Which of the following is NOT true of a hotspot?

Answers

Given what we know about hotspots and their characteristics, we can confirm that the option that is false regarding hotspots is "A. Hotspots are constantly moving forming chains of volcanoes".

In regards to the study of geology, we refer to hotspots as spots in an oceanic mantle where magma located below causes them to become intensely hot. This heat forces magma and therefore the mantle itself upwards as a tectonic plate moves across the spot, and therefore results in the formation of volcanic chains. Some very popular examples of volcanoes and volcanic islands formed by this method include:

Yellowstone National ParkHawaiiThe country of Iceland

Despite the other options being true, option A is false given that hotspots are stationary elements of the oceanic mantle. Although some scientists believe that there is evidence of the movement of hotspots, this movement is slow enough to not be taken into account.

This question was answered in regards to the complete question found online which states:

Which of the following is NOT TRUE about hotspots? a. Hotspots are constantly moving forming chains of volcanoes.

b. Hotspots are stationary.

c. Hotspots form volcanic island arcs

d. Hotspots lie along an oceanic plate

A 16.75 g piece of iron absorbs 986.75 joules of heat energy, and it’s temperature changes from 25 degrees Celsius to 175 degrees Celsius. Calculate the specific heat capacity of iron.

Answers

Answer:

0.39 J/g°c

Explanation:

= heat / unit of mass × unit of temperature

986.75J/16.75g

= 58.9 J/g

T=175°c - 25°c = 150°c

986.75 / 150°c = 6.578

986.75 / 16.75g.150°c = 0.30 j/c

Answers

Answer: 225N to the right

Explanation:

The pedaling force is to the right and of 325N.

The air resistance is to the opposite side (in this case to the left) of 100N.

To find Net force of an object with two opposite forces acting on them then we have to subtract the smaller force from the bigger force and but the direction of the bigger force, so

325N-100N=225N

The greater force is towards the right proving the direction of the Net force is to the right.

Therefore the Net force is 225N to the right.

Dave and Alex push on opposite ends of a car that has a mass of 875 kg. Dave pushes the car to the right with a force of 250 N, and Alex pushes to the
left with a force of 315 N. Assume there is no friction.
What is the net force on the car in the x-direction? Help meee please

Answers

The net force acting on the car is 65 N to the left

The net force acting on an object is simply defined as the resultant force acting on the object.

From the question given, we obtained the following data:

Force applied to the right (Fᵣ) = 250 NForce applied to the left (Fₗ) = 315 NNet force (Fₙ) =?

The net force acting on the car can be obtained as follow:

Fₙ = Fₗ – Fᵣ

Fₙ = 315 – 250

Fₙ = 65 N to the left

Therefore, the net force acting on the car is 65 N to the left

Since there is no friction, the net force on the car in the x - direction will be 65 Newtons

Given that Dave and Alex push on opposite ends of a car that has a mass of 875 kg.

Dave pushes the car to the right with a force of 250 N, which is positive direction and Alex pushes to the left with a force of 315 N which is negative direction. Since there is no friction, only the horizontal forces will be considered.

To calculate the net force on the car in the x-direction, we will find the difference between the two forces because of their directions are opposite to each other.

Net force = 315 - 250

Net force = 65 Newtons

Therefore, the net force on the car in the x - direction will be 65 Newtons

These people load 10 items on the truck in 10 minutes. What are ways power can be increased?

Answers

The power can be increased by decreasing the time it takes to load 10 items into the truck it can be done by using leverage and putting more boxes in the truck at the same time.

What is power in physics?

Power refers to the ability of doing work done per unit time, higher the power means more work has been done in less time. The SI unit of power is watt.

What is work done?

Work done is a physical quantity that refers to measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.

Given:

10 people are loading 10 items in a truck

According to the question we have to maximize the power output.

To do this we need to increase work done per unit time. This can be done in a number of ways which include:

Using leverage and pulley techniques to increase the loading capacity of the individual, so that more work is done in less time and therefore increasing the power output of the work to be done.

The second method would be decreasing the time it takes to load the boxes into the truck which can be done if multiple boxes are loaded into the truck at the same time.

Therefore, the power can be increased by decreasing the time it takes to load 10 items into the truck it can be done by using leverage and putting more boxes in the truck at the same time.

A 1,500 kg car’s speed changes from 30 m/s to 15 m/s after the brakes are applied. Calculate the work done onto the car from the brakes.

Answers

The work done onto the car is 506,250 J

The work done on a system implies an increase in the internal energy of the system as a result of some forces acting on the system from the outside.

From the parameters given:

The mass of the car = 1500 kgThe initial speed = 30 m/sThe final speed = 15 m/s

The work done onto the car refers to the change in the kinetic energy (i.e. ΔK.E)

[tex]\mathbf{=\dfrac{1}{2} mv_1^2 -\dfrac{1}{2} mv_2^2}[/tex]

[tex]\mathbf{=\dfrac{1}{2} m(v_1^2 - v_2^2)}[/tex]

[tex]\mathbf{=\dfrac{1}{2} \times 1500 \times (30^2 - 15^2)}[/tex]

= 506,250 J

Therefore, we can conclude that the work done on the car is 506,250 J
