An object is located 51 millimeters from a diverging lens. The object has a height of 13 millimeters and the image height is 3.5

12345 [234]

You would get 13.7
mi/51mm=3.5mm/13mm
by solving it you will B13.7mm

Fine grains of beach sand are assumed to be spheres of radius 49.8 µm. these grains are made of silicon dioxide which has a dens

PIT_PIT [208]

Answer: $1.3\times10^{-9}kg$

Volume of each grain of sand:

$V=\frac{4}{3}\pi r^3$

radius of the spherical grain is given, $r=49.8\mu m=49.8\times10^{-6} m$

$\Rightarrow V=\frac{4}{3}\times3.14\times(49.8\times10^{-6})^3m^3=5.17\times10^{-13}m^3$

The grains are made up of silicon dioxide.

The density is equal to $D=2600 kg/m^3$

Then, the mass of each grain is given by:

$Mass=Density (D)\times Volume(V)\\ \Rightarrow M=2600 kg/m^3\times5.17\times10^{-13}m^3 =1.3\times10^{-9}kg$

Suppose the green car was traveling at 0 miles the white car was traveling at 70 miles at the red car was trailing at 22 miles w

Elan Coil [88]

Answer:

The white car will cover the most distance every second.

Explanation:

The formula for the uniform speed of an object is given as follows:

$s = vt$

where,

s = distance covered by the object

v = speed of the object

t = time required

Now, if we assume time to be constant at 1 s. Then the distance covered by each car will be directly proportional to the speed of the car. Hence, the car with the greatest speed will travel the greatest distance in 1 second.

We, have:

Speed of white car > Speed of red car > Speed of green car

<u>Therefore, the white car will cover the most distance every second.</u>

When you mix two gases what can you predict about the conservation of volume in this case?

o-na [289]

Amagat's law of additive volumes states that we can simply add up the individual volumes of each gas (provided they are at the same temperature and pressure) to get the total volume of the mixture. Conservation of volume is an acceptable assumption for gases (but not always for liquid mixtures). This works for gases since the molecules are very small and only take up a minimal amount of space in a gas.
