The attractive force that acts between all objects is the

1 answer:

4 0

The correct answer is: "Gravitational force". Therefore, the definition is: "The attractive force that acts between all objects is the gravitational force".

Isaac Newton (Who was a physicist, mathematician, philosopher and inventor) was the one who proposed "The law of universal gravitation", which states that the force of gravity is proportional to the product of two masses and inversely proportional to the square of the distance between its centers of mass.

Which of the following statements about motion are true? Select all that apply.

Blababa [14]

Answer:

A, C, D

Explanation:

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

and according to Newton's 4th law: An object that is at rest will stay at rest unless a force acts upon it. An object that is in motion will not change its velocity unless a force acts upon it.

Which is the destructive interference formula for diffraction grating problems? dsin = dcos = dcos = n dsin = n.

shusha [124]

The destructive interference formula for diffraction grating problems is $d sin \theta = (n+\frac{1}{2})\lambda$ .

<h3>What is the definition of destructive interference?</h3>

Destructive interference happens when the maxima of two waves are 180° out of phase a positive displacement of one wave is canceled exactly by a negative displacement of the other wave.

The formula for brighter patches resulting from constructive interference and darker patches resulting from destructive interference in a diffraction grating is:

$\rm d sin \theta = n \lambda$

The grating spacing is denoted by d, the angle of light is denoted by a the fringe order is denoted by n, and the wavelength is denoted by $\rm \lambda$ .

The destructive interference formula is now based on the fact that destructive interference occurs between the fringes.

Hence the destructive interference formula for diffraction grating problems is $d sin \theta = (n+\frac{1}{2})\lambda$ .

A gas has an initial volume of 168 cm3 at a temperature of 255 K and a pressure of 1.6 atm. The pressure of the gas decreases to

denis23 [38]

I do not have a calculator, but let’s think...

Imagine a ballon with a certain amount of gas. When you decrease the volume by squeezing the balloon, you increase the pressure.

Which means volume is inversely proportional to the pressure:
PV=PV

Now to speed things up because class is about to start :/

PV/T=PV/T, I think

Tip: check your units and any questions let me know
