Answer:
The following is the relation between electric force and field
Explanation:
Electric force is the magnitude of electrostatic forces between two charges which is directly proportional to product of both charges and inversely proportional to the square of the distance between them.
Here k is the coulumb's constant.
Where as the electric field is the electric force per unit charge. It is the function of electric force. It is the vector quantity and its direction is taken radially inward or outward depending on the nature of charge.
Its equation is
Electric Field
Electric Field units are in volts where as Electric force units are newtons.
To solve this problem we will use Newton's second law in order to obtain the weight of a person. The second law tells us that
F = ma
Where,
m = mass
a = Acceleration
In this particular case, the acceleration is equal to that exerted by the earth through gravitational acceleration, so if the person's weight is 75Kg and the gravity is , the weight of the body will be,
When the elevator is at rest this reads 735.75N and 75Kg (The same mass of the person)
There are three basic steps in a nuclear fission chain reaction are Initiation, Propagation, Termination.
<h3>What are the three steps of nuclear fission ?</h3>1. Initiation
The nuclear fission of is started by the absorption of a neutron; a single atom must react in order for the chain reaction to begin.
2. Propagation:-
With each stage producing additional product, this component of the process is repeated repeatedly. When splits apart, neutrons are released, which start the nuclear fission of more uranium atoms.
3. Termination:
The chain will come to an end eventually. Termination might take place if the reactant is exhausted or if the subsequent neutrons in the chain leave the sample without being absorbed by
.

Answer:
1250
Explanation:
Let's look at this in a simple manner, because it is.
The crane weights 250Kg. Okay.
Since it is hung, there is the acceleration of gravity being applied on it (10m/s²)
Since F = m * a
F = 250 * 10
F = 2500
Now we know that the downward Force is 2500N.
To find the force that is being applied on that 30° angle, we can multiply our 2500N by cos30°, which happens to be .
Therefore, the force pulling the box in the cable's direction is:
