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”.

Texting and driving is a dangerous act
and is illegal in many areas. Suppose a driver takes 3.5 seconds to send a text. Travelling at 95 km/h, how far in meters did the vehicle travel while the driver was distracted? (Hint: How many seconds are in an hour?
How many meters are in a km?)
Answer:
s = 92.36 m
Explanation:
The distance covered by an object moving with uniform speed is given by the following formula:
s = vt
where,
s = distance covered by car during the time when driver was distracted in texting = ?
v = uniform speed of car = (95 km/h)(1 h/3600 s)(1000 m/1 km) = 26.39 m/s
t = time taken by the driver for texting = 3.5 s
Therefore, using these values in equation, we get:
s = (26.39 m/s)(3.5 s)
s = 92.36 m

If the acceleration of a motorboat is 4.0 m/s2, and the motorboat starts from rest, what is its velocity after 6.0 s?
Answer:
The velocity of the motorboat after 6s is 24 m/s.
Explanation:
Given;
acceleration of the motorboat, a = 4.0 m/s²
initial velocity of the motorboat, u = 0
time of motion of the motorboat = 6s
Apply the following kinematic equation to determine the velocity of the motorboat after 6 ;
v = u + at
v = 0 + (4 x 6)
v = 24 m/s
Therefore, the velocity of the motorboat after 6s is 24 m/s.

A satellite in space has a mass of 252 kg. The engines on it provide a net force of 6.81×10-3 N. How long will it take for this satellite to go from rest to a final velocity of 262 m/s forward?
Acceleration = (force) / (mass)
Acceleration = (6.81 x 10⁻³ N) / (252 kg)
Acceleration = 2.70 x 10⁻⁵ m/s²
Time = (change in v) / (acceleration)
Time = (262 m/s) / (2.70 x 10⁻⁵ m/s²)
Time = 9,703,704 seconds
That's 2,695.5 hours , or 112.3 mean solar Earth days .

A person is walking from the front of a train toward the back of a train at a constant velocity of 3 mph. The train is moving forward at a velocity of 20 mph. What is the velocity of the walking person relative to the land outside the train?
Explanation:
This is the Galilean transformation.
V' = V - U where want to find V' in the primed frame of reference.
The primed frame is moving at speed U = -20 relative to the train.
V = -3 is the speed of the person in the frame of the train.
Then V' = -3 - (-20) = 17 mph relative to the land outside the train.
The friction of the water on a boat produces an acceleration of -10 m/s2. If the
boat is traveling at 30 m/s and the motor is shut off, how long does it take the boat
to slow down to 5.0 m/s?
a
2.5 s
b 2.35
c
2.2 s
d
2.0 s
Answer:2.5s
Explanation:
Idk I guessed and got it right
Friction is the force that exists between two surfaces that are sliding or attempting to slide across each other.
The acceleration produced by the friction of water is a = [tex]-10 m/s^2[/tex]
The boat takes 2.5 seconds to slow down.
What causes of friction?Surface roughness: When two rough surfaces collide, they generate frictional force or an opposing force, which can sometimes be converted into heat. Body deformation: Deformations in the body or the surface of the body in contact may cause friction during motion.Friction is the force that exists between two surfaces that are sliding or attempting to slide across each other. For example, friction makes it difficult to push a book across the floor. Friction always acts in the opposite direction that the object is moving or attempting to move.The equation that rules the change of velocities is:
[tex]V = V _0 + at[/tex]
Where:
a = acceleration
Vo = initial speed
v = final speed
t = time
The acceleration produced by the friction of water is a = [tex]-10 m/s^2[/tex] and the boat is initially traveling at v=30 m/s. When the motor is shut off, the boat will start braking until it stops. We need to find the time it takes to ready the final speed of v=5 m/s.
t = [tex]\frac{V - V_0 }{a}[/tex] = -5-30 /10 = 2.5 s.
The boat takes 2.5 seconds to slow down.

Eric has a mass of 19.0 kg on the earth. What is Eric's weight on earth? What is Eric's weight on Mars? where the acceleration of gravity is approximately 0.381 of that of Earth's? ________.
Answer:
Weight on Earth = We = 186.2 N
Weight on Mars = Wm = 70.94 N
Explanation:
The weight of an object is defined as the force applied on the object by the gravitational field. The magnitude of weight is given by the following formula:
W = mg
were,
W= Weight of Eric
m = mass of Eric
g = acceleration due to gravity
ON EARTH:
W = We = Eric's Weight on Earth = ?
m = Eric's Mass on Earth = 19 kg
ge = acceleration due to gravity on Earth = 9.8 m/s²
Therefore,
We = (19 kg)(9.8 m/s²)
We = 186.2 N
ON MARS:
W = Wm = Eric's Weight on Mars = ?
m = Eric's Mass on Mars = 19 kg
gm = acceleration due to gravity on Mars = 0.381(ge) = (0.381)9.8 m/s² = 3.733 m/s²
Therefore,
Wm = (19 kg)(3.733 m/s²)
Wm = 70.94 N

What are significant figures?In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.
If a number describing the result of a measurement (such as length, pressure, volume, or mass) includes more digits than the number of digits permitted by the measurement resolution, only the digits allowed by the measurement resolution can be significant figures.
As given in the problem we have to convert 3 x 10⁻⁹ s into milliseconds
1 second = 1×10³ milliseconds
3 x 10⁻⁹ seconds = (3 x 10⁻⁹) × (1×10³ )
= 3 x 10⁻⁶milliseconds
Thus, 3 x 10⁻⁹ s converted into milliseconds it would be 3 x 10⁻⁶ milliseconds

During a sunny afternoon, the sun suddenly seems much less bright than usual. The daylight seems much less intense, as if there is a dense cloud cover, but there’s no clouds in the sky. After about half an hour, everything seems normal again. Which claim about the temporary decrease in light can be supported by the evidence?
Answer:
D). A sudden change in temperature increased the density of the atmosphere.
Explanation:
The claim that can be made and supported with evidence regarding the temporary decrease in light would be 'a sudden change in temperature will increase the density of the atmosphere.' As the temperature increases, the molecules in the atmosphere begin to move fastly which causes a decrease in atmosphere density while it increases with the fall in temperature. As a result, the intensity of sunlight gets affected due to molecules being heavier and floating in the atmosphere. Thus, option D is the correct answer.
Answer: Its the atmosphere
