What do the arrows at point 3 indicate?

Cool air is above water.
Warm air is above land.
Warm air is cooling quickly.
Cool air is warming quickly.

So velocity means speed (how fast something is moving) with a direction for math and science.

Example: Its the same thing as using the word like: Wow that car has a really high Velocity.

Hope this helps :D

Answer:

[tex]F_{grav}[/tex] is a field force, as gravity does not physically apply force and does not require proximity.

Answer:

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 2 × 5

We have the final answer as

Answer:

Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects. Forest fires are caused due to the friction between tree branches. However, friction can also cause problems in a car. Friction between moving engine parts increases their temperature and causes the parts to wear down. Friction can be both harmful and helpful, so it may be necessary to decrease or increase friction.

Answer:

Friction had many disadvantages and these are the har,s of friction too.

Explanation:

Disadvantages of friction are mainly forest fires, decreasing life expectancy of vehicles, damages many machines, generates heat, wear and tear, wastage of force/energy, etc. When two things in a forest rub against each other through an amount of force, friction will be present and it will cause a spark. This spark will be continued into a fire because of other materials like wood in the forest causing a forest fire. Secondly, vehicles work through moving many internal machines in them; this again includes friction and friction can damage the machines so to prevent it ppl grease the machines. decreasing life of vehicles is just a larger view of damaging the machines as this disadvantage of friction can be used anywhere. Wastage of force/ energy because when we roll a ball on a surface we have to put force on the ball to make it move forward but because friction moves in the opposite direction energy/force will be wasted there. Generating heat and wear & tear are some factors of friction which is also a harm.

Answer: When you touch wet canvas, surface tension will draw water to your finger. However, the drop left behind where you touched, like any irregular point on an overhead surface, will draw condensation from inside the tent if it is humid.

Answer:

m = 664.821 kg

General Formulas and Concepts:

Physics

p = mv

Explanation:

Step 1: Define variables

m = unknown

p = 3723 kg * m/s

v = 5.6 m/s

Step 2: Find mass

3723 kg * m/s = m(5.6 m/s)

m = 664.821 kg

Answer:

(I UNDERLINED AND MADE ITALIC THE MOST IMPORTANT INFORMATION) A vocation is an occupation to which a person is especially drawn or for which they are suited, trained, or qualified. Though now often used in non-Latin vocātiō 'a call, summons')religious contexts, the meanings of the term originated in Christianity.  (from

Explanation:

A call, summons, or impulsion to perform a certain function or enter a certain career, esp. a religious one. Vocation is defined as a call to do something, especially regarding religious work. The woman's desire to become a nun is an example of vocation. a strong impulse or inclination to follow a particular activity or career. a divine call to God's service or to the Christian life. a function or station in life to which one is called by God: the religious vocation; the vocation of marriage. There are many different types of vocations in today's society. The three significant vocations are, single life, married life, and religious life. Single life is one of the three types of vocation. Definition of Vocation and Career: Vocation is what you strive to do in your life. It is the career you want to be in. Career, on the other hand, is a series of jobs, even change of professions, in a lifetime of an individual. Vocation is literally your "calling", what you are good for or destined for. It usually is a property/talent/predisposition of your person. A mission, in contrast, is a particular task given to you. Even if you are on "a mission from God", there may be retirement from it eventually.

Answer:

i have to say whether its correct or wrong yep

Answer:

C) The direction the car is traveling

Explanation:

Velocity is a vector that contains both direction and magnitude (Speed)

We already know the magnitude... all you need is the direction.

Answer:

'distance' is a 'dependent' variable, and 'stopping' distance is 'an independent' variable.

Explanation:

As we know the independent variable is basically the variable the independent variable is the variable the researcher or a lab person tends to change or control, and its tendency to have a direct effect on the dependent variable.

In this example, two cars are on a track and accelerate to 60 mph. At a certain point, both cars slam on the brakes. The distance it takes for each car to stop is then measured.

It means the 'covering' distance depends upon where the cars tend to stop. It can be a long-distance depending upon how fat the cars go before both cars slam on the brakes.

Therefore, 'distance' is a 'dependent' variable, and 'stopping' distance is 'an independent' variable.

Answer:

Explanation:

All the energy in oil, gas, and coal originally came from the sun, captured through photosynthesis.for example when  we burn wood to release energy that trees capture from the sun, we burn fossil fuels to release the energy that ancient plants captured from the sun. We can think of this energy as having been deposited in a natural solar power bank over millions of years.

So, in one sense, gasoline-burning cars, coal-burning power plants, and homes heated by natural gas are all solar powered!

Answer:

A pair of scissors used to cut a piece of cloth has blades longer than the handles so that the blades move longer on the cloth than the movement at the handles.

While shears used for cutting metals have short blades and long handles because as it enables us to overcome large resistive force by a small effort.

Answer:

Force = 8.0 k g m / s

Explanation:

Force = mass x acceleration

Mass = 4.0 k g Acceleration = 2.0 m / s 2

Hence,force = ( 4.0 x 2.0 ) k g m / s 2 = 8.0 k g m / s 2

Explanation:

PEACE OUT!

Answer:

the answer choice is B

Explanation:

as we move from left to right , the atomic size decreases due to higher number of protons in the nucleus, which are able to attract the electrons more strongly. and so the electronegativity and  electron affinity increases for the same reason. the nuclear charge increase due to more protons , and without an increase in inner electrons , there is less shielding effect. so effective nuclear charge increases.

Answer: B. electronegativity

Explanation: Electronegativity generally increases as you move of the periodic table and as you move to the right. All the other answers listed decrease as you move up a column of the periodic table.

Answer:

When we say that an object moving in the +x axis experiences an acceleration of 2.0 m/sec2, it really means the object is increasing its velocity by 2.0 m/s in every second.

Explanation:

As we know that Acceleration is the rate of change of velocity with respect to time, in terms of both speed and direction.

i.e.

a = Δv/Δt

so when we say that an object moving in the +x axis experiences an acceleration of 2.0 m/sec2, it really means the object is increasing its velocity by 2.0 m/s in every second.

Answer:

bicycle A has a greater K.E.

Explanation:

K.E = 1/2mv²

bicycle A = 1/2 × 40 × 4² = 320J

bicycle B = 1/2 × 20 × 2² = 100J

bicycle A has a greater K.E. because it has bigger mass and moves with faster velocity

Answer:

The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension, T. When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.
