Answer:

In order to properly take care of your skeletal system there are a multitude of activities or things you can do to improve the condition of your skeletal system. For starters you can exercise more often, depending on how much you already exercise because working out more is not always the best thing to do if you already have an intense exercise schedule. Then, you should take into consideration what you are eating and what vitamins, supplements, or medication you're taking. Once you have evaluated what your situation is, you should make a plan that best suits you based on your needs. Ingesting the proper nutrients and vitamins you need is essential to having a strong skeletal system, for example vitamin D and calcium are excellent supporters of the skeletal system.

Answer:

2 m/s

Explanation:

Given that,

Mass of a man, m₁ = 75 kg

Mass of object, m₂ = 5 kg

Velocity of the object, v₂ = 30 m/s

We need to find the recoil velocity of the man. Let it is v₁. In the whole process, the momentum of the system will remain conserved such that,

[tex]m_1v_1=m_2v_2\\\\v_1=\dfrac{m_2v_2}{m_1}\\\\v_1=\dfrac{5\times 30}{75}\\\\v_1=2\ m/s[/tex]

So, the recoil velocity of the man is 2 m/s

Answer:

The product of mass times velocity for both objects is the same.

Explanation:

They both have the same velocity. False

They both have the same mass. False: Because two objects of different masses can have the same momentum. The least massive of the two objects will have the greatest kinetic energy.

The product of mass times velocity for both objects is the same. True: Same momentum means that the large mass must have a small velocity; therefore, their product is equal to the small mass times a large velocity.

Mass and velocity is the same for both. False: Based on what was stated for the second option.

Answer:

Protection – Protect the wounded area with a support or something similar.

Rest – Do not continue to exercise while your wound is healing. It may take a few weeks or months to recover. You may need crutches or a sling.

Ice – Wrap a bag of ice or a bag of frozen peas in a towel and apply it to the wounded area for 15–20 minutes every two to three hours.

Compression – Apply elastic compression bandages to the wounded area during the day to reduce swelling.

Elevation – Make sure the injured body part is elevated above the height of your heart as much as possible to help reduce swelling.

Explanation:

Just did it.

Answer:

The five-step process for treating a muscle or joint injury such as an ankle sprain is called "P.R.I.C.E." which is short for Protection, Rest, Ice, Compression, and Elevation).

It can be used even by someone without first-aid training, and should be used immediately when an injury occurs – the earlier, the better – while further medical attention is being sought.

If the athlete experiences too much pain during the process, stop immediately.

"P" is for Protection

Protect the injured person and the area being treated but also protect yourself. If the injury occurs on the sports field, stop the game.

Protect the area being treated with a splint if possible.

If the athlete can move, carefully move them to a safer area using a stretcher or a crutch, but if there is any doubt, do not move the injured athlete.

"R" is for Rest

When a child is injured, the body responds in an effort to defend, localize, protect, and clean up the injured area, a response called inflammation. At the time of injury small blood vessels at the injury site rupture and cause tissue bleeding, which, in turn, can cause bruising and swelling.

Explanation:

There are five warning signs of inflammation:

Pain

Redness;

Tissue hotness;

Swelling, and

Loss of function.

Not every injury exhibits all these signs, but if your child is in pain then it is important to stop exercising immediately to avoid further damage.

"I" is for Ice

As soon as possible after injury, begin applying ice continuously for the first 15-20 minutes to decrease swelling and pain.

An ice bag can be applied directly to the skin (except on the outside of the knee) unless the child has a known cold allergy.

The safest form of icing is to use a plastic bag with ice cubes or crushed ice, or instant cold packs. Do not use “blue ice” or “gel packs”.

While icing will be uncomfortable at first, in 2 to 3 minutes, the skin will go numb and the ice bag will feel more comfortable.

If the child is very uncomfortable with ice bag, then a barrier like a wet towel can be placed between the ice and skin.

The ice bag can be secured in place using an elastic bandage, but the compression should not be too tight.

During the application of the ice, ask the child to wiggle their fingers/toes and monitor tissue around area that is being iced to ensure that they are not experiencing a lost of sensation.

Icing for 15-20 minutes with an ice bag is unlikely to cause nerve damage or frostbite; however, any loss of sensation and any changes in tissue coloration in areas other than the area that is being iced indicate that the application is no longer safe.

Because ice and plastic bags are so important, make sure that someone brings these to every practice and game. Better yet, to be on the safe side, bring your own!

Answer:

A change of one degree Celsius = a change of one Kelvin, but a Celsius temperature is never equal to a Kelvin temperature. A change of 1 degree Fahrenheit equals a change of 5/9 = 0.56 degrees Celsius. To convert a Fahrenheit temperature to Celsius, subtract 32 and multiply by 5/9.

Explanation:

The temperature difference in Celsius scale is greater than the temperature difference in Fahrenheit scale.

Change in temperature of 1°C = 9/5 × change in temperature of 1°F.

The physical concept of temperature indicates in numerical form how hot or cold something is. A thermometer is used to determine temperature.

Thermometers are calibrated using a variety of temperature scales, which historically defined distinct reference points and thermometric substances. The most popular scales are the Celsius scale, sometimes known as centigrade, with the unit symbol °C, the Fahrenheit scale (°F), and the Kelvin scale (K).

As change in temperature of 100°C = change in temperature of 180° F

change in temperature of 1°C = change in temperature of (180/100)°F

= 9/5 × change in temperature of 1°F.

Answer:

base ball data 55.1 N

football player 62.0 Kg

wagon data 3.64 m/s2

Explanation:

F=ma

a=f/m

m=f/a

force (N)

mass (KG)

acceleration (A)

The force exerted by Baseball is 55.01 N.

The mass of the Football player is 62.0 Kg.

The acceleration of the Wagon is 3.63 m/s².

Force is the influence that can change the state of the body of rest or motion. Force is a vector quantity and the SI unit of force is Newton. Force can change the direction and speed of the moving object.

The force can be determined by the product of the mass (m) and acceleration (a). The mathematical expression from the second law of motion for force can be written as:

F = ma

Given, the mass of the baseball is 0.142 Kg and the acceleration of the baseball is  388 m/s2.

The force exerted by the baseball, F = ma =  0.142 Kg × 388 m/s2

F =  55.096 N

F = 55.01 N

Given, the acceleration of the football player, a = 0.426 m/s2

The net force = 28.39 - 1.98 = 26.41 N

The mass of football player, m = F/a = 26.41/0.426 = 61.99 = 62.0 Kg

The force of the wagon, F = 128 N

The mass of the wagon = 77.6 Ibs = 77.6 × 0.454 Kg = 35.23 Kg

The acceleration of the wagon = 128/ 35.23 = 3.63 m/s²

Hey there!

Given;

Mass of the Earth (M) = 6.0*10^24kg.

Radius of Earth (R) = 6400km = 6400*1000= 6.4*10^6.

Gravitational constant (G) = 6.67*10^-11Nm^2/kg^2.

Height from surface of Earth (h) = 350km= 3.5*10^5m

Gravity (g) = ?

We have;

[tex]g = \frac{G.M}{ {(R + h)}^{2} } [/tex]

Where "G" is gravitational constant, "M" is mass of earth, "g" is acceleration due to gravity, "h" height from surface of Earth.

Keep all values.

[tex]g = \frac{6.67 \times {10}^{ - 11} \times 6.0 \times {10}^{24} }{ (6.4 \times {10}^{6} + 3.5 \times {10}^{5} )^2} [/tex]

[tex]or \: g = \frac{40.002\times {10}^{13} }{ (6.4\times {10}^{6} + 3.5*10^5)^2} [/tex]

g = 8.7m/s^2

Therefore, gravity from distance 350km above the Earth's surface is 8.7m/s^2.

The table of velocity of toy car is drawn below.

What is velocity ?

velocity is defined as rate of change of displacement of the object with respect to rate of change in time. In mathematics It is written as :

                                           [tex]\begin{aligned}v= \frac{\Delta d}{\Delta t}=\frac{d_{2}-d{1}}{t_{2}-t_1}\end{aligned}[/tex]

considering time interval from t=0 sec to t=2 sec the distance travelled by the toy car is d=0m to d=2m. therefore, the velocity will be :

                                      [tex]\begin{aligned}v&=\frac{d_{2}-d{1}}{t_{2}-t_1}\\&=\frac{2-0}{2-0}\\&=1 \text{\:m/s}\end{aligned}[/tex]

Answer:

S = 415.64m

Explanation:

Given the following data;

Time, t = 9.21secs

Since it's a free fall, acceleration due to gravity = 9.8m/s²

Initial velocity, u = 0

To find the height of the tower, we would use the second equation of motion;

[tex] S = ut + \frac {1}{2}at^{2}[/tex]

Where;

Substituting into the equation, we have;

[tex] S = 0*9.21 + \frac {1}{2}*(9.8)*9.21^{2}[/tex]

[tex] S = 0 + 4.9*84.8241[/tex]

[tex] S = 4.9*84.8241 [/tex]

Height, S = 415.64m

Therefore, the tower is 415.64m in height.
