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.
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:
Is The First One-They broke up and formed into the current land masses and
ocean floors.

The Washington Monument in our nation's capital is 555 ft high. Neglecting the effects of air resistance, what would be the
speed of the penny as it "hit" the ground?
оа

48.3 m/s
-68.4 m/s
84.7 m/s
-57.6 m/s
Answer:
a= g = - 9.81 m/s2.
The following equations will be helpful:
a = (vf - vo)/t d = vot + 1/2 at2 vf2 = vo2 + 2ad
When you substitute the specific acceleration due to gravity (g), the equations are as follows:
g = (vf - vo)/t d = vot + 1/2 gt2 vf2 = vo2 + 2gd
If the object is dropped from rest, the initial velocity ("vi") is zero. This further simplifies the equations to these:
g = vf /t d = 1/2 gt2 vf2 = 2gd
The sign convention that we will use for direction is this: "down" is the negative direction. If you are given a velocity such as -5.0 m/s, we will assume that the direction of the velocity vector is down. Also if you are told that an object falls with a velocity of 5.0 m/s, you would substitute -5.0 m/s in your equations. The sign convention would also apply to the acceleration due to gravity as shown above. The direction of the acceleration vector is down (-9.81 m/s2) because the gravitational force causing the acceleration is directed downward.
hope this info helps you out!

What is the relationship between the sizes
of the planets and their distances from the sun?
Answer:
The inner, rocky planets are smaller than the outer, gaseous planets
Explanation:
The relationship between the sizes of the planets and their distances from the Sun is: The smaller planets are closer to the sun while the bigger planets are farther from the sun.
A solar system can be defined as a collection of both the inner and outer planetary bodies alongside the Moon in orbit (travel) around the Sun, in slightly elliptical orbits.
Basically, the nine (9) planets of the solar system orbiting (traveling) in order of their distance around the Sun are;
Mercury.Venus.Earth.Mars.Jupiter.Uranus.Neptune.Pluto.Venus.Saturn.Basically, the relationship between the sizes of the planets and their distances from the Sun is that the smaller planets are closer to the sun while the bigger planets are farther from the sun.

A student buys a plastic dart gun and tries to find the maximum horizontal range. The student shoots the gun straight up and it takes 3.7 seconds for the dart to return back to the height of the barrel. What is the maximum horizontal range of the gun?
Answer:
The value is [tex]R_{max} = 33.54 \ m[/tex]
Explanation:
From the question we are told that
The total time of flight is [tex]t = 3.7 \ s[/tex]
Generally from kinematic equation
[tex]v = u - g * \frac{t}{2}[/tex]
So v is the velocity at maximum height and the value is v = 0 m/s
So
[tex]0 = u - 9.8 * \frac{ 3.7}{2}[/tex]
=> [tex]u = 18.13 \ m/s[/tex]
Here u is the initial velocity of the dart as it leaves that gun
Gnerally the horizontal range of the dart is mathematically represented as
[tex]R = \frac{u ^2 sin 2\theta }{g}[/tex]
For maximum horizontal range the value of [tex]\theta = 45^o[/tex]
So
[tex]R_{max} = \frac{ 18.13 ^2 sin 2(45) }{9.8}[/tex]
=> [tex]R_{max} = 33.54 \ m[/tex]

How much does a 20 kg rock weigh on Earth where g = 9.8 m/s2?
Answer:
[tex]\huge\boxed{196\:N}[/tex]
Explanation:
Mass and weight ain't the same thing. So, for calculating weight we would use Newton's 2nd Law of Motion i.e. Force = Mass × Acceleration.
According to question,
The mass is 20kg
Acceleration is 9.8 m/s^2
Putting the given values into the formula,
F = 20 × 9.8
F = 196N
So, the weight of the rock is 196 N

When you walk across the ground and push on it with your feet...
Group of answer choices
The ground pushes back more strongly than your feet
The ground pushes back on your feet with equal force
There is no effect on the ground
The ground pushes back less strongly than your feet
Answer:
The ground pushes back on your feet with equal force
Explanation:
When you walk across the ground and push on it with your feet, the ground pushes back on your feet with an equal and opposite force.
This interpretation and knowledge is gotten from Newton's third law of motion.
It states that "action and reaction force are equal and opposite in nature".
The force applied to a body responds with an opposite force in the other direction. Therefore, the reaction force is of equal magnitude but directed in another direction.Answer:
the answer is the second one: the ground pushes back on your feet with equal force

Form hypothesis: How do you think increasing the resistance in a circuit will affect the current in the wire? (format: if, then, because)
Answer:it would make it thicker
Explanation:
Answer:
"The equation shows that the current in a circuit is inversely proportional to the resistance of the circuit. An increase in resistance would result in a decrease in current. And the factor by which the resistance increases is the same factor by which the current decreases."
Explanation:
Because it's just like wearing a glove/mitten when getting something out of the oven, because of the insulation from the glove/mitten, it reduces the heat that gets through into your hand, and it protects it. Just like what the "answer" says, it said that the resistance would decrease current.

What is reflection of light and its laws ?
Answer:
So, put simply, reflection is light bouncing off surfaces. The law of reflection determines how the light bounces off a surface. The law of reflection states that the angle of incidence is equal to the angle of reflection.
Hope this helps..The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. (By convention, all angles in geometrical optics are measured with respect to the normal to the surface that is, to a line perpendicular to the surface.
