If he completes the 200 m dash in 23 s and runs at constant speed throughout the race, what is his centripetal acceleration as h

Blababa [14]

Incomplete question.The complete one is here

A runner taking part in the 200m dash must run around the end of a track that has a circular arc with a radius curvature of 30m. The runner starts the race at a constant speed. If she completes the 200m dash in 23s and runs at constant speed throughout the race, what is her centripetal acceleration as she runs the curved portion of the track?

Answer:

$a_c=2.523m/s^2$

Explanation:

Given data

$L_{length}=200m\\r_{radius}=30m\\t_{time}=23s$

Required

Centripetal acceleration

Solution

According to the motions equation the velocity given by:

$V_{velocity}=\frac{L_{length}}{t_{time}}\\V_{velocity}=\frac{200m}{23s}\\V_{velocity}=8.7m/s$

The centripetal acceleration is given by:

$a_{c}=\frac{V_{velocity}^2}{r_{radius}}\\ a_c=\frac{(8.7m/s)^2}{30m}\\ a_c=2.523m/s^2$

Abigail runs one complete lap (400m) around the track, while Gabi runs a 50 meter dash in a straight line. Which runner had a gr

Ipatiy [6.2K]

Answer:

$\boxed {\boxed {\sf Gabi \ had \ greater \ displacement}}$

Explanation:

Displacement is the change in the position of an object.

Abigail runs a complete lap around the track, which is 400 meters. Even though she ran 400 meters, she has no displacement. If she starts and ends at the same spot, there is no change in position.

Gabi runs a 50 meter dash in a straight line. Gabi has 50 meters of displacement. She runs in a straight line and is 50 meters away from where she began.

While Abigail ran the farther distance, Gabi had the greater displacement.

You are presented with several wires made of the same conducting material. The radius and drift speed are given for each wire in

Zigmanuir [339]

Answer:

d > a > b > c

Explanation:

Given that

a) radius = 3r and drift speed = 1v

b) radius = 4r and drift speed = 0.5v

c) radius = 1r and drift speed = 5v

d) radius = 2r and drift speed = 2.5v

Based on the above information, the ranking of the wires for reducing the electron current is

As we can see that the radius i.e to be less and the drift speed that is highest so it should be rank one

And, According to that, other options are ranked

Therefore, the ranking would be d > a > b > c

Identify and explain the three different ways that charge is built up on an object.

8090 [49]

Answer:

There are three ways to charge an object: friction, conduction and induction. Friction involves rubbing on material with another, resulting in electrons moving from one surface to another. ... Friction is useful for charging insulators, which are materials that aren't good conductors.
