radio waves,X-rays,

Explanation:

In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.

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

Answer:

they amplitude modulation

and they ferequency modulation

Explanation:

The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.

Answer:

The free-body diagram of the cannonball is found in the attachment below

Note The question is incomplete. The complete question is as follows:

A cannonball has just been shot out of a cannon aimed 45∘ above the horizontal rightward direction. Drag forces cannot be neglected.

Draw the free-body diagram of the cannonball.

Explanation:

Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation.

In order to construct free-body diagrams, it is important to know the various types of forces acting on the object in that situation. Then, the direction in which each of the forces is acting is determined. Finally the given object is drawn using any given representation, usually a box, and the direction of action of the forces are represented using arrows.

In the given situation of a cannonball which has just been shot out of a cannon aimed 45∘ above the horizontal rightward direction., the forces acting on it are:

F = force exerted by the cannon acting in the direction of angle of projection

Fdrag = drag force. The drag force acts in a direction opposite to the force exerted by the cannon

Fw = weight of the cannonball acting in a downward direction

The free body diagram is as shown in the attachment below.

4.  Density of water = 1.01g/ml

6:  Mass of silver = 892.5g

8:  Mass of 157.8g  I gave the answer as mass, even though it asked for weight.

Answer:

See explanation

Explanation:

Hookes law states that; the displacement due to a stretching force is directly proportional to the magnitude of the deforming force.

F = ke

F = deforming force

k = force constant

e = extention

k = F/e

k = 4N/0.06 m= 66.67 Nm^-1

To determine the extension of the spring produced by the 4.0 N weight

1) We measure the original length of the spring

2) We measure the length after hanging the 4 N mass

3) Subtract the new length from the original length to determine the extention.

Red shirt appears red because:

a. The shirt reflects red light

A red shirt appears red because the shirt reflects red light.

Thus, An important topic for astronomers is "red shift." The phrase can be taken literally; when the light's wavelength is extended, the light is perceived as having "shifted" toward the red portion of the spectrum.

When a source of sound moves in relation to an observer, sound waves experience a similar phenomenon.

The frequency of sound waves varies if the source of the sound and the observer are moving relative to one another, according to Austrian mathematician Christian Andreas Doppler, who made this discovery.

The observer hears a frequency that is higher when the two are moving closer together and lower when they are moving farther apart and red shift.

Thus, A red shirt appears red because the shirt reflects red light.

Answer: A.The ocean is colder than the land

Explanation:

Based on the information provided in the question, we are informed that Agustin visits Panama City, Florida, during the month of May and that he feels a shore breeze blowing from the ocean onto the beach.

The reason for the shore breeze is simply due to the fact that the ocean is colder than the land. Since the ocean is colder, anyone who goes to the beach will feel the breeze.

The final velocity of the bus  is 9.83 m/s

The given parameters;

initial velocity of the bus, = 30 km/h

constant increase in speed, = 1.5 m/s

time of motion, t = 6.8 s

The initial velocity of the bus in m/s;

[tex]v = 30 \frac{km}{h} \times \frac{1000 \ m}{1 \ km} \times \frac{1 \ h}{3600 \ s} = 8.33 \ m/s[/tex]

The acceleration of the bus;

[tex]a = \frac{\Delta v}{\Delta t} = \frac{1.5 \ m/s}{6.8 \ s } = 0.22 \ m/s^2[/tex]

The final velocity of the bus at the given time of motion;

[tex]v= u + at\\\\v = 8.33 + (0.22 \times 6.8)\\\\v = 9.83 \ m/s[/tex]

Thus, the final velocity of the bus  is 9.83 m/s

Answer: The correct statement is D (the sodium azide breaks down into sodium and nitrogen gas).

Explanation:

A chemical change is an irreversible chemical reaction in which new substances are usually formed. It is also defined as chemical decomposition of a substance leading formation of two or more other substances. A typical example is in the break down or decomposition of sodium azide into sodium metal and nitrogen gas. This is seen in the chemical balanced equation below:

2 NaN3 --> 2 Na + 3 N2

Sodium azide ( also called Sodium trinitride) is a chemical compound that is in built into automobile air bags which upon collision is being triggered to decompose. This leads to the generation of sodium and nitrogen gas that fills the air bag. This aid ls in reducing the impact of the collision and absorbs the forward-moving energy of the occupant.

Red Riot out

Answer:

Explanation:

From the question

Weight of painter = 500N

Weight of scaffold = x

Weight of painter + weight of scaffold = 2* 400 (since they are supported by two ropes)

Substitute

500 + x = 2(400)

500+x = 800

x =  800-500

x = 300N

Hence the weight of the  scaffold is 300N

A force is a push or pull on an object. Forces usually cannot be seen but their effects can.

Nothing moves, changes speed, stops or changes direction without force. Heavier objects need more

Answer:

P = 21 watts

Explanation:

Given that,

Weight of a package, F = 35 N

Distance, d = 18 m

Time, t = 30 s

We need to find the power required to carry the package. Power is equal to the work done divided by time. So,

[tex]P=\dfrac{W}{t}\\\\P=\dfrac{Fd}{t}\\\\P=\dfrac{35\times 18}{30}\\\\P=21\ W[/tex]

So, the required power is 21 watts.
