Answer:. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.
Explanation:
According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration.
The speed of the electron is 1.3 * 10^6 m/s
<h3>What is the velocity?</h3>
We know that when the electron gun is shot, the potential energy of the electron is converted into kinetic energy. The mass of the electron is given as 9.11 * 10^-31 Kg.
The energy of the electron is;
eV = 1e * 5V = ev or 8 * 10^-19 J
Given that E = 1/2mv^2
8 * 10^-19 = 0.5 * 9.11 * 10^-31 * v^2
v = √ 8 * 10^-19/0.5 * 9.11 * 10^-31
v = √1.75 * 10^12
v = 1.3 * 10^6 m/s

To solve this problem we will find the net speed, through the two components given. The vertical component will be found through the energy conservation theorem. Finally with speed we will find the momentum as a function of mass and speed. Given the weight we will divide it by the acceleration to find that mass.
The x component is given as
For conservation of energy the vertical component of velocity would be
Here,
m = Mass
g = Gravitational acceleration
h = Height
Replacing we have that the vertical velocity is
The magnitude of this velocity would be
Finally the momentum of the bale would be
Therefore the momentum of the bale the moment it strikes the ground is
The correct answer is option C. <span>All objects reflect some light. If the object is in front of a mirror, the mirror reflects the light back toward the object, and an image is formed by the reflected rays.</span>The mirror reflects light and does not absorb. Reflection can be specular or diffused.
Answer:
The surface charge density on planes A and B respectively is
and
Explanation:
From the question we are told that
The electric field in region to the left of A is
The direction of the electric field is left
The electric field in the region to the right of B is
The direction of the electric field is right
The electric field in the region between the two planes is
The direction of the electric field is right
Let the surface charge density on planes A and B be represented as
From the question we see that
Generally the electric to the right and to the left is due to the combined electric field generated by plane A and B so
=>
Generally the electric field at the middle of the plane A and B is due to the diffencence in electric field generated by plane A and B
i.e
=>
=>
From equation 1
=>
So
=>
