When does the edge of the water advance farther inland- when the ocean's floor is a gradual slope or steep slope?
Answer:
The correct answer is when the slope is steep.
Explanation:
The advancement of water inland is dependent on the rate at which water wears off the continental shelf and the coastal plain. The higher the amount of rainfall, and the harshness of the dry spells, the faster the rate of erosion that occurs at the coastal plain.
As the erosion increases, the coastal plain becomes steeper. The steeper the plain, the water flowing erodes the coastal plain at a faster rate. Hence the water advances farther inland faster than where the slope is gentle or gradual.

what causes waves to slow down: change in wave’s wavelength or change in its frequency and y?
Answer:
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes.
how far will an automobile move if 168000 j of work is created by 2000 n of force
Answer:
Distance = 84 meters
Explanation:
Given the following data;
Work done = 168,000 Joules
Force = 2,000 Newton
To find the distance covered by the automobile, we would use the formula;
[tex] Workdone = force * distance [/tex]
Substituting into the formula, we have;
[tex] 168000 = 2000 * distance [/tex]
[tex] Distance = \frac {168000}{2000} [/tex]
Distance = 84 meters
3.- Un barco que tiene el motor averiado es ayudado por dos remolcadores para entrar en el puerto. Cada uno de ellos tira de él con una fuerza de 10000 N y ambas forman un ángulo de 60o. Calcula el módulo de la fuerza neta que actúa sobre el barco.
Answer:
F_total = 10000 N
Explanation:
For this exercise we use that the force is a vector and the best way to do the sum is that since the two tugs pull the boat with the same intensity and angle, the sum of the component of the force perpendicular to the movement becomes zero.
The components parallel to the movement of the tugs is
∑ F = 2 Fcos θ
let's calculate
F_total = 2 10000 cos 60
F_total = 10000 N

A day on a distant planet observed orbiting a nearby star is 21.5 hr. Also, a year on the planet lasts 69.3 Earth days. In other words, for the purposes of unit conversion, there are 24 hr in a day, 60 min in an hour, and 60 s in a minute, as it would for astronomers on Earth observing the planet. Calculate the average angular speed of the planet about its own axis of rotation in radians per second, with the second as measured on Earth. what is the speed of rotation? Calculate the average angular speed of the planet as it travels around its neighboring star, with the second as measured on Earth. what is the speed of orbit?
Answer:
Part A
The angular speed of rotation of the plane is 8.11781 × 10⁻⁵ rad/s
Part B
The angular speed of orbit of the planet is 1.04938 × 10⁻⁶ rad/s
Explanation:
The parameters of the planet are;
The duration of a day on the distant planet = 21.5 hr.
The duration of a year on the distant planet = 69.3 Earth days
Part A
The duration of a day = The time to make one complete revolution of 2·π radians
∴ The average angular speed about its axis, [tex]\omega_{rotation}[/tex] = Angle turned/Time
∴ [tex]\omega_{rotation}[/tex] = 2·π/(21.5 × 60 × 60) s ≈ 8.11781 × 10⁻⁵ rad/s
The average angular speed of the planet about its own axis, [tex]\omega_{rotation}[/tex] = 8.11781 × 10⁻⁵ rad/s
The angular speed of rotation of the plane [tex]\omega_{rotation}[/tex] = 8.11781 × 10⁻⁵ rad/s
Part B
The time it takes the planet to revolve round the neighboring star once = 69.3 Earth days
Therefore, the average angular speed of the planet around its neighboring star, [tex]\omega _{Star}[/tex], is given as follows;
[tex]\omega _{Orbit}[/tex] = 2·π/((69.3 × 24 × 60 × 60) s) = 1.04938 × 10⁻⁶ rad/s
The average angular speed of orbit, [tex]\omega _{Orbit}[/tex] = 1.04938 × 10⁻⁶ rad/s
The angular speed of orbit of the planet, [tex]\omega _{Orbit}[/tex] = 1.04938 × 10⁻⁶ rad/s.

in each of the following divide the second number by the first number and find the quotient:3/4,-3/8
Answer:
[tex]\dfrac{-1}{2}[/tex]
Explanation:
We need to divide the second number by the first number and the numbers are 3/4,-3/8.
First number = 3/4
Second number = -3/8
Dividing the second number by the first number.
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}[/tex]
We know that,
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}=\dfrac{-3}{8}\times \dfrac{4}{3}\\\\=\dfrac{-1}{2}[/tex]
So, the answer is (-1/2)
A light ray bounces off a fish in your aquarium. It travels
through the water, into the glass side of the aquarium, and
then into air. As the light from the glass hits the air, the index of
refraction for air is much
than the index of refraction
for glass which causes the light to bend toward the angle that it
entered the air.
Answer:
Correct
Explanation:
Because the light can't travel as quickly in the water as it does in the air, the light bends around the pencil, causing it to look bent in the water. Basically, the light refraction gives the pencil a slight magnifying effect, which makes the angle appear bigger than it actually is, causing the pencil to look crooked.

5) Apply according to the Law of Universal Gravitation, is there a stronger gravitational force between you and Earth or an elephant and Earth? Why?
Answer:
Elephant and the eath because Fg is determined by Mass of an object.. So elephant has greater mass therefore, it's Fg is higher
According the universal law of gravitation, the gravitational force is directly proportional to the mass of an object. An elephant weighs so much than a man and thus it will experience larger gravitational force from earth.
What is gravitational force?Gravitational force is a resistive force by which an object attracts other objects towards its centre of mass. The force exerted by the object depends on the mass and the force experienced by the other object depends on its mass and distance between the two objects.
According to universal law of gravitation, the gravitational force is directly proportional to the mass of the object and distance from the ground. The expression for the law is written as:
[tex]\rm g = G \frac{M_{1} M_{2}}{r^{2}}[/tex]
Where, G is the universal gravitational constant and M1 and M2 be the masses of two objects which and r be the distance between them. As per this relation gravity decreases with increase in distance and increase with an increase in mass.
Therefore, a massive body such as an elephant will experience greater gravitational force from the earth.

Answer:
Water
Explanation:
A dilution is a solution made by adding more solvent to a more concentrated solution (stock solution), which reduces the concentration of the solute. An example of a dilute solution is tap water, which is mostly water (solvent), with a small amount of dissolved minerals and gasses (solutes).

An Athelice complete :Round of a circular track of diameter 200m in base Distance travelled by athletes And displacement
Answer:
Distance = 1256 m
Displacement = 0
Explanation:
Distance :
Distance may be defined as the actual length between two points along its path.
It is a scalar quantity and its value can be positive or zero.
Displacement :
Displacement is defined as the shortest length between two point , i.e. between the initial point and the final point.
It is a vector quantity and it has values which can be either positive or negative or zero.
From the question, the diameter of the circular track is, r = 200 m
∴ Distance travelled by an athlete is = circumference of the circular track
= 2πr
= 2 x 3.14 x 200
= 1256 m
Displacement = 0 (since the original point coincides with the final point).

A 4 kg mass is moving at 8 m/s collides with a 2 kg mass moving at 5 m/s.
After the collision, both objects stick together, what is the velocity of the
two cars? *
Answer:
V = 7 m/s
Explanation:
Given that,
Mass 1, m₁ = 4 kg
Speed of the object 1, v₁ = 8 m/s
Mass 2, m₂ = 2 kg
Speed of object 2, v₂ = 5 m/s
After the collision, both objects stick together. Let V be the common velocity. Using the conservation of linear momentum to find it.
[tex]m_1v_1+m_2v_2=(m_1+m_2)V\\\\V=\dfrac{m_1v_1+m_2v_2}{m_1+m_2}\\\\V=\dfrac{4(8)+2(5)}{4+2}\\\\V=7\ m/s[/tex]
So, the velocity of two cars is 7 m/s.
