Describe briefly how you would check that the rule is horizontal in this experiment. You  may draw a diagram.​
aliina [53]

Answer:

We want to describe how to graph a linear equation.

Explanation:

The given equation is:

y = -4x - 1

a) To graph it, we need to find two points that belong to the line, then we graph the points, and then we connect them with a line.

To get the points, we just need to evaluate the function in two different values of x.

for x = 0

y = -4*0 - 1 = -1

So we have the point (0, -1)

for x = 1

y = -4*1 - 1 = -5

So we have the point (1, - 5)

Now we just need to find these two points and connect them with a line, the graph can be seen below.

b) To check if the graph is correct we can see two things:

in y = -4*x - 1

The y-intercept is -1, this means that the graph should intersect the y-axis at  y = -1

The slope is -4, this means that for each unit increase on x, we should see that the y-value decreases by 4.

Checking those two things we can see if our graph is correct or not.

Which change of state is shown in the model?
leva [86]

Answer: deposition

Explanation:

Try process of elimination. We know it's not boiling because that is basically water turning into gas. It's not condensation because it's not water which collects as droplets on a cold surface when humid air is in contact with it.

A worker pushes a box across the floor to the right at a constant speed with a force of 25N. What
icang [17]

Answer:

Friction between the box and the floor is 25N to the left

Explanation:

There are two forces acting on the box along the horizontal direction:

- The force of push applied by the worker, in the forward direction, F

- The force of friction, F_f, acting in the opposite direction (backward)

So the net force acting on the box is

F_{net}=F-F_f

According to Newton's second law of motion, the net force on an object is equal to the product between its mass (m) and its acceleration (a), so we can write:

F_{net}=ma

And so

F-F_f = ma

However, in this case the box is moving at constant speed; this means that its acceleration is zero:

a=0

Therefore we have:

F-F_f=0

Which means

F_f=F

And since we are told that

F=25 N

This means that the force of friction is also 25 N:

F_f=F=25 N
