C. flask, Bunsen burner

D. graduated cylinder, balance

Answer:

D. graduated cylinder, balance

Explanation:

In this scenario, A student has been assigned to measure the density of an irregularly shaped piece of metal.

The apparatus which would be most appropriate to carry out this task is a graduated cylinder and balance.

A graduated cylinder can be defined as a measuring cylinder used for the measurement of the volume of an irregularly shaped piece of metal or liquids. It is typically marked with horizontal lines on its side as units of measurement for volume. The balance is then used to weigh the metals mass.

Answer:

The pressure of liquid column is given by p=hpg, where h is depth, p is density and g is acceleration due to gravity.

Therefore, pressure of the liquid column increases with depth. The height of the blood column in a human body is more at feet than at the brain. Therefore, the blood pressure in humans is greater at the feet than the brain.

Explanation:

In terms of attitude change, the fundamental tenet of the cognitive theory would be that individuals are typically driven to lessen dissonance, which could be accomplished by altering their attitudes but also beliefs.

Cognitive theories concentrate on the premise that how exactly what people think causes the arousal of emotions, suggesting that some thoughts, as well as beliefs, as well as beliefs, contribute to healthy emotions as well as adaptive behavior while others lead to disturbing emotions and behaviors.

When people sense unease or guilt as a result of cognitive dissonance, they can actively lessen the dissonance by altering their attitude, beliefs, and even conduct in relation to it in order to attain consistency with both the contradictory cognitions.

g = 9.81 m/s²

Find:

Total time taken t

Computation:

v = u + gt

Answer:

F = 3.105 10⁻²⁰ N

Explanation:

For this exercise let's use Coulomb's law

          F = k q₁ q₂ / r²

in this case each of the grains has a charge

         q1 = 6.0 10⁻¹⁰ C

         q2 = 2.3 10⁻¹⁵ C

and they are separated by a distance r = 2 cm = 0.02 m

let's substitute

          F = 9 10⁹ 6.0 10⁻¹⁰ 2.3 10⁻¹⁵ / 0.02²

         F = 3.105 10⁻²⁰ N

Answer:

Explanation:

speed = distance / time

           = 15m / 3sec

           = 5 m/sec

Answer:

5 m/s

Explanation:

The equation for speed is distance/time. The distance, 15, will go over the time, 3. So, we have 15/3.

You can simplify this by dividing both sides by 3. 15/3 is 5. 3/3 is 1. Now we have 5/1, with 5 as meters, 1 and second.

Therefore, the correct answer is 5 m/s.

Answer:

The correct option is D

Explanation:

Generally, thermal and electrical conductivity is affected by valence electrons in an atom. These valence electrons carry electric charges (or conduct heat as the case may be) throughout the atom. The fewer the valence electrons, the higher its conductivity - this is as a result of free movement within the atom. The higher the valence electrons, the lesser its conductivity and when the outermost electrons have completely filled the outermost shell, the atom would be an insulator as there won't be carriers of electric charges.

Hence, from the above, sodium would be expected to have the highest electrical and  thermal conductivity because it has just one electron in it's outermost shell

Answer:

D. the Earth

Explanation:

The Earth has a solid metal core at the center, which is similar to the pit of a peach. The Earth also has many thick layers of rock and liquid metal between the surface and the center of the Earth, similar to how a peach has a layer of skin and a thick section of fruit. The other answer choices don't have any similarities to a peach. The ocean is entirely liquid, the sun is a ball of gas, and the solar system contains lots of different planets and stars that all are made up of very different things.

division means their melting and boiling point is divided into 180 equal intervals that means each division indicates 1 degree F.

First of all, how long does it take it to fall 0.93m to the floor ?

Distance falling from rest = (1/2) · (g) · (T²)   <== memorize this formula

(0.93 m) = (1/2) (9.8m/s²) (T²)

Divide each side by (4.9 m/s²) :  T² = (0.93/4.9)  =  0.1898 s²

Square root each side:  T to hit the floor = 0.436 second

It got 0.56m away from the desk horizontally in 0.436 sec.

Speed = (distance) / (time)    <=== memorize this formula

Speed = (0.56 m) / (0.436 sec)

Speed = 1.28 m/s

Answer:

t = 3.8 [s]

Explanation:

To solve this problem we must use the following equation of kinematics.

[tex]v_{f} =v_{o} -a*t[/tex]

where:

Vf = final velocity = 5 [m/s]

Vo = initial velocity = 13 [m/s]

a = desacceleration = 2.1 [m/s²]

t = time [s]

As we can see in the above equation the acceleration is negative because the car slows down its velocity.

5 = 13 - 2.1*t

2.1*t = 13 - 5

t = (8)/2.1

t = 3.8 [s]

I hope this helps!! ( Sorry if my handwriting is hard to read, I´m working on making it neater at the moment. )

Answer:

(a) The magnitude of the force electric force F = k ×(+Q) × (-2·Q)/r₀² = -2·Q²/(r₀²) which can be written as follows;

[tex]F = \dfrac{k \times (+ Q) \times (-2\cdot Q)}{r_0^2} = -\dfrac{k \times 2 \times Q^2}{r_0^2}[/tex]

Given that the charge of Y is twice the charge on X, we have the charge X will move towards the charge Y which is the +x direction

(b) The force, F, acting between the charges is given as follows;

[tex]F = \dfrac{k \times Q_1 \times Q_2}{r_0^2}[/tex]

When, Q₁ = X = -4Q, Q₂ = Y = -2Q, and r₀ = 2·r₀ we have;

[tex]F = \dfrac{k \times (-4\cdot Q) \times (-2\cdot Q)}{(2 \cdot r_0)^2} = \dfrac{k \times 8 \times Q^2}{4 \cdot r_0^2} = \dfrac{k \times 2 \times Q^2}{r_0^2}[/tex]

Therefore, the electric force exerted on object Y by the object X is the same and acts in an opposite direction to the force of X on Y in (a)

The net charge of the two objects in part (a) is Q - 2Q = -Q

The net charge of the two objects in part (b) is -4Q - 2Q = -6Q

Therefore, the net charge increases by a factor of 6 in part (b)

Explanation:

Answer:

the mathematical models, Newton's second law, improve the response of our designs and allow us to modify them to be more resistant.

Explanation:

When an object is designed it is done based on some models or guides, specifically Newton's second law is given in the form

            ∑ F = m a

We can make a design and test with forces applied in several different places and with different intensity, to find weak points in the design, this is done a lot today in the construction of tall buildings, in the design of airplanes; The great advantage of this is that it allows you to see problems without significant cost of money and human lives.

There are also designs that can be modified to improve the response of our system to different external stimuli, this is widely used in the design of bridges, to see the response of the structure before load changes and different climatic conditions.

In summary, the mathematical models, Newton's second law, improve the response of our designs and allow us to modify them to be more resistant.
