Plate boundaries
Answer:
The answer is E., or "Plate Boundaries".
The word best describes the definition of the location of volcanoes is "plate boundaries". Therefore, option (E) is correct.
What are plate boundaries?The lithosphere is broken into tectonic plates that undergo some large motions and the boundary regions between plates are called plate boundaries. Based on their motions there are three kinds of plate boundaries: divergent, convergent, and transform.
Divergent boundaries are moving away from one another and separate, they form a rift. As the gap widens, the underlying layer may be soft for molten lava underneath to push upward and resulting in the formation of volcanic islands.
Convergent boundaries move towards one another and collide, subduction usually takes place. The denser plate goes underneath the less dense one and the plate boundaries also experience buckling.
Transform boundaries slide alongside one another and are exposed to huge amounts of stress and strain and are momentarily held in place. The two plates succeed in moving with respect to one another and cause earthquakes.

If at a particular instant and at a certain point in space the electric field is in the x-direction and has a magnitude of 5.00 V/mV/m, what is the magnitude of the magnetic field of the wave at this same point in space and instant in time
Answer:
the magnitude of the magnetic field of the wave is 16.7 nT
Explanation:
Given the data in the question;
Electric field E = 5.00 V/m
we know that the expression for the electric field of an electromagnetic wave in terms if magnetic field is;
E = cB
where c is the speed of light ( 3 × 10⁸ m/s )
and B is the magnetic field
so we solve for the magnetic field
B = E / c
we substitute in the value of E and c
B = (5.00 V/m) / (3 × 10⁸ m/s)
B = 1.67 × 10⁻⁸ T
B = 1.67 × 10⁻⁸ T [tex]( \frac{1nT}{10^{-9}T} )[/tex]
B = 16.7 nT
Therefore, the magnitude of the magnetic field of the wave is 16.7 nT

The density of table sugar is 1.59g/cm3 what is the volume of 7.85g of sugar?
Answer: 4.94cm³
Explanation:
Data;
ρ = 1.59g/cm³
mass = 7.85g
volume = ?
density = mass / volume
ρ = m / v
v = m / ρ
v = 7.85 / 1.59
v = 4.94cm³

Answer:
D
Explanation:
A certain object is subject to two forces: a 10-N force straight up and a 10-N force straight down. A student states that since both forces are in the vertical direction, the object cannot be moving horizontally. Why is this an incorrect conclusion?
A.
The vertical forces are balanced.
B.
Vertical net forces can cause horizontal motion.
C.
A horizontal force is not required for horizontal movement.
D.
Two vertical forces can combine to form a horizontal resultant force.
Answer:
C. Consider projectile motion. If an object starts out at some angle and only vertical forces (gravity) are present, the horizontal speed remains constant thruout the motion.
A p-n junction diode is, as the name suggests, an electronic device that is made up of a p-type semiconductor and an n-type semiconductor joined together.
a. True
b. False
Answer:
a. True
Explanation:
When a p-type semiconductor is placed adjacent to an n-type semiconductor the common plane thus formed is termed as P-N Junction or P-N Junction Diode.
The diode is formed by melting both p-type and n-type semiconductors through a special manufacturing process called "Thermo-Compression Proces".
The P-N junction has a property of one-way conduction. It means it only allows the current to pass through it in one direction and the current flow is practically zero in the other direction. Thus, it can act as a diode. The p-side acts as the anode, while the n-side acts as the cathode.
Hence, the correct option is:
a. True
An 800 kg charging bull rams through a wooden fence. It was travelling at
5 m/s, now it's travelling at 3 m/s. How much impulse did the bull
experience by smashing the fence?
Answer:
J = 1600 kg-m/s
Explanation:
Given that,
The mass of charging bull rams, m = 800 kg
Initial speed, u = 5 m/s
Final speed, v = 3 m/s
We need to find the impulse the bull experience by smashing the fence. Let it is J. We know that, impulse is equal to the change in momentum such that,
J = m(v-u)
Put all the values,
J = 800(3-5)
= 800(-2)
= -1600 kg-m/s
Hence, the magnitude of impulse is equal to 1600 kg-m/s.
