What are the differences between the practical and the ideal pendulum​

Physics
1 answer:
ankoles [38]3 years ago
4 0

lf a heavy point mass is suspended by a weightless, inextensible and perfectly flexible string from a rigid support, then this arrangement is called simple pendulum.

In practice, however, these requirements cannot be fulfilled. So we use a practical pendulum.

A practical pendulum consists of a small metallic solid sphere suspended by a fine silk thread from a rigid support. This is the practical simple pendulum which is nearest to the ideal simple pendulum.

Note :

The metallic sphere is called the bob.

When the bob is displaced slightly to one side from its mean position and released, it oscillates about its mean position in a vertical plane.

If two point masses 1kg &amp; 4kg are seperated by a distance of 2m. Magnitude of gravitational force exerted by 1kg on 4kg is ?
Aliun [14]

Answer:

  • F = G Newtons

Explanation:

Given:

  • Mass of 1st body = 1\:kg
  • Mass of 2nd body = 4\:kg

To Find:

  • Magnitude of gravitational force

Solution:

Here, we have a formula

  • F=\dfrac{G.M_{1}.M_{2}}{r^{2}}

<u>Substituting the values</u>

\implies\:\:F = \dfrac{G(1)(4)}{2^{2}}

\implies\:\:F = \dfrac{4G}{4}

\implies\:\:F = \dfrac{\cancel{4}G}{\cancel{4}}

\implies\:\:\red{F = G}

Know More:

The applied formula for the above solution is

{\boxed{F_{G}=\dfrac{G.M_{1}.M_{2}}{r^{2}}}}

where,

  • F_{G} = Gravitational force
  • G = Gravitational constant
  • M_{1} = mass of 1st body
  • M_{2} = mass of 2nd body
  • r = distance between two bodies

An object with a mass of 78kg is lifted through a height of 6 meters. How much work is done?
g100num [7]
Work = force x distance. 

force = mass x acceleration 

work = mass x acceleration x diastance 

use acceleration of gravity in this problem 

W (J) = m (kg) x a (m/s/s) x d (m) 
W = 78 x 9.8 x 6 
W = 4586.4

Is there an eclipse happening soon in England
lyudmila [28]

A solar eclipse will be visible over a wide area of the north polar region
on Friday, March 20.

England is not in the path of totality, but it's close enough so that a large
part of the sun will be covered, and it will be a spectacular sight.

For Londoners, the eclipse begins Friday morning at 8:25 AM,when the
moon just begins to eat away at the sun's edge.  It advances slowly, as more
and more of the sun disappears, and reaches maximum at 9:31 AM.  Then
the obscured part of the sun begins to shrink, and the complete disk is
restored by the end of the eclipse at 10:41AM, after a period of 2 hours
16 minutes during which part of the sun appears to be missing.

The catch in observing the eclipse is:

                       <em><u>YOU MUST NOT LOOK AT THE SUN</u></em>.

Staring at the sun for a period of time can cause permanent damage to
your vision, even though <em><u>you don't feel it while it's happening</u></em>.

This is not a useful place to try and give you complete instructions or
suggestions for observing the sun over a period of hours.  Please look
in your local newspaper, or search online for phrases like "safe eclipse
viewing".

Which statement is correct?
NISA [10]

Answer:

1st statement is true

Explanation:

Here statement 1 is correct

Let think about it, if you push down the bar then you are lifting your weight off the pedals.

Obviously, this question does not take into account of racing bikes with straps on pedals, where you would push on one side and pull on the other to match your legs are doing, with straps your other leg can pull pedals upward.
