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.

Answer:

the magnetic field is leaving the sheet

Explanation:

The magnetic force is given by the expression

        F = q v x B

where bold letters indicate vectors, the modulus of this expression is

       F = q v B sin θ

the direction of the force is given by the right hand rule, for a positive charge

the thumb indicates the direction of the speed, in this case from right to left

the palm the direction of the force, in our case upwards

the fingers extended the direction of the magnetic field, this case after fixing the other two components it points out of the blade

In short the magnetic field is leaving the sheet

The vertical force f acts downward at A on the two membered frames. Determine the magnitude of the two components of F directed
galben [10]

Answer:

The magnitude will be "353.5 N". A further solution is given below.

Explanation:

The given values is:

F = 500 N

According to the question,

In ΔABC,

⇒ \angle BCA = (90-30)

⇒             =60^{\circ}

then,

⇒ \angle BAC=(180-45-60)

⇒             =75^{\circ}

Now,

The corresponding angle will be:

⇒ \angle FAC=60^{\circ}

⇒ \angle FAB=70+60

⇒             =135^{\circ}

Aspect of F across the AC arm will be:

= F\times cos(60)

On putting the values of F, we get

= 500\times (.5)

= 200 \ Newton

Component F along the AC (in magnitude) will be:

= F\times cos(135)

= 500\times (-.707)

= -353.5 \ N \
