Answer:

a) 10^-8 m b) 10^-5 mm c) micrometer

Explanation:

nano means 10^-9

hence 10 nanometers = 10×10^-9 m = 10^-8 meters

millimeters means 10^-3 meters

10^-8m = 10^-5×10^-3m=10^-5 millimeter

micro meter means 10^-6 meters

10^-8m = 10^-2 ×10^-6 m = 10^-2 micrometer = 0.01 micrometer

Answer:

The distance is $2.58\times10^{7}\ m$ .

Explanation:

Given that,

Time $\Delta t = 0.2\ s$

The velocity is no more than a 14 % error in the speed of light.

So,

Velocity $v= c\times 86\%$

We need to calculate the distance

Using formula of speed

$v = \dfrac{d}{t}$

$d = v\times t$

Where, v = speed

d = distance

t = time

Put the value into the formula

$d = 3\times10^{8}\times\dfrac{86}{100}\times0.2$

$d=516\times10^{5}\ m$

We know that,

The one side distance d' is

$d'=\dfrac{d}{2}$

$d'=\dfrac{516\times10^{5}}{2}$

$d'=2.58\times10^{7}\ m$

Hence, The distance is $2.58\times10^{7}\ m$ .

andre [41]

Answer:

Explanation:

Heat capacity = mass x specific heat

heat capacity ∝ mass

∝ volume

heat capacity ∝ volume

H₁ / H₂ = V₁ / V₂

H₁ and H₂ are heat capacity corresponding to volume V₁ and V₂.

312 / 100000 = 1 / V₂

V₂ = 100000 / 312

= 320.51 cubic foot.
