Four charges are at the corners of a square centered at the origin as follows q at a a 2q at a a 3q at a a and 6q at a a A fifth
Wewaii [24]

Answer:

Vfx = 0.42 √x  and Vfy = - 0.729 √x

Explanation:

To solve this problem let's use the coulomb law applied to each load

        F = k q1 q2 / r²

Let's look for the distance from a corner to the center of the square

        r² = (a / 2) ² + (a / 2)²

        r = √ (a / 2)² 2

        r = a / 2 √2

Let's write the forces, in the attached there is a diagram of the charges

Charge q in the corner

         F1 = k q q / r²

         F1 = k q² / r²

         F1 = k q² 2 / a²

         F1 = 8.99 10⁹ (2.8 10⁻⁶)²   2 / 1.5²

         F1 = 62.65 10⁻³ N = 6.265 10⁻² N

charge 2q in another corner

        F2 = k 2q q / r²

        F2 = 2 k q² / r²

Notice that this force is twice the force F1, since the distances are equal

        F2 = 2 F1

3q charge

        F3 = k 3q q / r²

        F3 = 3 F1

6q charge

        F4 = k 6q q / r²

        F4 = 6 F1

Let's calculate the total force, for this it is useful to break down each force into its components and then add them, let's use trigonometry

        cos θ = Fx / F

        Fx = F cos θ

        sin θ = Fy / F

        Fy = F sin θ

Let's add each force

X axis

         Fx = F1x - F2x - F3x + F4x

         Fx = F1 cos 45 - 2F1 cos 45 - 3F1 cos 45 + 6 F1 cos 45

         Fx = 2 F1 cos 45

         Fx = 2 (6,265 10-2) cos 45

         Fx = 8.86 10-2 N

Axis y

         Fy = F1y + F2y -F3y -F4y

         Fy = F1 sin 45 + 2 F1 sin 45 - 3 F1 sin 45 - 6 F1 sin  45

         Fy = - 6Fi sin 45

         Fy = -6 (6,265 10⁻²) sin45

         Fy = - 26.54 10⁻² N

As we have the accelerations, we can find the speed on each axis

X axis

         Vf² = Vo² + 2aₓ x

         Vfx² = 2aₓ x

         Vfx² = 2 8.86 10⁻² x

         Vfx = 0.42 √x

Axis y

         Vfy² = vfy² + 2ay Y

         Vfy² = 2 ay Y

         Vfy² = -2 26.54 10-2 x

         Vfy = - 0.729 √x

A particular satellite with a mass of m is put into orbit around Ganymede (the largest moon of Jupiter) at a distance 300 km fro
sergij07 [2.7K]

Answer:

F = 402.18 N

Explanation:

Given that,

A particular satellite with a mass of m is put into orbit around Ganymede (the largest moon of Jupiter) at a distance 300 km from the surface. Let the mass of the satellite is 350 kg.

We need to find the gravitational force of attraction between the satellite and the moon.

The formula for the gravitational force is given by :

F=G\dfrac{Mm}{(R+h)^2}

M is mass of Ganymede

m is mass of satellite

R is Radius of Ganymede

h is distance = 300 km

Putting all the values,

F=6.67\times 10^{-11}\times \dfrac{1.48\times 10^{23}\times 350}{(2631\times 10^{3}+300\times 10^3)^2}\\F=402.18\ N

So, the required force of attraction between the satellite and the moon is 402.18 N.

Suppose a dolphin sends out a series of clicks that are reflected back from the bottom of the ocean 80 m below. How much time el
umka2103 [35]

Answer:

Time, t = 0.104 seconds

Explanation:

Frequency of the click of the Dolphin, f = 55.3 kHz

A dolphin sends out a series of clicks that are reflected back from the bottom of the ocean 80 m below, d = 80 m

The speed of sound in seawater is, v = 1530 m/s

Once the sound is send and reflects, the total distance covered by it is 2d such that,

t=\dfrac{2d}{v}\\\\t=\dfrac{2\times 80}{1530}\\\\t=0.104\ s

So, the time elapses before the dolphin hears the echoes of the clicks is 0.104 seconds.
