What happened to the supercontinents Columbia and Rodina?
They broke up and formed into the current land masses and
ocean floors.
The action of continental drift broke up Columbia an Rodina
into smaller continents.
The action of plate tectonics broke up Columbia and Rodina into
smaller continents.
They were formed before the process of plate tectonics began.

Answers

Answer 1

Explanation:

The choices aren't exactly correct. Technically, Rodinia pulled apart from tectonics, but then it slammed back together on the other side of the planet to form Pangea.

I guess C would be the closest correct answer.

Answer 2

Answer:

ocean floors.

What is the relationship between the frequency and the wavelength of a wave?

Answers

Answer: The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

A 35kg cannonball sits at rest on a flat level surface. What is the normal force exerted on the cannon ball. Use -9.8 m/s2 for acceleration due to gravity.

A. -343N

B. 44.8N

C. 25.2N

D. 343N

Answers

Answer:

a) N = 343 [N]

Explanation:

We must remember Newton's third law, which tells us that the force acting on a body is equal to the normal reaction force of equal magnitude but acting in the opposite direction.

[tex]N=m*g[/tex]

where:

m = mass = 35 [kg]

g = gravity acceleration = 9.81 [m/s²]

[tex]N = 35*9.8\\N= 343 [N][/tex]

Find the displacement of the object moving at v= -2 m/s for t=5s

Answers

Answer:

d = - 10 [m]

Explanation:

We must remember that speed is defined as the relationship between the displacement in a given time. In this way, we can propose the following equation.

[tex]v = d/t[/tex]

where:

v = velocity = 2 [m/s]

d = displacement [m]

t = time = 5 [s]

Now replacing:

Why doesn't the skateboarder roll as high each time she goes up the ramp

Answers

Answer:

The skater has mechanical/gravitational potential energy at the two meter mark. The skater gets to two meters high on the other end of the ramp. In terms of the conservation of energy, the skater will never go higher than two meter on the other end of the the ramp because energy can be neither created nor destroyed.

2. An 873 kg dragster accelerates at a rate of 44.6 m/s during a race.
a. What is the magnitude of the net force exerted on the dragster during this time?
Known (Given):
=
Unknown:
Fnet =
Equation:
Fret=ma (or m*a)
Solution:

Answers

Answer:

38,673.9N

Explanation:

According to newton's second law:

Force = mass * acceleration

Given

Mass = 873kg

acceleration = 44.66m/s²

Magnitude of the force is expressed as;

F = ma

F = 873 * 44.6

F = 38,673.9N

Hence the magnitude of the net force exerted on the dragster during this time is 38,673.9N

The surface of the Earth changes from processe such as erosion. Which of these changes to Earth's surface is an example of erosion? A. an active volcano starting to erupt B. a rock turning a red color from oxygen C. a waterfall breaking the rocks below it D. the wind picking up dust and carrying it

Answers

Answer:

D. the wind picking up dust and carrying it

Explanation:

Erosion is a process in which an agent transfer the top soil to another region, thereby exposing the lower soil. These agents have the ability to move the top layer of soil and deposit it at another place. The major agents in this case are; a running or flowing body of water and wind.

Therefore, the change to the Earth's surface that is an example of erosion is the wind picking up dust and carrying it. Thereby exposing the lower layers.

What is the force of gravity between two objects that are 4.0 m apart? The mass of the first object is 0.25 kg and the mass of the second object is 0.65 kg

Answers

Answer:

6.77 x 10^-13 Newtons

Explanation:

using the formula [tex]F= \frac{GMm}{r^2}[/tex]

where G is the gravitation constant which is 6.673 x 10^-11 N m2/kg2

M = mass of the first object which is 0.25 kg

m = mass of the second object which is 0.65 kg

and r is the distance between the objects which is 4 metres

Plugging our values in:

[tex]F\:=\:\left(6.673x10^{-11}\right)\frac{\left(0.25\right)\left(0.65\right)}{4^2}[/tex]

F = 6.77 x 10^-13 N

Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth. They are the building blocks of galaxies, of which there are billions in the universe. It’s impossible to know how many stars exist, but astronomers estimate that in our Milky Way galaxy alone, there are about 300 billion.
