You are asked to calculate how long a new battery will last on a flashlight when the flashlight is turned on. how long should yo
valina [46]

Answer:

           Depends on the capacity of battery. Mostly our phones flashlight can be used up to 8 to 10hrs continuosly

Explanation:

Capacity of the battery is level to which battery is charged, &  amount of current drawn by the flashlight, you can calculate the answer yourself if u know the capacity of that light.

Moreover you can calculate this by using equation,

         E =Pt

So, for time

      t=E/P

Batteries are rated in Amp hours, like 10 amp hours will supply us 1 amp for 10 hours

2 amps will give us 5 hours

The usual electrosurgical apparatus contains an oscillator that produces a high-frequency current of frequencies above 500,000 c
AURORKA [14]

Answer:

B Electrocoagulation.

It is a process that involves the use of high frequency current to cause coagulation usually of protiens in tissues and also the destruction of abnormal tissues making use of the heat generated by the electric current. This tissue could be a tumor or some other kind of lesion.

Explanation:

The passage of electric current through the electrode (second electrode that has been sterilized) in contact with the tissue causes the molecules within them to vibrate. This leads to a sharp increase in the temperature of the tissue due to the heat generated by the electric current. This is what causes the coagulation of the proteins within the tissue and also burns the tissue thereby effectively destroying it.

Electrocoagulation also called electrocautery, electrofulguration, and fulguration.

The certain forest moon travels in an approximately circular orbit of radius
Alinara [238K]

Answer:

Mass of Exoplanet =  0.58 kg

Explanation:

First, we will calculate the speed of the forest moon:

speed = v = \frac{Circumference}{time}\\

circumference = 2πr = 2π(14441566 m) = 90739035.3 m

time = 6 days 10 hr = (6 days)(24 h/1 day)(3600 s/1 h) + (10 h)(3600 s/1 h)

time = 554400 s

Therefore,

v = \frac{90739035.3\ m}{554400\ s}\\\\v =  163.67\ m/s

We know that the centripetal force on forest moon will be equal to the gravitational force given by Newton's Gravitational Law, as follows:

Centripetal\ Force = Gravitational\ Force\\\frac{m_{moon}v^2}{r} = \frac{Gm_{moon}m_{exoplanet}}{r^2}\\\\m_{exoplanet} = \frac{v^2r}{G}\\\\m_{exoplanet} = \frac{(163.67\ m/s)^2(14441566)}{6.67\ x\ 10^{-11}\ N.m^2/kg^2}

<u>Mass of Exoplanet =  0.58 kg</u>
