010) Identify the true statement. Group of answer choices The height of waves is determined by wind strength and fetch. Wave base is the lowest sea surface elevation attained during the passage of a wave. Waves have no effect on the seafloor near the shoreline. Waves speed up as they enter shallower water.'
Answers
Answer:
The height of the wave is determined by the wind strength and fetch.
Explanation:
The height of the wave is determined by the wind strength and fetch.
The more the strength and the more the fetch size the more will be the height of the wave.
Remember as the wave approaches the coast its wavelength decreases and the wave height increases, whereas when the wave goes away from the coast its wavelength increases and height decreases.

What do you mean by gravitational force with SI unit.
Answers
Answer:
The SI unit system defines 1N of force as the absolute unit of force necessary to provide a mass of 1kg with an acceleration of 1m/s2. Whereas the gravitational unit force is defined as the force experienced by a body of unit mass, that is 1kg, by the gravitation due to Earth. The unit of this force is Kgf
If Earth's gravity pulls an object, causing it to accelerate to the ground, what
must be true about Earth?
A. It accelerates just as quickly in the direction away from the object.
B. It is being pulled toward the object by the object's gravity.
C. It accelerates just as quickly in the direction of the object.
D. It is being pushed away from the object by that same force.
Answers
Ans
It is being pulled toward the object by the objects gravity
Gravity:-
Sir Eizak Newton Founded the gravity.Gravity is a force between any object and earth by which they pull each other .The Acceleration due to gravity is represented by g =9.8m/s^21. explain the procedure undertaken if you have to measure the density of the contents of a milk carton. 2. two objects have the same mass. How about the density of the two objects?
Answers
To calculate the density of a substance, its mass and volume has to be determined. So that:
i. For the milk in the carton, its mass and volume should be known.
ii. For the two objects given in the question, their individual masses and volumes have to be determined.
Density of a substance (ρ) is the rate of the mass (m) of the substance to its volume (V). It is measure in kg/[tex]m^{3}[/tex].
i.e ρ = [tex]\frac{m}{V}[/tex]
The density of a substance can be determined once the mass and its volume have been accurately measured.
1. How to measure the density of the contents of a milk carton.
a. Determine the mass of the milk carton with its content.
b. Determine the mass of the milk carton when empty.
c. Subtract the mass of the milk carton when empty from the mass of the carton with its content. This will give the mass of the milk in the carton.
d. Using a beaker, measure the volume of the milk.
e. Divide the mass of the milk by its volume to determine its density.
2. How to measure the densities of two objects of equal mass.
a. Fill an Eureka's can or a beaker with sprout with water to its brim.
b. Slowly drop the mass into the beaker with water so as to collect the volume of the liquid displaced into another beaker.
c. The volume of the liquid displaced is the volume of the mass.
d. Divide the mass of the object by its volume to determine its density.
NB: These procedures are observed to determine the densities of the two object individually.
