D.Atoms can be divided into smaller parts.

Dalton's atomic theory was the first complete attempt to describe allmatter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that allmatter is made of atoms, which are indivisible.

A particle oscillates harmonically x = A cos(ωt + φ0), with amplitude 9 m, angular frequency π s −1, and initial phase π 3 radia

Gekata [30.6K]

Answer:

$t = \frac{5}{12} s$

Explanation:

As we know that the equation of particle position is given as

$x = A cos(\omega t + \phi_0)$

Now the speed of the particle is given as

$v = A\omega sin(\omega t + \phi_0)$

now we know that potential energy and kinetic energy is equal

so we have

$\frac{1}{2} mv^2 = \frac{1}{2}kx^2$

so we will have

$A^2\omega^2 sin^2(\omega t + \phi_0) = A^2\omega^2 cos^2(\omega t + \phi_0)$

$tan^2(\omega t + \phi_0) = 1$

$\omega t + \phi_0 = \frac{\pi}{4} or \frac{3\pi}{4}$

$\pi t = \frac{3\pi}{4} - \frac{\pi}{3}$

$\pi t = \frac{5\pi}{12}$

$t = \frac{5}{12} s$

anzhelika [568]

The Earth takes (365 and 1/4) days to orbit the sun. That's the length of our 'year'.

Since it's not really possible to make our calendar a quarter of a day longer every year, we make the calendar a <u><em>whole</em></u> day longer every 4 years.

So "Leap years" make up for the extra one-fourth day the Earth takes to orbit the sun.

What factor determines an object's momentum?

vlada-n [284]

Momentum = mass x velocity

So both mass and velocity affect an object's momentum.
