URGENT I WILL GIVE BRAINLIEST
1 answer:
Weight : It is the gravitational attraction force on an object near its surface.
It is always measured in the unit of Newton(N)
it is given by the product of mass and acceleration due to gravity
here we know that mass of the pig is m = 140 kg
also we know that acceleration due to gravity near the surface of earth is approximately g = 9.8 m/s/s
so here we know by above formula
so correct answer will be
<em>D. 1372 N</em>

<u>The correct option is (D). The strength of electric field depends on the amount of charge that produces the field as well as the distance from the charge. </u>
<u> </u>
Further Explanation:
The electric field intensity at a point is the measure of the force exerted by a charge particle on another charge particle in the particular area of its strength.
The electric field intensity at a distance due to a static charge having charge
is directly proportional to the amount of charge and inversely proportional to the square of the distance between them.
The Electric field intensity due to a charge is given as:
Here, is the electric field intensity,
is the amount of charge and
is the distance of the charge from the point.
The above expression of electric field shows that the electric field intensity at a point depends on the amount of charge as well as the distance of the point from the charge.
<u>Thus, the correct option is (D). The strength of electric field depends on the amount of charge that produces the field as well as the distance from the charge. </u>

1) Current: 4.5 A
2) Time taken: 4.7 s
Explanation:
1)
The electric current intensity is defined as the rate at which charge flows in a conductor; mathematically:
where
I is the current
q is the amount of charge passing a given point in a time t
For the wire in this problem, we have
q = 9.0 C is the amount of charge
t = 2.0 s is the time interval
Solving for I, we find the current:
2)
To solve this problem, we can use again the same formula
where
I is the current
q is the amount of charge passing a given point in a time t
In this problem, we have:
I = 3.0 A (current)
q = 14.0 C (charge)
Therefore, the time taken for the charge to move past a particular spot in the wire is
