Vitellium (Vi) has the following composition:

Physics
1 answer:
irakobra [83]3 years ago
3 0

Answer:

C It will be closer to the mass of Vi–193.

Explanation:

The average atomic mass of vitellium will be closer to the mass of Vi–193.

From the geonormal abundance we can derive the average atomic mass or relative atomic mass of the compound.

 Average atomic mass = sum of all the product of the mass of isotope x abundance of isotope

Average atomic mass = (10.861% x 187.9122) + (12.428% x 190.9047) + (76.11% x 192.8938)

 Average atomic mass  = 20.41 + 23.73 + 146.81  = 190.95amu

What forces are being used when walking a dog and how ?
natta225 [31]
There are tons of forces that balance out on your body while you walk. Subsequent physics classes will tell you about each and how they are represented. Here are a few in order of how people usually learn them.

Gravity: The earth exerts a gravitational force on each particle in your body that has mass. Overall, this can be represented as a single force that pulls directly toward the center of the earth from the point called your center of mass.

Normal Force: The contact between your feet/shoes and the ground exerts a force normal (straight out from) the ground. If you are on flat ground, this force is directly opposite the force of gravity, and in most cases will be equal to it such that you have no vertical net force.

Friction: Friction between your shoes/feet and the ground, pointing parallel to the ground and in the direction of your walking motion creates the force necessary for you to move. The microscopic peaks and valleys of the ground and your feet/shoes create small normal forces that can sum into a direction of motion.

Air Buoyancy: Since you are in a fluid, the mass of the fluid you displace creates an upward force away from the center of the earth. Since the density of air is miniscule, this force is generally neglected except in the most precise of circumstances.

Drag and Air resistance: While you walk, as you move through a fluid, that fluid exerts friction on your body in the form of drag. It is usually small unless you’re moving very fast relative to the fluid.

Air pressure, blood pressure, body tensions: Your body has a balance of blood pressure, muscle tensions, which oppose outside air pressures which equalize out to form the shape your body is in.

Internal forces: Many forces act within you such as air pressure, other muscle tensions, and internal stresses which balance out. Usually in physics these are lumped under internal forces.

If you sit on a skateboard and push against a brick wall, what would happen? Why do you think this?
Troyanec [42]

Answer:

well when if you are sitting down and then push off of the brick wall you will be backwards so you can't see anything so you might hit someone or something so you would have to be careful

Explanation:

the reason why i think this is because i have a brother who skateboard and he wants to help me get better and when we are just playing we sit down on the skateboard and push off things and ran into a pole because i was backwards and wasn't paying attention so that's why i think that

A car of mass 1100kg moves at 24 m/s. What is the braking force needed to bring the car to a halt in 2.0 seconds? N
LenaWriter [7]

13200N

Explanation:

Given parameters:

Mass = 1100kg

Velocity = 24m/s

time = 2s

unknown:

Braking force = ?

Solution:

The braking force is the force needed to stop the car from moving.

   Force  =  ma = \frac{mv}{t}

  m is the mass of the car

  v is the velocity

  t is the time taken

  Force = \frac{1100 x 24}{2} = 13200N

What is the most useful meteorological measurement for forecasting freezing precipitation?
scoray [572]

The most useful meteorological measurement for forecasting freezing precipitation is b. radiosonde soundings

<h3>Radiosonde </h3>

At high altitudes, radiosondes are battery-powered telemetry sensor bundles that detect altitude, pressure, temperature, relative humidity, wind (both speed and direction), and cosmic ray measurements. They are commonly taken into the atmosphere by weather balloons.

Rawindsonde is an acronym for radar wind sonde, a type of radiosonde that tracks its position as it rises through the sky to provide wind speed and direction. Another type of radiosonde is one that falls to the ground after being released from an aircraft, as opposed to being carried by weather balloons. The term "dropsondes" is used to describe this group of radiosondes. The majority of operational atmospheric data assimilation methods depend heavily on radiosondes.

Hiro does not see a puddle of liquid on the lab table and accidentally touches the liquid. What should Hiro do next?
lys-0071 [83]

Answer: Option (B) is the correct answer.

Explanation:

It is advised that while conducting an experiment in a laboratory, always perform it under the supervision of your teacher.

When Hiro accidentally touches the liquid then he should immediately tell his teacher about it so that timely precaution can be taken to avoid any damage or side effect. Also, Hiro should rinse his hand in the sink because it will neutralize or decrease the effect of spilled liquid on his skin.

Thus, we can conclude that he should tell his teacher about the spill and rinse his hand in the sink.
