Answer:

  • Define and measure speed.

Explanation:

According to a different source, these are the options that come with this question:

  • Estimate the speed of light.
  • Propose the heliocentric theory.
  • Discover radioactivity.
  • Define and measure speed.
  • Invent the reflecting telescope.

Galileo Galilei was the first person to attempt to measure speed, specifically the speed of light. He attempted to do this in the 1600s, with the help of an assistant. Galileo tried to measure how quickly light would travel from one hilltop to another one. However, light was so fast that it was impossible to measure it in this way.

What happens when you change the number of electrons in an atom
aalyn [17]
<h2>Answer: It becomes an Ion </h2>

When an atom has gained or lost electrons (negative charge), it becomes an ion.

In this sense:

<h2>Ions are atoms that have <u>gained or lost</u> electrons in their electronic cortex. </h2><h2> </h2>

If a neutral atom <u>loses electrons</u>, it remains with an excess of positive charge and transforms into a positive ion or <u>cation</u>, whereas if a neutral atom <u>gains electrons</u>, it acquires an excess of negative charge and transforms into a negative ion or <u>anion</u>.

It is then how ions form bonds with other atoms differently depending on the number of electrons they have.

A 3.00-kg ball swings rapidly in a complete vertical circle of radius 2.00 m by a light string that is fixed at one end. The bal
Setler [38]

Answer

given,

mass of the ball = 3 kg

swing in vertical circle with radius = 2 m

   work done by the gravity = ?          

   work done by the tension = ?            

Work done by the gravity = - m g Δh            

 Δ h = 2 + 2 = 4 m                                                                

Work done by the gravity =- 3 \times 9.8 \times 4

                                           = -117.6 J                  

work done by gravity is equal to -117.6 J            

Work done by tension will be equal to zero.        

Zero because tension is always perpendicular to velocity

work done by tension is equal to 0 J

What is the answer for number 10
Finger [1]

The vertical component is = vsinx m/s

If you know the angle, substitute the value of x.

If you know the velocity at which it is moving, substitute it for v

Hope it helps :)
