A potter’s wheel of radius 17 cm starts from rest and rotates with constant angular acceleration until at the end of 32 s it is

moving with angular velocity of 20 rad/s.
A) What is the angular acceleration?
B) What is the linear velocity of a point on the rim at the end of the 32 s?
C) What is the average angular velocity of the wheel during the 32 s?
D) Through what angle did the wheel rotate in the 32 s?

Answer:

α=0.625rad/s^2

v=340m/s

w=10rad/s

θ=320rad

Explanation:

Constant angular acceleration = ∆w/∆t

angular acceleration = 20/32

α=0.625rad/s^2

Linear velocity v=wr

v = 20×17= 340m/s

Average angular velocity

w0+w1/2

w= 0+20/2

w= 20/2

w=10rad/s

What angle did it rotate with

θ=wt

θ= 10×32

=320rad

The carbon monoxide molecule (CO) consists of a carbon atom and an oxygen atom separated by a distance of
valkas [14]

Answer:

6.46*10^-11m

Explanation:

We can use the equation of the center of the mass of two atoms

Xcm=\frac{mcxc+moxo}{mc+mo}

If we take the origin at the center of the molecule carbon monoxice, xc will be 0, so

Xcm=\frac{moxo}{mc+mo}=\frac{xo}{mc/mo+1}

Xcm=\frac{1.13.10^-3}{0.750mo/mo+1}=6.46*10^-11m

An object is moving with constant non-zero velocity. Which of thw following statements about it must be true
hram777 [196]

Answer:

The net force on the object is zero.

Explanation:

An object is moving with constant non-zero velocity. If velocity is constant, it means that the change in velocity is equal to 0. As a result, acceleration of the object is equal to 0. Net force is the product of mass and acceleration. Hence, the correct option is (d) "The net force on the object is zero".

An object is dropped from an airplane and takes 72 seconds to hit the ground. What is the magnitude of its VF Y ?
Dafna1 [17]

The final vertical velocity of the object is 705.6 m

Explanation:

Here we have to analyze the vertical motion of the object, which is a free fall motion, with constant acceleration of

g=9.8 m/s^2

towards the ground due to gravity.

Therefore, we can use the following suvat equation:

v=u+at

where

v is the final vertical velocity

u is the initial vertical velocity

a=g is the acceleration

t is the time

Since the object is dropped,

u = 0

Therefore, the magnitude of the vertical velocity of the object after t = 72 seconds is:

v=0+(9.8)(72)=705.6 m/s
