The  "El-nino  current  is  awarm  current  that  periodically  flows  southward  along  the  coast  of Ecuador  and  Peru.  El-nino  start out  from  the  central  and  east  central of  the   pacific,   which  include  pacific  coast  of  this south  America.  this ocean    event  is  associated with  fluctuation of inter  tropical  surface  pressure  pattern and  circulation  in  the  ocean.

Which of these instruments is listed with the wrong type of lens that it uses?
VikaD [51]

The wrong type of lens-Microscope, concave

Explanation:

A microscope Basically  uses t<u>wo convex lenses to magnify an object, or specimen.</u>

There are  2 lenses in a microscope

  1. <u>Object Lens:</u>The lens that is closer to the object
  2. <u>Eyepiece:</u>The lens that is closer to the eye

Both the object lens and the  eyepiece, is a convex lens.

What is the passenger's apparent weight at t=1.0s?
Fittoniya [83]

Answer:

For the complete question provided in explanation, if the elevator moves upward, then the apparent weight will be 1035 N. While for downward motion the apparent weight will be 435 N.

Explanation:

The question is incomplete. The complete question contains a velocity graph provided in the attachment. This is the velocity graph for an elevator having a passenger of 75 kg.

From the slope of graph it is clear that acceleration at t = 1 sec is given as:

Acceleration = a = (4-0)m/s / (1-0)s = 4 m/s^2

Now, there are two cases:

1- Elevator moving up

2- Elevator moving down

For upward motion:

Apparent Weight =  m(g + a)

Apparent Weight = (75 kg)(9.8 + 4)m/s^2

<u>Apparent Weight = 1035 N</u>

For downward motion:

Apparent Weight =  m(g - a)

Apparent Weight = (75 kg)(9.8 - 4)m/s^2

<u>Apparent Weight = 435 N</u>

Two cylindrical resistors are made of the same material and have the same resistance. The resistors, R1 and R2, have different r
Paladinen [302]

Answer:

Option d is correct.

Explanation:

We know , resistance of a body is directly proportional to its length and inversely proportional to its area.

R=\dfrac{\rho\ L}{A}=\dfrac{\rho\ L}{\pi r^2}      ( Here, \rho is constant dependent on object material )

Writing R_1 \ and\ R_2 also :

R_1=\dfrac{\rho\ L_1}{\pi r_1^2}\ , \  R_2=\dfrac{\rho\ L_2}{\pi r_2^2}      ( since they are of same material therefore, \rho is same.)

Now , if r_2=2r_1 \ and \ 4L_1=L_2.

Then R_1=R_2

Therefore, option d. is correct.

Hence, this is the required solution.

If you double the wavelength, the electromagnetic radiation energy will double. The energy of the electromagnetic radiation will
Sedbober [7]

Answer:

It's energy will double.

Explanation:

This is because energy, E, is related to frequency, f, by:

E = hf

Where h = Planck's constant

So, double frequency will be 2f

=> E(2f) = 2hf = 2E.

Hence, energy is doubled.
