Regular reflections occurs when light reflects off a very smooth surface and forms a clear image.
Diffuse reflection: occurs when light reflects off a rough surface and forms a blurry image or no image at all.

Similarities: they both hit the surface, but the difference is one of them give clear image the other one gives blurry image or no image at all.

Hope this helped!

Which of the following is an advantage of circuit breakers over fuses.

A.) It is easier to trip a fuse.

B.) Circuits get hot.

C.) Tripped circuit breakers do not need to be replaced.

D.) Fuses need to be replaced

Answers

I’m sure the answer is C

One of the advantage of circuit breaker over fuses is tripped circuit breakers do not need to be replaced as fuse does power is in rapid restoration  with breakers.

What are circuit breakers?

A circuit breaker is an electrical device similar to electrical switches designed to protect the circuit from damges created by over current or short circuit.

Circuit breakers can be operated manually or automatically  for saving the electrical network and components.  Fuse is another saftey device to provide protection from overcurrent. It is operating automatically and it melts when over current is passed.

Even though fuses can be easily operated and less expensive, power cannot be restored after tripping the fuse whereas,  tripped circuit breakers need not be replaced and easily restore the energy as soon.

Chemical changes occur as energy is transferred when molecules- - or - to form one or more new substances

Answers

Answer:

Correct options are C. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies.

D. Energy stored in organic fuels are used for heat and electricity/ When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy.

Explanation:

The breakdown of food leads to the release of chemical energy which was first stored in food. This energy is used to drive necessary functions of the body. A series of chemical reactions are involved in the breakdown of food and changing them into useful components for the cell.

Chemical energy is stored in circuits. When the battery is connected to a circuit, the chemical energy gets transferred into electrical energy.

What volume of silver metal will weigh exactly 2500.0 g. The density of silver is 10.5 g/cm³

Answers

Answer:

Explanation:

Density = mass/volume

132g/(48.9 cm³) = 2.7 g/cm³

(27 g)/(3 cm³) = 9 g/cm³

512 g/(65 cm³) = 7.9 g/cm³

1.2 kg/(3243 cm³) cm³ = 1200 g/(3243 cm³) = 0.37 g/cm³

The diagram below shows a wave. The feature of the wave are labeled A, B, C, and D. Which label identifies the wavelength?​

Answers

The answer would be c

According to the given diagram, the c identifies the wavelength of the curve. Hence, option C is correct.

What is wavelength?

In order to characterize waveform signals that are transmitted across wires or into space, the term "wavelength" is used to refer to the separation between two identical positions (adjacent crests) in succeeding cycles. Typically, this length in wireless systems is measured in meters (m), centimeters (cm), or millimeters (mm) (mm). When describing the wavelength of infrared (IR), visible light (UV), and gamma radiation, units of 10-9 nanometers (nm) or angstroms (10-10 m) are more usually used.

The relationship between frequency and wavelength is inverse, with frequency being the number of wave cycles per second. A signal's wavelength shortens as its frequency rises, or we may say that the relationship between wavelength and refractive index is inverse.
