As a parachutist falls with his parachute open, the downward force from the gravitational interaction is the same strength as the upward force of the drag interaction.


b. How would you describe the Forces? Explain whether or not the parachutist is accelerating.

As A Parachutist Falls With His Parachute Open, The Downward Force From The Gravitational Interaction

Answers

Answer 1

Answer:

the forces are equal and the parachutist is not accelerating.

Explanation:

since the downward and upward forces are the same, the parachutist will not move up or down, so they are not accelerating.

i hope this helps! :D

Which ocean floor feature is responsible for creating the largest mountain ranges in the world?

Which ocean floor feature is responsible for creating new land? Which is responsible for destroying land?

Answers

Answer:

In fact, the tallest mountains and deepest canyons are found on the ocean floor; far taller and deeper than any landforms found on the continents.

Rising up from the abyssal plain, you would encounter the mid-ocean ridge, an underwater mountain range, over 40,000 miles long, rising to an average depth of 8,000 feet. Tracing their way around the global ocean, this system of underwater volcanoes forms the longest mountain range on Earth.

Underwater landforms · Continental shelf Abyssal plains Mid-ocean ridge Ocean trenches Plate tectonics and the ocean floor Hydrography.

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

At the deep-sea trenches, two plates converge, with one plate sliding down under the other into the mantle where it is melted. Thus, for each segment of new ocean floor created at the ridges, an equal amount of old oceanic crust is destroyed at the trenches, or so-called subduction zones.

What type of energy conversion happens when you draw a picture on the floor?
a. Chemical to thermal to electrical. b. Thermal to mechanical to chemical.
c. Mechanical to chemical to thermal. d. Chemical to mechanical to thermal.

Answers

Answer:

B.

Explanation:

Ur welcome

When a picture is drawn on the floor, chemical energy is converted to mechanical energy and then to thermal energy.

What is thermal energy?

Thermal energy is defined as a type of energy which is contained inside a system and is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.

Thermal energy arises as a result of  friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance has  molecules or atoms which are vibrating faster.

These vibrating molecules and atoms collide with each other and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.

the defense between an earthquake's focus and its epicenter.

Answers

Answer: The focus is the place inside Earth's crust where an earthquake originates. The point on the Earth's surface directly above the focus is the epicenter. The epicenter is the point on the surface above the focus, the place on the surface that would receive the most intense vibrations.

Explanation: Hope it helps <3

The focus is the point within the earth where seismic waves originate; it is centered on the part of the fault that has the greatest movement. The epicenter is on the earth's surface directly above the focus.

(I NEED THE ANSWER ASAP)

Answers

Answer:

Convection is heat transfer due to a density differential within a fluid

Example:

The current begins when the air over the hot sand is heated and begins to rise because of its lowered density. Air from above the ocean is colder and more dense. This cooler air takes the place of the rising hot air from over the sand

Could it be possible to run at the speed of sound with some future tool

Answers

Maybe in the future but now no. The fastest a human could run, according to most studies is about 36–40mph, and sound in dry air travels at about 760+ mph. That's considerably faster, almost 20 times actually. The reason why we couldn't ever run anywhere close to 760mph is because human muscles can't conract that fast.

Answer:

Scientists have discovered the fastest possible speed of sound. ... the absolute speed limit at which a wave can travel which is the speed of light
