Explanation:

Average acceleration is the change in velocity over change in time.

a = Δv / Δt

a = (63 m/s − 25 m/s) / (17 s − 6 s)

a ≈ 3.45 m/s²

A nonmechanical water meter could utilize the Hall effect by applying a magnetic field across a metal pipe and measuring the Hal

Serga [27]

Answer:

The velocity is $v =2.455 \ m/s$

Explanation:

From the question we are told that

The diameter of the pipe is $d = 4.25 \ cm = 0.0425 \ m$

The magnetic field is $B = 0.575 \ T$

The hall voltage is $V_H = 60.0 mV = 60 *10^{-3} \ V$

Generally the average fluid velocity is mathematically represented as

$v = \frac{V}{ B * d }$

=> $v = \frac{60*10^{-3}}{ 0.575 * 0.0425 }$

=> $v =2.455 \ m/s$

Calculate the energy and power required for a student to bike their way to college from home. The student bikes from home for 0.

gregori [183]

Answer:

Check the explanation

Explanation:

To solve the problem, we need to analyze all forces acting on a bicycle individually. In question, student bikes on flat terrain so gravity force doesn't affect the road load. This is the case of uniform acceleration and deceleration so need to calculate average velocity to find Air resistance.

Kindly check the attached images below to see the step by step explanation to the question above.
