What would the American flag look like under a blue light?
nadezda [96]

Answer:

The flag will appear to be black.

Explanation:

This is because red is the only brighter color in the American flag, so when a blue light is shined, the red turns dark and then the flag looks just blank and black.

A box is pulled with a horizontal force of 500N and moves 5m what is work done
dalvyx [7]
The answer to the question is shown below:

We all know that formula for solving work done is the force multiplied by distance covered:
Work done = Force x distance
Distance = 5m
Force = 500 N
Work done = 500 N * 5m
Work done = 2500 J

A 2kg box is pushed along a flat frictionless surface with an applied force of 53.91newton j+19.62 j were j is horizontal and j
tamaranim1 [39]

Since the box doesn't move vertically at all, no work is done by the vertical component of the force.

If 53.91 Newtons is the horizontal component of the force (very unclear in the question), then the work done is

<u>Work = (force) x (distance)</u>

Work = (53.91 N) x (10 m)

<em>Work = 539.1 Joules</em>

<u>Power = (work done) / (time to do the work)</u>

Power = (539.1 joules) / (90 sec)

Power = (539.1/90) (joule/sec)

<em>Power = 5.99 watts</em>

=====================================

Note:  If the mass of the box is only 2 kg, and you push it along the surface with a constant force of 53⁺ Newtons, and the surface really is frictionless, then that box is gonna cover a WHOOOOOLE LOT more than 10 meters in 90 seconds.  I get 109,168 meters !

A standard biological microscope is required to have a magnification of 200Ã. what is the focal length of the objective?
NISA [10]

Answer:

The focal length of the objective is L/20.

Explanation:

Given that,

Magnification of the standard biological microscope, m = 200

Let the magnification of the eyepiece is, m_e=10

Let m_o is the magnification of objective lens. The formula of the magnification is given by :

M=m_o\times m_e\\\\200=m_o\times 10\\\\m_o=20

The formula of the magnification is given by :

M=\dfrac{L}{f_o}m_e

L is length of microscope

f_o is focal length of the objective

f_o=\dfrac{Lm_e}{M}\\\\f_o=\dfrac{10L}{200}\\\\f_o=\dfrac{L}{20}

So, the focal length of the objective is L/20.
