Two opposite forces acting perpendicular to an axis cause
Greeley [361]

Two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.

<h3>What is couple?</h3>

Couple is the pair of force of equal magnitude which acts in opposite direction to each other. The moment of couple is known as the troque, which can be calculate as,

\tau=Fs

Here, (F) is the magnitude of one of the force and (s) is the perpendicular distance of force acting on axis.

Here, the two opposite forces are given which acts perpendicular to an axis. Now suppose there is the magnitude of both the force (F) is equal and the perpendicular distance from the axis is also same.

Thus, from the above definition of moment of couple, they produce, torque or moment of couple.

Hence, the two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.

If the data is skewed we should use the blank for the center and spread
Usimov [2.4K]

Answer:

When it is skewed right or left with high or low outliers then the median is better to use to find the center. The best measure of spread when the median is the center is the IQR. As for when the center is the mean, then standard deviation should be used since it measure the distance between a data point and the mean.

Aspiration is the desire to achieve success, own a prized possession, or rise in life some way. How can aspiration be positive a
My name is Ann [436]
Aspiration can be positive since it allows motivation. For example, the aspiration of one day owning a car motivates a person to work hard. On the other hand, this can have a negative effect when the aspirations are are set too high and not met for instance, someone aspiring a goal of becoming a millionaire was not met. This could affect the person by causing them to loose all motivation and potentially loose themselves and other aspirations.

What it means that [If x is a factor of p(x), what is the value of k?]
kompoz [17]

Answer:

k = -4

Explanation:

Given

P(x) = (3x^2 - 5)(x + k) - 20

x is a factor

Required

Solve for k

x is a factor means that the polynomial can be divided successfully by x.

In other words, x is a zero of the polynomial.

i.e.

x = 0 and P(x) = 0

Substitute 0 for x in P(x)

P(x) = (3x^2 - 5)(x + k) - 20

P(x) = (3*0^2 - 5)(0 + k) - 20

P(x) = (0- 5)(k) - 20

P(x) = (-5)(k) - 20

P(x) = -5k - 20

Substitute 0 for P(x)

0 = -5k - 20

Collect Like Terms

5k = - 20

Divide both sides by 5

k = -4
