Answer:

B) is the force of gravity upon an object

Explanation:

Weight is the force of gravity acting upon an object.

  • Weight is dependent upon the force of gravity acting on a body

It is mathematically expressed as;

          Weight  = mass x acceleration due to gravity

Mass is the amount of matter in a substance, it exists independently of gravity

In a compound microscope, the objective has a focal length of 1.0 cm, the eyepiece has a focal length of 2.0 cm, and the tube le
expeople1 [14]

Answer:

The  value  is   m \approx   310

Explanation:

From the question we are told that

     The  focal length of the objective is  f_o =  1.0 \ cm

    The  focal length of the eyepiece is  f_e  =  2.0 \  cm

    The  tube length is  L  =  25 \  cm

Generally the magnitude of the overall magnification is mathematically represented as

            m =  m_o  *  m_e

Where  m_o is the objective magnification which is mathematically represented as

        m_o  =  \frac{L}{f_o }

=>      m_o  =  \frac{25}{1 }

=>      m_o  =  25

m_e is the eyepiece magnification which is mathematically evaluated as

     m_e  =  \frac{L }{f_e }

     m_e  =  \frac{25 }{ 2}

      m_e  =  12.5 \  cm

So

    m =  25 * 12.5

     m \approx   310

A cylindrical fishing reel has a mass of 0.7 kg and a radius of 5.24 cm. A friction clutch in the reel exerts a restraining torq
Korolek [52]

Answer:

Explanation:

moment of inertia of reel = 1/2 mr² , m is mass and r is radius of the reel

= .5 x .7 x .0524²

= 96.1 x 10⁻⁵

If force required be F

F  x .0524 - 1.88 is net torque acting on the reel

F  x .0524 - 1.88 = moment of inertia x angular acceleration.

F  x .0524 - 1.88 = 96.1 x 10⁻⁵ x 65.7

F  x .0524 - 1.88 = .063

F  x .0524  = .063 + 1.88

F = 37.08 N

look around you to find an object in motion .describe the objects motion by discussing its position and direction of motion in r
VARVARA [1.3K]
An example you could use for this would be if you threw a pencil across the room 10m away. the pencil would have travelled 10m(N). you could determine the objects speed by using the formula speed=distance/time. you would have had to time how long it took for the pencil to hit the 10m marking and divide 10 by however many seconds it took.
