Answer:
Explanation:
You can consider that the force that acts over the proton is the same to the force over the electron. This is because the electric force is given by:
where E is the constant electric field between the parallel plates, and is the same for both electron and proton. Also, the charge is the same.
by using the Newton second law for the proton, and by using kinematic equation for the calculation of the acceleration you can obtain:
(it has been used that vp^2 = v_o^2+2ad) where d is the separation of the plates, ap the acceleration of the proton, vp its velocity and mp its mass.
By doing the same for the electron you obtain:
we can equals these expressions for both proton and electron, because the forces qE are the same:
Answer:
2.43 m
Explanation:
From the question given above, the following data were obtained:
Number of wave crest = 7
Time = 10 s
Distance between each crest = 2.43 m
Wavelength =?
The wavelength of a wave is simply defined as the distance between two crest or trough of a wave. This simply means that we can obtain the wavelength of a wave by calculating the distance between two crest i.e
Wavelength = distance between each crest.
From the question given above, we were told that the distance between each crest is 2.43 m.
Therefore, the wavelength of the wave is 2.43 m
Answer:
The statement H is the correct one: The number of atoms on the reactant side equals the number of atoms on the product side.
Explanation:
The law of conservation of mass states that mass can not be created or destroyed, just can be transformed. The mass of a system can not be added or removed, thereby the transfer of mass in a reaction must remain constant.
This implies that the mass of the molecules on the side of the reactants before the reaction must be equal to the mass of the atoms on the side of the products after the reaction.
Therefore, the statement H is the correct one: The number of atoms on the reactant side equals the number of atoms on the product side.

Answer:
131.39863 m/s
683205.94 Joules
Explanation:
m = Mass of person = 80 kg
g = Acceleration due to gravity = 9.81 m/s²
h = Height of the drop = 880 m
v = Speed
= Maximum speed = 140 km/h
Here the Potential and Kinetic energies are conserved
The velocity of Fritz Strobl is 131.39863 m/s
Taking friction into consideration
The work done by friction is 683205.94 Joules
All of them will have the same density
