observe the figure given carefully volume of water in each vessel is shown arrange them in order of decreasing pressure at the base of each vessel explain the reason
Answers
Answer:
See the explanation below
Explanation:
The pressure is defined as the product of the density of the liquid by the gravitational acceleration by the height, and can be easily calculated by means of the following equation.
[tex]P=Ro*g*h[/tex]
where:
Ro = density of the fluid [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = elevation [m]
In this way we can understand that the greater pressure is achieved by means of the height of the liquid, that is, as long as the fluid has more height, greater pressure will be achieved at the bottom.
Therefore in order of decreasing will be
The largest pressure with the largest height of liquid, container B. The next is obtained with container D, the next with container A and the lowest pressure with container C.
The pressure decreases as we go from the container B - D - A - C

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]
similarly for interval t = (2sec - 4sec ) and t = (4sec - 6sec) is also calculate and written in table below.

Mercury is the plant from the sun
Answers
How Big Is Mercury?
Mercury is the smallest of the eight planets in our solar system. It is only a little bigger than Earth's moon. It would take more than 18 Mercurys to be as big as Earth. If you could weigh Mercury and the moon, Mercury would weigh much more. Mercury has a rocky surface, but deep inside is a heavier material, probably iron.
Where Is Mercury?
Mercury is the closest planet to the sun. On average, it is a little more than one-third the distance from the sun than Earth is. Or, put another way, Earth is almost three times farther from the sun than Mercury. Mercury orbits the sun once every 88 Earth days. So one year on Mercury is 88 Earth days. But a day on Mercury is longer than an Earth day. One Mercury day lasts for 59 Earth days.

Name each of the five steps in the PRICE treatment. (Site 1)
Answers
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!

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.
What is force?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

Answers
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.

If a man with a mass of 75 kg, standing still, throws an object with a mass of 5 kg at 30 m/s, what will be the recoil velocity of the man, assuming he is standing on a frictionless surface?
Answers
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]

Which statement correctly describes the charge of the nucleus and the charge of the electron cloud of an atom?
Answers
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of options. However, the charge of a nucleus was discovered by Ernest Rutherford. The nucleus is located in the centre of an atom and it contains protons and neutrons. The protons are positively charged while the neutrons have no charge, thus the charge of the nucleus is positive because the neutrality of the neutron does not affect the charge of the proton.
The charge of an electron was first measured by Robert Millikan. Electrons are negatively charged subatomic particles that balance out the positive charge of the protons.

be? What will be the direction of the velocity?
Anyone please help ???
Answers
Acceleration points in the same direction as the net force, so to the left.
The direction of velocity can't be determined from this information alone, though. If the object is at rest, it will being moving to the left. If the object is already moving to the left, it will continue doing so and speed up. If it starts off moving to the right, it will continue to move to the right but eventually slow to a stop before starting to move to the left. There are more cases to consider if you're talking about motion in more than one dimension.
Compare a change in temperature of 1°C to a change of 1°F.
Answers
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.
What is temperature?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.
