical reactions to occur on the surface of these materials. The reaction is such in which electrons are produced. The movement of electrons in these cells results in the generation of electricity.
In some other cases, sunlight can be concentrated for heating water to produce steam. Steam can be used to drive turbines to produce electricity too.
Handball players move the ball by taking turns hitting it towards the wall so it will bounce back and be available for the opponent to hit. This repeats until one of the players either misses the ball or hits it in a way that it doesn't bounce back.
I would assume gamma rays because they have the fastest moving partials out of all of them
