Weight = (mass) x (gravity)

Gravity on Earth is 9.8 m/s² .

The weight of 70 kg of mass on Earth is 

(70 kg) x (9.8 m/s²) = 686 newtons  (about 154.3 pounds)

You are creating waves in a rope by shaking your hand back and forth. Without changing the distance your hand moves, you begin t
scoundrel [369]

Answer:

<u>Amplitude - remains the same</u>

<u>Frequency - increases</u>

<u>Period - decreases</u>

<u>Velocity - remains the same.</u>

<u />

Explanation:

The amplitude of the wave remains the same since you are not changing the distance your hand moves and the amplitude of the wave depends on how much distance your hand covers while moving.

The frequency of your wave increases since now you are moving your hand more number of times in the same period i.e. your hand is moving faster in one second. So, the frequency of your wave increases.

The period is the time taken by the wave to travel a certain distance. Since your hand is now moving faster, the wave will travel faster and will take less time to cover the same distance hence, we can say that its period will decrease.

The velocity of a wave depends on the medium in which it is travelling. Your wave was previously travelling in air and the new wave is also travelling in the same medium so the velocity of the wave remains unchanged.

An ice skater has a moment of inertia of 2.5 kg.m2 when her arms are extended and a moment of inertia of 1.2 kg.m2 when her arms
Damm [24]

Answer:

\omega=4.7916\ rad.s^{-1}

Explanation:

Given:

  • moment of inertia of the skater with extended arms, I'=2.5\ kg.m^2
  • moment of inertia of the the skater with pulled-in arms, I=1.2\ kg.m^2
  • angular velocity of the skater with extended arms, \omega'=2.3\ rad.s^{-1}

<u>Using the law of conservation of angular momentum:</u>

I'.\omega'=I.\omega

2.5\times 2.3=1.2\times \omega

\omega=4.7916\ rad.s^{-1}

Compare the outermost electrons of an atom with the inner most electrons of an atom in terms of energy
iris [78.8K]
The innermost electron of an atom has the lowest level of energy while the outermost electron has the highest level of energy.
There are different energy levels in the atoms of elements, for an atom to go into an higher level it has to obtain more energy and to go to lower level it has to lose energy.<span />
