Lee knew that certain events occur to create new material in the process of sea-floor spreading. Rearrange the steps into the correct order by placing the event that happens first at the top. Place the event that occurs last at the bottom.
Answer:
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

What is the earth's crust?The Earth's Crust is the planet's outermost layer. The Crust is a portion of the lithosphere that lies above the mantle and comprises tectonic plates that provide a platform for all land on Earth.
We have:
Lee knew that certain events occur to create new material in the process of sea-floor spreading.
The correct order for in a breach in the Earth's crust, molten material pours upward:
The molten material hardens into solid strips of rock on both sides of the crack.The ocean floor on both sides of the crack moves farther away from the mid-ocean ridge.The ocean floor gradually becomes wider.Thus, the correct order for in a breach in the Earth's crust, molten material pours upward is (2), (3) and (4).

What is the momentum of a 4 kg object moving west at 4 m/s?*
O 12 kg*m/s (east)
O 1.33 kg*m/s (west)
O 16 kg*m/s (east)
16 kg*m/s (west)
Answer:
16kg*m/s west
Explanation:
P=M*V
Momentum= Mass time velocity, plug it into the formula,
M is 4 and V is 4, 4*4=16, and since the object is moving west its going to be west.
basically saying in simpler terms,
16=4*4

Samantha is identifying different minerals she found on vacation. Which property of the minerals will Samantha be LEAST able to determine by using only her eyes? A. Color B. Hardness C. Luster D. Texture
Answer: b
Explanation:
Given
Samantha is identifying different minerals by her eyes only. She will able to make a certain judgment for color, luster, and texture but not for hardness.
Hardness is the property of the material which tells about the resistance to the deformation. So, it is impossible to determine the hardness just by looking at the material. We need to perform certain tests like Brinell's hardness test, Vicker's hardness test.

A withered plant. Unless the plant is one of the many plants that have huge water retention capacity, for example, cactus. Such plants also don't need water to gr6, they just need a tiny amount of water, ba sufficient sunlight to enable them complete photosynthesis.
Any other plants asides one of the many like that, he will definitely come back to a dead, or at best, withered plant. A month is too long a time to not take care of your plant and expect it to still be up and running
a bullet of mass 120g is fired horizontally into a fixed wooden block with a speed of 20m\s. The bullet is brought to rest in a wooden block in 0.1secs by a constant resistance
calculate the;(I) magnitude of the resistance
(ii) distance moved by the bullet in the wood
Answer:
1) F = 24 N
2) Distance = 1 m
Explanation:
We are given;
Mass; m = 120 g = 0.12 kg
Initial velocity; u = 20 m/s
Final velocity; v = 0 m/s since it came to rest.
Time; t = 0.1 s
We can calculate acceleration from Newton's first equation of motion;
a = (v - u)/t
a = (0 - 20)/0.1
a = -200 m/s²
1) magnitude of the resistance will be;
F = ma
F = 0.12 × (-200)
F = -24 N
Since, we are dealing with the magnitude, we will take the absolute value. Thus, F = 24 N
2) To find the distance moved by the bullet, we know that;
Distance = Average speed × time
Thus;
Distance = ((v + u)/2) × t
Distance = ((0 + 20)/2) × 0.1
Distance = 1 m

The magnetic field of a bar magnet Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a Always points from north to south, whether we look outside the magnet or inside the magnet. b Always points from south to north, whether we look outside the magnet or inside the magnet. c Points from north to south outside the magnet, but south to north inside the magnet. d Points from south to north outside the magnet, but north to south inside the magnet.
Answer:
A: Always points from north to south, whether we look outside the magnet or inside the magnet
Explanation:
When we freely suspend a bar magnet, it's magnetic field will always rest in the north to south direction due to the fact that the Earth's magnetic south pole usually lies in the direction of the geographic north while the Earth's magnetic north pole usually lies in the direction of the geographic south.
Now, we all know that in magnets, like poles will repel and unlike poles will attract. What this now means is that the magnet will always point from the north to the south direction.

what is the relationship between harmonics and resonance frequency in a piano
There is direct relationship between harmonics and resonance frequency.
A harmonic is a wave with a frequency that is a positive integer multiple of the frequency of the original wave whereas, resonance frequency is the frequency at which the oscillation reaches to its maximum point. The lowest resonant frequency is known as the fundamental, while on the other hand, the higher resonant frequencies are called overtones. All resonant frequencies are multiples of the fundamental, and are called harmonics. So we can conclude that there is a direct relationship between harmonics and resonance frequency.Learn more about harmonic here: https://brainly.com/question/17315536

How can global warming lead to changes to the Earth’s surface?
a.
Global warming can lead to an increased number of earthquakes, which change the Earth’s surface.
b.
Global warming can lead to glaciers melting, causing flooding to areas and the decrease of glacial land masses.
c.
Global warming leads to a decrease in water levels of coastal wetlands.
d.
Global warming cannot lead to changes to the Earth’s surface.
Please select the best answer from the choices provided
A

Answer:
A
Explanation:
But global warming will have additional, far-reaching effects on the planet. Warming modifies rainfall patterns, amplifies coastal erosion, lengthens the growing season in some regions, melts ice caps and glaciers, and alters the ranges of some infectious diseases.
Answer:
I think it is B since Global warming can lead to glaciers melting and cause flooding since the water will get warmer resulting in the ocean rising, which causes flooding

A tank containing water up to a depth of 650 mm is stationary. Find the force exerted by fluid of specific gravity 0.55 on the side of tank, width of tank is 1.5m. Ρ water = 1000 kg/m³:
Answer:
3415.91 N
Explanation:
We know pressure, P at depth, h is P = ρgh where ρ = density of fluid = specific gravity × density of water = 0.55 × 1000 kg/m³ = 550 kg/m³, g = acceleration due to gravity = 9.8 m/s² and h = depth of water = 650 mm = 0.650 m
So, P = ρgh
= 550 kg/m³ × 9.8 m/s² × 0.650 m
= 3503.5 N/m²
Now pressure P = F/A where F = force on the side of tank and A = area of side of tank = depth of water × width of tank = 0.650 m × 1.5 m = 0.975 m²
So, F = PA
= 3503.5 N/m² × 0.975 m²
= 3415.913 N
≅ 3415.91 N
