Answer: the answer is 35.4
Explanation: the formula is mass x acceleration = tension - weight
weight is (3kg x 9.8 m/s)
acceleration is 2 m/s
mass = 3kg
Explanation:
a couple is a system of forces with a resultant moment but no resultant force. A better term is force couple or pure moment. Its effect is to create rotation without translation, or more generally without any acceleration of the centre of mass.
Answer:
Electric field at a distance of 1.45 cm will be 
Explanation:
We have given the distance d = 1.45 cm = 0.0145 m
And the potential difference 
There is a relation between potential difference and electric field
Electric field at a distance d due to a potential difference is given by
, here E is electric field, V is potential difference and d is distance
So 
Due to difference in electric potential.
<h3>What is Potential difference?</h3>
The amount of work in an electrical field to move a unit charge from one place to another is known as the electrical potential difference.
Here , the potential difference is the difference in electric potential between two charged substances.
Current is the flow of charges from one end end to another end of a conducting wire connected across a two terminals of a battery.
The potential difference is [provided by the battery across the two terminals due which the charges flow.
Current flow is from positive to negative terminals, indicating the movement of positive charges in that direction.
Hence , potential difference causes the electric charges to flow from one end of the battery .

Weight of an object is given by the formula W = m x g , where
m : mass of the object
g : gravitational acceleration
It is <u>independent of the horizontal </u><u>acceleration</u>.
<h3>What do we mean by weight of an object?</h3>
Weight is a gauge of how strongly gravity is<u> pulling something down.</u> It is dependent on the object's mass, or how much matter it consists of. It also depends on the <u>object's uniformly distributed</u> downward acceleration caused by gravity.
This equation can be used to express weight:
W = m x g
<h3>What is the difference between weight and mass of an object?</h3>
In everyday speech, the phrases "mass" and "weight" are frequently used interchangeably; nevertheless, the two concepts don't have the same meaning. In contrast to weight, which is a <u>measurement of</u> how the <u>force</u> of gravity works upon a mass, mass is the <u>amount of substance</u> in a material.
