Is the mass of an object measured with scale, yes or no​

Physics
1 answer:
mamaluj [8]3 years ago
7 0

Answer:

No.

Explanation:

The scale actually measures the force that the object does against it, and that force is called the weight.

Such that if we have an object with mass M and we are on Earth, where the gravitational acceleration is g, the weight is:

W = M*g

Now, there is a unit called "kilogram-force"

Such that on Earth, an object that has a mass of 10 kilograms, weighs 10 kilograms-force.

Then from the weight measure, we can instantly know the mass of the object, but the thing that is being measured is the weight, not the mass.

Several days after snowfall , the roofs of some homes on your street have almost no snow on them, while the roofs on other homes
Alina [70]

Explanation:

This due to thermal insulation of some of the roof.

An insulator is body is a poor conductor of heat and will require high thermal energy to cause temperature changes.

  • A house with a roof that is thermally insulated will have poor heat conduction.
  • Since little heat is conducted, there wont be enough thermal energy to melt the snow.
  • Thermal energy is directly related to heat.
  • A house that is not insulated will absorb a lot of heat.
  • This will cause the snow to melt very fast.

A spinning wheel on a fireworks display is initially rotating in a counterclockwise direction. The wheel has an angular accelera
nalin [4]

Answer:

5.74s

Explanation:

We can first solve for the initial angular velocity using the following formula

\omega^2 - \omega_0^2 = 2\alpha\theta

Where \omega = -22.4rad/s is the final angular velocity, \alpha = -22.4 rad/s^2is the angular acceleration and \theta = 0 is the angular displacement

22.4^2 - \omega_0^2 = 2*(-7.8)*0

\omega_0^2 = 22.4^2

\omega_0 = 22.4rad/s

So for the wheel to get from 22.4 to -22.4 with angular acceleration of -7.8 then the time it takes must be

t = \frac{\Delta \omega}{\alpha} = \frac{-22.4 - 22.4}{-7.8} = 5.74s

What happens to atomic numbers as you follow a period across the periodic table
geniusboy [140]

Answer:

As you move across a period, the atomic mass increases because the atomic number also increases

Explanation:

When the atomic number increases, this means that there are more protons and neutrons that add to the atomic mass of an atom.
