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.

How does an atom of strontium 88 become a strontium ion with a+2 charge ?
Oksana_A [137]

<u>Answer:</u>

Strontium atom loses 2 electrons to become an ion.

<u>Explanation:</u>

Strontium (an Alkaline Earth metal) is the 38th element found in the Group 2 of the periodic table.

A Strontium atom has same number of electrons as its protons. It has a +2 electronegativity because it belongs to group 2 of the periodic table so it has the tendency to lose 2 electrons to form a positive ion.

Therefor, Strontium atom loses 2 electrons to become an ion with 2 electrons lesser than its atom.

A 10.0 V battery is connected across two resistors in series. One resistor has resistance of 840.0 Ω and the other has resistanc
REY [17]

Answer:

Explanation:

There are a couple of ways you could do this.

The easiest is to use E*R1/(R1 + R2)

  • E = 10 volts
  • R1 = 590 ohms
  • R2 = 840 ohms

So the result would be

E_590 = 10 * 590/(590 + 840)

E_590 = 10 * 590/ (1430)

E_590 = 4.13 volts rounded.

You could do this a slightly longer way.

R = 1430 (total ohms in series.

E = 10 volts

I = ???

I = E/R

I = 10 / 1430

I = 0.00699

Now use this current to figure out the voltage drop.

E = I * R

I = 0.00699 amps

R = 590 ohms

E = 0.00699 * 590

E = 4.13 volts

Pick the way of doing it you like best.

Shari uses the data in the table to predict how her weight on Venus would compare with her weight on Earth.
spin [16.1K]

Answer :  <em>Her weight is lower on Venus because the acceleration due to gravity is lower.</em>

Explanation :

Venus is also called as Earth's twin. This is because both the mass and the size of Earth and Venus are almost same. The acceleration due to gravity on earth is 9.8\ m/s^2 while on Venus is 8.87\ m/s^2.

So, when Shari measure her weight on Venus she found her weight is lower on Venus. This is because the acceleration due to gravity is lower on the surface of Venus as compared to the Earth.

Since,    w=mg

i.e. weight depends on g.

<em>So, correct prediction is (b)</em>

A ball, which has a mass of 1.25 kg, is thrown straight up from the top of a building 225 meters tall with a velocity of 52.0 m/
Anastasy [175]

First we will find the speed of the ball just before it will hit the floor

so in order to find the speed of the cart we will first use energy conservation

KE_i + PE_i = KE_f + PE_f

\frac{1}{2}mv_i^2 + mgh = \frac{1}{2}mv_f^2 + 0

\frac{1}{2}(1.25)(52)^2 + 1.25(9.8)(225) = \frac{1}{2}(1.25)v_f^2

So by solving above equation we will have

v_f = 84.3 m/s

now in order to find the momentum we can use

P = mv

P = 1.25 \times 84.3

P = 105.4 kg m/s
