A light-year is the distance light travels in one year (at speed = 2.998 × 108 m/s). (a) how many meters are there in 11.0 light

larisa [96]

<span>The answers are as follows:

(a) how many meters are there in 11.0 light-years?

11.0 light years ( 365 days / 1 year ) ( 24 h / 1 day ) ( 60 min / 1 h ) ( 60 s / 1 min ) ( 2.998x10^8 m/s ) = 1.04x10^17 m

(b) an astronomical unit (au) is the average distance from the sun to earth, 1.50 × 108 km. how many au are there in 11.0 light-years?

1.04x10^17 m ( 1 au / </span>1.50 × 10^8 km <span>) ( 1 km / 1000 m) = 693329.472 au

(c) what is the speed of light in au/h? au/h

</span>2.998 × 10^8 m/s ( 1 au / 1.50 × 10^8 km ) ( 1 km / 1000 m) ( 3600 s / 1 h ) = 7.1952 au/h

A motorist travels at 270 km in p hours at a certain average speed. an expression for the distance that this motorist travelled

wel

Average speed = total distance / time ⇒ total distance = average speed * time

Average speed = 270 km / p hours
distance = d
hours = x

d = 270/p * x

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 $\Delta t$ change 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.
