A cyclist rides in a circle with speed 8.1 m/s. What is his centripetal

Physics
1 answer:
Alina [70]2 years ago
5 0

Explanation:

We know that the tangent velocity is 8.1 m/s. We also know that the tangent velocity can be written in the following way:

Vt = ωr with ω being the angular velocity.

We now calculate ω:

ω = Vt/r = 8.1 m/s / 27m = 0.3 rad/s

Now that we have ω we can calculate the centripetal aceleration:

a = ω^2 * r = ( 0.3 )^2 * 27 = 2.43 m/s^2

What disadvantage of convex mirror​
nikklg [1K]

☁️ Answer ☁️

The main disadvantage of convex mirrors is that they show a distorted picture of what is behind you. Distances are seen not as they are in reality and things appear closer than they really are. They are showing cars approximately twice as far away as they actually are.

Hope it helps.

A(n)is produced around a wire when an electrical current is in the wire.
Nonamiya [84]

Answer: The correct answer is "magnetic field".

Explanation:

A magnetic field is produced around the current carrying wire.

If you bring compass needle around the current carrying wire then it shows the deflection which indicates that there is a magnetic  field around the current carrying wire.

Magnetic fields are the area around the surrounding of magnet in which magnetic force can be experienced.

Therefore, a magnetic field is produced around a wire when an electrical current is in the wire.
