All BUT ONE statement provides evidence supporting plate tectonics, through data collected at the sites of sea floor spreading. That is... paleomagnetic reversals in specific areas of the sea floor.
Paleomagnetism, often known as palaeomagnetism, is indeed the study of magnetic field records found in rocks, silt, and other prehistoric materials. When magnetic minerals occur in rocks, they may record the strength and direction of the magnetic field.
Hence, paleomagnetic reversals in specific areas of the sea floor, Paleomagnetism is related to mid-ocean ridges since it is among the most trustworthy techniques for scientists to make a magnetic history of the evolution of the Earth's magnetic field. New rock is continuously formed at an ocean's bottom rift as a result of seafloor spreading.

The boat moves forward due to A. a forward thrust from the propeller that is greater than the backward force of the water current. B. a forward thrust from the propeller that is equal to the backward force of the water current. C. a backward thrust from the propeller against the water that is greater than the force of gravity. D. a backward thrust from the propeller against the water that is less than the force of gravity.
Answer:
(B). a forward thrust from the propeller that is equal to the backward force of the water current.
Explanation:
A boat generates thrust when the propellers are turned to accelerate water forward. According to Newton's third law, the resulting thrust pushes the boat in the opposite direction (i.e. backward direction) which is equal in magnitude.
So, the boat moves forward due to a forward thrust from the propeller that is equal to the backward force of the water current.
Hence. option (B) is correct.

a 87 kg block is pulled across the table by the horizontal force of 43N with a fictional force of 7.3 opposing the motion calculate the acceleration of the object
Answer:
a = 0.41 [m/s²]
Explanation:
To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
F = force [N]
m = mass = 87 [kg]
a = acceleration [m/s²]
The frictional force will be taken as negative, since it opposes the movement of the block.

An earthquake can produce a seiche in a lake in which the water sloshes back and forth from end to end with remarkably large amplitude and long period. Consider a seiche produced in a farm pond. Suppose the pond is 9.15 m long and assume it has a uniform width and depth. You measure that a pulse produced at one end reaches the other end in 2.50s. (b) What should be the frequency of the ground motion during the earthquake to produce a seiche that is a standing wave with antinodes at each end of the pond and one node at the center?
The frequency of the ground motion is 0.2 Hz
What should be the frequency of the ground motion during the earthquake to produce a seiche that is a standing wave with antinodes at each end of the pond and one node at the center?The frequency of the ground motion f = 1/T where T = period of ground motion.
Now, the pond is 9.15 m long and assume it has a uniform width and depth. You measure that a pulse produced at one end reaches the other end in 2.50s.
Since this is a standing wave with antinodes at each end of the pond and one node at the center, we have that the distance between two antinodes is half the wavelength.
Also, the time between two antinodes is half the period.
So, t = T/2
Now, since a pulse produced at one end reaches the other end in 2.50s, this is the time between both antinodes.
So, the period, T = 2t where t = time between antinodes = 2.50 s
So, T = 2t
= 2 × 2.50 s
= 5.0 s
Since the frequency of the ground motion f = 1/T substituting the value of T into f,we have
f = 1/T
= 1/5.0 s
= 0.2 Hz
So, the frequency of the ground motion is 0.2 Hz

A car starts from rest and accelerates at 4 m/s2 until it reaches 36 m/s. How far did it travel in this time?
The distance of a car that starts from rest and accelerates at 4 m/s² until it reaches 36 m/s is 162m.
How to calculate distance?The distance moved by a body can be calculated using the following formula:
S = ut + ½at²
Where;
S = distanceu = initial velocityt = timea = accelerationHowever, the time taken for the car to complete the acceleration can be calculated as follows:
4 = 36/t
t = 9seconds
S = 0 × t + ½ × 4 × 9²
S = 0 + 162
S = 162m
Therefore, the distance of a car that starts from rest and accelerates at 4 m/s² until it reaches 36 m/s is 162m.

Covalent compounds never conduct electricity as we know that these compounds are formed by the sharing of electrons where free electrons are unavailable for the flow of the electric current.
Therefore the correct answer is option D.
What is a covalent bond?Covalent bonds are formed between two atoms, whether they are similar or different when they share an extra electron.
The transport of electrons produces the ionic bond.
Intermolecular compounds are known to never carry electricity because they are created by shared electrons, which prevents free electrons from being available for the transmission of an electric current.

At extreme position, velocity is zero but acceleration is maximum in SHM.how can you theoretically explain it?
At extreme position, velocity is zero but acceleration is maximum in Simple Harmonic motion because of maximum displacement of pendulum.
Why acceleration is maximum when velocity is zero in SHM?At extreme position, velocity is zero but acceleration is maximum in Simple Harmonic motion because at extreme points the motion of the pendulum is at zero which means that velocity is zero but the pendulum attains maximum displacement. Acceleration is maximum when it gets the extreme position because the displacement is maximum at extreme position. If the velocity of the simple harmonic motion is maximum, the acceleration must be equal to zero and we know that the acceleration is equal to zero only when the particle or object is at initial position.
So we can conclude that at extreme position, velocity is zero but acceleration is maximum in Simple Harmonic motion because of maximum displacement of pendulum.

(a) 258Hz (b) 258Hz (c) 262Hz (d) 266 Hz (e) 267 Hz
The supplied tuning fork has a frequency of 262Hz.
A recurring event's frequency is measured by how many times it occurs in a unit of time. To emphasize distinctions with spatial and angular frequencies, respectively, it is also sometimes referred to as ordinary frequency or temporal frequency.
Additionally, it is claimed that when it is played on a mandolin, four beats can be heard every second.
Together, the beats produced by a vibrating mandolin string and tuning fork are referred to as beat frequencies.
Frequency of beat= Frequency of tuning fork + Frequency of mandolin string
Given that a tuning fork's frequency is 262 Hz
String frequency equals 4 beats per second (4Hz).

Explain cylindrical symmetry?A surface or solid of revolution exhibits circular symmetry around an axis in three dimensions. This property is also known as cylindrical symmetry or axial symmetry.
Apply Ampere's law to the circle in the image with the number 1 on it. The magnetic field inside the tube must be zero because the current has a cylindrical symmetry about its central axis, which causes the line integral to reduce to the magnetic field's strength times the path's circumference.
However, this is equal to zero because there is no current flowing along this path. On the other hand, if the conductor's current is the current flowing through channel 2, the line integral will not equal zero, indicating that there is a magnetic field outside the tube.

Calculate the force between two objects that have masses of 70 kilograms and 2,000 Kilograms separated by a distance of 1m
Answer:
The gravitational force between two objects = F = 9.3 x 10⁻⁶ N
Explanation:
Given
m₁ = 70 kg
m₂ = 2000 kg
distance r = 1 m
Thus, the gravitational force between two objects = F = Gm₁m₂ / r²
as
Gravitation constant = G = 6.67430×10⁻¹¹ N⋅m²/kg²
Thus, putting the values
F = Gm₁m₂ / r²
= (6.67430×10⁻¹¹ × 70 × 2000) / 1²
= 9.3 x 10⁻⁶ N
Thus, the gravitational force between two objects = F = 9.3 x 10⁻⁶ N
two skateboarders of mass 50 kg and 60 kg push each other with force 70N.what is the acceleration of each skaters
Answer:
0 m/s²
Explanation:
Since each skater pushes the other with a force of 70 N, according to Newton's third law, there is an equal reaction and thus the other pushes back with a force of 70 N in the other direction, so we have forces of +70N and -70 N respectively. So, the net force on each skateboarder is F = + 70 N + (-70 N) = + 70 N - 70 N = 0 N.
Since force, F = ma where a = acceleration and m = mass,
a = F/m.
So, since for each skater, F = 0N,
a = 0 N/m
= 0 m/s²
So, the acceleration of each skater is 0 m/s²
