Vlad1618 [11]

Answer:

Volume of Sand = 0.4 m³

Radius of Sand Sphere = 0.46 m

Explanation:

First we need to find the volume of gold sphere:

Vg = (4/3)πr³

where,

Vg = Volume of gold sphere = ?

r = radius of gold sphere = 2 cm = 0.02 m

Therefore,

Vg = (4/3)π(0.2 m)³

Vg = 0.0335 m³

Now, we find mass of the gold:

ρg = mg/Vg

where,

ρg = density of gold = 19300 kg/m³

mg = mass of gold = ?

Vg = Volume of gold sphere = 0.0335 m³

Therefore,

mg = (19300 kg/m³)(0.0335 m³)

mg = 646.75 kg

Now, the volume of sand required for equivalent mass of gold, will be given by:

ρs = mg/Vs

where,

ρs = density of sand = 1602 kg/m³

mg = mass of gold = 646.75 kg

Vs = Volume of sand = ?

Therefore,

1602 kg/m³ = 646.75 kg/Vs

Vs = (646.75 kg)/(1602 kg/m³)

<u>Vs = 0.4 m³</u>

Now, for the radius of sand sphere to give a volume of 0.4 m³, can be determined from the formula:

Vs = (4/3)πr³

0.4 m³ = (4/3)πr³

r³ = 3(0.4 m³)/4π

r³ = 0.095 m³

r = ∛(0.095 m³)

<u>r = 0.46 m</u>

In vertebrates, most of the fluid that ultimately exits the body as urine first enters the nephron tubules by the process of ___
Talja [164]
The water and solutes the first enters the nephron tubules undergo a process just before it exits the body as a urine. This process is called filtration. It operates when 20 percent of the solution volume is filtered in the renal corpuscle at a given time. It is reportedly stated that there are around 180 liters of this fluid being filtered by the kidney every day.

A satellite is circling the moon (radius 1700 km) close to the surface at a speed v. A projectile is launched vertically up from
Elina [12.6K]

Answer:

 Rmax = 3.4 10⁶ m

Explanation:

For this exercise we will use the concept of energy

Initial. On the surface of the luma

    Em₀ = K + U

    Em₀ = ½ m v² - G m M / R_moon

Final. At the furthest point

    Emf = U

    Emf = - g m M / R_max

    Em₀ = Emf

    ½ m v² - G m M / R_moon = - G m M / R_max

    ½ v² + G M (-1 / R_moon + 1 / R_max) = 0           (1)

Let's use the fact that tells us that the speed of the rocket is equal to the speed of a satellite that rotates around the moon near the surface, let's use Newton's second law

        F = m a

Acceleration is centripetal

       a = v² / r

        r= R_moon

       G m M / R_moon² = m v² / R_mon

        G M / R_moon = v²

We substitute in 1

     ½ G M / R_moon + G M (1 / R_max - 1 / R_moon) = 0

    1 / R_max = 1 / R_moon (1- ½)

     R_max = R_moon 2

     Rmax = 2 1700 103

     Rmax = 3.4 10⁶ m

Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can mov
marusya05 [52]

If you want to maximize your potential energy, you can move the cart in any direction and get the same outcome because the distance it travels in each direction is equal.

The energy that a body possesses in its resting state is called its potential energy. The energy of a moving object is known as its kinetic energy. Stored energy that is conditional on the spatial orientation of the system's components; is also known as potential energy.

When a spring is either squeezed or stretched, the resulting increase in potential energy can be used to do work. Potentially, a steel ball has more energy in the air than it does when it hits the ground.

Here, we can observe that the carts are shifted to the right or left by one space. Consequently, the potential energy will also change in response to the motions.

To see a similar example:

#SPJ4

The right question is:

Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can move the carts to one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?

a. Moving the cart on Track 1 one space to the right (→).

b. Moving the cart on Track 2 one space to the left (←).

c. Moving the cart on Track 2 one space to the right (→).

d. All these movements will result in the same change in potential energy because they each move a cart the same distance.
