Answer:

measures of central tendency are numbers that describe what an average or typical within a distribution of data there are three main measures of central tendency mean medium and mold well they are all measuring essential tendency each is calculated differently and measures something different from others

A charge q produces an electric field of strength 4E at a distance of d away. Determine the electric field strength at a distanc

gizmo_the_mogwai [7]

Answer:

c.) 36E

Explanation:

The magnitude of the electric field is given by the expression

$E=k \frac{q}{d^2}$ (1)

where k is the Coulomb's constant, q is the charge that generates the field, and d is the distance from the charge.

In this problem, we have that the magnitude of the field at a distance d is 4E, so we can rewrite the previous equation as

$4E = k\frac{q}{d^2}$

Now we want to determine the electric field at a distance of $d'=\frac{1}{3}d$ away. Substituting into (1), we find

$E' = k \frac{q}{d'^2}=k \frac{q}{(\frac{1}{3}d)^2}=9 k \frac{q}{d^2}$ (2)

We also know that

$4E = k\frac{q}{d^2}$ (3)

So combining (2) with (3), we find a relationship between the original field and the new field:

$E' = 9 \cdot (4E) = 36E$

A remote-controlled car's wheel accelerates at 22.6 rad/s2 . If the wheel begins with an angular speed of 10.2 rad/s, what is th

Lapatulllka [165]

Answer:

70.9pi rad/s

Explanation:

angle turned through = 16

angular acceleration = 22.6 rad/s2

angular speed = 10.2 rad/s

time = ?

angular acceleration = angular speed/time

time = 10.2/22.6

time = 0.45 seconds

angular speed = angle turned through/time

angular speed = (16 × 2pi)/0.45

= 70.9pi rad/s

Rearranged the equation d=10 v=2.5 for t

eimsori [14]

The time of motion of the object at the given speed and distance is 4 seconds.

<h3>Time of motion of the object</h3>

The time of motion of the object is calculated as follows;

t = d/v

where;

d is distance = 10 m
v is speed = 2.5 m/s
t is time of motion

t = 10/2.5

t = 4 s

Thus, the time of motion of the object at the given speed and distance is 4 seconds.

You exert of force of 75 newtons on a rock. You push and you push, but you can't budge it. You are exhausted! How much work did

Rama09 [41]

A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction
