A passive continental margin has a continental rise, while an active margin does not. Therefore, option A is correct.
What is passive continental margin?Where there is no plate border to mark the transition from land to sea, this is known as a passive continental margin.
A good example is the east coast of the United States, where the plate boundary is a distance from the shore along the mid-Atlantic ridge. Little geological activity occurs along passive borders.
Volcanoes, mountain belts, and earthquakes all identify active margins. They lack a continental uplift and an abyssal plain, in contrast to passive margins.
The Pacific and North American Plate boundaries are visible along the west coast of the United States, which is an example of an active margin. Where there is no plate border to mark the transition from land to sea, this is known as a passive continental margin.
Thus, option A is correct.

A spring has a force constant of 40000 N/m.
How far must it be stretched for its potential energy to be 42 J?
Answer in units of m
Answer:
0.05m
Explanation:
Given parameters:
Force constant of the spring = 40000N/m
Potential energy = 42J
Unknown:
Extension = ?
Solution:
To solve this problem, use the expression below:
E.PE = [tex]\frac{1}{2}[/tex] k e²
k is spring constant
e is the extension
42 = [tex]\frac{1}{2}[/tex] x 40000 x e²
e = 0.05m

What is the current produced by a 9-volt battery flowing through a resistance of 0.2 ohms?
Answer:
45 AmpereExplanation:
R=V/I I=V/R V = 9 R=0.2 I = 9/0.2 = 9×10/0.2×10 =90/2 ie, I =45 AThe current produced by a 9-volt battery flowing through a resistance of 0.2 ohms would be 45 Ampere.
What is resistance?
Resistance is the obstruction of electrons in an electrically conducting material.
The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.
V=IR
As given in the problem we have to find the current produced by a 9-volt battery flowing through a resistance of 0.2 ohms.
current produced by a 9-volt battery = voltage /resistance
= 9 volt /0.2 ohms
= 45 Ampere
Thus, the current produced would be 45 Ampere.

Why is mineral copper often used to make electrical wires
Because copper is the second-best electrical conductor, it's cheaper and more plentiful than silver, and it's relatively easy to get it out of the ground, refine it, and form it into wires.
(If the electrical wiring in your house was all silver wire, I guess nothing would ever work, because people would keep stealing your wiring.)

A student mixes two substances in a large beaker. After two hours, the student sees that the substances have separated again.
The full question is found in the image attached
Answer:
Densities
Explanation:
When we talk about density, one of the things that come to our mind is actually how heavy something is.
If i have substances that possess different densities, i will notice that i can not really mix them because they will separate and the heavier substance will be at the bottom while the lighter substance will be at the top.
Hence the two substances separated due to difference in density.

The formation of new elements through the process of fusion in a star’s core stops at iron. How are elements larger than iron formed?
Answer:
During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced. In the supernova explosion, all of these elements are expelled out into space.

Ek = 12 x m X v2. Re-arrange to give an equation for:
a) The mass m.
b) Velocity squared v2.
c) Velocity.
Answer:
a) [tex]m = \frac{2\cdot E_{k}}{v^{2}}[/tex], b) [tex]v^{2} = \frac{2\cdot E_{k}}{m}[/tex], c) [tex]v = \sqrt{\frac{2\cdot E_{k}}{m } }[/tex]
Explanation:
a) Translational kinetic energy ([tex]E_{k}[/tex]), measured in joules, is represented by the following expression:
[tex]E_{k} = \frac{1}{2}\cdot m \cdot v^{2}[/tex] (1)
Where:
[tex]m[/tex] - Mass, measured in kilograms.
[tex]v[/tex] - Velocity, measured in meters per second.
Now we clear the mass within the formula:
[tex]E_{k} = \frac{1}{2}\cdot m\cdot v^{2}[/tex]
[tex]2\cdot E_{k} = m\cdot v^{2}[/tex]
[tex]m = \frac{2\cdot E_{k}}{v^{2}}[/tex]
b) Now we clear the velocity squared:
[tex]v^{2} = \frac{2\cdot E_{k}}{m}[/tex]
c) Now we clear the velocity:
[tex]v = \sqrt{\frac{2\cdot E_{k}}{m } }[/tex]
