Answer:

C). Buzzer

Explanation:

In electric buzzer is a device which produce sound of high amplitude when electric current flows through it.

As per the concept of energy we know that the electrical energy when given to the buzzer then the electrical energy is converted into sound energy.

So here we can say that the correct answer here is

C).Buzzer

while in other options

B) Motor : Electrical energy is converted into mechanical energy

D) Bulb : electrical energy is converted into light energy

E) Battery : Chemical energy is converted into electrical energy

An airplane cabin is pressurized to 570 mmhg. what is the pressure inside the cabin in atmospheres?
abruzzese [7]
1 atm corresponds to 760 mmHg, so we can set up a simple proportion to find how many atmospheres correspond to 570 mmHg:
1 atm: 760 mmHg = x: 570 mmHg
and from this, we find
x= \frac{1 atm \cdot 570 mmHg}{760 mmHg} =0.75 atm

A 94.7 kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.75 r
Marta_Voda [28]

Answer:

The angular velocity of the platform is 1.114 rad/s.

Explanation:

Step 1:  Given data

Mass of the horizontal circular platform = 94.7 kg

Mass of the monkey = 21.1 kg

Initial angular velocity = 1.75 rad/s

A monkey drops a 9.25 kg bunch of bananas

They hit the platform at 4/5 of its radius from the center

Model the platform as a disk of radius 1.63 m

Step 2: Calculate the moment of inertia of the disk

I = ½ * m * r² = ½ * 94.7 * 1.63² = 125.80

Step 3: Calculate the initial angular momentum

I = 125.80 * 1.75 = 220.15

Step 4: Calculate the moment of inertia for the bananas

For the bananas, r = 4/5 * 1.63 = 1.304 m

I = 9.25 * 1.304² = 15.73

Step 5: Calculate Moment of inertia for the monkey

I = 21.1 * 1.63² = 56.06

Step 6: Total moment of inertia = 125.80 + 15.73 + 56.06 = 197.59

Step 7: Calculate final angular momentum = 197.59 * ω

197.59 * ω = 220.15

ω = 220.15 / 197.59

This is approximately 1.114 rad/s.

How does the physical structure of a plant have<br> Large leaves help it survive?
elena-14-01-66 [18.8K]

The large leaves help it survive as they serve as the<u> organ for photosynthesis.</u>

Explanation:

  • Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy.
  • During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds
  • Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food.
  • Through pores, or stomata, leaves breathe in carbon dioxide and breathe out oxygen. Leaves also release excess water.
  • Most leaves are broad and so have a large surface area allowing them to absorb more light
  • A thin shape means a short distance for carbon dioxide to diffuse in and oxygen to diffuse out easily.
  • The exchange of oxygen and carbon dioxide in the leaf occurs through pores called stomata.
  • Normally stomata open when the light strikes the leaf in the morning and close during the night.

Which statement BEST describes how the body moves?
Alex73 [517]
<h3><u>Answer;</u></h3>

A. Skeletal muscles, which are made of fibers, nerves, and blood vessels, contract in order to make the body move.

<h3><u>Explanation</u>;</h3>
  • <em><u>Muscular tissues functions in movement and locomotion through its direct connection with the skeletal system. </u></em>
  • <em><u>Skeletal muscles are responsible for moving the body. The skeletal muscle contractions pull on tendons, which as attached to bones. When the skeletal muscle contraction causes the muscle to shorten, the bone and thus the body par will move. </u></em>
  • <em><u>Skeletal muscles also provide structural support for the entire body. </u></em>
