Answer:
Answer:
6.68 x 10^16 m/s^2
Explanation:
Electric field, E = 3.8 x 10^5 N/C
charge of electron, q = 1.6 x 10^-19 C
mass of electron, m = 9.1 x 10^-31 kg
Let a be the acceleration of the electron.
The force due to electric field on electron is
F = q E
where q be the charge of electron and E be the electric field
F = 1.6 x 10^-19 x 3.8 x 10^5
F = 6.08 x 10^-14 N
According to Newton's second law
Force = mass x acceleration
6.08 x 10^-14 = 9.1 x 10^-31 x a
a = 6.68 x 10^16 m/s^2
Explanation:
It would take more energy to reheat 12 cups because only 1 or 2 cups can fit in a microwave rather an than brewing 12 cups in a coffee pot.
The rate in witch ditermans the speed or vibration of the movment under the waves witch couses vibrational freequencys to be disrupted.
Answer:
2000 V/m
1778021.69323 m/s
Explanation:
V = Voltage = 9 V = 
q = Charge of proton = 
m = Mass of electron = 
v = Velocity of electron
Electric field is given by
The electric field is 2000 V/m
Here, the energy of the system is conserved
The velocity of the electron is 1778021.69323 m/s
Because a star is a peace of the sun and the sun is hot so the star get it energy from the Sun .
