An Object, Start from rest w Confront Aiceleration 8m/s2 along a

Physics
1 answer:
shutvik [7]3 years ago

Answer:

A)   v = 40 m / s, B)   v_average = 20 m / s

Explanation:

For this exercise we will use the kinematics relations

         

A) the final velocity for t = 5 s and since the body starts from rest its initial velocity is zero

         v = vo + a t

         v = 0 + 8 5

         v = 40 m / s

B) the average velocity can be found with the relation

         v_average = vf + vo / 2

         v-average = 0+ 40/2

          v_average = 20 m / s

Answer:

Explanation:

If a positive charge is moving in the direction of electric field vector, its velocity will increase, whereas positive charge moving opposite to the direction of the electric of electric field will decelerate.

The case with a negative charge is just reversed verse, it will decelerate when moving along the field direction and accelerate when moving opposite to it.

Ekaferini Stefandi of Greece won the women's pole vault at the 2016 Games in Rio with a vault height of 4.85 m. We are going to
Alecsey [184]

Answer:8.68 m/s

Explanation:

Given

If the height of vault is h=4.85 m

her center of mass is 1 m above ground

Net height h=3.85 m

conserving energy

Kinetic Energy=gain in Potential Energy

\frac{1}{2}mv^2=mgh

v=\sqrt{2gh}

v=\sqrt{2\times 9.8\times 3.85}

v=\sqrt{75.46}

v=8.68 m/s

How many carbon atoms placed end to end would equal the width of a human hair
xz_007 [3.2K]

The carbon atoms placed end to end would equal the width of a human hair are 1 million.

<h3>What is carbon?</h3>

The carbon is an element in the periodic table. It has atomic number 6 and the atomic mass 12 units.

Molecules anyway can shift in size from 0.1-0.5nm (nanometres) across so it would take a component of around 100,000 particles in width so that us might be able to see it with the unaided eye. Assuming that there's around 100,000 molecules in the width of one piece of hair, envision the number of there are in objects around you.

Learn more about carbon.
