Answer: B.  gravitation

Explanation:

Nebula is a stellar nursery. It is composed of dust and gases. This molecular cloud condenses under its own weight and forms a core which spins and gathers more mass due to gravity. This causes temperature and pressure to rise which kicks in the nuclear fusion reaction and a star is said to be born.

Thus, gravitation is responsible for formation of star.

What is the result of (6.2 × 10 4) x (3.3 × 10 2) expressed in scientific notation?

Answers

Final answer:

The multiplication of (6.2 × 10^4) by (3.3 × 10^2) results in 2.046 × 10^7, when expressed in scientific notation.

Explanation:

The result of the multiplication (6.2 × 104) × (3.3 × 102), expressed in scientific notation, involves multiplying the coefficients (6.2 and 3.3) and then adding the exponents of 10 (4 and 2). It's important to recall that we must perform both steps to arrive at the correct answer in scientific notation.

The product of the coefficients is 20.46 and when we add the exponents the result is 106. So the multiplication gives us 20.46 × 106, but in correct scientific notation, we want the coefficient to be between 1 and 10. To achieve this we adjust the coefficient to 2.046 and increase the exponent by 1, giving us the result: 2.046 × 107.

Chalk is an ionic compound. Which is a property of all ionic compounds that makes chalk particularly useful for writing on a chalkboard?

Answers

The Properties that make chalk particularly useful for writing are hardness and brittleness.

Answer:

Hardness and brittleness

Explanation:

Ionic substances form crystal lattices which allow the compounds to be hard because of the strong attractions between positive and negative ions in the lattice. When pressure is applied to the compound like chalk , it may force ions of the same charge together ( i.e. positive to positive). This is called electrostatic repulsion which is able to break the crystal lattice allowing one to write on the chalkboard.

The electrons that produce the picture in a

of 2.5 × 10^6 m/s.
What is their acceleration over this 1.6 cm
length?
Answer in units of m/s^2

.

Answers

Given:
u = 10⁵ m/s, the entrance velocity
v = 2.5 x 10⁶ m/s, the exit velocity
s = 1.6 cm = 0.016 m, distance traveled

Let a = the acceleration.
Then
u² + 2as = v²
(10⁵ m/s)² + 2*(a m/s²)*(0.016 m) = (2.5 x 10⁶ m/s)²
0.032a = 6.25 x 10¹² - 10¹⁰ = 6.24 x 10¹²
a = 1.95 x 10¹⁴ m/s²

Answer: 1.95 x 10¹⁴ m/s²

compare and contrast potential and kinetic energy

Answers

Kinetic Energy is moving energy. And potential energy is air G that has the potential to be movie or not moving at all
Final answer:

Potential energy is stored energy due to an object's position or state, while kinetic energy is the energy of an object in motion. They differ in their state, with potential energy being at rest and kinetic energy being in action. However, both can be transformed into each other.

Explanation:

Potential energy and kinetic energy are both forms of mechanical energy, but they are different in many ways. Potential energy is stored energy that an object has due to its position or state, like a rock perched at the top of a hill has gravitational potential energy. It has the potential to convert into kinetic energy but for now, it remains at rest.

On the other hand, kinetic energy is the energy of motion. An object in motion has kinetic energy— for example, a moving car or a flowing river has kinetic energy. Unlike potential energy, it is already in action. So the key difference is that potential energy is stored, while kinetic energy is in motion.

However, they are similar in that they both can be transformed into each other. For instance, when that rock on the hill begins to roll downhill, its potential energy is converting into kinetic energy.

How could a person easily tell which envelope contained four sheets of paper and which contained five sheets without opening the envelopes what assumption did you make in arriving at your answers

Answers

You can easily tell by shaking the envelope by making the sheets inside it overlap then flip it around then start feeling then you can feel 4 sheets
Final answer:

You could tell the difference between two envelopes containing 4 and 5 sheets of paper by comparing their weights. An envelope with 5 sheets should feel heavier than the one with 4 sheets, assuming that all materials involved are identical.

Explanation:

One way to tell the difference between two envelopes containing 4 and 5 sheets of paper without opening them would be to use weight as a distinguishing factor. Given that the weight of paper is constant, one sheet of paper would add a perceivable amount of weight to an envelope. Therefore, the envelope with 5 sheets should be heavier than the envelope containing 4 sheets. The assumption here is that both the envelopes and the sheets of paper are identical in every other aspect including size, material, weight, etc.

In theory, if you were to hold each envelope in either hand, the difference in weight should be detectable. It's a common practice in mailrooms where workers are adept at figuring out the number of papers inside envelopes just by weight comparison. This method, however, requires a certain level of sensitivity and practice. The real application of this method can vary based on multiple factors such as individual's sensitivity to weight change, uniformity in the weight of the paper etc.

Suppose a car is traveling at +25.0 m/s, and the driver sees a traffic light turn red. After 0.340 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 7.00 m/s2.

Answers

First, we will get the distance traveled before the driver applied the brakes.
distance = velocity * time
distance = 25*0.34 = 8.5 m

Now, we will calculated the distance that the car traveled after the driver applied the brakes. To do this, we will use the equation of motion:
vf^2 = vi^2 + 2*a*d where:
vf = zero, vi = 25 m/s and a = -7 m/s^2
Note: The negative sign is only to show deceleration 
d =  1/2*(625) /(7) = 44.6428 m

The total stopping distance = 8.5 + 44.6428 = 53.1428 m

What does the phrase rise over run refer to when defining slope

Answers

I just learned this. Rise over run is also rise divided by run.  The rise refers to the y axis (since y is vertical so it's rising), and run refers to the x axis (Since x is horizontal so it's running straight).  So in other words, rise/run = y/x.  To calculate the slope, you do y/x.  For example, if you have y=3 and x=8, then your slope is 3/8.  To plot that on a graph, you start from your point, and go up three, and across 8.  Hope this helps.

a swimmer can swim in still water at a speed of 9.50 m/s. he intends to swim directly across the river that has a downstream current of 3.75 m/s. what is his velocity relative to the bank?

Answers

Refer to the diagram shown below.

Still-water speed  = 9.5 m/s
River speed = 3.75 m/s down stream.

The velocity of the swimmer relative to the bank is the vector sum of his still-water speed and the speed of the river.

The velocity relative to the bank is
V = √(9.5² + 3.75²) = 10.21 m/s

The downstream angle is
θ = tan⁻¹ 3.75/9.5 = 21.5°

Answer:  10.2 m/s at 21.5° downstream.

The relative velocity of swimmer to the bank is [tex]\boxed{10.21\text{ m/s}}[/tex] and [tex]\boxed{21.54^\circ}[/tex] downstream.

Further Explanation:

The swimmer swims across the river from one end to the other. The river is flowing downstream.

The swimmer will cross the river with some relative velocity.

Given:

The velocity of swimmer is [tex]9.50\text{ m/s}[/tex].

The velocity of river is [tex]3.75\text{ m/s}[/tex] downstream.

Concept:

Consider the direction of velocity of swimmer in positive x-direction.

The velocity of swimmer in vector form:

[tex]V_s=9.50\hat i[/tex]

Consider the direction of downstream current of river in negative y-direction.

The velocity of downstream current in vector form:

[tex]V_r=- 3.75\hat j[/tex]  

The relative velocity of swimmer to the bank is the resultant of two vectors in x and y direction.

Magnitude of relative velocity:

[tex]{V_{sr}}=\sqrt{V_r^2+V_s^2}[/tex]  

Substitute [tex]9.50\text{ m/s}[/tex] for [tex]V_s[/tex] and [tex]3.75\text{ m/s}[/tex] for [tex]V_r[/tex] in above equation.

[tex]\begin{aligned}{V_{sr}}&=\sqrt{3.75^2+9.50^2}\text{ m/s}\\&=10.21\text{ m/s}\end{aligned}[/tex]

The magnitude of relative velocity of swimmer is [tex]10.21\text{ m/s}[/tex] .  

The direction of relative velocity:

[tex]\theta={\tan^{-1}}\left({\dfrac{{{V_r}}}{{{V_s}}}}\right)[/tex]  

Substitute [tex]9.50\text{ m/s}[/tex] for [tex]V_s[/tex] and [tex]-3.75\text{ m/s}[/tex] for [tex]V_r[/tex] in above equation.

[tex]\begin{aligned}\theta&={\tan^{-1}}\left({\dfrac{{{-3.75}}}{{{9.50}}}}\right)\\&=21.54^\circ\end{aligned}[/tex]

The direction of relative velocity is [tex]21.54^\circ[/tex] downstream.

Thus, the relative velocity of swimmer to the bank is [tex]\boxed{10.21\text{ m/s}}[/tex] and [tex]\boxed{21.54^\circ}[/tex] downstream.

What is the relationship between height and gpe

Answers

Final answer:

The relationship between height and gravitational potential energy is directly proportional, following the equation G.P.E. = mgh. GPE increases as the height of an object increases, and it is measured in Joules, reflecting the energy due to the object's position above a reference level.

Explanation:

The relationship between height (h) and gravitational potential energy (GPE) is directly proportional. This means, as an object is raised to a higher elevation above the ground, its GPE increases. The formula for calculating GPE is G.P.E. = mgh, where m represents the mass of the object in kilograms, g is the acceleration due to gravity (approximately 10 m/s² on Earth's surface), and h is the height in meters. The unit of GPE is Joules, which quantifies the energy associated with the object's position in the gravitational field.

In physics, only the change in GPE (ΔGPE) is of significance, which is measured as the difference in energy when an object's height changes relative to a reference level. For instance, if a 0.500-kg mass from a cuckoo clock is lifted by 1.00 m, its GPE changes by mgh. The concept of GPE is vital in various applications, including understanding how energy is conserved within systems influenced by gravitational forces.
