Answer:

Visible waves can be seen by people.

Explanation:

Electromagnetic waves comprises of different kind of waves. It consists of cosmic waves, x-rays waves, gamma waves, ultra violet waves, visible waves, infrared waves, microwaves. Among these waves, depending upon the wavelength of each kind of waves, it is visible and invisible to naked eyes. Thus, visible waves are the one which can be seen by people in naked eyes. As the wavelength of these waves are in comparable to the eye sight, so it can be seen by people.

You're having a hard time pushing a refrigerator across the kitchen floor. The force of your own push is 993 N. The force of fri
Helen [10]

Answer:

The acceleration of the refrigerator is a= 0.056 ms^{-2}

Explanation:

The expression of the equation of the net force acting on the refrigerator is as follows;

F-f= ma

Here, F is the applied force, f is the force of friction, m is the mass and a is the acceleration.

It is given in the problem that you're having a hard time pushing a refrigerator having mass 355 kg across the kitchen floor. The force of your own push is 993 N. The force of friction opposing your own push is 973 N.

Put F= 993, f= 973 N and m = 355 kg in the above expression of the equation to calculate the acceleration of the refrigerator.

993 - 973 = (355)a

20 = 355 a

a= 0.056 ms^{-2}

Therefore, the acceleration of the refrigerator is a= 0.056 ms^{-2}.

What specific structures are in electroreceptors?
Slav-nsk [51]
Electroreception is limited to aquatic environments because on here is the resistivity of the medium is low enough for electric currents to be generated as the result of electric fields of biological origin.  In air, the resistivity of the environment is so high that electric fields from biological sources do not generate a significant electric current.  Electroreceptor are found in a number of species of fish,  and in at least one species of mammal,  the Duck-Billed platypus.

A grandfather clock depends on the period of a pendulum to keep correct time.(ii) Suppose a grandfather clock is calibrated corr
ANEK [815]

The grandfather clock will now run slow (Option A).

<h3>What is Time Period of an oscillation?</h3>
  • The time period of an oscillation refers to the time taken by an object to complete one oscillation.
  • It is the inverse of frequency of oscillation; denoted by "T".

Now,

  • \sqrt{\frac{L}{g}}, where L is the length and g is the gravitational constant, is the formula for a pendulum's period.
  • The period will increase as one climbs a very tall mountain because g will slightly decrease.
  • Due to this and the previous issue, the clock runs slowly and it seems that one second is longer than it actually is.

Hence, the grandfather clock will now run slow (Option A).

A ray of light traveling in water (n = 1.33) is incident at the flat surface of a block of glass (n = 1.60). If the incident ray
mel-nik [20]

Answer:

45.19^{\circ}

Explanation:

We are given that

n_1=1.33

n_2=1.6

\theta_1=58.6^{\circ}

We have to find the angle of refraction.

By Snell's law

n_1sin\theta_1=n_2sin\theta_2

Substitute the values

1.33sin58.6=1.6sin\theta_2

sin\theta_2=\frac{1.33sin58.6}{1.6}

sin\theta_2=0.7095

\theta_2=sin^{-1}(0.7095)=45.19^{\circ}

Hence, the angle mad by refracted ray in to the glass with normal=45.19^{\circ}

Why do the lights in your home come on almost instantaneously when you turn on the switch?
arlik [135]

Answer:

here you go

Explanation:

Why do your lights actually come on almost instantaneously? ... Wiring the house in parallel does not make a difference – there is no current flowing through the light bulb when the switch is off no matter how the house is wired. If there were a current already, the light would be on!
