Physics
1 answer:
IceJOKER [234]3 years ago
3 0

Answer:

A Mold

Explanation:

A mold forms when hard parts of an organism are buried in sediment; the hard parts completely dissolve over time, leaving behind a hollow area. A cast forms as a result of a mold when minerals and sediment fill in the impression.

A spring with k = 53 N/m hangs vertically next to a ruler. The end of the spring is next to the 18 cm mark on the ruler. If a 2.
Anarel [89]

Answer:

1.07 m

Explanation:

x = Compression of the spring

k = Spring constant = 53 N/m

Initial length = 18 cm

P = Kinetic energy

K = Kinetic energy

At the lowest point of the mass the energy conservation is as follows

P_{ig}+P_{is}+K_i=P_{fg}+P_{fs}+K_f\\\Rightarrow mgx+0+0=mgx+\frac{1}{2}kx^2\\\Rightarrow x=\frac{2mg}{k}\\\Rightarrow x=\frac{2\times 2.4\times 9.81}{53}\\\Rightarrow x=0.89\ m

At its lowest position the mark on the ruler will be

x_f=0.18+0.89\\\Rightarrow x_f=1.07\ m

The spring line will end up at 1.07 m

An electron with an initial speed of 660,000 m/s is brought to rest by an electric field. What was the initial kinetic energy of
GREYUIT [131]

Answer:

Kinetic energy of the electron E_k=1.23\ eV

Explanation:

It is given that,

Initial speed of an electron, u = 660000 m/s

Final speed of the electron, v = 0 (at rest)

The kinetic energy of an electron is possessed due to the motion of an electron. The mathematical formula for the kinetic energy is given by :

E_k=\dfrac{1}{2}mv^2

m is the mass of electron

E_k=\dfrac{1}{2}\times 9.1\times 10^{-31}\times (660000)^2

E_k=1.98\times 10^{-19}\ J

Since, 1\ eV=1.602\times 10^{-19}\ J

E_k=\dfrac{1.98\times 10^{-19}}{1.602\times 10^{-19}}

E_k=1.23\ eV

So, the initial kinetic energy of the electron is 1.23 eV. Hence, this is the required solution.

The ____ is a wedge-shaped thickening in the middle layer of the eyeball that controls the shape of the lens.
Yanka [14]

The ciliary body is a wedge-shaped thickening in the middle layer of the eyeball that controls the shape of the lens.

The ciliary body is a section of the middle layer of the eye's wall. It is located behind the iris.  It includes a ring-shaped muscle that modifies the curvature of the lens when the eye focuses.

Additionally, it creates the transparent liquid that fills the area between the iris and the cornea. Aqueous humor is the name of this fluid in the eye.

It also contains the ciliary muscle, which modifies the lens' shape when your eyes focus on a close object.

The anterior pars plicata and the posterior pars plana are two parts of ciliary body. The anterior vitreous comes into contact with the pars plana, which creates a smooth surface. The ciliary processes, which are 70–80 radiating ridges, are produced by the pars plicata.
