PHYSICS HELP PLEASE ONE QUESTION 10 POINTS:)

Answers

Answer 1

Case 1 has the greatest strength for the push and pull. Option A is correct.

What is force?

The pushes and pulls the body experiences are referred to as force. It can occasionally be used to alter the body's size, shape, and direction.

Mass times acceleration equals force, according to the definition. Newton is its measure.

The force transmitted through a rope, string, or wire as it is tugged by opposing forces is referred to as the tension force.

Energy is drawn equally from both ends by the tension force, which is exerted along the whole length of the wire.

The tension force is acting in the rope causing greater strength for the push and pull.

Hence, option A ia correct.

Any organic, living system that performs as an independent unit is referred to as an organism. Cells comprise all living things. Multicellular mammals, plants, and fungi are examples of multicellular creatures. Unicellular microorganisms include bacteria and archaea.

All kinds of creatures can have the capacity for procreation, growth and development, maintenance, and to some extent, stimulus-response. Multicellular organisms such as beetles, tetrapods, mushrooms, and vascular plants grow a variety of tissues and organs.

Dos masas de 8kg es tan unidas en el extremo de una varilla de aluminio de 400mm de longitud. La varilla está sostenida en su parte media hora en círculos y solo puede soportar una tensión máxima de 800 N ¿cuál es la frecuencia máxima de revolución

Answers

Answer:

The maximum frequency of revolution is 3.6 Hz.

Explanation:

Given that,

Mass = 8 kg

Distance = 400 mm

Tension = 800 N

We need to calculate the velocity

Using centripetal force

[tex]F=\dfrac{mv^2}{r}[/tex]

Where, F= tension

m = mass

v= velocity

r = radius of circle

Put the value into the formula

[tex]800=\dfrac{8\times v^2}{200\times10^{-3}}[/tex]

[tex]v^2=\sqrt{\dfrac{800\times200\times10^{-3}}{8}}[/tex]

[tex]v=4.47\ m/s[/tex]

We need to calculate the maximum frequency of revolution

Using formula of frequency

[tex]f=\dfrac{v}{2\pi r}[/tex]

Put the value into the formula

[tex]f=\dfrac{4.47}{2\pi\times200\times10^{-3}}[/tex]

[tex]f=3.6\ Hz[/tex]

Hence, The maximum frequency of revolution is 3.6 Hz.

What are the relationships between the different wave properties (frequency, wavelength, wave speed, period, amplitude)
Ex) As ___ increases, ___ increases/decreases/remains the same.

Answers

Answer:

As frequency (cycles per second) increases the wavelength decreases.

As frequency increases the period also decreases

If wave speed or velocity increases, so too does the frequency

Amplitude of a wave is totally independent of frequency, period etc.  So it remains the same as frequency shifts.  Like FM radio the amplitude remains the same as the frequency of the broadcast modulates.

Explanation:

F= 1/t  Frequency is inversely proportional to time (wavelength)

Period is the time it takes for one wave cycle to complete   Period is 1/f

++++++++++++++++++++++++++++++++++++

vw=λT  Speed of propagation vw= wavelength x T time

vw=fλ  Knowing frequency multiply times wavelength to get wave speed.

++++++++++++++++++++++++++++++++

Amplitude varies only as the energy applied varies.  Like transmission power, in a 60 hz power feed the amplitude can be 120, 230, 460 volts (note these nominal amplitudes are RMS root mean squared  or .707 of the peak of the waveform).

An object is dropped from 20. meters above the moon. The acceleration due to gravity on the moon is 1.62 m/s^2
a. How long does it take for the object to impact the moon?
b. At what speed does it impact the moon?

Answers

Answer:

a. Approximately  3.21 seconds

b. Approximately  5.196 m/s

Explanation:

a. The height from which the object is dropped = 20 meters

The location of the occurrence = The moon

The acceleration due to gravity on the moon  = 1.62 m/s²

The time it took the object to to impact the moon is given by the equation of free fall as follows;

h = 1/2·a·t²

Where;

h =The height from which the object is allowed to freely fall = 20 meters

a = The acceleration due to gravity on the moon  = 1.62 m/s²

t = The time of motion of the object

Substituting the values, gives;

20 = 1/2 × 1.62 × t²

t² = 20/(1.2 × 1.62) ≈ 10.23 s²

t = √ 10.23 ≈ 3.21 s

The time in motion of the object before impact, t = 3.21 seconds

b. The final speed, v is given from the equation for speed under free fall, which is presented as follows;

v = u + a·t

Where

u = The initial vertical velocity = 0

Substituting the values gives;

v = 0 + 1.62 × 3.21 ≈ 5.196 m/s

The final speed, v with which the object impacts the moon ≈ 5.196 m/s

Answers

Two statements describe reasons a solar cell must contain semiconductors :

A. Semiconductors form a path for the electrons that are released by the photoelectric effect.

C. Semiconductors serve as a source of electrons to form an electrical current.

What is Photoelectric effect?

Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.

When the semiconductor is exposed to light, it absorbs energy and transfers it to the material, due to which energy reaches to negatively charged particle (electron), which allows the electron to flow in the material as electric current .

hence , correct option will be :

A. Semiconductors form a path for the electrons that are released by the photoelectric effect.

C. Semiconductors serve as a source of electrons to form an electrical current.

Typically, people think of a lava flow when they think of volcanoes. However, some eruptions are mostly ash and steam released into the atmosphere. This type of volcanic eruption is blamed for causing what is referred to as a "Little Ice Age" starting in the 13th century. The ash and steam blocked the sun's rays causing extreme cold and agricultural difficulty which lead to massive decreases in populations.

Remi travels 160 meters in 4 seconds. What was Remi's initial speed if her final velocity was 6.9 m/s?

Answers

Answer:

73.1 m/s

Explanation:

Given:

Δx = 160 m

v = 6.9 m/s

t = 4 s

Find: v₀

Δx = ½ (v + v₀) t

160 m = ½ (6.9 m/s + v₀) (4 s)

v₀ = 73.1 m/s
