Physics
1 answer:
ahrayia [7]3 years ago
6 0

Answer:

Elements in a period have wide range of chemical properties.

Explanation:

  • Period is the row of chemical elements's arrangement in the periodic table. It is numbered from 1 to 7.
  • In period as we move towards right the atomic number of element constantly increases along with the change in chemical properties.
  • As we move from left towards right in period, the valence electron number regularly increases in every element.
  • This valence electron differs the reactivity of the elements.

Help!<br> Is it possible for a child to have genetic material identical to one parent? Explain.
bagirrra123 [75]
No, you may have similar genetic material but not identical. You can have identical genetic material to your brother or sister if they are identical to you but not your parent because your genetic material consists of two people who have no relation to each other genetic material wise.

A centrifuge has an angular velocity of 3,000 rpm, what is the acceleration (in unit of the earth gravity) at a point with a rad
Anna71 [15]

Answer:

a_{r} = 1006.382g \,\frac{m}{s^{2}}

Explanation:

Let suppose that centrifuge is rotating at constant angular speed, which means that resultant acceleration is equal to radial acceleration at given radius, whose formula is:

a_{r} = \omega^{2}\cdot R

Where:

\omega - Angular speed, measured in radians per second.

R - Radius of rotation, measured in meters.

The angular speed is first determined:

\omega = \frac{\pi}{30}\cdot \dot n

Where \dot n is the angular speed, measured in revolutions per minute.

If \dot n = 3000\,rpm, the angular speed measured in radians per second is:

\omega = \frac{\pi}{30}\cdot (3000\,rpm)

\omega \approx 314.159\,\frac{rad}{s}

Now, if \omega = 314.159\,\frac{rad}{s} and R = 0.1\,m, the resultant acceleration is then:

a_{r} = \left(314.159\,\frac{rad}{s} \right)^{2}\cdot (0.1\,m)

a_{r} = 9869.588\,\frac{m}{s^{2}}

If gravitational acceleration is equal to 9.807 meters per square second, then the radial acceleration is equivalent to 1006.382 times the gravitational acceleration. That is:

a_{r} = 1006.382g \,\frac{m}{s^{2}}
