What are some differences you can spot in a periodic table?

Physics
1 answer:
Serggg [28]3 years ago
7 0

"The position of each element in the table gives important information about its structure, properties, and behavior in chemical reactions. Specifically, an element's position in the periodic table helps you figure out its electron configuration, how the electrons are organized around the nucleus."

A bicyclist steadily speeds up from rest to 6.00m/s in 7.30s.
Simora [160]

Answer:

21.899 m

Explanation:

The explanation here is a little differe because we are starting from rest. So, everyone does physics a little differently, but what I would start with is trying to find the accelaration. I've given the formula, now you are able to plug this into the displacement formula where you Velocity Initial = 0m/s (Since you are starting from rest) and V final = 6.00 m/s...

You just plug numbers into the formula after solving for accelaration and do some simple algebra! I hope this helps! I am attaching a new pdf for visuals! If you can't open it let me know! Also there is a star by accelaration because I didn't know if I spelled it right, sorry!

A child's first bicycle has 12-inch tires. These tires have a 6-inch radius. How fa r does the bicycle move forward each time th
Lilit [14]

Answer:

a. s = 0.96 m

b. s = 2.15 m

Explanation:

a.

The relationship between the linear displacement and the angular displacement is given as follows:

s = r\theta

where,

s = linear distance covered = ?

r = radius of wheel = (6 in)(0.0254 m/1 in) = 0.1524 m

θ = angular displacement = (1 rev)(2π rad/1 rev) = 2π rad

Therefore,

s = (0.1524\ m) 2\pi

<u>s = 0.96 m</u>

<u></u>

b.

Assuming, we have to find linear displacement here, as well:

s = r\theta

where,

s = linear distance covered = ?

r = radius of wheel = (13.5 in)(0.0254 m/1 in) = 0.3429 m

θ = angular displacement = (1 rev)(2π rad/1 rev) = 2π rad

Therefore,

s = (0.3429 \ m) 2\pi

<u>s = 2.15 m</u>

A man walks 6 km north, then turns and walks 6 km east what is the resultant and angle
gulaghasi [49]
That would depend on the man’s starting latitude. If 6.7 mi south of the north pole, for example, the resultant would be 6.7 mi due north of the starting point.

crimeas [40]
When light goes from one medium to another, it changes angle. This is why it will look bent.

a test tube has a diameter of 3cm . how many turns would a piece of thread of length 90.42 make round test tube​
nadya68 [22]

Answer:

4.8 turns would be made around the tube

Explanation:

You need the circumference of the tube since it's just a lifted circle

2×pi×3=18.85

90.42/18.85=4.79

And round that to 4.8
