A block of wood has a mass of 8 g and occupies a volume of 10 cm3. What is its density?

Answers

Answer:

0.8 g/cm³

Explanation:

recall that the definition of density is the mass per unit volume of an object.

or mathematically:

density = mass / volume

here we are given that mass = 8 g and volume = 10 cm³

hence,

density = 8 g / 10cm³ = 0.8 g/cm³

The block has a mass of 8 g with a volume of 10 cm³. It density is mass divided by volume that is 0.8 g/cm³.

What is density?

Density of a substance is the measure of  its mass per unit volume. Density is dependent on some other factors beside mass and volume such as bond type, temperature and pressure.

The ratio of density of a substance to the density of water is called its specific gravity. If the substance is denser than water it will sink on water otherwise it will float on it.

The mass of the block of wood = 8 g

volume = 10 cm³

Density = mass / volume

              = 8 g/ 10 cm³

              = 0.8 g/ cm³

Therefore, the density of the wood block is 0.8 g/ cm³.

As the cloud passes over the building, a lightning strike occurs and a charge of 0.84C flows through the lightning conductor. The charge flows for 3.5 × 10^-5 s.
Calculate the average current in the lightning conductor during this time. State the formula used in your answer

Answers

Answer:

I=24,000 Amp

Explanation:

Electric Current

Is a measure of the quantity of charge Q flowing by a point in a time period of t.

The standard metric unit for the current is the Ampere, often abbreviated as Amps or A.

It can be calculated as:

[tex]\displaystyle I=\frac{Q}{t}[/tex]

The cloud generates a lightning strike that releases a charge Q=0.84 C during a time [tex]t=3.5\cdot 10^{-5}\ sec[/tex].

The current is of course, not of a constant value, but an average value can be calculated by using the above formula:

[tex]\displaystyle I=\frac{0.84}{3.5\cdot 10^{-5}}[/tex]

[tex]\boxed{I=24,000\ Amp}[/tex]

Rock X is released from rest at the top of a cliff is on earth. A short time later, Rock y is released from rest from the same point as rock X. Both rocks fall for several seconds before landing on the ground directly below the cliff. Frictional forces are considered to be negligible. Which of the following graph correctly shows the vertical velocity of rock X as a function of time? Take the positive direction to the upward.​

Answers

Answer:

The graph that correctly shows the vertical velocity is B. since the velocity is negative and increases linearly over time

Explanation:

When an object is dropped from rest its movement is ruled only by the effect of gravity.

The acceleration of gravity [tex]g=9.8\ m/s^2[/tex] makes the object gain speed with a linear relation as shown:

vf = g.t

If we take the positive direction to be upward, then the speed will always be negative since the object will go against the positive direction.

Thus, the graph that correctly shows the vertical velocity is B. since the velocity is negative and increases linearly over time

From the given graphs, only the second graph (option B) started from rest (0) and later increased with time.

The given parameters;

Rock XRock yinitial velocity of Rock X = 0

The final vertical velocity of the rock X after a short time "t" is calculated as follows;

[tex]v_y_f = v_y_i + gt\\\\v_y_f = 0 + 9.8t[/tex]

The vertical velocity of the rock x will increase with time as it moves downwards.

Therefore, we can conclude that, from the given graphs, only the second graph (option B) started from rest (0) and later increased with time.

How can two different nonmetals form a compound?

Answers

Explanation:

Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.

Nonmetals can form compounds through a process called covalent bonding.

Covalent bonding occurs when two nonmetal atoms share electrons to achieve a stable electron configuration. This sharing of electrons allows both atoms to fill their outermost energy levels or achieve a noble gas electron configuration.

When two nonmetal atoms come together to form a compound, their electronegativities play a crucial role. Electronegativity is the ability of an atom to attract electrons toward itself in a chemical bond. If the electronegativities of the two nonmetals are similar, they will have a similar tendency to attract electrons, resulting in a more equal sharing of electrons.

So, nonmetals can form compounds through covalent bonding by sharing electrons. The extent of electron sharing depends on the electronegativity difference between the nonmetals involved, leading to either polar covalent or ionic bonding.

Therefore, nonmetals can form compounds through a process called covalent bonding.

Both the X- and Y-components of a vector are doubled. Which of the following describes what happens to the resulting Vector?
a) Magnitude increases by √(2
b) Magnitude increases by √(2, and the direction changes
c) Magnitude increases by 2
d) Magnitude increases by 2, and the direction changes

Answers

Answer: C. Magnitude increases by 2

Explanation:

If the magnitudes of X and Y vectors are increased, then the resultant vector will increase by a factor of 2 but the direction does not changes. Hence, option c is correct.

What is a vector ?

A vector is a physical quantity having both magnitude and direction. For example, force, velocity, work done, momentum, velocity etc. are vector quantities. The quantities which does not have direction are called scalar quantity.

The resultant vector R of vectors in X and Y direction can be written as follows:

[tex]\rm R = \sqrt{x^{2} + y^{2}}[/tex]

If the x and y components are doubled to 2x and 2y then the resultant vector becomes,

[tex]\rm R = \sqrt{(2x)^{2} + (2y)^{2}}\\\\ R = \sqrt{4 (x^{2} + y^{2})\\\\\\ R = 2 \sqrt{x^{2} + y^{2} \\ \\ \\ \\[/tex]= 2R

Therefore, the resultant vector will increases by 2 times. However the direction will not change. Hence, option c is correct.

A model rocket is launched from the ground. It starts from rest and accelerates upward at 15.0 m/s2 for 3.00 s. Disregard gravity. What is the V2? b. Then, it has a downward acceleration of -10.0 m/s2 until it reaches its highest point. What is the highest above the ground that the rocket gets? c. What is the TOTAL time in the air?

Answers

Answer:

The final velocity v₂ is 45 m/s

The highest point reached by the rocket is 101.25 m

The total time spent in air by the rocket is 7.5 s

Explanation:

Given;

initial velocity of the rocket, v₁ = 0

final velocity of the rocket, v₂ = ?

upward acceleration of the rocket, a = 15 m/s²

time of acceleration, t = 3 s

The final velocity is given by;

v₂ = v₁ + at

v₂ = 0 + (15 x 3)

v₂ = 45 m/s

The highest point reached by the rocket is given by;

v² = u² + 2ah

where;

u is the initial velocity of rocket when it started decelerating.

thus, u = v₂

v is the final velocity of the rocket at its highest point = 0

0 = v₂² + 2ah

0 = (45)² + (2 x -10 )h

0 = 2025 - 20h

20h = 2025

h = 2025 / 20

h = 101.25 m

Time taken for the rocket to reach its highest point is given by;

h = ut + ¹/₂at²

101.25 = 45t + ¹/₂(-10)t²

101.25 = 45t - 5t²

5t² - 45t + 101.25 = 0

t² - 9t + 20.25 = 0

t = 4.5 s

The total time spent in air by the rocket is given by;

T = upward time + downward time

T = 3 s + 4.5 s

T = 7.5 s
