Answer: 40m
Explanation: Distance is a function of speed/ velocity and time.
From the question the velocity along the z axis is given as 20 m/s at t = 0 secs We were ask to calculate the distance travelled when t = 2secs.
Recall that,
Velocity = distance travelled / time
Since we're calculating for distance we make it subject of formula;
Distance travelled = velocity * time
= 20m/s * 2s
= 40meter.
Answer: direction
Explanation:
Given
The resultant vector of a force gives us information regarding the direction of the resultant force.
If there are multiple forces acted in a different direction then, the resultant vector describes the direction of the resultant force.
Atoms<span> are </span>neutral<span>; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a </span>neutral atom<span> to give a positive ion or adding electrons to a </span>neutral atom<span> to give a negative ion.</span>
Answer:
Chemists classify chemical reactions in a number of ways: by type of product, by types of reactants, by reaction outcome, and by reaction mechanism. Often a given reaction can be placed in two or even three categories, including gas-forming and precipitation reactions.

Answer:
25 N
Explanation:
When a force is applied to an object, for it to move it has to overcome the frictional force. The frictional force is perpendicular to the surface on which it acts. For an object at rest, it is acted upon by static friction, this friction must be overcome before the object can move, while a moving object is resisted by kinetic friction that prevents it from moving.
Since the box is at rest, it is acted upon by a static friction.
mass = 5 kg, acceleration due to gravity = 10 m/s², static friction coefficient = 0.5
Weight of the box = mass * acceleration due to gravity = 5 * 10 = 50 N
The applied horizontal force (F) is:
