I'm taking physics and trying to figure out the 4 questions to this problem.

Answer:

It is often necessary to convert from one unit to another. For example, if you are reading a European cookbook, some quantities may be expressed in units of liters and you need to convert them to cups. Or perhaps you are reading walking directions from one location to another and you are interested in how many miles you will be walking. In this case, you may need to convert units of feet or meters to miles.

Chemistry is a subject studied in science.

Chemistry is the branch of Physical science, which undergoes the study of composition, structure, function, properties i.e., physical properties and chemical properties of the matter ( Solid, Liquid and Gas ) and the changes it undergoes.

Here, the matter that means that anything that have mass and occupies space.

Some of the branches of chemistry is as follows, Biochemistry, Analytical chemistry, Organic chemistry, Inorganic chemistry, Physical or computational chemistry.

Chemistry also studies the chemical interactions (bonding) between elements, atoms and molecules and also chemistry affects all aspects of life and mostly affects the natural process. Chemical things have been used much in our day today life.

Here, Anthropology is the study of Human beings, Baseball statistics can be studied under game or sports, Art is the study of culture.

Hence, Option A is the correct answer.

Answer:

Average speed is 14 m/s and average velocity is 10 m/s.

Explanation:

The time consumed to travel from A to B = Distance / Speed = 30 / 10 = 3 seconds

The time consumed to travel from B to C = Distance / Speed = 40 / 20 = 2 seconds

Now, we find the average speed by using the below formula.

Average speed = total distance / total time

Average speed = (30 +40) / (3 + 2)

Avergae speed = 70 / 5 = 14 m/s.

Now find the average velocity.

Average velocity = displacement / time

Displacement, distance between A to C = [(30)^2 + (40)^2]^1/2 = 50 m

Average velocity = 50 / (3+2) = 10 m/s

Answer:

B

Explanation:

This is a physics question, know that force is equals to mass divided by acceleration (acc.), so if the same force is applied, say 10 Newton and the mass of A is 2 and the mass of B is 4, then the acceleration of A is 0.2 and that of B is 0.4 by equating, and this applies to all cases.

Answer:

[tex]\Delta t = \dfrac{\Delta x}{v} \\\\[/tex]

Explanation:

Given the expression [tex]v\:=\dfrac{\Delta x}{\Delta t}[/tex], we are to find the value of Δt from the expression. To find Δt, we will make Δt the subject of the formula from the given expression as shown;

[tex]v\:=\dfrac{\Delta x}{\Delta t}\\\\cross\ multiply\\\\v*\Delta t = \Delta x\\\\Divide \ both\ sides \ of\ the \ resulting \ equation \ by \ v\\\\\dfrac{v*\Delta t}{v} = \dfrac{\Delta x}{v} \\\\\Delta t = \dfrac{\Delta x}{v} \\\\[/tex]

Explanation:

Given that a tennis ball moves 18 meters northward, then 22 meterssouthward, then 14 meters northward, and finally 28 meters

southward.

To calculate the displacement, let the

Northward = positive direction

Southward = negative direction

Displacement = 18 - 22 + 14 - 28

Displacement = 32 - 50

Displacement = - 18

Since the answer is negative,

Hey ! I think I can help with this question.

In the diagram you were given the speed which is 5.25m/s and you were also given distance which is 950metres.

So the formula which will be suitable in my own way will be speed=distance/time....Since you weren't given the time,then you can place the numbers in their respectively places which will be 5.25=950/time....Then you will cross multiply which will be 5.25t=950....Then 950÷5.25=180.952381 which is approximately 181. then don't forget to add your unit, time is measured in seconds so the answer is going to be 181seconds.This is what I know...I hope this helps you.....Thank you for the question

Hii! ^^

Explanation:

It is given that by using track and cart we can record the time and the distance travelled and also the speed of the cart can be recorded. With all this data we can solve questions on the laws of motion.  

Like using the first law of motion we can determine the force of gravity acting on the cart that has moved a certain distance and the velocity or the speed of card has already been registered and since time is known putting the values in formula would help us calculate the gravitational pull acting on cart.

so the answer is 2.7 years

Explanation:

Answer:

scalar d = 54000 m , v_average = 16,667 m / s

vector    d = -4000 m , moved 4000 to the west

                 v_average = 0                

Explanation:

his is a uniform motion exercise, but we must be careful with quantities that are scalars and vector quantities

The distance traveled is a scalar

       d = d₁ + d₂

       d = 25000 + 29000

       d = 54000 m

the speed is a scalar, in the exercise it is not specified if the speed of each trajectory or the average speed. Therefore we will calculate the two

       v₁ = d₁ / t₁

       v₁ = 25000/1500

       v₁ = 16,667 m / s

       v₂ = 29000/1740

        v₂ = 16,667 m / s

Since the two speeds are equal, the average speed is

       v = (v1 + v2) / 2

       v_average = 16,667 m / s

now let's calculate the displacement that is a vector, so it has direction in addition to modules

suppose the eastward direction is positive and the bold are vectors

      d = d₁ - d₂

       d = 25000 - 29000

        d = -4000 m

this means that it moved 4000 to the west

velocity is a vector, we assume positive eastward movement

        v₁ = 16,667 m / s

         v₂ = - 16,667 m / s

         v_average = (v1 -v2) / 2

         v_average = 0

Answer:

Explanation:

The first displacement when the mile reading changes from 257 to 145

= 257 - 145

= 112 km

Then he turns back . This time the displacement will be negative .

The mile reading changes from 145 to 175

displacement = - ( 175 -  145 )

= - 30 km

Final displacement = 112 - 30

= 82 km .

Answer:

The mass of the space probe on Ganymede is 126 kg, and its weight is 180.2808 N.

Explanation:

The force of gravity, g, on the earth is 9.8 m/[tex]s^{2}[/tex].

The gravitational force on Ganymede = 0.146 × g

                                                               = 0.146 × 9.8

                                                               = 1.4308 m/[tex]s^{2}[/tex]

The gravitational force on Ganymede is 1.4308 m/[tex]s^{2}[/tex].

Mass of space probe on Earth is 126 kg.

Weight of the space probe on Earth = m × g

                                                = 126 × 9.8

                                                = 1234.8 kgm/[tex]s^{2}[/tex]

Weight of the space probe on Earth is 1234.8 N.

Since mass is constant, the mass of the space probe on Ganymede is 126 kg.

Weight of the space probe on Ganymede = m × g

                                                     = 126 × 1.4308

                                                    = 180.2808 kgm/[tex]s^{2}[/tex]

Weight of the space probe on Ganymede is 180.2808 N.

Answer:

126 kg

Explanation:

Mass is a constant for a body, and does not change with location.

Answer:

The  time taken is  [tex]t = 32.5 \ s[/tex]

Explanation:

From the question we are told that

   The  speed  of  first car is  [tex]v_1 = 66.7 \ km/h = 18.3 \ m/s[/tex]

    The  speed  of  second car is [tex]v_2 = 52.7 \ km/h = 14.64 \ m/s[/tex]

   The  initial distance of separation is  [tex]d = 119 \ m[/tex]

The distance covered by first car is mathematically represented as

     [tex]d_t = d_i + d_f[/tex]

Here  [tex]d_i[/tex] is the initial distance which is  0 m/s

  and  [tex]d_f[/tex]  is the final distance covered which is  evaluated as [tex]d_f = v_1 * t[/tex]

So

     [tex]d_t = 0 \ m/s + (v_1 * t )[/tex]

     [tex]d_t = 0 \ m/s + (18.3 * t )[/tex]

The distance covered by second  car is mathematically represented as

     [tex]d_t = d_i + d_f[/tex]

Here  [tex]d_i[/tex] is the initial distance which is  119 m

  and  [tex]d_f[/tex]  is the final distance covered which is  evaluated as [tex]d_f = v_2* t[/tex]

       [tex]d_t = 119 + 14.64 * t[/tex]

Given that the two car are now in the same position we have that

    [tex]119 + 14.64 * t = 0 + (18.3 * t )[/tex]

   [tex]t = 32.5 \ s[/tex]
