Explanation:

It is a true statement that the idea that all matter consists of elements was first introduced a few hundred years ago.

Anything which has mass and occupies space is known as matter, mainly there are four states of matter solid liquid gas, and plasma.

These different states of matter have different characteristics according to which they vary their volume and shape.

Individuals have believed that earth, air, water, and fire are the only four elements that make up matter for roughly two thousand years.

For more than two thousand years, Aristotle's theory that all matter is composed of just four elements was accepted, but only around 500 years ago did scientists begin to find all of the elements that are currently recognized.

Beginning around five hundred years ago, scientists started learning about all of the elements that are currently recognized.

Answer:

55N

Explanation:

Impulse is the product of Force and Time

Impulse = Force * Time

Given

Impulse = 550Ns

Time = 10s

Force = Impulse/Time

Force = 550/10

Force = 55N

Hence the net force on the scooter is 55N

Answer:

I would say false

Explanation:

Because friction slows it down which means when the object bounces back it will not have the same energy or force that was applied before.

Answer:

The force that pulls the car down is Wₓ = 14052.6 N and the one that pushes the car up is F = 26552.6 N

Explanation:

For this exercise we will use Newton's second law, let's set a reference system where the x axis is parallel to the plane, in the adjoint we can see the forces in the system.

           sin  35 = Wₓ / W

            cos 35 = W_y / W

            Wₓ = W sin 35

            W_y = W cos 35

            Wₓ = 2500 9.8 sin 35

             Wₓ = 14052.6 N

let's write the equations for each axis

and

Y axis  

       N-W_y = 0

       N = W_y

X axis  

       F -Wₓ = m a

       F = Wₓ + m a = mg sin 35 + m a

       F = m (a + g sin 35)

let's calculate

       F = 2500 (5 + 9.8 sin 35)

       F = 26552.6 N

The force that pulls the car down is Wₓ = 14052.6 N and the one that pushes the car up is F = 26552.6 N

I hope my answer can help you

Answer: The answer would be C

Explanation:

d) Has a typo and c) is the right answer. It tells us what the technician is doing

Answer:

As the Sun ages it will enter another stage of stellar evolution where it's atmosphere begins to inflate.As the Sun heats up and expands, life on Earth will become increasingly difficult. Long before the Sun becomes a red giant some 4 or 5 billion years from now, our planet will be rendered uninhabitable.

Answer:

1. Compact units containing optical components such as bandpass filters and dichroic mirrors. For example, a low cost fluorescence or confocal microscope can be built by combining a laser, optical blocks, and microscope objective lenses.

2. The lateral displacement is directly proportional to the thickness of the glass slab. When the light enters a glass slab,the light rays are refracted. Now,the lateral displacement is the final distance between the incident ray and the emergent ray

Answer:

amplitude

Explanation:

amplitude of a wave is the maximum displacement of a point from its rest position.

Answer:

F = 12.52 N

Explanation:

Given that,

Charge, q₁ = -2 C

Charge, q₂ = 5 C

The distance between charges, d = 84,752 m

We need to find the force between the two charges. The force between two charges is given by :

[tex]F=k\dfrac{q_1q_2}{d^2}\\\\F=9\times 10^9\times \dfrac{2\times 5}{(84752)^2}\\F=12.52\ N[/tex]

So, the force between charges is 12.52 N.

Answer:

Bowling Ball: weight on Earth = 49 N

Textbook: Mass = 2 kg; weight on the moon = 3.2 N

Large dog: weight on Earth = 490 N; weight on the moon = 80 N

Law of Universal Gravitation: [tex]F_{G}=\frac{Gm_{1}m_{2}}{r^{2}}[/tex]

[tex]F_{G}[/tex] = gravitational force (Newtons/N)

G = gravitational constant, 6.67430 × 10¹¹ [tex]\frac{N*m^{2}}{kg^{2}}[/tex]

m₁ and m₂ = masses of two objects (kilograms/kg)

r² = square of distance between centers of the two objects (meters/m)

Explanation:

not really sure

Answer:

=57600joules

Explanation:

Given data

Velocity =0.8m/s

Time = 30*60=1800 seconds

Distance =Velocity x time

Distance =0.8*1800

Distance =1440m

Work done = force x distance

Work done =40*1440

Work done =57600joules

Hence the work Done is 57600joules

Rectilinear motion of light is shown in picture. The wavelengths of light that are visible to humans fall into a relatively small range within that wide spectrum.

Electromagnetic radiation that the human eye can detect as light. From radio waves with wavelengths measured in meters to gamma rays with wavelengths shorter than roughly 1 1011 meter, electromagnetic radiation occurs throughout a very broad range of wavelengths.

The wavelengths of light that are visible to humans fall into a relatively small range within that wide spectrum, ranging from about 700 nanometers (nm; billionths of a meter) for red light to roughly 400 nm for violet light. Infrared and ultraviolet are two spectral bands that are close to the visible region and are repeatedly alluded to as light as well. Rectilinear motion of light is shown in picture.

Therefore, rectilinear motion of light is shown in picture.

Answer:

I known this much much except c and d. Hope this helps, thank you !!

formula: m1 * d1 = m2 * d2

datos:

m1= 45 kg

d1= 160 cm

m2= 38 kg

d2= x

reemplazamos datos en formula:

45kg * 160cm = 38kg * d2

El 38 pasa al otro lado de la igualdad a dividir:

(45kg * 160cm) / 38 kg = d2

Resolvemos: (kg se cancela con kg, quedando solo los cm)

7200cm / 38 = d2

Resultado:

d2 = 189.5 cm

Answer: Car C

Explanation:

Answer:

It is important to have a range of tools that can measure all parts of the electromagnetic spectrum because electromagnetic spectrum have different radiations such as infrared, visible light, ultraviolet, radio waves, microwaves, X-rays and gamma rays. Each of these radiation requires different instrument for their measurement. So that's why a range of tools are needed to measure electromagnetic spectrum.
