Answer:
Net force= 14 units
The object is unbalanced
Explanation:
The net force refers to the sum of all forces applied to an object. However, the direction of force applied determine the net force. In this question, a boy and girl is pulling a heavy crate at the same time.
This means that the force is in the same direction, hence, the net force will be:
F(N) = 7 + 7 = 14 unit
However, since the pull is occuring at the same direction. This means that the object has a net force, therefore, will move in a particular direction. This means that the OBJECT IS UNBALANCED
The magnitude of electric field is produced by the electrons at a certain distance.
E = kQ/r²
where:
E = electric field produced
Q = charge
r = distance
k = Coulomb Law constant 9 x10^9<span> N. m</span>2<span> / C</span><span>2
Given are the following:
Q = </span><span>1.602 × 10^–19 C
</span><span>r = 38 x 10^-9 m
Substitue the given:
E = </span>
E = 998.476 kN/C
A wooden stick would be best.
The wire and the wrench are both metal and therefore are able to conduct electricity.
Using your finger is obviously dangerous.
Wood is not a conductor so it is the best answer.
The segment of the motion that net force act on the object causing a positive acceleration is segment 1.
<h3>
Motion of an object</h3>
The motion of an object occurs when a net force greater than zero acts on the object.
The force on the object is determined from Newton's second law of motion.
F(net) = ma
where;
- m is mass of the object
- a is acceleration of the object
<h3>Acceleration of the object from the graph</h3>
- Segment 1: the acceleration is positive
- Segment 2: the acceleration is zero
- Segment 3: the acceleration is negative
- Segment 4: the acceleration is zero
Thus, the segment of the motion that net force act on the object causing a positive acceleration is segment 1.

Atomic mass can change through the process of fusion. Another way is, it can also change in nuclear fusion.
