What happens when the force of friction is more than the force of a moving object?

The object will slow down.

The object will be unaffected.

The object will continue at the same speed.

The object will speed up.

Answers

Inertia is a force which brings all objects to a rest position. Fast-moving objects have more inertia than slow-moving objects. False - The speed of an object has no impact upon the amount of inertia that it has. Mostly True - Two objects of the same mass can weigh differently if they are located in different locations.

. How much power is used to move a 5 kg mass 28 meters in 8 seconds?

Answers

Answer:

171.5Watts

Explanation:

Given parameters:

Mass  = 5kg

Distance  = 28m

Time  = 8s

Unknown:

Power = ?

Solution:

Power is the rate at which work is done;

       Power  = [tex]\frac{work done }{time taken}[/tex]

Work done  = force x distance = mg x d =

  m is the mass

   g is the acceleration due to gravity

   d is the distance

  Work done  = 5 x 9.8 x 28 = 1372J

     Power = [tex]\frac{1372}{8}[/tex]   = 171.5Watts

A teacher walks back and forth in front of the room during a lesson. He starts at one end of the desk and walk from the door to the window a distance of 4.0m in 5 s. Then he stops, turn around and walk 2.0 m back toward the door in 3 s. He stops here for 10 s and then walk 3 meters toward the door in 6 s. Deduce the average speed of the teacher over the entire 24 s interval?

Answers

Answer:

0.375 m/s

Explanation:

The average speed of an object or a body is given by:

                      total distance traveled/total time taken

In the case of the teacher who walked back and fort:

Total distance traveled = 4.0 + 2.0 + 3 = 9 meters

Total time taken= 24 s

Hence,

Average speed of the teacher = 9/24

                             = 0.375 m/s

Calculate the pressure exerted by mercury column of 76cm high at its bottom. Given that the density of mercury is 13600kg/m³ and g=9.8 m/s².​

Answers

Answer:

P = 101292.8

Explanation:

Use

Pressure p = H D g

H = height ( in metric)

D = density ( in metric )

g = gravity

So

H = 76 cm = 0.76 m

D = 13600 kg/m3

And g = 9.8

P = HDg

= 0.76× 13600×9.8

= 101292.8 pascal

Or = 1.012928 × 10^5

Answers

Answer: 5.4 kg

Explanation:"Recall that force is the result when we multiply the values of an object's mass and acceleration. Mathematically, we have

F = ma

where F is the force (in Newtons, N), m is the mass (in kilograms, kg), and a is the acceleration (in m/s²).

Since we know that the eagle was accelerating at 22.35 m/s² with a force of 120N, we can solve for the eagle's mass as shown below.

m = F/a

m = (120)/(22.35) ≈ 5.4 kg

Hence, the eagle has a mass of approximately 5.4 kg."

Memories
by matthew smith

I remember when I met you
the smile on your face,
Seems like a million years ago -
a different time and place

I remember when I kissed you
the warmth inside my heart,
I thought it'd last a lifetime
I swore we'd never part

I thought about the future
I started making plans,
Forever you'd be my woman
forever I'd be your man

We went together places
so that everyone could see,
The women that I want to share
the rest of my life with me

I told you that I loved you
I told you that I cared,
I told you if you were falling
just look back and I'd be there

I know I didn't have all the answers
sometimes I only guessed,
But, through it all I have to say
"I always tried my best"

I wasn't always perfect
I wasn't always right,
I know sometimes I wasn't
even worthy in your sight

I know I took for granted
the love you had to share,
All I ever wanted was
for you to know I cared

Our lives have changed directions
as sometimes lovers do,
Often time and change
and pave a path that's new

Sometimes I often wondered
just what lies ahead,
Sometimes I'd like to turn back time
and take back what I said

We've both gone different places
we've both gone different ways,
I know sometimes I let you down
when trouble came our way

I know sometimes I did things
you didn't comprehend,
But, through the years and all the tears
our memories will never end........

d = ?
You will be reported if you didn't answer properly​

Answers

Answer:

 v = 344.1 m / s    

 d = 1720.5 m

Explanation:

For this problem we must calculate the speed of sound in air at 22ºC

           v = 331 RA (1+ T / 273)

we calculate

           v = 331 RA (1 + 22/273)

           v = 344.1 m / s

the speed of the wave is constant,

           v = d / t

           d = v t

we calculate

           d = 344.1   5

           d = 1720.5 m

the diagram below shows different weights on the see-saw. Will the see-saw move?

Answers

Answer:

yes it will

Explanation:

As the net torque on the see-saw  is not equal to zero, the see-saw in the given diagram will move.

What is torque?

The force that can cause an object to rotate along an axis is measured as torque. In linear kinematics, force is what drives an object's acceleration. Similar to this, an angular acceleration is brought on by torque.

As a result, torque can be thought of as the rotational counterpart to force.  Torque is referred to using a variety of terms, including moment and moment of force. The moment arm or lever arm is the measurement of the separation between the point of application of force and the axis of rotation.

The net torque on the see-saw = 3 N × 1.20m - 8 N × 0.50 m

= - 0.4 N-m.

As the net torque on the see-saw  is not equal to zero,  the see-saw move will move.
