Flase plant cells and animals cells have almost the same major parts but some parts are different or in different places
Answer:
The mechanical advantage is 1.
Explanation:
Given;
input force, F₁ = 10 N
output force, F₀ = 10 N
mechanical advantage is called force ratio and it is given as;
M.A = output force / input force
M.A = 10 N / 10 N
M.A = 1
This is an ideal machine scenario.
Therefore, the mechanical advantage is 1.
The coefficient of restitution is a measure of the interaction of the ball with the material of the ground. Since the ground is too solid to move (usually), or give way, the energy of the ball-ground system must be conserved in the main. Some of the energy is released as sound waves but the rest is given to, or reflected back to the ball and it follows the path of reflection. When the ball is dropped vertically it returns along the same path. So the force is actually the potential energy created by dropping converted to kinetic energy on collision with the ground. This is the origin of the force making it bounce.
Hi there!
To solve, we need to find the distance traveled by the proton at which the proton's velocity reaches 0 m/s. This indicates the point at which the repulsive force caused by the line of charge and its consequential acceleration causes the proton to stop for an instant and be repelled back in the opposite direction.
For this, we can use the work-energy theorem to solve.
Recall the following equations:
We will integrate along the path from the point 19.0 cm (0.19 m) from the line up to a point 'z' at which the proton has no kinetic energy (v = 0 m/s). This means that the wire will be doing NEGATIVE work on the proton as it is decreasing the proton's kinetic energy.
The equation for a force acting on a charged particle is given as:
For an infinite line of charge, the electric field is given as:
**λ = Linear charge density (C/m)
To set up our integral:
Integrate using the following natural log rule:
Now, we can begin solving for 'a'.
Move coefficients to one side:
Take the base 'e' of both sides:
It will reach a distance 18.03 cm from the wire before it temporarily loses all of its kinetic energy (at rest) and begins to speed up in the opposite direction.
