The following enumeration is the list of actions which are considered to be illegal when operating your boat:

1 Operating the boat in a harsh or inconsiderate manner

2 Operating the boat in the absence of safety equipment

3 Actual weight exceeds the carrying capacity of the boat

4 Not prohibiting the riders to sit on gunwales, transom, stern, sides, bow or decking over the bow sides when the boat is underway, except when sufficient guards or railings are provided

5 Operating the boat or giving permission to other people to operate the boat while drunk or under illegal substances

6 Operating the boat and the wash or wake endanger any property or person

7 Operating the boat in an area designated for swimming

8 Operating the boat beyond a slow, no wake speed in locations marked as no wake zones

We can see that in this case, the rule # 6 is being trespassed. Therefore under Minnesota Boating Laws, we have committed an Illegal Operating Practice.

Answer:

t=1.623 sec

Explanation:

The distance traveled before the echo is had is:

$distance=2d, d=280\ m\\\\=280\times 2\\\\=560 \ m$

Given the speed of sound as v=345m/s, we use the speed equation to solve for t:

$v=\frac{d}{t}\\\\345\ m/s=\frac{560m}{t}\\\\t=\frac{560}{360}\\\\=1.623 \ s$

Hence, it takes 1.623 seconds to hear the echo.

The amount of energy which is transported past a given area of the medium per unit of time is known as the ________ of the sound

Aliun [14]

The term that describes the amount of energy transported past a given area of the medium per unit time would be "intensity." In addition, the formula for computing intensity would be:

Intensity = Energy / (Time * Area)

It can be implied that the wave would be more intense when its energy transfer rate gets increased and vibration amplitudes also increases.

An automobile engine delivers 47.4 hp. how much time will it take for the engine to do 6.82 × 105 j of work? one horsepower is e

kogti [31]

1 horsepower is equal to 746 W, so the power of the engine is
$P=47.4 hp \cdot 746 \frac{W}{hp}=35360 W$
The power is also defined as the energy E per unit of time t:
$P= \frac{E}{t}$
Where the energy corresponds to the work done by the engine, which is $E=6.82 \cdot 10^5 J$ . Re-arranging the formula, we can calculate the time t needed to do this amount of work:
$t = \frac{E}{P}= \frac{6.82 \cdot 10^5 J}{35360 W}=19.3 s$
