If the earth was hollow and you jumped into the middle, what would happen?

Answer:

The spring balance (also known as spring scale) is simply a spring fixed at one end with a hook to attach an object at the other. It works by Hooke's Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position.

HOW IT WORKS:

It consists of a spring fixed at one end with a hook to attach an object at the other. It works by Hooke's Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position. Therefore, the scale markings on the spring balance are equally spaced.

Answer:

Magnitude = 18 m

Direction = southward

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,

The magnitude will be 18 m and direction of the displacement is southward

Answer:

18.0 cm/s2

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:

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.

On EDG

Explanation:

It is given that, the force of gravity pulls down on your school with a total force of 400,000 N.

The force of gravity is given by the formula as follows :

F = mg

m is mass and g is the acceleration due to gravity

Mass of an object remains same always. But if the mass of your school becomes twice of the initial mass, the force of gravity pulling down on your school would be exactly twice.

Answer:

The distance is  [tex]z = \frac{1 + \sqrt{ \frac{k * q_2 }{ k * q_1}}}{s}[/tex]

Explanation:

From the question we are told that

   The positive charges is  [tex]q_1 \ and \ q_2[/tex]

   The distance of separation is  [tex]s[/tex]

Generally at the point where the electric field is zero  would be a point where

The  electric field due to [tex]q_1[/tex] =  The  electric field due to [tex]q_2[/tex]

Generally the electric field due to [tex]q_1[/tex] is mathematically represented as

     [tex]E_1 = \frac{k * q_1}{ z^2 }[/tex]

Since we are taking our reference from [tex]q_1[/tex] then the electric field due to [tex]q_2[/tex] is mathematically represented as

     [tex]E_2 = \frac{k * q_2}{ (s- z)^2 }[/tex]

So

     [tex]\frac{k * q_1}{ z^2 } = \frac{k * q_2}{ (s- z)^2 }[/tex]

      [tex]k * q_1 * (s- z)^2= k * q_2 * z^2[/tex]

      [tex][ \frac{s -z }{z} ]^2 = \frac{k * q_2 }{ k * q_1}[/tex]

      [tex]\frac{s -z }{z} = \sqrt{ \frac{k * q_2 }{ k * q_1}}[/tex]

     [tex]\frac{s}{z} - 1 = \sqrt{ \frac{k * q_2 }{ k * q_1}}[/tex]

     [tex]z = \frac{1 + \sqrt{ \frac{k * q_2 }{ k * q_1}}}{s}[/tex]

Earth or ground

Explanation:

Earth is the reference point in an electrical circuit from which voltages are measured, it connects the house's electrical system physically to the ground.  It functions in a house to ensures that exposed electrical parts do not have a dangerous voltage relative to the Earth, which could cause an electric shock if a grounded person touched them, and also to make sure that the failures of internal insulation triggers protective mechanisms such as fuses or circuit breakers in the circuit to remove power from the device.

Hey there!

Step one: Find how many miles you can travel per day.

45(24)=1008. You could travel 1008 miles a day.

Step two: Convert 1008 miles to meters.

1008 miles roughly equals 1622219 meters.

Step three: Convert meters to Altuves.

1622/1.65=983.03 Altuves.

Explanation:

as we know that  

K.E =1/2 mv²

where m is mass and v is velocity

given mass= 1120 kg

given velocity =40 m/s

so K.E=1/2 (1120)(40)²

K.E=1792000/2

K.E=896000

K.E=8.9*10^5

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]

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.

Answer:

40,000 meters

Explanation:

We want to find how far the car travels, or the distance. Therefore, we can use the following formula:

[tex]d= s*t[/tex]

where [tex]s[/tex] is the speed and [tex]t[/tex] is the time

The speed of the car is 40 meters per second and the time is 1000 seconds. Therefore,

[tex]s= 40 m/s*\\t=1000s[/tex]

Substitute the values into the formula.

[tex]d= 40 m/s * 1000s[/tex]

Multiply. When you multiply, the 2 "s" variables will cancel out.

[tex]d= (40 m*1000)[/tex]

[tex]d= 40,000 m[/tex]

The distance traveled by the car is 40,000 meters.
