KE=1/2 m v^2
KE= .5 x 2kg x 15m/s to the 2nd power
KE=225 km/s

Answer:

Kinetic energy = 225 J

Explanation:

As we know that kinetic energy is given as

KE = \frac{1}{2}mv^2

now here we know that

m = 2 kg

v = 15 m/s

now from above formula we know

KE = \frac{1}{2}(2)(15)^2

now we have

KE = 225 J

so kinetic energy of the moving ball is 225 J

Answer:

magnetic flux linkage includes number of turns, N while magnetic flux has no N

Since number of turns are not significant to units, they become similar.

A bicycile traves with an average velocty 15km/h north for 20min what is his displasment​
Mila [183]

Answer:

5000 m equivalent to 5 Km

Explanation:

Average velocity =\frac{Displacement}{Time}

so, Displacement =Average velocity × time

We should convert Km/h to m/s so Km/h ⇒ \frac{1000}{60*60} m/s, also convert time to second so, 20min ⇒(20* 60)seconds

Displacement = (15 ×\frac{1000}{60*60}) × (20×60) =5000m OR 5Km

What is the sound intensity level in decibels? Use the usual reference level of I0 = 1.0×10−12 W/m2.
jek_recluse [69]

Answer:

L = 130 decibels

Explanation:

The computation of the sound intensity level in decibels is shown below:

According to the question, data provided is as follows

I = sound intensity = 10 W/m^2

I0 = reference level = 1 \times 10-12 W/m^2

Now

Intensity level ( or Loudness)is

L = log10 \frac{I}{10}

L = log10 \frac{10}{1\times 10^{-12}}

L = log10 \times 1013

= 13 \times 1 ( log10(10) = 1)

Therefore  

L = 13 bel

And as we know that

1 bel = 10 decibels

So,

The  Sound intensity level is

L = 130 decibels
