When celery is placed in a glass of pure water the solution inside its cells is _____ compared to the water.?

Answers

Answer 1

Answer: The correct answer to the question above is hypertonic. When celery is being placed in a glass of pure water, the solution inside its cells is going to appear as hypertonic compared to the water. This means that the cells inside has a higher concentration than outside.

A periodic wave is produced by a vibratingtuning fork. The amplitude of the wave would be
greater if the tuning fork were
(1) struck more softly
(2) struck harder
(3) replaced by a lower frequency tuning fork
(4) replaced by a higher frequency tuning fork

Answers

The amplitude of the wave would be greater if the tuning fork were "struck harder" since this would make for a louder noise, which happens from higher amplitudes.

The mc002-1.jpgHrxn of formation of carbon dioxide is negative. Which statement is true?

Answers

When the formation of carbon dioxide is negative, it means that it releases heat to the surroundings. When it releases heat to the surroundings, the reaction is exothermic.

Adam applies an input force to the pulley as he pulls down to lift the object. As he does this, Adam wonders about how the pulley is helping him. How is the pulley helping Adam lift the object?a. All of these answers are correct.
b. A fixed pulley lowers the amount of force needed to do the same amount of work.
c. A fixed pulley increases the distance over which the force is applied.
d. A fixed pulley helps Adam change the direction of the effort force.

Answers

Explanation :

Adam applies an input force to the pulley as he pulls down to lift the object. As he does this, Adam wonders about how the pulley is helping him.

A pulley is a simple machine which always changes the direction of effort forces. It consists of a rope and a wheel.

The pulley can be of three types i.e. a fixed pulley, movable pulleys and combined-pulley systems.

Hence, the correct option is (d) " A fixed pulley helps Adam change the direction of the effort force ".

A fixed pulley changes the direction of the effort force, but not its magnitude.

An electron is released from rest at the negative plate of a parallel plate capacitor. The charge per unit area on each plate is = 2.5 x 10⁻⁷ C/m², and the plates are separated by a distance of 1.7 x 10⁻² m. How fast is the electron moving just before it reaches the positive plate?

Answers

The speed of the electron before reaching the positive plate is $1.30 * 10^(7)\ m / s$

Explanation:

As per Gauss law of electro statistics, the electric field generated by a capacitor is directly proportional to the surface charge density of the plate and inversely proportional to the dielectric constant. In simple words, the electric field is proportional to the surface charge density. So,

$\text {Electric field}=(\sigma)/(\varepsilon_(0))$

And then from the second law of motion, $F=m * acceleration$

So acceleration exerted by the electrons will be directly proportional to the force exerted on them and inversely proportional to the mass of the electron.

$Acceleration =(F)/(m)$

Since force is also calculated as product of charge with electric field in electrostatic force,

$\text {Acceleration}=(q E)/(m)=(q \sigma)/(m \varepsilon_(0))$

So, the charge of electron $q=1.6 * 10^(-19)\ \mathrm{C}, \sigma=\text { Charge per unit area }=2.5 * 10^(-7)\ \mathrm{C} / \mathrm{m}^(2)$

m is the mass of electron which is equal to $9.11 * 10^(-31)\ \mathrm{kg}$

$\varepsilon_(0)=8.85 * 10^(-12)\ \mathrm{Nm}^(2) \mathrm{C}^(-2)$

Then,

$\text { Acceleration }=(1.6 * 2.5 * 10^(-19) * 10^(-7))/(9.11 * 8.85 * 10^(-31) * 10^(-12))=(4 * 10^(-19-7))/(80.62 * 10^(-31-12))$

$\text { Acceleration }=0.0496 * 10^(-19-7+31+12)=0.0496 * 10^(17)\ \mathrm{m} / \mathrm{s}^(2)$

So the acceleration of the electron in the capacitor will be $4.96 * 10^(15) m / s^(2)$

Then, the velocity can be observed from the third equation of motion.

$v^(2)=u^(2)+2 a s$

As u = 0 and s is the distance of separation between two plates.

$\begin{array}{c}v^(2)=0+\left(2 * 4.96 * 10^(15) * 1.7 * 10^(-2)\right) \nv^(2)=16.864 * 10^(15-2)=16.864 * 10^(13)=1.684 * 10^(14)\end{array}$

Thus, $v=\sqrt{\left(1.68 * 10^(14)\right)}=1.30 * 10^(7)\ m/s$

So, the speed of the electron before reaching the positive plate is $1.30 * 10^(7) \mathrm{m} / \mathrm{s}$ .
