Derived and define the units​

Answer:

p = 4000 kg-m/s

Explanation:

Given that,

The mass of a truck, m = 200 kg

Speed of the truck, v = 20 m/s

We need to find the momentum of the truck. The formula for momentum is given by :

p = mv

so,

[tex]p=200\times 20\\\\p=4000\ kg-m/s[/tex]

So, the momentum of the truck is equal to 4000 kg-m/s.

Answer:

Explanation:

A wave is a phenomenon that travels through a material medium without any permanent effect on the medium. It can be classified as mechanical or electromagnetic waves. And the two major types are transverse and longitudinal.

From the given question;

1. Longitudinal waves e.g sound waves, waves in a spring'

2. Frequency (number of cycles per second).

3. Wavelength of the wave. Measured in meters.

4. Transverse waves e.g light waves, water waves.

5. Wave speed.

6. Electromagnetic waves e.g ultraviolet waves, X-rays etc.

7. Amplitude.

8. Hertz.

9. Rarefaction

10. Compression

A wave is a phenomena that flows across a material medium without leaving any lasting mark.

1.Wave motion that is parallel to the wave direction is described

as longitudinal wave.

A wave is a phenomena that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify it. Transverse and longitudinal are the two main forms.

1.Wave motion that is parallel to the wave direction is described

as longitudinal wave.

2.Frequency is defined as the number of cycles per second.. The time to make one complete cycle is frequency.

3.Wavelength of the wave is measured in meters.The distance between successive crests of a wave is wavelength.

4. Examples of Transverse waves are light waves, water waves.. Wave motion that is perpendicular to wave direction describes transverse wave.

5.The number of waves that passes a given point in time is Wave speed.

6.Examples of Electromagnetic waves are ultraviolet waves, X-rays etc.

Electroimegnetic wave is a kind of wave that does not need a medium.

7.The highest point of a wave is called amplitude.

8.The unit for frequency is Hertz.

9. A region in a medium of longitudinal wave where molecules are Rarefaction.

10.  A region in a medium of longitudinal wave where molecules are

packed is called compression.

Answer:

the answer for the question is the last option

Answer:

B is the answer!!

Explanation:

1. All the relevant resistors are in series, so the total (or equivalent) resistance is the sum of the resistances of the resistors: 20 Ω + 80 Ω + 50 Ω = 150 Ω [choice A].

2. The ammeter will read the current flowing through this circuit. We can find the ammeter reading using Ohm's law in terms of the electromotive force provided by the battery: I = ℰ/R = (30 V)(150 Ω) = 0.20 A [choice C].

3. The voltmeter will measure the potential drop across the 50 Ω resistor, i.e., the voltage at that resistor. We know from question 2 that the current flowing through the resistor is 0.20 A. So, from Ohm's law, V = IR = (0.20 A)(50 Ω) = 10. V, which will be the voltmeter reading [choice F].

4. Trick question? If the circuit becomes open, then no current will flow. Moreover, even if the voltmeter were kept as element of the circuit, voltmeters generally have a very high resistance (an ideal voltmeter has infinite resistance), so the current moving through the circuit will be negligible if not nil. In any case, the ammeter reading would be 0 A [choice B].

Answer:

newton's 2nd  law

Explanation:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Answer:

Temperature, T2 = 300 Kelvin

Explanation:

Given the following data;

Initial volume = 100 Liters

Initial temperature = 200 Kelvin

Final volume = 150 Liters

To find the final temperature T2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

[tex] \frac {V}{T} = K[/tex]

[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]

Making T2 as the subject formula, we have;

[tex] T_{2}= \frac{V_{2}}{V_{1}} * T_{1}[/tex]

Substituting into the formula, we have;

[tex] T_{2}= \frac{150}{100} * 200[/tex]

[tex] T_{2}= 1.5 * 200 [/tex]

Temperature, T2 = 300 Kelvin

Nebulas

Explanation:

Nebulae are made of dust and gases—mostly hydrogen and helium. ... Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.

Answer:

The radius will be "100.31 m". A further solving is given below.

Explanation:

The given values are:

Time,

T = 2 minutes

i.e.,

 = 120 seconds

Speed,

V = 5.25 m/s

As we know

⇒  [tex]T=\frac{2 \pi R}{V}[/tex]

then,

⇒  [tex]R=\frac{TV}{2 \pi}[/tex]

On substituting the given values, we get

⇒      [tex]=\frac{120\times 5.25}{2\times 3.14}[/tex]

⇒      [tex]=\frac{630}{6.28}[/tex]

⇒      [tex]=100.31 \ m[/tex]

Answer:

P2 = 6.67 atm

Explanation:

Given the following data;

Initial volume = 1 Liters

Initial pressure = 5 atm

Final volume = 0.75 Liters

To find the final pressure P2, we would use Boyles' law.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

[tex] PV = K[/tex]

[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]

Substituting into the equation, we have;

[tex] 5 * 1 = P_{2} * 0.75 [/tex]

[tex] 5 = 0.75_{2} [/tex]

[tex] P_{2} = \frac {5}{0.75}[/tex]

[tex] P_{2} = 6.67[/tex]

P2 = 6.67 atm

Therefore, the new pressure is 6.67 atm.
