An archer aims his arrow directly at an orange hanging on an orange tree. At the moment he releases the arrow, the orange drops
Elena L [17]

Answer:

Yes it would

Explanation:

As the arrow and the orange are in the same position initially, vertically speaking. They are also subjected to the same gravitational acceleration g only in the vertical direction. They also start their motion at the same time. So their equation of motion can be written as

y = h + gt^2/2

Where h is the initial height of both of them. Since their g, h, and t are the same, their vertical position must be the same at the same time. As the arrows progress horizontally, it would hit the orange.

Batteries are usually identified by their voltage.
Fynjy0 [20]

Answer:

Explanation:

Given parameters:

Electrical energy  = 18J

Quantity of charge Q = 12C

Unknown:

Voltage  = ?

Solution:

The expression of electrical potential energy is given as:

      Electrical potential energy  = \frac{1}{2} c v²

c is the quantity of charge

v is the voltage

           18  =  \frac{1}{2}  x 12 x v²  

           18 = 6v²  

              v² = 3  

               v = 1.7v

How are parallel circuits used in homes?
zhannawk [14.2K]
Every single thing in your home that's plugged into a wall outlet or works with a switch on the wall . . . every lamp, ceiling light, room fan, computer, microwave, stove, hair dryer, coffee pot, toaster, slow cooker, TV, home entertainment system, printer, wifi router, cordless phone, phone charger, and clock radio ...  they're ALL in parallel.

<u>And</u> chances are that everything in your house is also in parallel with everything in the houses of a few of your neighbors on each side of you.

THAT's how parallel circuits are used in residential areas.
