This question involves the concept of  Newton's law of gravitation.

The force of gravity between the two spaceships is "1355.78 N".

<h3>Newton's Law Of Gravitation</h3>

According to Newton's Law of Gravitation:

F=\frac{Gm_1m_2}{r^2}

where,

  • F = force of gravity between ships = ?
  • G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²
  • m₁ = mass of first ship = 500 kg
  • m₂ = mass of second ship = 498 kg
  • r = distance between ships = 35 m

Therefore,

F=\frac{(6.67\ x\ 10^{-11}\ N.m^2/kg^2)(500\ kg)(498\ kg)}{(35\ m)^2}\\\\

F = 1355.78 N = 1.356 KN

Two space ships traveling next to each other. The first one is 500 kg and the second one is 498 kg. They are 35 meters apart, the Force of gravity between the two spaceships is 1355.78 N.

It is given that the First spaceship's weight (m_{1}) is 500 kg,

The second spaceship's weight (\rm m_{2}) is 498 kg.

The distance between spaceships (r) is 35 meters.

It is required to find the Force of gravity between these spaceships.

<h3>What is Gravitational force?</h3>

It is defined as the force which attracts any two masses in the universe.

By Newton's law of Gravitation:

\rm F= \frac{Gm_1m_2}{r^2}  , Where

\rm F = The\  force \ of \ gravity \ between \ the  \ spaceships\\\rm G= Universal\  Gravitational \  Constant = 6.67 \times 10^{-11}  N.m^2/kg^2

Putting values in the above formula:

\rm F = \frac{(6.67\times 10^{-11}  N.m^2/kg^2)(500kg)(498kg)}{(35m)^2}

F = 1355.78 N = 1.356  KN

Thus, Two spaceships travel next to each other. The first one is 500 kg and the second one is 498 kg. They are 35 meters apart, the Force of gravity between the two spaceships is 1355.78 N.

A circuit contains four capacitors in parallel (10 F, 3 F, 7 F, and 1 F). What is the equivalent capacitance of this circuit?
goldfiish [28.3K]

The equivalent capacitance of this circuit is = 21F. That is option A.

<h3>Calculation of the equivalent capacitance</h3>

When capacitors are connected together in parallel the total or equivalent capacitance, CT in the circuit is equal to the sum of all the individual capacitors added together.

The four capacitors are 10 F, 3 F, 7 F, and 1 F.

Therefore the equivalent capacitance = 10 + 3 + 7 + 1=21F

An electron is moving through an (almost) empty universe at a speed of 628 km,/s toward the only other object in the universe —
sattari [20]

Answer:

  r = 2,026 10⁹ m  and   T = 2.027 10⁴ s

Explanation:

For this exercise let's use Newton's second law

        F = m a

where the force is electric

        F = k \frac{q_1q_2}{r^2}

Acceleration is centripetal

        a = v² / r

we substitute

        k \frac{q_1q_2}{r^2} = m \frac{v^2}{r}

        r = k \frac{q_1q_2}{m \  v^2}          (1)

let's look for the charge in the insulating sphere

          ρ = q₂ / V

          q₂ = ρ V

the volume of the sphere is

         v = 4/3 π r³

we substitute

        q₂ = ρ \frac{4}{3} π r³

        q₂ = 3 10⁻⁹ \frac{4}{3} π 4³

        q₂ = 8.04 10⁻⁷ C

let's calculate the radius with equation 1

        r = 9 10⁹  1.6 10⁻¹⁹  8.04 10⁻⁷ /(9.1  10⁻³¹ 628 10³)

        r = 2,026 10⁹ m

this is the radius of the electron orbit around the charged sphere.

Since the orbit is circulating, the speed (speed modulus) is constant, we can use the uniform motion ratio

        v = x / t

the distance traveled in a circle is

        x = 2π r

In this case, time is the period

        v = 2π r /T

        T = 2π r /v

let's calculate

        T = 2π 2,026 10⁹/628 103

        T = 2.027 10⁴ s

An empty elevator has a mass of 722 kg. It moves between floors at a maximum speed of 6.00 m/s. The elevator is stopped on the 2
FinnZ [79.3K]

Answer:

Explanation:

The lift is going down with acceleration

Initial speed u = 0

Final speed v = 6 m/s

distance s = 15.25 m

acceleration a = ?

v² = u² + 2 a s

6² = 0 + 2 x a x 15.25

a = 1.18 m /s²

Elevator is going down with acceleration  .

mg - T = ma where T is tension in the cable .

722 x 9.8 - T = 722 x 1.18

7075.6 - T = 851.96

T = 6223.64 N .
