Answer:

\huge\boxed{\sf Hen's \ Egg}

Explanation:

Seen with an unaided eye means that is visible to the naked eye.

So,

Hen's Egg can be seen with an unaided eye.

However, Red Blood Cells (RBCs) and Sperm cells need a microscope for them to be seen!

The pressure at the bottom of a jug filled with water does NOT depend on the
pickupchik [31]

Answer:

D) surface area of the water

Explanation:

The pressure at the bottom of a column of fluid is given by Stevino's law:

p=\rho g h

where

p is the pressure at the bottom of the column

\rho is the density

g is the acceleration due to gravity

h is the depth of the liquid

So, we see that the pressure at the bottom of a jug filled with water depends on all these quantities:

A) depth of the liquid

B) acceleration due to gravity

C) density of water

While it does not depend on:

D) surface area of the water

If this standing wave is 48.8 meters long from end to end, what is the wavelength?
Mrrafil [7]

The wavelength of a standing wave is 8.13 m.

<h3>What is a wavelength?</h3>

The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.

The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.

The given data in the problem is;

String length(L)= 48.8 metere

Wavelength(λ)=?

The length of the wave having n nodes is found as;

L=nλ

Substitute the given value;

48.8 = 6λ

λ= 8.13 m

Hence, the wavelength of a standing wave is 8.13 m.

To learn more about the wavelength, refer to the link;

A force in the +x-direction with magnitude F(x)=18.0N−(0.530N/m)x is applied to a 8.90 kg box that is sitting on the horizontal,
Lady_Fox [76]

Answer:

6.875 m/s

Explanation:

The force is variable which is given by

F(x) = 18 - 0.53 x

mass of the box, m = 8.9 kg

initially it is at rest at x = 0

Let the velocity is v after travelling a distance of 15 m.

According to the work energy theorem, the work done by all the forces is equal to the change in kinetic energy of the body.

Work done = change in kinetic energy

\int \overrightarrow{F}.d\overrightarrow{x}=\Delta  K.E

\int_{0}^{15} \left ( 18-0.53 x \right )dx=\frac{1}{2}\times m \left ( v^{2}-u^{2} \right )

\left ( 18x-0.265x^{2} \right )_{0}^{15}=\frac{1}{2}\times 8.9\times  \left ( v^{2}-0^{2} \right )

18 x 15 - 0.265 x 15 x 15 = 4.45 x v²

270 - 59.625 = 4.45 v²

v² = 47.275

v = 6.875 m/s

Thus, the final velocity of the box is 6.875 m/s.
