The kilogram (kg) is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015 ×10−34 when expressed in the unit J s, which is equal to kg m2 s−1, where the meter and the second are defined in terms of c and ∆νCs.

IceJOKER [234]

Diagonal of cardboard=displacement to hole

  • √4²+4²
  • 4√2

So displacement till edge

  • 4√2/2
  • 2√2

Total distance

  • 4√2+2√2
  • 6√2ft

From centre to hole displacement

  • 2√2

a 20 kg box is at rest on a level floor. the coefficient of static friction between the box and the floor is 0.35. hillary pushe
Yakvenalex [24]

Answer:

f = 50\,N

Explanation:

Let assume that floor is horizontal. By definition, the force of friction is less or equal to the maximum static friction force. That is to say:

f \leq \mu_{s}\cdot m \cdot g

The maximum friction force is:

f_{max} = 0.35\cdot (20\,kg)\cdot (9.807\,\frac{m}{s^{2}} )

f_{max} = 68.67\,N

By applying Newton's law, the box has the following physical model:

\Sigma F = F - f = 0

Where:

f = F

Real friction is equal to 50 N, which is less than maximum friction force. Therefore, the static friction on the box is:

f = 50\,N

Define light year and explain how and why light years are used to measure distances in the universe
Mashcka [7]
Distances ANYWHERE could be described in terms of inches, feet,
yards, miles, kilometers, nanometers, centimeters, millimeters, or
even AU (Astronomical Units).  But if you tried to use any of these
to describe the distance of anything away from the Earth's surface, 
you'd be faced with a ridiculous number.  It would be very hard to
remember this number or tell other people about it, and impractical
to write this number down in your notebook.

For example: The average distance between Earth and the moon is

38,440,145,820 centimeters,

and the distance to the nearest star outside the solar system
is approximately

1,671,433,491,000 kilometers.

Isn't that ridiculous ! ?

Obviously, we need much bigger units to describe these distances,
so that we can talk about them in more convenient numbers.  so the
light year was invented to fill this need.  It's simply the distance that
light travels through vacuum in one year.

Definition of 1 light year = exactly 9,460,730,472,580,<span>800 meters
