The acceleration of the rider initially going at a speed of 15m/s but comes to a stop at 50m is 2.25m/s².

The acceleration of a moving body can be calculated by using the following formula:

v² = u² + 2as

Where;

15² = 0² + 2×a×50

225 = 0 + 100a

a = 225/100

Building a pipe organ with open-tube pipes spanning the range from 25 hz to 19 khz will require the length of the shortest pipe to be 0.018m

This is defined as the measurement or extent of a substance from end to end. The formula is shown below:

L = v/f where v is speed , f is frequency

f1 = 25hz , f2 = 19khz

The length for both sides is seen below:

l1 = 343/25 = 13.72m

l2 = 343/19000 = 0.018m.

The length of the shortest pipe is therefore 0.018m.

The frequency of a repeated event is the number of occurrences per unit of time. The length of the shortest pipe is 0.018 m.

The frequency of a repeated event is the number of occurrences per unit of time. It is also known as temporal frequency to distinguish it from spatial frequency, and ordinary frequency to distinguish it from angular frequency.

The formula of the length is given by the formula,

[tex]L=\dfrac vf[/tex]

where v is the velocity of the substance and f is the frequency.

Given that the speed of the sound in air is 343 m/sec, while the frequency is tanging from 25Hz to 19 kHz.

Therefore, the length of the pipe will be,

[tex]L=\dfrac vf\\\\L_1=\dfrac{343}{25} = 13.72\rm\ m[/tex]

Answer:

Weight of the body in air = 20gf ( Wa)

Weight of the body in water = 18gf ( Ws)

Weight of the body in liquid =18.2gf ( Wl)

Now,

The loss of weight in the water = 20 - 18 or, 2 gf

So the relative density of the body is = Wa / ( wa - ws )

= 20 / 2

= 10

2) The weight loss in liquid = 20 - 18.2 or, 1.8 gf

So the relative density of the liquid is =( Wa - Wl ) / ( Wa - Ws )

= 1.8 / 2

The differences between the Florida's weasel and in Wyoming's is that I can see that in Wyoming it has a lot of snow so Wyoming's weasel fur is more thicker than Florida's weasel.

Explanation:

Overmore, in Florida's weasel the weasel's fur is much more less then Wyoming's weasel's fur. Subsequently, their fur color is very different. In Wyoming's weasel fur, it's white fur help them blend in the snow. In Florida's weasel fur, it's brown and help blend in the grass(soil).

Weasels are small animals with long tail. Their diet will change in each seasons and will causes consecutive changes in body weight also.

The changes occurs in a living body or in a material with respect to different seasons is called seasonal changes.Weasels have coats that change from light brown to white in the winter. They are also known as ermines or short-tailed weasels.

In both the spring and the fall, the hue of their bodies changes, starting at their belly and moving outward. Long-tailed weasels and other species may also turn at least partially white.

The hue shift is caused by daylight duration rather than temperature. Weasels may therefore appear dazzling white in the winter against a brown environment before snow begins to fall. This makes them easy prey for larger predators like foxes, martens, and badgers during milder winters.

These little creatures eat a lot. Winter weasels forage often and consume roughly 40% of their body weight each day. Winter weasels have coats that change from light brown to white in the winter.

These pests, which can weigh as little as two ounces, are vicious and may attack prey that is larger than themselves. Weasels have excellent senses and are highly nimble. Because of this, they are difficult to catch and remove, both for humans and for predators.

Weasels are a sign of a healthy population of rodents or other prey on a property in the winter. The pests frequently reserve a portion of their meals for later.

The Reagan travel over an angle of 4π/3radians is 10.47 or 10 feet if the Reagan rides on a playground roundabout with a radius of 2. 5 feet.

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

We have Reagan rides on a playground roundabout with a radius of 2.5 feet.

We know the relation between arc length and radius of the circle:
