Answer:

height = 1.5 x 10⁶ m = 1500 km

Explanation:

We can use the formula of gravitational force from the Newton's Gravitational Law:

[tex]F = \frac{Gm_{1}m_{2}}{r^2}[/tex]

where,

F = Gravitational Force = 6.6 x 10³ N

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²

m₁ = mass of earth = 6 x 10²⁴ kg

m₂ = mass of satellite = (1.02 tons)(1000 kg/1 ton) = 1.02 x 10³ kg

r = distance between center of earth and satellite = ?

Therefore, using these values in the equation, we get:

[tex]6.6\ x\ 10^3\ N = \frac{(6.67\ x\ 10^{-11} N.m^2/kg^2)(6\ x\ 10^{24} kg)(1.02\ x\ 10^3\ kg)}{r^2}\\\\r^2 = \frac{(6.67\ x\ 10^{-11} N.m^2/kg^2)(6\ x\ 10^{24} kg)(1.02\ x\ 10^3\ kg)}{6.6\ x\ 10^3\ N}\\\\[/tex]

[tex]r = \sqrt{61.84\ x\ 10^{12}\ m^2 }[/tex]

[tex]r = 7.86\ x\ 10^6 m[/tex]

The distance between center of earth and the satellite is equal to the sum of height of satellite and radius of earth:

[tex]r = height + radius\ of\ earth\\7.86\ x\ 10^6 m = height + 6.36\ x\ 10^6 m\\height = 7.86\ x\ 10^6 m - 6.36\ x\ 10^6 m[/tex]

height = 1.5 x 10⁶ m = 1500 km

Big  brain

Answer: The pressure exerted on a surface by an object increases as the surface area of contact decreases.

Explanation:

Pressure measures the amount of force exerted per a given area of an object. From this definition, the surface area of the object and force applied, affects the pressure applied.

As Benny presses his finger against a map, nothing happens to the map because the force applied is affected by the increased surface area of his finger. However as he presses a thumbtack into the map using the same force the tack will probably poke a hole in the map because the small( decreased) surface area of the sharp point of the thumbtack produces a much larger pressure on the map than the area of Benny finger. I hope this helps, thanks!

Answer:

a

Explanation:

In order to maintain speed, a moving object or person must move at a constant velocity. Accelerating will increase the speed while decelerating will reduce the speed.

Hence, for Bolt to be able to maintain the top speed for a few seconds, he needs to move at a constant velocity.

The correct option is a.

For calculate wavelength, lets applicate formula:

                                                      [tex]\boxed{\lambda = V/f}[/tex]

                                                   Δ   Being   Δ

                                            f = Frequency = 50 Hz

                                            v = Velocity = 340 m/s

                                             [tex]\lambda[/tex] = Wavelenght = ?

⇒ Let's replace according the formula:

[tex]\boxed{\lambda = 340\ m/s / 50 \ Hz }[/tex]

⇒ Resolving

[tex]\boxed{\lambda = 6,8\ m}[/tex]

Result:

The wavelength is 6,8 meters.

Good Luck!!

Incomplete question. However, I inferred you want an explanation for the assertion above.

Explanation:

Interestingly, humans have a diverse thought process, it is this diversity that makes part of us want to control how others behave forgetting that humanity is part of nature; which is also diverse.

For example, we know humans do not wings to fly, it is not part of our nature. Similarly, others do not display affection the same we do today and are so we need to respect their nature; their personality.

The child's radial/centripetal acceleration at the lowest point of the swing is

a = (3.00 m/s)² / (7.00 m) = 1.29 m/s²

By Newton's second law, the tension in the rope is

T = (3.5 kg) (1.29 m/s²) = 4.5 N

(Does the question really say the child's mass is 3.5 kg? That's little more than the average mass of a newborn, about 3.3 kg. Not exactly a good idea to put a newborn on a swinging rope...)

The statement that belongs to region X is  option (d)

(d) The main charge carriers are negative electrons

The reason for the selection is as follows;

The given region marked X belong to the NPN Transistor that has the following characteristics

The NPN transistor consist of a P-Type semiconductor sandwiched between two N-Type semiconductors

The charge carriers in a NPN transistor are negative electrons, while the charge carriers in a PNP transistor are holes

NPN transistor is the most commonly used type of BPT transistor due to the high mobility of electrons compared to holes

Electrons are passed from the emitter to the collector in an NPN transistor

Therefore, the statement that belongs only of the region marked X is that the main charge carriers are negative electrons

Heya!!

For calculate aceleration, lets applicate second law of Newton:

                                                   [tex]\boxed{F=ma}[/tex]

                                                 Δ   Being   Δ

                                              F = Force = 85,5 N

                                                  m = Mass = ?

                                             a = Aceleration = ?

First, lets calculate the mass using weight, for that lets use Newton law:

                                                    [tex]\boxed{m=w/g }[/tex]

                                                   Δ   Being   Δ

                                             w = Weight = 666 N

                                            g = Gravity = 9,82 m/s²

                                                   m = Mass = ?

⇒ Let's replace according the formula and clear "a":

[tex]\boxed{m = 666\ N / 9,81\ m/s^{2} }[/tex]

⇒ Resolving

[tex]\boxed{ m = 67,88\ kg }[/tex]

Like now we have the mass, lets calculate the aceleration:

⇒ Let's replace according the formula and clear "a":

[tex]\boxed{a=777 \ N / 67,88\ kg}[/tex]

⇒ Resolving

[tex]\boxed{ a = 11,445 \ m/s^{2}}[/tex]

Result:

The aceleration is 11,445 meters per second squared (m/s²)

A. The inner core heat produce stuff

it important for earth’s magnetic field that the inner core is hotter then the outer core because, the inner core provides the heat source for outer core convection. Hence, option c is correct.

Convection is a mode of heat transfer in fluids. The hotter fluid molecules rises from the surface and makes other molecules also hot.  The mantle fluid inside the earth core generates a convection current by the heat radiated from sun.

As a result of radioactive heating and chemical differentiation, the earth's outer core is currently experiencing turbulent convection. This creates a process where the convective kinetic energy is transformed into electrical and magnetic energy, much resembling a naturally occurring electrical generator.

In essence, electric currents are induced by the movement of electrically conducting iron in the presence of the earth's magnetic field. Hence, option c is correct.
