A compound is made up of two or more of atoms that are bonded together with each other via a chemical bonding. It is possible to break the compounds into separate smaller components by the process of chemical reaction. One very simple example of compound is water as it is made of two atoms of hydrogen and one atom of oxygen. Whenever atoms are joined together to create a compound, the atoms definitely loose their individual atomic properties. Other very commonly found compound is carbon dioxide. It is made up of one atom of carbon and two atoms of oxygen.

A child is riding a merry-go-round that is turning at 7.18 rpm. If the child is standing 4.65 m from the center of the merry-go-
iVinArrow [24]

Answer:

B) 3.50 m/s

Explanation:

The linear velocity in a circular motion is defined as:

v=\omega r(1)

The angular frequency (\omega) is defined as 2π times the frequency and r is the radius, that is, the distance from the center of the circular motion.

\omega=2\pi f(2)

Replacing (2) in (1):

v=2\pi fr

We have to convert the frequency to Hz:

7.18rpm*\frac{1Hz}{60rpm}=0.12Hz

Finally, we calculate how fast is the child moving:

v=2\pi(0.12Hz)(4.65m)\\v=3.5\frac{m}{s}

telo118 [61]

Answer:

Acceleration a=0.455m/sec^2

Explanation:

We have given that the force by the motor F=2.51\times 10^3N=2510N

Resistive force by the water F=1.88\times 10^3N=1880N

So net force F_{NET}=2510-1880=630N

Mass of the boat = 1384.1 kg

According to newton's second law F=Ma, here M is mass and a is acceleration

So 630=1384.1\times a

a=0.455m/sec^2

How many LEDs must be combined into one light source to give a total of 3.8 W of visible-light output (comparable to the light o
notka56 [123]

Answer:

This is an incomplete question. The complete question is --

An individual white LED (light-emitting diode) has an efficiency of 20% and uses 1.0 W of electric power.

How many LEDs must be combined into one light source to give a total of 3.8W of visible-light output (comparable to the light output of a 100W incandescent bulb)?

And the answer is --

19 LEDs

Explanation:

The full form of LED is Light emitting diode.

It is given that the efficiency of the LED bulb is 20 %

1 LED uses power = 1 W

So the output power of 1 LED = 0.2 W

We need to find the power required to give a 3.8 W light.

Power required for 3.8 W = Number of LEDs required  =   (total required power  /  power required for 1 LED )

                                                                                         = 3.8 / 0.2

                                                                                         = 19

Therefore, the number of LEDs required is 19.
