Answer:

The right approach will be "47° north of east".

Explanation:

The given values are:

East of prison

= 1.70 km

Displacement vector

= 2.50 km

Now,

The direction will be:

⇒  [tex]Cos \ \theta =\frac{1.7}{2.5}[/tex]

⇒            [tex]=0.68[/tex]

⇒         [tex]\theta=47.16^{\circ}[/tex]

i,e.,       [tex]\theta = 47^{\circ}[/tex] (north of east)

The direction of his total displacement vector with respect to due East is 1.83km

Given the following parameters

Distance ran through east = 1.70km

displacement = 2.50km

Required

Total displacement vector with respect to due north

Using the expression below;

d = √x² + y²

2.5² = 1.7² + y²

y² = 2.5² -  1.7²

y² = 3.36

y = 1.83km

Hence the direction of his total displacement vector with respect to due East is 1.83km

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]

There is potential energy in your leg that once comes in contact with the ball turns into kinetic energy.

Answer:

it is A

Explanation:

because energy can neither be created nor destroyed - only converted from one form of energy to another.

Answer:

Latitude :

runs: east to west

measures : distances north and south of the equator

Longitude :

runs : north to south

measures : the distance east or west of the Prime Meridian

Case 1 has the greatest strength for the push and pull. Option A is correct.

The pushes and pulls the body experiences are referred to as force. It can occasionally be used to alter the body's size, shape, and direction.

Mass times acceleration equals force, according to the definition. Newton is its measure.

The force transmitted through a rope, string, or wire as it is tugged by opposing forces is referred to as the tension force.

Energy is drawn equally from both ends by the tension force, which is exerted along the whole length of the wire.

The tension force is acting in the rope causing greater strength for the push and pull.

Hence, option A ia correct.

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

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.

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.

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.

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.

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;

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.

Answer:

Temperature, density

Explanation:

Physical properties of a substance are those properties that do not change the chemical composition of the substance. There are two types of physical properties namely: intensive property and extensive property.

Intensive properties are those physical properties that does not depend on the sample size of the substance involved. Examples of intensive physical properties are temperature, density, boiling point. For example, the size or amount of a substance does not determine the the TEMPERATURE or BOILING POINT of the substance.

Answer:

The 2 forces are a Push and a Pull

Mass is the resistance of change in speed or position when adding force.

Weight is the force of gravity

Tension Force is the pulling force transmitted through a string cable or chain. The formula for this is T = mg + ma.

It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.

An unbalanced force is when there is 2 forces on opposites of an object both are adding force but one side is stronger than the other.

Friction is a force that heats things up. This happens when we rub our hands together and the heat that is generated from the friction makes our hands warmer.

Static friction is what keeps the box from moving without being pushed, and it must be overcome with a sufficient opposing force before the box will move. Kinetic friction (also referred to as dynamic friction) is the force that resists the relative movement of the surfaces once they're in motion.
