The planets from strongest magnetic field to weakest magnetic field is Jupiter > Earth > Venus.

Magnetic fields are generated by the movement of magnetic material located in side the planet, usually at the core.

Jupiter, the biggest planet in our planetary system, likewise has the biggest magnetic field, producing a magnetosphere bigger than the Sun. It`s magnetic field is created by its fast rotation of 9.8 Earth hours. Dissimilar to Earth, Jupiter`s magnetic field is not produced by its core yet by interaction in its external core, which comprises of liquid metallic hydrogen.

Earth's magnetic field is produced by liquid metal at the center and Earth's fast pivot of 24 hours creates enough movement of the liquid to animate a magnetic field. While Venus does not have a magnetic field, likely on account of it's slow rate at around 243 Earth days, it's as yet shielded from sun oriented breezes utilizing an alternate kind of magnetism.

Therefore, the Jupiter have magnetic fields much stronger than that of the Earth and Venus.

a gym consists of a rectangular region with a semi-circle on each end. if the perimeter of the room is to be a 200 m running tra

Nikolay [14]

The dimensions of the rectangle are:

l = 50 m

b = $100/\pi$ m

<h3>What is a perimeter in math?</h3>

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides.

<h3>How do we find a perimeter of a rectangle?</h3>

The perimeter of a rectangle,denoted by P is given by the formula, P=2l+2b, where l is the length and b is the breadth of the rectangle.

<h3>Given:</h3>

As per the question:

Perimeter of the room is given as P = 200 m

The region is rectangular having a semicircle at each end.

Now,

Let 'l' be the length of the rectangle, 'b' be its breadth and 'r' be the radius of the semi-circle at each end.

Then, Area of the given rectangle, A = lb

Perimeter of the room, P is = $\pi r+l+\pi r+l=2\pi r+2l=\pi b+2l$

Therefore, $\pi b+2l=200$

$b=(200-2l)/\pi$

Now,

Area, A = $l(200-2l)/\pi=(200l-2l^{2} )/\pi$

Now, differentiate A w.r.t l:

Again differentiating w.r.t 'l', we get:

$d^{2} A/dl^{2} =-4l/\pi$ < 0

Thus we get maximum are when $dA/dl=0$

Therefore,

$(200-4l)/\pi=0$

l = 50 m

Now, from

$\pi b+2l=200$

$\pi b=200-2*50$

$b=100/\pi$

$r=b/2=50/\pi$

Our eyes can see light with an angular resolution of about 1’—equivalent to about a third of a millimeter at arm’s length. Suppo

olya-2409 [2.1K]

Answer:

We would not be able to make our way around the earth's surface, to read, to sculpt or to create technology because we cannot see!

Explanation:

The minimum angular separation that can be distinguished by an eye gives the angular resolution of the eye.

Given that the Angular resolution with infrared radiation is = $1.0^0$ equal to $60'$

This resolution is very much greater than that of the eye $(1')$

The angular resolution that our eyes can see is about $\frac{1}{3}mm$ at arms length

Angular resolution of infrared = $\frac{1}{3} * 60 = 20mm$ at arms length

We therefore cannot read, sculpt or create technology because we cannot see.

A cylinder with a piston contains 0.250 mol of oxygen at2.40x105 Pa and 355 K. The oxygen may be treated as an ideal gas.The gas

Nikitich [7]

Answer:

= 285 Joules

Explanation:

a) answer can be found out in attachment

(b) The temperature for the isothermal compression is the same as the temp at the end of the isobaric expansion. Since pressure is held constant but volume doubles, we use the ideal gas law:

p V = nR T to see that the temperature also doubles.

.So... temp for isothermal compression = 355×2 = 710 K

.(c) The max pressure occurs at the top point. At this point, the volume is back to the original value but the temperature is twice the original value. So the pressure at this point is twice the original, or

max pressure = 2×240000 Pa = 480000 Pa = 4.80 x 10^5 Pa

(d) total work done by the piston = workdone during isothermal compression - work done during expansion =

= nRT ln(V initial / V final)-p (V initial - V final)

= nRT ln(2) - nR(T final - T initial)

= 0.250× 8.314 ×710×ln(2)-0.250×8.314× (710 - 355)

= 285 Joules
