Jovian planets are also known as gas giants and are the four outer planets Jupiter, Saturn, Uranus and Neptune. Uranus stands out from this group because of the tilt of its axis. Uranus is tilted on its side. Scientists speculate that this tilt may be as a result of a collision with a large body just after the planet was formed. Uranus is tilted 98 degrees compared to earth's 23 degrees.
Answer:
Similarities between magnetic fields and electric fields: ... Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract. Electric field points in the direction of the force experienced by a positive charge ...
Explanation:

Here is another thing from the same website just not shortened:
Similarities between magnetic fields and electric fields:
- Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges).
- Like poles repel; unlike poles attract
- Electric field points in the direction of the force experienced by a positive charge. Magnetic field points in the direction of the force experienced by a north pole.
Differences between magnetic fields and electric fields:
- Positive and negative charges can exist separately. North and south poles always come together. Single magnetic poles, known as magnetic monopoles, have been proposed theoretically, but a magnetic monopole has never been observed.
- Electric field lines have definite starting and ending points. Magnetic field lines are continuous loops. Outside a magnet the field is directed from the north pole to the south pole. Inside a magnet the field runs from south to north.
To solve this problem we will apply the ideal gas equations for which the product of pressure and volume is defined, as the equivalent between the ideal gas constant by the amount of matter and the temperature, mathematically this equation is described as
Here,
P = Pressure
V = Volume
R = Ideal gas Constant
T = Temperature
n = Number of molecules
The pressure is in atmospheres, and considering the units of the other values we have finally that,
Replacing,
Multiplying the number of moles by Avogadro's number we have,
Therefore the number of ozone molecules in the Earth's ozone layer are
<h2>
<u>Given</u>:</h2>
Horizontal distance between two boats = x = 14 m
One boat is at trough, the other is at crest.
As there is no crests between them meaning the boat are next to each other.
Wavelength is the distance between two consecutive crests/troughs = w
The distance between a crest and a trough next to it = w/2
Complete cycles = c = 5
Time taken for c cycles = t = 15 s
Vertical distance between two boats = y = 2.4 m
<h2>
<u>To find</u>:</h2>
wavelength = w = 2x = 28 m
Amplitude = A = Displacement from mean to extreme position = y/2 = 1.2 m
Time period for one cycle = T = t/c = 15/5 = 3 s/cycle
frequency = 1/T = 1/3 = 0.33 hertz
speed = wavelength/Period = w/T = 28/3 = 9.33 m/s
Physics contributes to the technological infrastructure and provides trained personnel need to take advantage of scientific advances and discoveries.
Physics is an important element in the education of chemists, engineers and computer scientists as well as practitioners of the other physical and biomedical sciences .
