Different forces can have simillar magnitudes and same directions (but opposite), in this case the result will be nothing would happen. Or one of forces can be bigger than the other/s (in the same direction) so the system would accelerate (F=ma). Or there could be a situation with the same magnitudes but different directions, so the object (system) would accelerate in the direction of secant line (F=ma)
A.) i.) Mass of Proton is slightly lower than the neutron and electrons are too lighter as compared to them.
ii.) Proton has positive charge, Electron with negative, and neutrons does not have any charge.
iii.) Proton and Neutron resides under the nucleus so known as "Nucleons" whereas electrons revolve around the nucleus.
B.) Protons and Neutrons determine the atomic mass of an atom, and protons and electrons determine the charge upon it. They are the basic properties and many chemical predictions could be made by this information.
Hope this helps!
The correct answer is anthracite
Answer:
raise the board to a higher angle
Explanation:
Static friction is the force opposite to the applied force.
Static friction is dependent on the angle of inclination, it means as the angle of incline increases, the force of friction will increases as normal force will decrease.
So, if the board will be raised to a higher angle, it will increase the angle of incline and will overcome the static friction and block will be able slide.
Hence, the correct option is "raise the board to a higher angle".
Answer: 178.25*10^-6 T
Explanation: In order to solve this problem we have to take into account the equilibrium between the electric and magnetic forces in the electron, so it is given by:
Fm=evB
Fe=eE so
evB=eE the we have
v=E/B
Firsly we calculate the velocity of the electron before to get the parallel plates at 100V
eΔV=1/2*m*v^2 then
v=(2*eΔV/m)^1/2
v=(2*1.6*10^-19*3.1*10^3/9.1*10^-31)^1/2=33 *10^6 m/s
Then we can calculate B
B=E/v E.d=V where d is the separation between the plates and V is equal a 100V
B=V/(d*v)=100/(17*10^-3*33 *10^6)=178.25*10^-6 T
