Answer: A. Overweight and obesity
Explanation:
Overweight and obesity are labeled for ranges of weight that are greater than what is generally considered healthy for a given height. Hence, option A is correct.
What are Overweight and obesity?Overweight and obesity are calculated by Body Mass Index (BMI). BMI is a person's weight in kilograms divided by the square of height in meters. The healthy adult human BMI ranges from 18.5 to 25.
If BMI is less than 18.5, it falls within the underweight range. If the BMI ranges from 25.0 to 29.9, it falls within the overweight range. If the BMI is greater than 30, it comes under the obesity range. A high BMI indicates high fatness.
Obesity and overweight are determined as an abnormal growth or excessive fat accumulation in the healthy range. It is caused by an energy imbalance between calories consumed and calories expended.
Obesity and Being overweight can cause certain diseases and health issues. It increases the risk of high blood pressure, heart disease, diabetes, and stroke.
It is important to maintain a healthy range BMI. Obesity and overweight are reduced by making the choice of healthier foods and regular physical activities like yoga and exercise.

A baseball player throws a baseball at 42 m/s. If the other player catching the baseball is 18 m from the player, how much time does it take the baseball to reach him?
Divide the distance by the speed:
(18 m) / (42 m/s) = 3/7 s ≈ 0.43 s
A farmer is attempting to take a chicken across a river in a motorboat while a fox waits on shore with a bag of grain. If the river has a current with a velocity of 2.0 m/s and the boat maintains a speed relative to the water of 4.5 m/s, in which direction (angle) should the farmer point the boat so that the boat follows a straight path directly across the river?
Answer:
The farmer should go approximately 26.39° relative to the direction of and toward the river current velocity or approximate 90 - 26.39 which is 63.12° clockwise from the perpendicular direction across the river
Explanation:
The given parameters are;
The river current velocity = 2.0 m/s
The boat speed relative to the water = 4.5 m/s
Therefore, for the boat to have a resultant velocity that will follow a straight path directly across the river, we have;
The water current velocity, 2 m/s, the relative speed of the boat, 4.5 m/s, and the resultant velocity, v, form a right triangle, with the water current being the base, and the boat's relative speed being the hypotenuse side, while the height is the resultant velocity
Therefore, we have;
The direction of the boat relative to the direction of current the river = θ
The relative speed of the boat × sin(θ°) = The river current velocity
∴ sin(θ°) = The river current velocity/(The relative speed of the boat)
Which gives;
sin(θ°) = 2 m/s/(4.5 m/s) = 2/4.5 = 4/9
θ = sin⁻¹ = sin⁻¹(4/9) ≈ 26.39°
Therefore, the farmer should go approximately 26.39° relative to the direction of and toward the river current velocity or approximate 90 - 26.39 which is 63.12° clockwise from the perpendicular direction across the river.

Where does the energy of plasma come from?
Answer:
El plasma es un estado de la materia que se caracteriza por su alta energía e inestabilidad. La energía del plasma, entrando en contacto con la superficie de materiales sólidos – plásticos o metales – modifica sus propiedades fundamentales, como por ejemplo la tensión superficial.
Explanation:
Plasma – el cuarto estado de la materia
A través de aportación de energía se cambia el estado de la materia: de sólido a líquido y de líquido a gaseoso. Si al gas se aporta energía adicional, éste se ioniza, es decir, que por la mayor energía el gas se convierte en plasma - el así llamado “cuarto estado de la materia”.

HELP. A river flows South with a speed of 8m/s. From the shore, you see a boat moving South with a speed of 10 m/s. From their frame of reference, how fast are the rowers moving?
Answer:
18 m/s
Explanation:
Given that,
Speed of river is 8 m/s due South
From the shore, you see a boat moving South with a speed of 10 m/s. Both boat and river are moving in same direction. The resultant velocity will add up.
v = 10 m/s + 8 m/s
v = 18 m/s
Hence, the rowers are moving with a speed of 18 m/s.

Ravi, Rajiv and Shyam are sitting inside a room. The body temperature of. Ravi, Rajiv and Shyam are 35.8 ℃, 36.2 ℃ and 36.4 ℃. It is given that the temperature of air present in the room is 36.1 ℃. Who among them will feel cold? Give Reason, please reply as soon as possible!! (explanation needed).
Answer:
"Cold" in this case, is defined as a difference between the body temperature and the room/ambient temperature.
If the body temperature is higher than the room temperature, then the "sensors" in our skin will sense that the ambient temperature is lower than ours, then we feel "cold"
The room temperature is: 36.1°C.
The higher body temperature is the one of Shyam, 36.4°C
The difference is really small:
36.4°C - 36.1°C = 0.3°C

An object is released from rest near a planet's surface. A graph of the acceleration as a
function of time for the object is shown for the 4s after the object is released. The
positive direction is considered to be upward. What is the displacement of the object after 2s?
Answer:
The displacement and direction of the body after 2 seconds is 10 meters downwards
Explanation:
The given information are;
From the graph, the acceleration, is seen as the horizontal line that starts from the y-coordinate, y = -5 m/s²
Therefore;
The acceleration of the body after it was released from rest = -5 m/s² with an upward direction;
Which gives, the acceleration of the body downwards = Opposite sign to the acceleration of the body upwards = 5 m/s²
The displacement, s, of the body after 2 seconds is given by the following equation of motion;
s = u·t + 1/2·a·t²
Where;
u = The initial velocity of the body = 0 m/s
t = The time duration of the displacement = 2 s
a = The acceleration of the body = 5 m/s², downwards
Therefore, by substituting the values, we have;
s = 0 × 2 + 1/2 × 5 × 2² = 10 meters
s = 10 meters
The displacement of the body after 2 seconds = 10 meters
Given that the direction of the displacement and the direction of the acceleration are the same, we have;
The displacement and direction of the body after 2 seconds = 10 meters downwards.
The displacement of the object moving downwards is 10 m.
The given parameters;
time of motion of the object, t = 2 sacceleration of the object constant = -5 m/s²The displacement of the object moving downwards (negative direction) is calculated using the second kinematic equation as shown below;
s = ut - ¹/₂at²
s = 0 - 0.5 x (-5) x (2)²
s = 10 m
Thus, the displacement of the object moving downwards is 10 m.

An airplane flies 33 m/s due east while experiencing a tailwind
of unknown velocity due north. The resultant velocity is
determined to be 35.11 m/s northeast. What is the velocity of
the northern tailwind?
Explanation:
Use Pythagorean theorem.
v² = vₓ² + vᵧ²
(35.11 m/s)² = (33 m/s)² + vᵧ²
vᵧ = 12 m/s
The velocity of the northern tailwind is 12 m/s.
To find the velocity of northern tailwind, the given values are,
Resultant velocity v = 35.11 m/s,
Velocity of plane vₓ = 33 m/s.
What is the resultant velocity?The resultant velocity of the plane is the sum of the velocities of the plane and the wind with the consideration of their directions. The sum of the vector forces on an object is equal to the scalar product of the object's mass and its acceleration vector.The plane heads east and the wind being a tailwind also heads north east. Hence, we add their values using Pythagorean theorem,Use Pythagorean theorem.
v² = vₓ² + vᵧ²
(35.11 m/s)² = (33 m/s)² + vᵧ²
vᵧ² = 35.11² - 33²
vᵧ² = 1232.71 - 1089
vᵧ = √143.71
vᵧ = 11.98 m/s
which can be vᵧ = 12 m/s
Hence, the velocity of the northern tailwind is vᵧ = 12 m/s.

A giraffe, standing 6.00 m tall, bites a branch off a tree to chew on the leaves
and lets the branch fall to the ground. How long does it take the branch to hit
the ground?
Answer:
1.11 s.
Explanation:
From the question given above, the following data were obtained:
Height (H) = 6 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =.?
The time taken for the branch to hit the ground can be obtained as follow:
H = ½gt²
6 = ½ × 9.8 × t²
6 = 4.9 × t²
Divide both side by 4.9
t² = 6/4.9
Take the square root of both side
t = √(6/4.9)
t = 1.11 s
Therefore, it will take 1.11 s for the branch to hit the ground.
A cricket batsman hits a ball at a speed of 27m/s at an angle of 60 degrees to the horizontal. How far away would you have to stand in order to catch it (assuming you want to catch it just before it hits the ground)?
Answer:
64.4 m
Explanation:
First, find how long it takes to land. Given in the y direction:
Δy = 0 m
v₀ = 27 m/s sin 60° ≈ 23.4 m/s
a = -9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
0 m = (23.4 m/s) t + ½ (-9.8 m/s²) t²
t = 4.77 s
Next, find how far it travels in that time. Given in the x direction:
v₀ = 27 m/s cos 60° = 13.5 m/s
a = 0 m/s²
t = 4.77 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (13.5 m/s) (4.77 s) + ½ (0 m/s²) (4.77 s)²
Δx = 64.4 m
