The law of conservation of energy states:



Energy increases exponentially with time


Total energy decreases due to energy output.


Energy cannot be created or destroyed.


Energy always remains in the same form.

Answers

Answer:

Energy cannot be created or destroyed.

Explanation:

its in the name, law of "conservation" of energy. energy can only change forms not be destroyed

Answer: Energy cannot be created or destroyed.

Explanation: The law of conservation of energy states that energy can neither be created nor be destroyed due to energy loss. It can only change its states from one energy state to another.

The efficiency is defined as the ratio of output work to the input work. The efficiency of the fan is not 100%. Because some of the energy is lost in the form of heat and sound. No machine is 100% efficient. There is always some loss of energy takes place.

Find the gravitational force between Venus (4.87 x 1024 kg) and
the sun (1.989 x 100 kg). Venus orbits at a distance of
1.082 x 10" m.

Answers

I agree 1.083 ....?jejebe you are

The gravitational force between Venus and the Sun, seperated at the distance of 1.082×10¹¹ m is 5.520×10²² N.

What is gravitational force?

Gravitational force is the attractive force between two bodies. It is applicable to all the bodies have masses and it is called as Universal law of gravitation.

Grarvitational force is the attractive force is directly proportional to the product of two masses and is inversely proportional to the square of distance between them.

F ∝ m₁ × m₂ / d², m₁ and m₂ is the mass of two bodies and is the distance between two bodies. The SI unit of mass is kg and SI unit of distance is m. The SI unit of force is newton.

From the gravitational force,

F = G (m₁×m₂ / d²)

G represents gravitational constant and is equal to 6.67× 10⁻¹¹ N.m²/kg².

From the given,

m₁ ( mass of venus ) = 4.87 x 10²⁴kg

m₂ ( mass of sun) = 1.989 x 10³⁰ kg

d² ( distance between sun and venus) = 1.082 x 10¹¹ m.

G = 6.67 ×10⁻¹¹ N.m² / kg²

F = G (m₁×m₂ / d²)

  = 6.67 ×10⁻¹¹ × 4.87 x 10²⁴× 1.989 x 10³⁰ / (1.082 x 10¹¹)²

 = 5.520 × 10²² N

The gravitational force between the venus and sun at the distance of  1.082 x 10¹¹ is 5.520× 10²² N.

Dietary fiber contains an indigestible material known as cellulite. This is false statement.

What is Dietary fiber?

Plant substances that are not broken down by human digestive enzymes are referred to as dietary fiber.

Only lignin and a few polysaccharides were recognized as meeting this criterion in the late 20th century, but resistant starch and oligosaccharides were listed as dietary fiber components in the early 21st century.

The phrase "all polysaccharides and lignin, which are not digested by the endogenous secretion of the human digestive tract" is commonly used to define dietary fiber.

At the moment, the majority of animal nutritionists either use a physiological definition, which states that "dietary components resistant to breakdown by mammalian enzymes," or a chemical definition, which states that "the sum of non-starch polysaccharides (NSP) and lignin."

Answers

Answer:

Option C. 83.8 J

Explanation:

From the question given above, the following data were obtained:

Mass (m) of object = 2 Kg

Velocity (v) of the object = 5 m/s

Height (h) = 3 m

Mechanical energy =.?

Next, we shall determine the kinetic energy of the object. This can be obtained as shown below:

Mass (m) of object = 2 Kg

Velocity (v) of the object = 5 m/s

Kinetic energy (KE) =?

KE = ½mv²

KE = ½ × 2 × 5²

KE = 1 × 25

KE = 25 J

Next, we shall determine the potential energy of the object. This can be obtained as shown below:

Mass (m) of object = 2 Kg

Height (h) = 3 m

Acceleration due to gravity (g) = 9.8 m/s²

Potential energy (PE) =.?

PE = mgh

PE = 2 × 9.8 × 3

PE = 58.8 J

Finally, we shall determine the mechanical energy of the object. This can be obtained as shown below:

Kinetic energy (KE) = 25 J

Potential energy (PE) = 58.8 J

Mechanical energy =?

Mechanical energy = KE + PE

Mechanical energy = 25 + 58.8

Mechanical energy = 83.8 J

What will happen when two neutral objects are rubbed together?

Answers

Answer:

I hope this will help you

Explanation:

When two neutral objects come into contact--especially in a dry environment--electrons can be knocked loose from one object and picked up by the other. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged. Objects with like charges repel each other, while those with opposite charges attract each other. This phenomenon--in which objects acquire an electric charge and exert a force on one another--is what we call static electricity.

. ........... is a mirror with a flat reflecting surface and is made of ordinary glass.

Answers

Answer:

Plane mirror.

Explanation:

A plain mirror is a mirror with a flat reflecting surface and is made of ordinary glass.

Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.

Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface such as a plane mirror.

Generally, the angle of reflection equals the angle of incidence when a light ray strikes or hits a plane mirror.

The properties or characteristics of the images formed by a plane mirror include;

I. They are virtual and erect (upright).

II. It is the same size as the object formed.

III. It has the same distance from the plane mirror as the distance of the object from the mirror.

Train A leaves the station heading north at 80 mph. At the same time and from the same station, Train B heads south 65 mph. How far apart are the trains after 3 hours fo travel?

Answers

Answer:

The trains will be 435 miles apart

Explanation:

Distance covered by the two trains can be obtained by multiplying their speeds with the time frame under consideration - in this our case, it is  3hours.

For Train A

Distance covered = 80mph X 3 hours = 240miles

For train B

Distance covered = 65mph X 3 hours = 195 miles.

The total distance between the two trains after 3 hours will be

240 + 195 = 435 miles

Explanation:

Given that,

The current in the wires of a circuit is 60.0 mA.

If the  voltage impressed across the ends of the circuit were  doubled and the resistance were tripled such that,

V' = 2V and R'=3R

The relation between current, voltage and resistance is given by :

V = IR

Let I' be the new current. So,

V'=I'R'

⇒ [tex]I'=\dfrac{V'}{R'}\\\\I'=\dfrac{2V}{3R}\\\\I'=\dfrac{2}{3}\times \dfrac{V}{R}\\\\I'=\dfrac{2}{3}\times I\\\\I'=\dfrac{2}{3}\times 60\\\\I'=40\ mA[/tex]

So, the new current would be 40 mA.
