is the best estimate of the density of the air on the planet.
Given:
The mass of the conical flask with stopper is 457.23 grams and the volume is .
Mass of conical flask and a stopper after removing the air is 456.43 g
To find:
The density of the air on the planet.
Solution;
Mass of the conical flask and stopper with air on the planet= 457.23 g
Mass of conical flask with a stopper and without air on the planet = 456.43 g
Mass of the air in the conical flask on the planet =m
The volume of the conical flask =
The volume of the air in the conical flask =
The density of the air on the planet = d
is the best estimate of the density of the air on the planet.

F=ma, so 100=m×10. Solve for m by dividing by 10. The mass is 10 kg.
The characteristics of electromagnetic radiation include amplitude (brightness), wavelength, frequency, and period. We have shown that the frequency of a light wave is proportional to its energy by the equation E = h v or E=hnu
so
Radiation with a wavelength of 8.1 X 10^-8 m has the highest energy
<h3>Why is it called electromagnetic?</h3>
- When a charged particle, like an electron, changes its velocity—that is, when it is accelerated or decelerated—electromagnetic radiation is created. The charged particle is responsible for losing the energy of the electromagnetic radiation that is thus created.
- Since the electric and magnetic fields are oscillating, the waves of energy are known as electromagnetic (EM). They are categorized by scientists based on their frequency or wavelength, from high frequency to low frequency (short to long wavelength).

Answer:
As the object falls it loses potential energy and gains kinetic energy
Explanation:
When the object reaches the ground its final KE will be equal to its original PE
You said T = 2 · π · √(L / g)
(I think that's the formula for the full-swing period of a simple pendulum.)
Divide each side by 2π : T/2π = √(L / g)
Square each side: (T/2π)² = L / g
Multiply each side by ' g ' : L = g · (T/2π)²
