Answer:

4.05*10^7m/s^2

Explanation:

v1=0

v2=90*1000*3600=324000000

t=8

a= (v1 -v2)/t

P.T.Vs,

a=(0-324000000)/8 90*1000 ,90000*3600

as they r talking about km per hour so kilo is = 1000 and hour=min*sec

1hour-60min and 1min=60sec so 60*60=3600 so simply we have to multiply 90 with 1000 and then with 3600.formula a=(v1 -v2)/t

a=40500000m/s^2 or

a=4.05*10^7m/s^2

A distance of 200 ft must be taped in a manner to ensure a standard deviation smaller than ± 0.04 ft. What must be the standard

Nutka1998 [239]

Answer:

The error in tapping is ±0.02828 ft.

Explanation:

Given that,

Distance = 200 ft

Standard deviation = ±0.04 ft

Length = 100 ft

We need to calculate the number of observation

Using formula of number of observation

$n=\dfrac{\text{total distance}}{\text{deviation per tape length}}$

Put the value into the formula

$n=\dfrac{200}{100}$

$n=2$

We need to calculate the error in tapping

Using formula of error

$E_{series}=\pm E\sqrt{n}$

$E=\dfrac{E_{series}}{\sqrt{n}}$

Put the value into the formula

$E=\dfrac{0.04}{\sqrt{2}}$

$E=\pm 0.02828\ ft$

Hence, The error in tapping is ±0.02828 ft.

Speed of violet light in vacuum

sukhopar [10]

Answer:

Explanation: Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index of 1.3; see Figure 2) and 200,000 kilometers per second in glass (refractive index of 1.5).

A man pushes a grand piano along a level stage with 380 N force that is 15° above the horizontal. The piano

Andreyy89

Answer:1688.393 joules

Explanation:

force along 15°(f) =380N

Φ=15°

Distance=4.6m

Time=9.5s

work=horizontal component force(F) x distance

Horizontal component force=f x cosΦ

Horizontal component of force=380 x cos15

Horizontal component of force =380x0.9659

Horizontal component of force=367.042N

Work=force horizontal component x distance

Work=367.042 x 4.6

Work=1688.393

Work=1688.393 joules
