¿Qué pasa en nuestro cerebro cuando tomamos decisiones? Ejemplo: Estoy tocando una plancha caliente, y saco la mano rápidamente, ¿que paso en mi cerebro?
Answer:
Debido a la información de las neuronas sensoriales al cerebro.
Explicación:
Cuando toco una plancha caliente, extiendo la mano rápidamente porque las neuronas sensoriales presentes en la piel de nuestro cuerpo envían señales al sistema nervioso central, es decir, al cerebro. El cerebro toma decisiones de acuerdo con los estímulos y envía instrucciones a través de las neuronas motoras a los músculos para retirar las manos del hierro caliente a fin de evitar efectos nocivos en la piel debido al calor. El lóbulo frontal es una parte del cerebro que controla la personalidad, la toma de decisiones y el razonamiento.

A body is moving with a velocity of 15m/s . If the motion is uniform. How much distance will be the velocity after 10s
Answer:
Distance = 150 meters.
Explanation:
Given the following data;
Velocity = 15 m/s
Time = 10 seconds
To find the distance;
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
[tex]Velocity = \frac{distance}{time}[/tex]
Making distance the subject of formula, we have;
[tex] Distance = velocity * time [/tex]
[tex] Distance = 15 * 10 [/tex]
Distance = 150 meters

If it takes 726 watts of power to move an object 36 m in 14 s, what is the mass of the object?
Answer:
Explanation:
Given
Power (p)= 726 watt
Time (t) = 14 sec
distance travelled (d; h) = 36 m
mass (m) = ?
we know
Power (p) = W/t ( w = work done )
p = m * g * h / t ( w = m * g* h)
726 = m * 10 * 36 / 14 ( g = 10 m/s^2)
m = 28. 23 kg
or if we use the value of g as 9.8 m/s^2
the mass will be
= 28.8 kg
hope it helps :)
The mass of the object if it takes 726 watts of power to move an object 36 m in 14 s is 28.8 kg.
What is mass?An object's inertia, a fundamental property, is measured by its mass, a fundamental indicator of the volume of substance inside the thing. Definitions of mass can seem circular since it is such a fundamental quantity and is challenging to define in terms of another.
It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.
Given:
The Power, p = 726 watt
The Time, t = 14 sec
distance travelled, d = 36 m
Calculate the power by the given formula
p = W / t
p = m * g * h / t ( w = m * g* h)
726 = m * 9.8 * 36 / 14 ( g = 10 m/s^2)
m = 28. 8 kg
Therefore, the mass of the object If it takes 726 watts of power to move an object 36 m in 14 s is 28.8 kg.

describe how you would determine the half-life of a substance from an activity/time graph, plsplspls help
Answer: At any time, the number of decays per reasonable
time unit is proportional to the amount of the isotope present. (This is expressed by the first-order rate equation for a one-decay process.) Therefore, it does not matter whether one looks at the amount or the number of decays. It may be easier to measure the number of decays by e.g. a Geiger counter and prefer it for that reason.
It now matters what you understand to be the rate: the number of decays per second or the percentage of nuclei decaying at any given time. The first becomes less over time, the second one is a constant for each isotope.
You must have a reasonable number of decays within your time unit. If the half-life is long, it makes little sense to look at millisecond slices.

A high-temperature gas is compared to the same gas at lower temperature. Which of the following statements is true?
A. Every molecule in the high-temperature gas is moving faster than every molecule in the low-temperature gas.
B. The average molecular speed in the high-temperature gas is faster than the average molecular speed in the low-
temperature gas.
C. Both A and B are true.
D. Neither A nor B is true.
Answer:
I think it is C
Explanation:
If the temperature of a gas increases, the gas particles have a higher average speed as they gain kinetic energy. They collide more frequently with the walls of the container, which produces a bigger pressure.

According to Newton’s second law, the mass of an object is 120kg and it is accelerating at a rate of 5m/s2 . The object’s force would be
Answer:
F = 600 N
Explanation:
The second law is F = m * a
The mass (m) is in kg = 120
The acceleration in in m/s^2 = 5
The force is in Newtons.
m and a do not require any conversions. They are in the correct units.
F = 120 * 5
F = 600 N

iii. 1 minute
Answer:
a] 3000hz
b]3.33 × 10⁻⁴
ci]300
ii] 3000
iii]60,000
Explanation:
If a wave is travelling at 3000 m/s and has a wavelength of 1 meter the frequency of the wave would be 3000 Hz and the time period of the wave would be 3.33×10⁻⁴ seconds.
What is the frequency?It can be defined as the number of cycles completed per second. It is represented in hertz and inversely proportional to the wavelength.
Frequency = 1/T
As given in the problem If a wave is travelling at 3000 m/s and has a wavelength of 1 meter,
The frequency of the wave would be 3000 Hz.
The time period of the wave would be 3.33×10⁻⁴ seconds.
There would be 3000 complete wave cycles in 1 second, 300 wave cycles in 10 seconds, and 50 wave cycles in 1 minute.

A pump is to lift 20.0 kg of water per minute through a height of 25.50 m. What output rating should the pump motor have?
Answer:
the output rating that should the pump motor have is 83.30 Watt
Explanation:
Given that
The pump lift 20 kg of water per minute having a height of 25.50 m
We need to find out the output rating that should the pump motor have
As we know that
power = energy ÷ time
= m g h ÷ t
= 20.0 × 9.8 × 25.50 ÷ 60
= 83.30 Watts
Hence, the output rating that should the pump motor have is 83.30 Watt
