Solve for "x"
X=force
18/6=x/9
cross multiply 
162=6x
x=27
Hope this helps

A dentist’s drill starts from rest. After 4.28 s of constant angular acceleration it turns at a rate of 28940 rev/min. Find the
mylen [45]

Answer:

Angular acceleration, is 708.07\ rad/s^2

Explanation:

Given that,

Initial speed of the drill, \omega_i=0

After 4.28 s of constant angular acceleration it turns at a rate of 28940 rev/min, final angular speed, \omega_f=28940\ rev/min=3030.58\ rad/s

We need to find the drill’s angular acceleration. It is given by the rate of change of angular velocity.

\alpha =\dfrac{\omega_f}{t}\\\\\alpha =\dfrac{3030.58\ rad/s}{4.28\ s}\\\\\alpha =708.07\ rad/s^2

So, the drill's angular acceleration is 708.07\ rad/s^2.

A Sonometer wire of length
Scrat [10]

Answer:

-75 cm

Explanation:

At l ; F = 350 Hz

At l + 15 cm ; F = 280 Hz

I = 350

I + 15 = 280

280I = 350(I + 15)

280I = 350I + 5250

280I - 350I = 5250

-70I = 5250

I = - 75cm

The length is - 75 cm

The center of gravity is defined as: a. The part of the skeleton composed of the bones of the vertebral column, ribs, and skull
mr Goodwill [35]

Answer:

d. Imaginary point through which the resultant force of gravity acts on an object

Explanation:

Gravity acting on all particle points of the object, no matter how small they are. As a combination, the center of gravity would denote a single point which  substitutes for all the gravity forces on the object.
