Jackie rides her bike to school every day and enjoys playing beach volleyball on weekends. She also helps with tasks around the house, like pulling weeds in the garden and sweeping the porch. Which of the following describes a possible benefit of Jackie's physical activity? (1 point) a Jackie may be less likely to commit to a healthy future. b Jackie may have an increased chance of disease. c Jackie may maintain healthy body fat levels. d Jackie may require more assistance performing daily tasks.
Answer:
The correct answer is - C) Jackie may maintain healthy body fat levels.
Explanation:
Jackie has a very active daily and on weekends routine that includes riding the bike, playing volleyball, pushing weeds, and sweeping the porch. The activities that Jackie is performing daily as well as the time that she spends on exercise may help her to maintain body fat levels.
Being physically active helps in maintaining fat levels in the body of an individual, and it is healthy for the individual.
Thus, the correct answer is - C) Jackie may maintain healthy body fat levels.

Harish runs on a straight path with the velocity of 16 m/s . How long distance will he cover in 2 minutes ?
Answer:
Harish went 1.92 Km in 2 minutes.
Explanation:
Harish is running at 16 m/s (Meters per second) and we need to find how far he goes in 2 minutes.
We can use this formula to calulate the distance:
m/s x time
We know that Harish is going 16m/s so let's plug that in:
16 (m/s) x time
We also should know that 2 minutes is 120 seconds - Let's plug that in too:
16 (m/s) x 120 (Seconds)
Now we calculate:
16 x 120 = 1920
Harish went 1,920 meters in 2 minutes.
Even though we have a correct answer, we can still make it easier to read by converting meters into kilometers.
1 Kilometer (Km) is equal to 1,000 meters.
All we need to do now is divide 1,920 by 1,000 and that will gove us our simplified answer of:
1.92 Km
Answer:
1.92 km
Explanation:
I will explain you:
2×60=120
we have to take 16×120=1920km bro

Explanation:
Write a scientific explanation about weather or not a single cell constitutes a system. (CER)
Answer:
Weather such as raining has water molecules/droplets thats been evaporated from the ocean and other areas that's wet, the water will connect and soon the mass of the water will become heavy causing rainfall. Snow in another case has been caused to freeze from low climates creating a snow flake to fall from the sky. Hail is another case however the water that becomes ice is far more larger.
The variety of activities that take place daily in our atmosphere makes up for the weather.
What is the weather like?The weather varies across the globe and changes over a few minutes, hours, days, and weeks. The troposphere, the region of Earth's atmosphere closest to the surface, is where most weather occurs.
Changes in air pressure determine the weather that occurs in a given place. The weight of the enormous quantities of air molecules that make up the atmosphere is what causes air pressure.
Usually, clear, blue skies are seen when air pressure is high. The high pressure prevents clouds from developing by causing air to flow down and fan out as it gets close to the ground.
Low air pressure causes air to move together before converging upward, where it rises, cools, and forms clouds.

Q7) A box sliding with a velocity of 5 m/s accelerates at 2 m/s^2. How
much is the box displacement after 6 s?
Answer:
The box displacement after 6 seconds is 66 meters.
Explanation:
Let suppose that velocity given in statement represents the initial velocity of the box and, likewise, the box accelerates at constant rate. Then, the displacement of the object ([tex]\Delta s[/tex]), in meters, can be determined by the following expression:
[tex]\Delta s = v_{o}\cdot t+\frac{1}{2}\cdot a\cdot t^{2}[/tex] (1)
Where:
[tex]v_{o}[/tex] - Initial velocity, in meters per second.
[tex]t[/tex] - Time, in seconds.
[tex]a[/tex] - Acceleration, in meters per square second.
If we know that [tex]v_{o} = 5\,\frac{m}{s}[/tex], [tex]t = 6\,s[/tex] and [tex]a = 2\,\frac{m}{s^{2}}[/tex], then the box displacement after 6 seconds is:
[tex]\Delta s = 66\,m[/tex]
The box displacement after 6 seconds is 66 meters.

Answer: The balloons repel each other but attract the rabbit fur.
Brainliest pwease if I could do you any help!
˙ᵕ˙Here, both the balloons gains a negative charge through rubbing and they attracts to the neutral rabbit fur. But the balloons themselves repel each other. Hence, option B is correct.
What is static electricity ?When a material rub on a surface its electrons gets aligned and acquire a negative charge. This negative charge when comes in contact with a neutral material, the second one get partially polarized and gets attracted to the negative charge.
This flow of electrons through induced polarization is called static electricity. When the balloon are rubbed with the neutral rabbit fur and gets negatively charged by friction.
This negatively charged balloons repel each other but they induce a polarity to the neutral rabbit fur and its positive charges gets aligned with the negative charges results in electrostatic attraction.

Cual es la rapidez media de un guepardo que recorre 100 metros en 4 segundos? ¿Y si recorre 50 m en 2 s?
Answer:
La rapidez media es 25 m/s en ambos casos.
Explanation:
Podemos definir como rapidez media al cociente entre la distancia total recorrida y el tiempo que se tardó en recorrer dicha distancia.
Así tenemos:
Rapidez media = Distancia/tiempo.
Entonces si el guepardo recorre 100m en 4 segundos, su rapidez media es:
Rapidez media = 100m/4s = 25 m/s
En el caso de que el guepardo recorre 50 metros en 2 segundos, su rapidez media será:
rapidez media = 50m/2s = 25m/s
Es el mismo resultado, pues recorrió la mitad de distancia en la mitad de tiempo.

Three charges are on a line. A positive charge is on the far left labeled q Subscript 1 baseline positive 6 Coulombs. The second charge is 2 m away and is labeled q Subscript 2 baseline negative 4 Coulombs. The third charge is 1 m away and is labeled q Subscript 3 baseline = positive 3 Coulombs.
What is the electrical force between q2 and q3?
Recall that k = 8.99 × 109 N•meters squared over Coulombs squared..
1.0 × 1011 N
–1.1 × 1011 N
–1.6 × 1011 N
1.8 × 1011 N
Answer:
B) –1.1 × 1011 N
Explanation:
Since the second charge is 2 m away and is labeled q₂ = - 4 Coulombs. The third charge is 1 m away and is labeled q₃ = + 3 Coulombs, the electrical force between q₂ and q₃ is -1.1 × 10¹¹ N
To answer the question, we need to find the electrical force of attraction between two charges and this is given by Coulomb's law
Coulomb's lawThis states that the electrical force of attraction between two charges, F is directly proportional to the product of the charges q and Q and inversely proportional to the square of their distance apart, d.
So, mathematically F = kqQ/d²
Now, given that there are three charges are on a line. A positive charge is on the far left labeled q₁ = + 6 Coulombs. The second charge is 2 m away and is labeled q₂ = - 4 Coulombs. The third charge is 1 m away and is labeled q₃ = + 3 Coulombs.
The electrical force of attraction between q₂ and q₃So, the electrical force of attraction between q₂ and q₃ is F = kq₂q₃/d² where
k = 8.99 × 10⁹ Nm²/C², q₂ = - 4 C, q₃ = + 3 C and d = 1 m (since q₂ and q₃ are 1 m apart)Substituting the values of the variables into the equation, we have
F = kq₂q₃/d²
F = 8.99 × 10⁹ Nm²/C² × (-4 C) × (+ 3 C)/(1 m)²
F = 8.99 × 10⁹ Nm²/C² × (-12 C²)/(1 m)²
F = -107.88 × 10⁹ Nm²/1 m²
F = -1.0788 × 10¹¹ N
F ≅ -1.1 × 10¹¹ N
Since the second charge is 2 m away and is labeled q₂ = - 4 Coulombs. The third charge is 1 m away and is labeled q₃ = + 3 Coulombs, the electrical force between q₂ and q₃ is -1.1 × 10¹¹ N

I walked my dog 100 meters North to the end of the block, and 50 meters East to the park. After the park, I walked 60 meters South to my friend's house. What is the total distance traveled? Is the displacement of my journey scalar or vector?
Answer:
The answer is below
Explanation:
Distance is a measurement of how far apart two points are. Distance is a scalar quantity, i.e. it has magnitude and no direction.
Total distance traveled = distance traveled north + distance traveled east + distance traveled south
Total distance traveled = 100 + 50 + 60 = 210 meters
Displacement is the shortest distance between the starting and end points.
displacement² = 50² + (100 - 60)²
displacement² = 2500 + 1600
displacement = 64 meters
The displacement of the journey is vector, because displacement is a vector quantity.
