6. How does sea-floor spreading explain why the youngest rocks are found near the mid-Atlantic ridge?
Answer:
With distance from the ridge crest, the sediments and crust get thicker. This also supports the idea that the youngest rocks are on the ridge axis and that the rocks get older with distance away from the ridge (Figure below). Something causes the seafloor to be created at the ridge crest.
Answer: With distance from the ridge crest, the sediments and crust get thicker. This also supports the idea that the youngest rocks are on the ridge axis and that the rocks get older with distance away from the ridge (Figure below). Something causes the seafloor to be created at the ridge crest
Explanation:
New rock is formed near the mid-oceanic ridge as oceanic plates diverge or separate from each other. Hot rocks rising from the asthenosphere melt from decompression as they rise, filling the fault and forming new basaltic oceanic crust. As new crust is added, older crust is pushed away. Therefore, the further away from the mid-oceanic ridge, the older the rocks.
During exercise, the supply of oxygen and __________ to muscles increases. What one word completes the sentence?
Answer:
Glucose
Explanation:
During exercise, muscles need more energy. They get this energy by aerobic respiration, which uses oxygen and glucose to release energy.
Note: If the body fails to supply oxygen to the muscles fast enough, the muscles will produce energy by anaerobic respiration, which is not as effective as aerobic respiration in addition to producing lactic acid.
During exercise, the supply of oxygen and glucose to muscles increases. During exercise, muscles need more energy.
What happens during exercise?They get this energy by high-impact breath, which utilizes oxygen and glucose to deliver energy.
During exercise, your muscles are working diligently. Your breathing and pulse increment, maneuvering more oxygen into the circulation system. As you work out, the oxygen that arrives at your muscles changes over accessible glucose into ATP, furnishing your body with the energy it requires to finish your exercise.

A boat with an initial speed of 5.0 m/s accelerates at a uniform rate of 1.2
m/s2 for 5.0 s. What is the final speed of the boat during this time? (P.4B)
A. 6.0 m
B. 6.2 m
C. 11 m/s
D. 26 m/s
Answer:
v = 11 m/s
Explanation:
Given tha,
Initial speed, u = 5 m/s
Acceleration, a = 1.2 m/s²
Time, t = 5 s
We need to find the final speed of the boat during this time. Let it is v. Using first equation of motion as follows :
v = u +at
Putting all the values, we get :
v = 5 + 1.2(5)
v = 11 m/s
So, the final speed of the boat is 11 m/s. Hence, the correct option is (c).

A repelling force occurs between two charged objects when the charges are of Equal magnitude. Equal magnitude. a Unequal magnitude.b Unequal magnitude. c Like/same signs.d Like/same signs. e Unlike signs. help plz
Answer:
c Like/same signs
Explanation:
A repelling force occurs between two or more charged objects with the charges are of like or same sign.
According to Coulombs law, like charges repel on another, unlike charges attracts on another. If a positive charge comes into the vicinity of another positive charge, there will be repulsion. When oppositely charge species are brought near each other, there is an attraction.Therefore, repulsion occurs when like charges are brought close to each other.

Find the acceleration produced.
Answer:
0.67m/s²
Explanation:
Given parameters:
Mass of toy = 1.2kg
Force applied = 0.8N
Unknown:
Acceleration = ?
Solution:
According to newton's second law of motion;
Force = mass x acceleration
Now,
Acceleration = [tex]\frac{Force}{mass}[/tex]
Acceleration = [tex]\frac{0.8}{1.2}[/tex] = 0.67m/s²
Answer:
Givenforce = 0.8 N
mass = 1.2 kg
To findforce
Formula used[tex] \boxed{force = m.a}[/tex]
solutionAccording to Newton's second law of motion
[tex] \boxed{ \bold \pink {\underline{f =m.a}}} [/tex]
where
f= force
m= mass
a= acceleration
substitute the value in the above formula
0.8 = 1.2 × accleration
accleration= 0.8/1.2
acceleration= 0.66 m/sec²

Answer:
a = 6.87 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
[tex]v_{f} =v_{o} +a*t[/tex]
where:
Vf = final velocity = 37 [m/s]
Vo = initial velocity = 15 [m/s]
a = acceleration [m/s²]
t = time = 3.2 [s]
Note: The positive sign in the above equation means that the velocity is increasing, due to the acceleration.
37 = 15 + a*3.2
3.2*a = 37 - 15
a = 6.87 [m/s²]
A beach ball, moving with a velocity of 2 m/s, rolls off a pier and hits the water 0.5 m from the end of the pier. It strikes the water 0.25 seconds later. How high is the pier above the water? Disregard air resistance. 1.23 m 0.31 m 0.61 m 2.45 m
Answer:
0.31 m
Explanation:
The following data were obtained from the question:
Horizontal distance (s) = 0.5 m
Horizontal velocity (u) = 2 m/s
Time (t) = 0.25 s
Height (h) of the pier =.?
The height of the pier can be obtained as illustrated below:
Time (t) = 0.25 s
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) of the pier =.?
h = ½gt²
h = ½ × 9.8 × 0.25²
h = 4.9 × 0.0625
h = 0.31 m
The, the height of the pier is 0.31 m

Newton's first law states that objects do not change their motion unless acted upon by a net force. What does the word "net" mean in this context?
A A woven net, such as a fishing net or basketball net
B To catch or ensnare
C Remaining or left over after everything has been accounted for
D To cover, such as with mosquito netting
Answer:
Explanation:
C Remaining or left over after everything has been accounted for.
You can have as many forces as you can define as long as there is an opposing force that cancels it out. If there is just 1 more force that cannot be cancelled, then it is a remaining force and it determines what happens to the object.
The rest have to do with something that resembles a fisherman's net.

A 3 kg book is on a shelf 3 m tall. What is its potential energy?
Answer:
88.2J
Explanation:
Given parameters:
Mass of book = 3kg
Height of shelf = 3m
Unknown:
Potential energy = ?
Solution:
The potential energy of a body is the energy due to the position of that body.
It can be mathematically calculated as;
P.E = mgh
m is the mass of the body
g is the acceleration due to gravity = 9.8m/s²
h is the height
Now insert the parameters and solve;
P.E = 3 x 9.8 x 3 = 88.2J

Passengers fall forward when a bus suddenly stops. Using your knowledge of Newton's First Law and Inertia, explain why this phenomenon happens.
Answer:
The people on the bus fall forward because Newton's Law of Inertia states that and object in motion with stay in motion or an object at rest will stay at rest unless acted in by another force. The force of the bus stopping suddenly caused the passengers to fall forward because they were at rest position.

The Dominican Republic has 10.7 million people and a national population growth rate of 1.5 percent. Paraguay
has 6.8 million people and a national population growth rate of 1.5 percent. In how many years will each
country double in size?
47 years
37 years
27 years
57 years
Answer:
The correct answer is - 47 years.
Explanation:
The doubling time of the population growth depends on the rate of population growth. The formula for the calculation of the doubling time is :
time (t) = log(N/N0)/r (time)
here,
N0 (initial population) = The population at time t = 0.
N (future population) = The population at time t.
r (rate) = The rate of population change as a function of t
by the formula
t = log (2/1)/0.015
t = 46.666 years or 47 years approx.
The population of each country will become double in 47 years. hence option (A) is correct.
Given data:
The population of Dominican republic is, n = 10.7 million.
The growth rate of Dominican republic is, p = 1.5 %.
The population of Paraguay is, n' = 6.0 million.
The growth rate of Paraguay is, p' = 1.5 %.
The doubling time of the population growth depends on the rate of population growth. The formula for the calculation of the doubling time is given as,
[tex]t = \dfrac{ln\dfrac{n}{n_{0}}}{p}[/tex]
Here,
[tex]n[/tex] is the final population and [tex]n_{0}[/tex] is the initial population and for doubling the value in future, [tex]n = 2 \times n_{0}[/tex].
Solving as,
[tex]t = \dfrac{ln\dfrac{2\times n_{0}}{n_{0}}}{1.5/100}\\\\t \approx 47 \;\rm years[/tex]
Thus, we can conclude the population of each country will become double in 47 years.

A rocket initially at rest on the ground lifts off vertically with a constant acceleration of 20m/s^2. How long will it take the rocket to reach an altitude of 16km
16 km = 1/2 (20 m/s²) t ²
t ² = (32 km) / (20 m/s²)
t ² = (32,000 m) / (20 m/s²)
t = √(1600 s²)
t = 40 s
