Answer:

d.The wavelength of light and the size of the aperture

Explanation:

The resolution power of an optical system is the smallest distance between two points that the device can distinguish clearly.

It has the following relationship:

$r=\frac{\lambda}{2n}$

where:

r = minimum resolvable distance

n = numerical aperture

$\lambda$ = wavelength of the light used for viewing

From above mathematical equation it is clear that:

Smaller the wavelength better the resolving power
Larger the aperture better the resolution

(Note, that smaller the value of "r" the more finer details of the image visible through the device.)

Henry was giving the school toy for his birthday he can use it to tell how fast someone is moving at the moment in time the toy

pochemuha

Answer:

The toy must calculate the person's speed/velocity

Explanation:

Since the school toy given to Henry can be used to tell how fast someone is moving, the toy must be able to calculate the person's speed/velocity using the average distance covered by the person divided by time taken to cover the distance; average distance ÷ time taken.

The toy must be able to determine the parameters (average distance and time taken) in order to be able to calculate the person's speed/velocity

Select the statements that are TRUE. Electrophilic aromatic substitution reactions have energies of activation that are very low

NikAS [45]

Answer:

Addition reactions with benzenes lead to the loss of aromaticity.

Benzene and its derivatives undergo a type of substitution reaction in which a hydrogen atom is replaced by a substituent, but the stable aromatic benzene ring is regenerated at the end of the mechanism.

Benzene and its derivatives tend to undergo electrophilic aromatic substitution reactions.

Two liquids, A and B, have equal masses and equal initial temperatures. Each is heated for the same length of time over identica

DochEvi [55]

Answer:

So the specific heat of the liquid B is greater than that of A.

Explanation:

Liquid A is hotter than the liquid B after both the liquids are heated identically for the same duration of time from the same initial temperature then according to heat equation,

$Q=m.c.\Delta T$

where:

m = mass of the body

c = specific heat of the body

$\Delta T=$ change in temperature of the body

The identical heat source supplies the heat for the same amount of time then the quantity of heat supplied is also equal.

So for constant heat, constant mass the temperature change is inversely proportional to the specific of heat of the liquid.

$\Delta T=\frac{Q}{m} \times \frac{1}{c}$

$\Delta T\propto\frac{1}{c}$

So the specific heat of the liquid B is greater than that of A.

Which of the following provides evidence that earth is rotating? The sun rises and sets, The plane of a foucault pendulum appear

bagirrra123 [75]

The answer would be 'The plane of a Foucault pendulum appears to shift its orientation' because it is an experiment to demonstrate the rotation of the earth.

Hope this helps.
