A typical carbon atom has six protons, six neutrons, and six electrons. Which of these has the least amount of mass?

Physics

Butoxors [25]3 years ago

One proton or one neutron have very close to the same mass.

Their mass is about the same as the mass of 1,840 electrons !
So six electrons have roughly the same mass as 0.0033 of one
proton or one neutron.

Yes, these masses are very tiny.  None of them was ever measured
until the 20th Century.  But all of them have now been measured,
very precisely and accurately.  This is very impressive, and should
give us a lot of admiration for scientists of the past hundred years.
It would be very interesting to look around online and find out
how they did it.

Answer:

the curve inclination is increased so that a weight component helps keep the car on track

Explanation:

In the sledging competition these devices go at quite high speeds over 100 km/h, so when reaching the curves the friction force is not enough to keep the car on the track. For this reason,  the curve inclination is increased so that a weight component helps keep the car on track.

In general we can solve Newton's second law for this case, with the condition of no friction, it is found that

   V² = r g tan θ

 Where V is the maximum velocity, r is the radius of the curve a, θ is the angle of the inclination

How can seismographs be used to predict hurricane intensity?
nikdorinn [45]

Answer: The earth is a noisy place. Seismometers, which measure ground movements to detect earthquakes, volcanic eruptions, and manmade explosives, are constantly recording smaller vibrations caused by ocean waves, rushing rivers, and industrial activity.

two bowling balls, a and b, each having a mass of 7.00 kilograms, are placed 3.00 meters apart. what is the magnitude of the gra
avanturin [10]

The magnitude of the gravitational force exerted by ball A on ball B is equal to 36.31 × 10⁻¹¹ N.

<h3>What is gravitational force?</h3>

Newton’s law of gravitation can be defined as every particle of matter in the universe attracting every other particle with mass with a certain force. The magnitude of gravitational force has a direct relationship with their masses.

Therefore, the gravitational force between two bodies can be written as:

\displaystyle F =G\frac{M_1M_2}{r^2}

Where G denotes the universal gravitational constant.

Given, the mass of the Ball A = Ball B = 7 Kg

The separation between the two balls, r = 3 m

The magnitude of the gravitational force applied by ball A on ball B can be determined as:

\displaystyle F =6.67 \times 10^{-11} \times \frac{7\times 7}{(3)^2}

F = 36.31 × 10⁻¹¹ N

Therefore, the gravitational force is equal to 36.31 × 10⁻¹¹ N.

olga nikolaevna [1]

Answer:

B. Marginal cost equals long-run average total cost.

Explanation:

The zero profit condition implies that entry continues until all firms are producing at minimum long run average total cost. Since the marginal cost curve cuts the long run average total cost curve at its minimum point, marginal cost and long run average total cost must be equal in long run equilibrium.
