What is the magnitude of a vector if the x component is - 12 m and the y component is 21m?290m

17m

24m

580m

Answers

Answer:

v = 24 m

Explanation:

Given that,

The x component of the vector = 12 m

The y component of the vector = 21 m

We need to find the magnitude of a vector. It can be solved as follows :

v=√(12^2+21^2) \n\n=24.18\ m

or

v = 24 m

So, the magnitude of the vector is equal to 24 m.

What is your speed if you travel 7564 km in 23 hours? Convert this to miles per hour.

Answers

Answer:

[See Below]

Explanation:

Your average speed would be 204.35 mph.

i got appx. 204.3478 miles per hour because you convert 7564km/23hours to 4700miles/23hours, then divide 4700 and 23 by 23 to end up with 204.3478miles/1hour

Which particle is not part of an atom?a. proton
b. electron
c. neutron
d. magnetic domain

Answers

Answer:

Option D is the correct answer.

Explanation:

An atom consists of nucleus and electrons revolving around it.

Nucleus is filled with proton and neutron.

So atom consists of electron, proton and neutron.

Magnetic domain is not present in an atom.

Option A,Option B and Option C are present in an atom.

Option D is not present in an atom.

So Option D is the correct answer.
the particle that is not a part of the atom is the magnetic domain

How do you solve this question. I found the first part but don't know how to find distance

Answers

Why don't you try using the following kinematics formula

Vf^2 = Vi^2 + 2ad

Then solve for d, distance.

The distance it traveled during that time is

                 (average speed) x (length of time) .

The average speed is

                 (1/2) (starting speed) + (ending speed) .

They gave you the starting speed.
You calculated the ending speed.
So you can calculate the average speed.

They gave you the length of time.
So you can calculate the distance.
