A bus is traveling with a uniform acceleration of 2.75 meters/second2. If the initial velocity of the bus is 16.5 meters/second,
Kaylis [27]
<span>The velocity will be 41.25 m/s2 after 9 seconds. To find velocity after a specific time period, multiply the acceleration (2.75) times the number of seconds (9) to receive 24.75 m/s, then add that to the initial velocity of 16.5 m/s. 24.75 + 16.5 = 41.25 m/s2.</span>

How is power defined? Question 8 options: the quantity of work accomplished the direction of the work the total distance an obje
kifflom [539]

Power is defined by the rate of work done by the object. Statement D represents the correct definition of Power.

<h3>What is Power?</h3>

Power can be defined as the transfer of energy from one place to another place. The rate at which this energy is transferred is called power.

In other words, the rate at which the work is done by an object is called its power. The mathematical representation of power is given as,

P = \dfrac {\Delta W}{\Delta t}

Here, P is the power, \Delta W is the change in energy or work done and  \Delta tchange in time.

The Power can be written in SI units as Watt or J/s.

Hence we can conclude that the power is the rate at which work is accomplished. Statement D is the correct representation of Power.

To know more about power, follow the link given below.

Our two intrepid relacar drivers are named Pam and Ned. We use these names to make it easy to remember: measurements made by Pam
kenny6666 [7]

This is a problem based on the logic and interpretation of the variables. From the measured data taken

what is collected by the two individuals is expressed as,

- NED reference system: (x, t)

- PAM reference system: (x ', t')

From the reference system we know that ν is the speed of PAM (the other reference system) as a measurement by NED.

Then ν' is the speed of NED (from the other system of the reference) as a measurement by PAM.

At TTT = 14 ∘C∘C, how long must an open organ pipe be to have a fundamental frequency of 262 HzHz ? The speed of sound in air is
Stolb23 [73]

Answer:

Length of pipe organ(L) = 0647 m (Approx)

Explanation:

Given:

Temperature (T) = 14°C

Fundamental frequency (F) = 262 Hz

Speed of sound (v) = 331 + 0.60(T) m/s

Find:

Length of pipe organ(L)

Computation:

Speed of sound (v) = 331 + 0.60(14) m/s

Speed of sound (v) = 339.4

Length of pipe organ(L) = Speed of sound (v) / 2(Fundamental frequency)

Length of pipe organ(L) = 339.4 / 2 (262)

Length of pipe organ(L) = 0647 m (Approx)
