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”.

Plasma is a state of matter that is characterized by high energy and instability. The energy of the plasma, coming into contact with the surface of solid materials - plastics or metals - modifies their fundamental properties, such as surface tension.
Explanation:
Plasma - the fourth state of matter
Through the contribution of energy, the state of matter is changed: from solid to liquid and from liquid to gas. If additional energy is supplied to the gas, it is ionized, that is, due to the increased energy the gas is converted into plasma - the so-called “fourth state of matter”.
What force is needed to accelerate a 90 kg punching bag 13 m/s2?
Answer:
The answer is 1170 Newton
Explanation:
Force =. Mass × Acceleration
= 90 × 13
= 1170 Newton
What is uniform acceleration
Answer:
It means zero acceleration.
Explanation:
When a body moves with constant velocity then it is said to be there is no rate of change of velocity takes place because it is constant. So the acceleration becomes zero or uniform acceleration.
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.

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.

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
But still, he will feel the room a little cold for him
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.
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.
