Vikki [24]3 years ago

5 0

Explanation:

given

mass (m) = 1200 kg

Acceleration (a) = 3 m/s²

Force (F) = ?

We know

F = m * a

= 1200 * 3

= 3600 Newton

The force acting on the car is 3600 Newton.

Hope it helps :)

A solid cube of aluminum (density of 2.7 g/cm³) has a volume of 0.9 cm³. how many atoms are contained in the cube?

Reika [66]

Answer:

$0.542*10^{23}\ Aluminum\ Atoms$

Explanation:

$We\ are\ given:\\Density\ of\ aluminum=2.7\ g/cm^3\\Volume\ of\ aluminum-cube=0.9\ cm^3\\Hence,\\As\ we\ know\ that,\\Density=\frac{Mass}{Volume}\\Mass=Density*Volume\\Hence,\ here,\\Mass\ of\ the\ solid\ iron\ cube=2.7*0.9=2.43\ g\\Now,\\We\ also\ know\ that,\\Gram\ Atomic\ mass\ of\ Aluminum = 26.98 \approx 27\ g\\Hence,\\No.\ of\ particles=\frac{Mass}{GAM}*Avagadro's Constant\\Hence,\ here\\No.\ of\ Aluminum\ atoms=\frac{2.43}{27}*6.022*10^{23} \approx 0.542*10^{23}\ Aluminum\ Atoms$

In Young’s double-slit experiment using monochromatic light, the interference pattern consists of a central _____.

NNADVOKAT [17]

Answer:

In Young’s double-slit experiment using monochromatic light, the interference pattern consists of a central <u>MAXIMUM</u>.

Explanation:

In Young's double slit method of experiment we know that on the screen we have light of monochromatic source.

Due to this double slit system when light reaches to the screen there exist a finite path difference on the screen and which will create phase difference between two light reaches on the screen

It is given as

$\Delta \phi = \frac{2\pi}{\lambda}$ (Path difference)

so here if path difference is zero due to two slits at the center of the screen

Then in that case

$\Delta \phi = \frac{2\pi}{\lambda}(0) = 0$

so we will have maximum intensity at the center of the screen when light will reach at the center of the screen.

The total sum of atoms in an object.

Darina [25.2K]

Answer:

Mass

Explanation:

The total sum of atoms in an object is the mass of the object. There are several ways to quantify the number of atoms in a substance.

In chemical calculations, the number of moles is a good representation of the number of atoms contained in a body.
Mass is the amount of substances a body has.
If we can sum up all the atoms in a substance, one will arrive at the mass of the substance
