Which three terms are needed to describe the energy a BASE jumper has as she falls toward the ground?

Answer:

Explanation:

The sphere would have a greater change in volume, because its shape is more spherical, meaning it has more surface area and therefore more space for expansion. The cube, on the other hand, has less surface area, so its increase in volume would be less.

The lens must be moved by 22.3 mm to change the focus of the camera from a person 25 m away to one that is 4.0 m away.

We can use the thin lens equation to solve this problem:

1/i + 1/o = 1/f

where i is the image distance, o is the object distance, and f is the focal length of the lens. At the initial position, the object distance is 25 m, so we can write:

1/i + 1/25m = 1/40mm

Solving for i, we get:

i = 27.8 mm

At the new position, the object distance is 4.0 m, so we can write:

1/i' + 1/4.0m = 1/40mm

Solving for i', we get:

i' = 5.5 mm

The change in position of the lens, Δx, is equal to the difference in image distances:

Δx = |i - i'| = |27.8 mm - 5.5 mm| = 22.3 mm

Only the charge present inside the cavity can explain the electric field that exists there. The electric field inside the hollow would remain unchanged as a result.

Each point in space has an electric field associated with it when there is charge present in any form. E, often known as electric field strength, electric field intensity, or just the electric field, is a mathematical constant that expresses the strength and direction of an electric field. To predict what would happen to electric charges nearby a specific point, one only needs to be aware of the value of the electric field there, without having any precise knowledge of what generated the field.

When one charge is thought of as the generator of an electric field that spreads outward into the surrounding space, the electric force is not thought of as a direct interaction of two electric charges that are separated from one another.

The satellite travels approximately 1,798.07 km in 1 hour. The circumference of the satellite's orbit is 8,600π km, and the satellite orbits Mars every 15 hours.

To find out how far the satellite travels in 1 hour, we need to determine its orbital circumference.

The circumference of a circular orbit can be calculated using the formula:

C = 2πr

where C is the circumference and r is the radius of the orbit.

In this case, the satellite is orbiting Mars, which has a radius of approximately 3,300 km. The satellite is 1,000 km above the surface of Mars. Therefore, the radius of the satellite's orbit is the sum of the radius of Mars and the distance above the surface:

r = 3,300 km + 1,000 km = 4,300 km

Now we can calculate the circumference:

C = 2π(4,300 km) = 8,600π km

Since the satellite orbits Mars every 15 hours, the distance traveled in 1 hour is 1/15th of the circumference:

\(\begin{equation}\text{Distance traveled in 1 hour} = \frac{1}{15} \cdot 8600\pi \text{ km}\)

Calculating this value gives us:

Distance traveled in 1 hour ≈ 1,798.07 km

Therefore, the satellite travels approximately 1,798.07 km in 1 hour.

The rate at which a certain balloon travels is inversely proportional to the amount of weight attached to it if the balloon travels at 10 in./s and then there is a 2nd g weight attached to it approximately the weight must be attached to the balloon for it to travel 18 in./s is 1.1 grams.

When 2 grams are added, the rate moves at 10 in/sec.

Since the weight and the distance traveled are inversely proportional, the expression can be written as

d= k/W

10 =k/2

k= 20

When 2 grams are attached, the rate moves at a speed of 10 in/second.

Given that the relationship between the weight and the traveled distance is inverse, this can be expressed as,

d= k/W

Answer:

The total distance between A and B is 30 km

Explanation:

The given information are;

The time duration of the acceleration of the train from station A = 3 minutes = 0.05 hours

The speed attained by the train after the acceleration = 144 km/h

The time duration the train maintains the speed = 10 minutes = 0.1\(\bar 6\) hours

The time duration in which the train decelerates to station B = 2 minutes = 0.0\(\bar 3\) hours

The equation of motion required are;

The initial acceleration, a = (144 - 0)/0.05 = 2,880 km/h²

The distance covered, s = u·t + 1/2·a·t²

Where;

u The initial velocity = 0

∴ s₁ = 0 × 0.05 + 1/2 × 2880 × 0.05² = 3.6 km

s₁ = 3.6 km

The distance, s₂ the train covers at the constant speed 144 km/h for 10 minutes (1/6 hours) is given as follows;

s₂ = Velocity Time = 144 × 1/6 = 24 km

s₂ = 24 km

The deceleration, a₂ that brings the train to a stop in 2 minutes (1/30 hours) is given as follows;

a₂ = (0 - 144)/(1/30) = -4320 km/h²

The distance covered, s₃ by the train as it decelerates to rest from the initial constant speed is given as follows;

s₃ = u·t + 1/2·a·t²

Where;

u = The initial velocity =144 km/h

We have;

s₃ = 144×1/30 - 1/2 × 4320 × (1/30)² = 2.4

s₃ = 2.4 km

The total distance between A and B, s = s₁ + s₂ + s₃ = 3.6 + 24 + 2.4 = 30 km

The total distance between A and B = 30 km.

The correct answer is that the magnitude of the force F3 applied to the third box is equal to the magnitude of the force F1 applied to the first box.

The magnitude of the force F3 that the handler applies to the third box can be compared to the magnitude of the force F1 applied to the first box by using the equation F = ma.

For the first box, the force F1 is equal to the mass of the box (m) multiplied by the acceleration of the box (a), or F1 = ma.

For the third box, the force F3 is equal to the mass of the box (m/2) multiplied by the acceleration of the box (2a), or F3 = (m/2)(2a).
Simplifying the equation for F3 gives us F3 = ma.

Therefore, the magnitude of the force F3 applied to the third box is equal to the magnitude of the force F1 applied to the first box.
In other words, F3 = F1.

A person seated on a tree branch can be at rest with reference to various objects or frames of reference, depending on what is being considered as the fixed point.

For example, if we consider the person as being at rest with respect to the tree branch, then the branch and the person are in the same reference frame, and the person is stationary with respect to the branch.

If we consider the person as being at rest with respect to the ground, then the person's velocity relative to the ground is equal to the velocity of the tree branch relative to the ground. This means that if the branch is stationary with respect to the ground, then the person is also stationary with respect to the ground. If the branch is moving with respect to the ground, then the person is also moving with the same velocity as the branch relative to the ground.

In addition, the person may also be at rest with respect to the surrounding environment, such as the air, nearby objects, or the Earth's gravitational field.

Based on the given information, the most appropriate classification for the state of the volcano would be "Active-Dormant."

The volcano's history of generating multiple lava flows over the past 10,000 years indicates that it has been active in the relatively recent past. The presence of lava flows that have spread over large areas suggests ongoing volcanic activity, although not necessarily in the immediate present.

Additionally, the mention of very little tephra (volcanic ash and fragments) indicates that the volcano is not currently experiencing explosive eruptions. Instead, it has been primarily characterized by effusive eruptions that produce lava flows.

The fact that people in the nearby town remember the last eruption, which caused some forest fires, further supports the classification of the volcano as active-dormant. While the volcano may not be actively erupting at the moment, the memory of the recent eruption and the potential for future volcanic activity suggests that it is still in a state of activity, albeit in a relatively dormant phase.

Answer:

The hikers average speed due north is 0.2 km per minute.

Explanation:

Speed is the ratio of distance moved by a body to the time taken.

i.e speed = \(\frac{distance}{time}\)

Since the hiker walks due north and due west, then his average speed due north can be determined by;

Average speed = \(\frac{total distance due north}{total time taken}\)

Total distance due north = 5.0 + 7.0

                                  = 12.0 km

Total time taken = 20 + 40

                           = 60 minutes

                           = 1 hour

Average speed due north= \(\frac{12}{60}\)

                          = \(\frac{1}{5}\)

                          = 0.2

Average speed due north = 0.2 km/minute

The hikers average speed due north is 0.2 km per minute.

It's important to note that the time required for bed accumulation can vary greatly depending on the specific depositional setting and the geological context. Therefore, while thick beds generally suggest longer deposition periods, the exact relationship between bed thickness and time can be influenced by a range of geological factors.

The time required for the accumulation of sedimentary beds, whether thick or thin, can vary depending on various factors. Thick beds generally represent a longer period of sediment deposition compared to thin beds or laminations. This is because thick beds typically result from the continuous or episodic deposition of sediment over an extended period of time, whereas thin beds or laminations may form more rapidly or in a shorter time span.

The formation of thick beds can be influenced by factors such as sediment supply, depositional environment, and sedimentation rates. For example, in environments with high sediment input, such as river deltas or turbidite systems, thick beds may accumulate relatively quickly due to the large volume of sediment being transported and deposited.

On the other hand, thin beds or laminations often result from more rapid or intermittent sedimentation processes. These thinner layers can be associated with processes like periodic flooding events, storm deposition, or the settling of fine-grained sediments in calm environments.

The event that does not take place in the light reactions is the synthesis of glucose.

The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplasts and involve the capture and conversion of light energy into chemical energy in the form of ATP and NADPH. The primary events that take place in the light reactions include the absorption of light by chlorophyll, the generation of ATP through photophosphorylation, and the production of NADPH through the transfer of electrons.

One of the key products of the light reactions is ATP, which serves as an energy carrier. ATP is generated through the process of chemiosmosis, where the energy from light is used to pump protons across the thylakoid membrane, creating an electrochemical gradient. This gradient drives the synthesis of ATP by ATP synthase.

Another important product of the light reactions is NADPH, which is an electron carrier. NADPH is formed when light energy is used to excite electrons in chlorophyll, which are then passed through a series of electron carriers, ultimately reducing NADP+ to NADPH.

However, the synthesis of glucose, a carbohydrate molecule, does not occur in light reactions. Glucose synthesis takes place during the subsequent dark reactions, also known as the Calvin cycle or the light-independent reactions, where carbon dioxide is fixed and converted into glucose using the ATP and NADPH produced in the light reactions.

In summary, the event that does not take place in the light reactions of photosynthesis is the synthesis of glucose. Glucose synthesis occurs in the subsequent dark reactions of photosynthesis.
