Answer:
The electric force is 
Explanation:
From the question we are told that
The Bohr radius at ground state is 
The values of the distance between the proton and an electron 
The electric force is mathematically represented as
Where n and p are charges on a single electron and on a single proton which is mathematically represented as
and k is the coulomb's constant with a value
substituting values
![F = \frac{9*10^{9} * [(1.60*10^{-19} ]^2)}{(2.63 * 0.529 * 10^{-10})^2}](https://tex.z-dn.net/?f=F%20%3D%20%20%5Cfrac%7B9%2A10%5E%7B9%7D%20%2A%20%20%5B%281.60%2A10%5E%7B-19%7D%20%5D%5E2%29%7D%7B%282.63%20%2A%200.529%20%2A%2010%5E%7B-10%7D%29%5E2%7D)
The physical evidence are the silent witnesses against the perpetrators of a crime
The correct option of what the field inspector packages after the crime scene has been photographed is the option;
Reason:
Physical evidence are evidence that originate from inanimate objects or origin that is nonliving, and includes every material or object that serve as an indicator that someone has committed a crime, or that can link a perpetrator to crime
Examples include; Documents, hair, skin, fingerprints, weapons, soil, or fibers
The field inspector, collects the evidence that shows that a crime has been committed which are the physical evidence, after the crime scene has been photographed
Therefore, the correct option is; <u>Physical evidence</u>

Hi,
The force that acts on hydraulic machine is heavy therefore the content must be something that cannot be compressed by that kind of force, the gas can easily be compressed while a liquid is nearly impossible to.
Answer:
Net Force = 10N
Acceleration = 2m/s^2
Explanation:
calculate the net force and the acceleration on the block
Net force on the block F = mass * acceleration
Net force acting in the positive direction = 4N + 6N = 10N
Mass = 5kg
According to newton's second law;
a = F/m
a = 10N/5
a = 2m/s^2
hence the acceleration on the block is 2m/s^2
Work = force x distance
= 100N (force) x 0.5m (distance)
= 50J
