Answer:
1.5 times
Explanation:
= depth of the diver initially = 5 m
= density of seawater = 1030 kg m⁻³
= Initial pressure at the depth
= final pressure after rising = 101325 Pa
Initial pressure at the depth is given as
= Initial volume at the depth
= Final volume after rising
Since the temperature remains constant, we have
In a gear train with two gears, the gear ratio is defined as follows
where
is the angular velocity of the input gear while
is the angular velocity of the output gear.
This can be rewritten as a function of the number of teeth of the gears. In fact, the angular velocity of a gear is inversely proportional to the radius r of the gear:
But the radius is proportional to the number of teeth N of the gear. Therefore we can rewrite the gear ratio also as
Is the production of electricity by magnetic field.
There are two types of generator which is <u>D</u><u>.</u><u>C</u><u> </u>generator . And A.C <em>g</em><em>e</em><em>n</em><em>e</em><em>r</em><em>a</em><em>t</em><em>o</em><em>r</em>
A.C gen consist of rectangular coil,brushes and permanent magnet
According to the external force mechanical energy used to rotate coil, due to magnetic flux produced by permanent magnet create induced current, this is to according to flemmings right hand rule of electromagnetic induction the rotating coil will produce current
I hope that will help.
<u>Answer:</u>
The correct answer option is D. The distance between the planet and the Sun changes as the planet orbits the sun.
<u>Explanation:</u>
Kepler’s laws of planetary motion, derived by the German astronomer Johannes Kepler, are the laws of physics that describe the motions of the planets in the solar system.
According to the Kepler's first law of planetary motion: the path on which the planets orbit around the sun is elliptical in shape, with the center of the sun at one focus.
Therefore, the distance between the Sun and the planets vary as the planet orbit around the sun.
