Which of the following is the correct relationship among the acceleration, velocity, and position?

Damm [24]

Answer:1

Explanation:

s=displacement

v=velocity of particle

a=acceleration of particle

acceleration can be written as rate of change of velocity

so $a=\frac{\mathrm{d} v}{\mathrm{d} t}$

multiply and divide by $ds$

$a=\frac{\mathrm{d} v}{\mathrm{d} t}\times \frac{ds}{ds}$

$a=\frac{\mathrm{d} v}{\mathrm{d} s}\times \frac{\mathrm{d} s}{\mathrm{d} t}$

$a=v\frac{\mathrm{d} v}{\mathrm{d} s}$

$ads=vdv$

option 1 is correct

A 10-kilogram bicycle is traveling at a speed of 2m/s. what is the bike's kinetice energy?

madam [21]

The kinetic energy of an object of mass m moving with speed v is given by:
$K= \frac{1}{2}mv^2$
For the bicycle in our problem, $m=10 kg$ and $v=2 m/s$ , so the kinetic energy is
$K= \frac{1}{2}(10 kg)(2 m/s)^2=20 J$

The difference in the composition of the terrestrial planets and the gas giants can be explained by the different condensation

miv72 [106K]

The inner planets are usually rocky because the gravitational pull is stronger closer to the star or in this case the sun. The dust and rocky particles that are left over after a super nova or in a nebula will tend to orbit closer to a proto-star when a solar system is in its early days. In our solar system these planets are Mercury, Venus, Earth and Mars. Gases are less dense and will be less affected by the pull of gravity because rocky particles have more mass. The outer planets are gas giants formed from clouds of gas that would be further out in the spinning disk around a proto-star.

A neutral atom contains 8 protons 9 neutrons, and 8 electrons the atom must be A. A oxygen isotope. B. A nitrogen isotope. C. A

Harrizon [31]

Answer:

A an Oxygen isotope

Explanation:

The number of protons is the Same as the atomic number

The atomic number is 9 is the atom has 9 protons

Thus, the atom is an oxygen isotope
