Answers
Answer:
A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.
Explanation:
Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).
The period is the time that elapses between the emission of two consecutive waves. In other words, it is the time it takes for a complete wave to pass a reference point. The period (T) is simply the inverse of the frequency (f):
[tex]T=\frac{1}{f}[/tex]
In this case, f=5*10¹⁰ Hz. So, replacing in the definition of period T:
[tex]T=\frac{1}{5*10^{10} Hz }[/tex]
Solving:
T= 2*10⁻¹¹ seconds
A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.
A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.
What is fequency?
The fequency is defined as the number of cycles achieved by the any wave it is expressed in hertz.
Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).
The period is the time that elapses between the emission of two consecutive waves. In other words, it is the time it takes for a complete wave to pass a reference point. The period (T) is simply the inverse of the frequency (f):
[tex]T=\dfrac{1}{f}[/tex]
In this case, f=5*10¹⁰ Hz. So, replacing in the definition of period T:
[tex]T=\dfrac{1}{5\times 10^{10}}=2\times 10^{-11}\ Sec[/tex]
A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.
Thus a microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

Incandescent solids emit scattered spectra; incandescent gases emit continuous spectra.
Answers
Answer:
ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.
Explanation:
Materials when heated emit a continuous spectrum with all wavelengths.
Hot gas gases emit a spectrum that depends on the transitions between atomic states, therefore it is a discrete spectrum.

A graduate student is trying to follow the weather on Jupiter for her PhD thesis. To see the big weather patterns in the upper atmosphere of the planet, she needs to have excellent resolution. What type of telescope would be best for her to use? a. a refractor, with as small an aperture as possible b. a radio telescope c. a large reflector in an observatory located at sea level d. a large reflector located in orbit above the Earth's atmosphere e. you can't fool me, all these telescopes have the same resolution
Answers
Answer: large reflector located in orbit above the Earth's atmosphere
Explanation:
Since the student wants to see the big weather patterns in the upper atmosphere of the planet, and she will therefore need to have excellent resolution, the type of telescope that is ideal for her to use is a large reflector located in orbit above the Earth's atmosphere.
It should be noted that the refractor or a radio telescope isn't ideal in this situation as they will not capture the bug weather pattern and doesn't have an excellent resolution like the large reflector.

A 150kg motorcycle starts from rest and accelerates at a constant rate along with a distance of 350m. The applied force is 250N and the coefficient of kinetic friction is 0.03. What is the net force applied to the motorcycle?
Answers
Answer:
205N
Explanation:
The net force (F) is the difference between the applied force([tex]F_{A}[/tex]) and the kinetic frictional force([tex]F_{R}[/tex]). i.e
F = [tex]F_{A}[/tex] - [tex]F_{R}[/tex] -----------------(i)
Note that;
[tex]F_{R}[/tex] = μmg
Where;
μ = coefficient of kinetic friction
m = mass of the body
g = acceleration due to gravity = 10m/s²
Equation (i) then becomes;
F = [tex]F_{A}[/tex] - μmg -------------------(ii)
Given from question;
m = mass of motorcycle = 150kg
μ = 0.03
[tex]F_{A}[/tex] = 250N
Substitute these values into equation (ii) as follows;
F = 250 - (0.03 x 150 x 10)
F = 250 - (45)
F = 205N
Therefore, the net force applied to the motorcycle is 205N

Artist's conception of the 6,000-km-plus northward journey of the "India" landmass (Indian Plate) before its collision with Asia (Eurasian Plate).
Explanation:
India has forcefully introduced 40 to 50 million years ago. The landmass of India was once present south of the Equator, but the northern margins began to collide against the Eurasian plate.
Tethys sea was one of the vast oceans, which separated the landmass of India and Asia. Pangaea destruction occurred 200 million years ago, which caused India to forge northward.
Around 80 million years ago, India was approximately 6,400 kilometers south of the Asian continent. The landmass of India when reached the Eurasian plate, it collided because of the same density.
Thus, the plates of Eurasian and Indian landmass collided and caused the forming of hills. The Indian landmass continued to push towards the north, which caused the hills to convert into mountains.

9. Bryce drove his car 10 km from his house to Belle Plaine. It took him 8 minutes. He got stopped at a long
traffic light on the return home and so he took 2 minutes longer on the return trip. What was Bryce's average
speed in km per minute? (3 pt)
Answers
Answer:
2 km/minute
Explanation:
Here, we are asked to calculate the average speed in km/minute.
As we know that,
Average speed = Total distance ÷ Total time taken
Here,
→ Total distance = 10 km + 10 km
Because, he first drove 10 km from his house to Belle Plaine and then he again came back to his house.
→ Total distance = 20 km
→ Total time = 8 minutes + 2 minutes
→ Total time = 10 minutes
Substitute the values in the formula of average speed,
→ Average speed = Total distance ÷ Total time taken
→ Average speed = 20km ÷ 10 minutes
→ Average speed = 2 km per minute

Which speed-time graph represents the motion of a light ball dropped from a
great height near the surface of the Earth and near the surface of the Moon?
Answers
Answer:
Speed-time graph C
Explanation:
The speed of the ball is constant towards surface of Moon since no forces acting.
Speed of ball increases as ball approaches the surface of Earth.
A body's surface gravity is directly proportional to its mass, but inversely related to the square of its radius. Thus, option C is correct.
What is the gravitational field strength on the Earth?
The mass of the Earth's moon is significantly lower than that of the planet. The Moon is not just smaller than Earth, but it is also only around 60% as dense. On the Moon, there is less gravitational field attraction than on Earth, hence a person weighs less there.
The Moon's surface gravity is about 1/6th as powerful as Earth's, or 1.6 meters per second every second. The Moon's surface gravity is lower because it has a smaller mass than Earth.
Due to the absence of forces, the ball is moving toward the surface of the moon at a constant speed.
Therefore, The speed of the ball rises as it gets closer to the Earth's surface.

what would be the final temperature of a mixture of water at 40 degree celsius temperature and 60 grams of water at 80 degree celsius temperature
Answers
Answer:
T = 60°C
Explanation:
We are given;
Mass of water in both cases as 60g.
Thus; m1 = m2 = 60 g
Temperature of first water; T1 = 40°C
Temperature of 2nd water; T2 = 80°C
Let final temperature be T.
To solve for the final temperature, we will use the formula;
(m1 + m2)T = ((m1•T1) + (m2•T2))
(60 + 60)T = ((60 × 40) + (60 × 80))
120T = 7200
T = 7200/120
T = 60°C
