Will the pressure in glass of fruit juice be bigger or smaller than the pressure in water?

Answer:

a) Vi = 137.2 m/s

b) h = 960.4 m

Explanation:

a)

In order to find the initial speed we will use first equation of motion:

Vf = Vi + gt

where,

Vf = Final velocity = 0 m/s (since ball stops at highest point)

Vi = Initial Velocity = ?

g = - 9.8 m/s² (negative sign for upward moyion)

t = time interval = 14 s

Therefore,

0 m/s = Vi + (-9.8 m/s²)(14 s)

Vi = 137.2 m/s

b)

Now, we use second equation of motion to find height (h):

h = Vi t + (1/2)gt²

h = (137.2 m/s)(14 s) + (1/2)(-9.8 m/s²)(14 s)²

h = 1920.8 m - 960.4 m

h = 960.4 m

Explanation:Flexibility and stretching: preventing sports injuries

  Many may know about all the different types of sports around the world. Lots can leave serious injuries. All across the world more than 1.2 million people have been injured because of sports or maybe more than that. Most of the injuries have been kids. To prevent these injuries from happening. One thing is stretching if you  don’t stretch your bones more than likely you are not into your flexibility and reflexus that for they are very weak. If there is not enough flexibility within your movement you are more than likely not able to stretch. It can help the growth within your bone as well. If you have growth in your bones then you will get less injuries. If you break a bone such as your leg or sprain there is a chance that you will have problems with that specific leg later on in life. To prevent these types of events from happening I say stretch before a sporting game. Stretching can help with the impact of your  flexibility. For example, Olympic gymnasts are able to do lots of tricks because their bones have flexibility in their bones. That's not saying that they will not hurt themselves, it's just such a low risk because their bone grew strength and flexibility. Some people's bones can be very sensitive then others so it might be kind of hard for them to be flexible. Another way to help people with their bone flexibility is drinking milk. Milk helps grow your bones. This can help prevent sport injuries in many ways. Lots of people get hurt in football to be more specific because it's such a durable sport as in tough. If they drink a lot of protein and milk before a game maybe even Carbohydrates their bones will be ready for the game. Flexibility and stretching can go lots of ways when it has to do with your body.  JUST STAY FIT

Answer:

Carbon-14 decays relatively quickly

Explanation:

i took the test

Answer:

5.6 m/s

Explanation:

The acceleration of any possible is the ratio of the velocity of the particle with respect to the time the particle takes in moving. It is mathematically represented as

a = v/t, with m/s² as it's unit, where

v = velocity in m/s

t = time taken in seconds

a = acceleration in m/s²

From the explanation above, we were given in the question that, the speed is 112 m/s and the time if took is 20 seconds, thus, the acceleration is

a = 112/20

a = 5.6 m/s²

Therefore, the magnitude of the acceleration is 5.6 m/s²

We have that the average acceleration is

[tex]a=5m/s^2[/tex]

From the Question we are told that

Decreases his velocity from 20 m/s to 10 m/s in 2.0 s.\

Generally the equation for the average acceleration  is mathematically given as

[tex]a=\frac{u-v}{t}\\\\a=\frac{20-10}{2}[/tex]

[tex]a=5m/s^2[/tex]

Explanation:

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.

Elements located in the vertical column of the periodic table are of the same group and have similar chemical properties, therefore the correct answer is option A and option C.

The total number of protons present in an atom is known as the atomic number of that atom.

While the atomic mass of an atom is the sum of the total number of protons and the number of neutrons present inside any atom.

The element belonging to the same group have approximately similar chemical behavior while on the other hand element belonging to the same period would have the same outermost shell.

The correct response is option A and option C because elements included in the vertical column of the periodic table belong to the same group and have comparable chemical characteristics.

Explanation:

Given:

v₀ = 0 m/s

v = 3.0 m/s

t = 3 s

Find: a

a = (v − v₀) / t

a = (3.0 m/s − 0 m/s) / 3 s

a = 1 m/s²

Answer:

There are so many things that make human travel difficult.

Here are some ideas ;

1) Air and Water -Taking water and oxygen from the Earth is very expensive and very difficult. (Note that if there is lots of water, oxygen can be made from the water. Also, if there is carbon dioxide, oxygen can be made.)

2) Food - people will need to grow their own food on another planet - transportation to and from Earth is, again, too expensive. Plants need carbon dioxide and sunlight (real sunlight is best; artificial lighting will work, too.)

3) Energy - Human settlements will need to create their own energy. Energy can be created using the sun.

Note that these powers have their own advantages and disadvantages

4) Radiation - Radiation is harmful for people, plants and animals. On Earth, we are protected by a magnetic field and an atmosphere. Some planets and moons have neither; some have only one or the other. Very few have both. Some planets have very strong magnetic fields that create even more radiation. Crazy right .

5) Gravity - planets or moons with a lesser gravitational pull than the Earth will result in astronauts having smaller bone and muscle mass, which is a serious problem if they are to come back to Earth. The closer a planet's gravity is to Earth, the less of a problem this is.

6) Atmosphere - Some planets have no atmosphere while some have atmospheres that will crush people(Woah ) .It's easier to deal with low-pressure rather than high-pressure, but both are dangerous if there is an air leak.

7) Distance - the further a planet is from Earth, the harder it is to.

8) Temperature - The hotter or colder a planet is, the more energy it will take to change the temperature(and im not really sure how ).
