Keisha drew a diagram to compare two of the fundamental forces. A venn diagram of 2 intersecting circles with the left circle la

beled weak nuclear force and the right circle labeled strong nuclear force. There is an X in the weak nuclear force circle. There is a Z in the strong nuclear force circle. There is a Y in the intersecting area. Which labels belong in the areas marked X, Y, and Z? X: Always attractive Y: Very small range Z: Attractive and repulsive X: Attractive and repulsive Y: Very small range Z: Always attractive X: Very small range Y: Attractive or repulsive Z: Infinite range X: Infinite range Y: Attractive or repulsive Z: Very small range

(a) Find the voltage near a 10.0 cm diameter metal sphere that has 8.00 C of excess positive charge on it. (b) What is unreasona
antoniya [11.8K]

Answer:

Part a)

V = 7.2 \times 10^{11} Volts

Part b)

this is a large potential which can not be possible because at this high potential the air will break down and the charge on the sphere will decrease.

Part C)

here we can assume the sphere is placed at vacuum so that there is no break down of air.

Explanation:

Part a)

As we know that the potential near the surface of metal sphere is given by the equation

V = \frac{kQ}{R}

here we have

Q = 8 C

R = 10.0 cm

now we have

V = \frac{(9\times 10^9)(8 C)}{0.10}

V = 7.2 \times 10^{11} Volts

Part b)

this is a large potential which can not be possible because at this high potential the air will break down and the charge on the sphere will decrease.

Part C)

here we can assume the sphere is placed at vacuum so that there is no break down of air.

A 4-watt night light is left on for 8 hours each night. How much work dies it do per night
ki77a [65]

The light bulb doesn't do any "work" ... it doesn't exert force,
or maintain a force through a distance.  It does, however,
dissipate energy, in the form of heat and light.

The quantity of energy that it dissipates is ...

         (4 watts) x (8 hours) x (3600 sec/hour) x (1 joule/watt-sec)

     =  (4 x 8 x 3600) joules  =  115,200 joules .

How did researchers go about investigating trans-sonic flight
Annette [7]

<span>A wind tunnel is a traditional tool used for trans-sonic flight research. But, during those days, it’s not exact and consistent to use for aircraft flow conditions. The reason is that wind tunnel models will be visible to airflow that produces shock waves. So the U.S and Britain develop an instrument to get data and record flow conditions for a specified speed, these are the specialized research airplanes.</span>

If the primary coil of a transformer has 200 turns and is supplied with 120 v ac power, how many turns must the secondary coil h
Oduvanchick [21]
The ratio of the turns to the voltage should be equal
i.e: 200/120 = t/12
so the secondary coil should have 20 turns
