What are the two segments of a comet?
Katyanochek1 [597]
Two segments of a comet are head and tail.

Head is main part of comet. Depending on how comet was created head can be made out of metal (such as iron) or stone. Also, head contains a lot of dust and water ice. When comet comes closer to Sun it's surface warms and ice starts to melt. Due to low pressure in space it almost instantly evaporates creating water vapour. This vapour causes the particles of dust to raise above surface of head and to fall back of the head. 

Tail is most viewed part of a comet. It best something that we can see with naked eye and that helps us to distinguish comet and all other celestial bodies. Tail is made out of two other tails. First is dust tail. It is created when dust particles rise from head of a comet and fall behing it. Gravity of a comet causes for these particles to follow head. Dust tail is always located opposite to direction of movement. Second tail is ionic tail. When solar particles (such as solar wind) hit comet they ionize atoms and molecules. This causes them to glow and produce light which we can see. Ionic tail is always opposite to direction in which Sun is located. When comet is far from Sun dust and ionic tail lay in same position. When comet is close to Sun dust and ionic tail not always lay in same position.

An AC voltage source has an output of ∆V = 160.0 sin(495t) Volts. Calculate the RMS voltage. Tries 0/20 What is the frequency of
kupik [55]

Answer:

RMS voltage is 113.1370 V

frequency is 780.685 Hz

voltage is −158.66942 V

maximum current is  2.9739 A

Explanation:

Given data

∆V = 160.0 sin(495t) Volts

so Vmax = 160

and angular frequency = 495

time t = 1/106 s

resistor R = 53.8 Ω

to find out

RMS voltage and frequency of the source and  voltage  and maximum current

solution

we know voltage equation = Vmax sin ωt

here Vmax is 160 as given equation in question

so RMS will be Vmax / √2

RMS voltage = 160/ √2

RMS voltage is 113.1370 V

and frequency = angular frequency / 2π

so frequency = 497 / 2π

frequency is 780.685 Hz

voltage at time (1/106) s

V(t) = 160.0 sin(495/ 108)

voltage = −158.66942 V

so current from ohm law at resistor R 53.8 Ω

maximum current = voltage max / resistor

maximum current =  160 / 53.8

maximum current =  2.9739 A

When you lift an object, you add the energy of lifting to the object.<br> Tor F
PtichkaEL [24]

It's true, when we lift an object we add energy to it.

because, when we lift an object by applying force , the object attains a height and hence the energy gets stored in it, in the form gravitational potential energy .
