A battery is the power source for what type of current

patriot [66]

Answer: DC Current

Explanation:

Battery is a source of constant potential difference and it will create a constant voltage across any conductor

due to this constant voltage difference the current in this conductor will remain constant

So here since the voltage across the conductor is constant so we can say that current in the conductor will remain constant and hence this is known as DC current.

While for variable current in direction and magnitude is to be obtained only when the conductor is connected with AC voltage source as we know that AC voltage is variable with magnitude and direction both

A battery is the power source for DC type of current. A battery is a source of constant potential difference that produces a constant current unlike in AC source where the voltage and hence the current changes its polarity continuously.Hence, the current produced by battery is direct current and not Alternating current.

Hope this helps........ Stay safe and have a Merry Christmas!!!!!! :D

put the following in order of a full lunar month: full moon, new moon, 1st quarter, waxing gibbous, waning gibbous, waxing cresc

ASHA 777 [7]

The same cycle of phases repeats over and over and over and over and over again, so I could start the list with whatever phase I want, and build the list until I get to the same phase I started with.

But the cultures that track their months by the phases of the Moon (traditional Muslim, traditional Jewish, traditional Chinese) all start the new month with the New Moon, so I guess I'll start my list there too.

-- New Moon

-- Waxing Crescent

-- First Quarter

-- Waxing Gibbous

-- Full Moon

-- Waning Gibbous

-- Third Quarter

-- Waning Crescent

-- next New Moon

A client with a head injury is being monitored for increased intracranial pressure (ICP). The client's blood pressure is 90/60 m

artcher [175]

Answer:

$CPP=52mm \ Hg$

Explanation:

Cerebral Perfusion Pressure is obtained by subtracting IntraCranial Pressure(ICP) from the Mean Arterial Pressure(MAP). Adequate cerebral perfusion requires a minimum goal of $70mm \ Hg$ . MAP is obtained using the formula:-

$MAP=\frac{(diastolic \ blood \ pressure\times2)+\ systolic \ blood \ pressure)}{3}\\\\MAP=\frac{2\times60+90}{3}\\\\MAP=70mm \ Hg\\CPP=MAP-ICP\\CPP=70-18\\CPP=52mm \ Hg$

A stone is dropped from the edge of the roof. (A) how long does it take to fall 4.9m

zvonat [6]

Since the stone is being dropped, you know that it is in free fall. That means you can use your kinematics equations, since acceleration is free fall is a constant 9.8 m/s^2 down.

Looking through the kinematics equations, you want to use one that lets you find t, time, while using variables that we already know the values of. Notice that in the equation:
$x_f = x_{0} + v_0 t + \frac{1}{2} a t^2$

Say that the rock starts at point x=0. That means the initial value of x, the position, is $x_0$ = 0m, and the final position is $x_f$ = -4.9m. We are also told that the initial velocity, $v_0$ = 0, assuming it's being dropped from rest, and a = -9.8 m/s^2. Plug these numbers in and solve for t:
$x_f = x_0 + v_0 t + \frac{1}{2} a t^2\\ x_f - x_0 = \frac{1}{2} a t^2\\ -4.9 - 0 = \frac{1}{2} a t^2\\ -9.8 = a t^2\\ -9.8 = -9.8 t^2\\ 1 = t^2\\ t = 1 \: second$

Answer: t = 1 s
