Answer:

Red has the lowest energy and violet the highest. Beyond red and violet are many other kinds of light our human eyes can't see, much like there are sounds our ears can't hear. On one end of the electromagnetic spectrum are radio waves, which have wavelengths billions of times longer than those of visible light.

Answer:

gas

Explanation:

because water become gas when above 100 celcius

Answer:

Gaseous (vapor) state

Explanation:

Because the boiling point of water is 100 C, then anything above that temperature would mean it remains in the vapor state.

Answer:

electromagnetic radiation

Answer:

The center of mass can be calculated by taking the masses you are trying to find the center of mass between and multiplying them by their positions

Answer and Explanation:

The law of conversation of energy states that energy cannot be created or destroyed. The pendulum slows down and stops eventually not because the kinetic energy is destroyed, but it is transferred into sound and heat energy instead because there is air resistance and friction.

Kinetic energy => Gravitational potential energy (Loop but some energy transferring to heat and sound each time)

Answer:

20g/ml

Explanation:

the mass must be in gram and 90-60 =30

so 600g/30ml =20g/ml

Answer:

Explanation:

Diffraction, as the waves spread out (specifically spread to the whole house) by passing the door.

Answer:

only E is true

Explanation:

A) to find out if it would fall 4x as fast by 2x the time we can look at the formula for free fall:

for free fall the Y = [tex]\frac{1}{2}[/tex]g[tex]t^{2}[/tex] where Y is the distance fallen, g is gravity and t is time

so since the rate at which an object falls is the same (gravity stays the same) it will not fall faster with any alteration

B) An object would fall half the distance if you double the time

here we may need to check with an example:

lets say we fall for 2 seconds in the first and 4 in the second:

Y= 1/2 (9.8) (2)^2 gives 19.6m fallen

Y= 1/2 (9.8) (4)^2 gives 78.4m fallen

from this we can see that doubling the time does not half the distance

C) all objects fall at the same rate no matter their mass so this statement is false

D) from the example above we see again that doubling time does not double the distance

E) this statement is true

Option e is correct. So that a 2 kg object falls as fast as a 1 kg object. Height attained depends upon the time factor.

The vertical distance between the object's top and bottom is defined as height. It is measured in centimeters, inches, meters, and other units.

The height attained during free fall ;

[tex]\rm H = ut + \frac{1}{2}gt^2 \\\\ u = 0 \\\\ H=\frac{1}{2}gt^2[/tex]

The height attained during free fall is independent of the mass. Due to that, a 2 kg object falls as fast as a 1 kg object.

Hence,option e is correct.

Answer: Seatbelts relate to Newton's first law of motion because in the case of a car accident, someone in the car would continue forward until they hit somethng else. A seat belt will help prevent this because it will push back on you (action-reaction force).

Explanation:

1) wavelength is 2

6m is 3 wavelengths so 6 = 3.. to find for one wavelength divide both sides by 3

6 = 3

2(m) = 1(wavelength)

2) amplitude is half of what they've given

2/2 = 1m

3) f = 1/t

time period = 1.5s for 3 wavelengths

time period for one wavelength is 1.5/3 = 0/5

so f = 1/0.5 = 2 Hz

Answer: True

The late collisions would be observed on the half-duplex end of this type of connection. It occurs when a connection there are two duplex formats.

A duplex mode is a type of Ethernet network capable of sending and receiving data simultaneously.

A duplex connection device is an approach in which point-to-point connection data are transmitted in both directions.

In a duplex connection, data are transmitted at the same time simultaneously (duplex) and/or in one direction at each time (half-duplex).

The displacement needed by the airplane to return to its starting point is 12.53 km.

From the question, we are to determine the displacement

Using the diagram attached, D is displacement

Using the Pythagorean theorem,

D² = 11² + 6²

D² = 121 + 36

D² = 157

D = √157

D = 12.53 km

Hence, the displacement needed by the airplane to return to its starting point is 12.53 km.

Electric field simply means an electric property that is associated with each point in a space when there is a charge present.

Your information is incomplete. Therefore, an overview of an electric field will be given.

An electric field simply means the physical field that surrounds particles that are electrically charged.

It should be noted that the electric field exerts force on the other charged particles that are in the field by either attracting or repelling them.

In conclusion, the SI unit of an electric field is volts per meter. This is also equivalent to Newton's per coulomb.
