Given the distance traveled and time elapsed, the average speed of the train is approximately 26.944m/s.

<h3>What is the average speed of the train?</h3>

Speed is simply referred to as distance traveled per unit time.

Mathematically, Speed = Distance ÷ time.

Given the data in the question;

  • Distance traveled = 221miles
  • Elapsed time = 3 hours and 40 minutes

First we convert miles to meters and Hours minutes to seconds.

221 miles = ( 221 × 1609.344 )m = 355665.024 meters

3 hours and 40 minutes = ( 3×60×60)s + ( 40×60)s

= 10800s + 2400s

= 13200s

Now, determine the average speed.

Speed = Distance ÷ time

Speed = 355665.024m / 13200s

Speed = 26.944m/s

Given the distance traveled and time elapsed, the average speed of the train is approximately 26.944m/s.

A baby elephant is stuck in a mud hole. To help pull it out, game keepers use a rope to apply force A, as part
aniked [119]

Answer:

The ratio is 1:1

Explanation:

Firstly we are told the in (a) we have a force which A given to be: FA

We are then told the are two other forces which a B and C which are equal.

These forces are given to be F and 19.5° away from A.

We are then told that the force on the elephant is now three times, of what it was when we only had force A.

Since we are told that B and C are eqaula.

If we say FA = 2N

Then in order for it to be three times, we would have to add 4N since it was the only force present at the time.

If we add two equal forces, then we can devide that 4 by 2.

We then find out that F =2N

and thus equal to FA.

Therefore the ratio of F/FA is

!:1

Masja [62]

Answer:

Explanation:

The source of all forms of energy found on the earth except nuclear energy is the sun . So energy used by us to do daily activities also comes from the sun .

The plants trap the solar energy in the form of light to make food material for us like sugar , carbohydrates etc . This energy is stored here in the chemical bonds formed  in them.  

We take this food in the form of carbohydrate, fat etc. We digest it to mix this food carbohydrate in blood . It is further broken down on being absorbed by the cell in our body . They break them to produce a compound like ATP ( adenocine triphosphate ) which is energy rich compound . It is converted into ADP and difference of energy is released . This energy is used by us in moving body parts.
