Answer:
The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases. The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.

Transform plate tectonic boundaries slide/move past each other, rubbing along the edges cause what types of damage?
Question 3 options:
tornadoes, flooding, destruction
hurricanes, flooding, wave surge
earthquakes, tsunami, landslides
blizzards, freezing conditions, snow drifts
Transform plate tectonic boundaries slide/move past each other, rubbing along the edges causing earthquakes, tsunami, landslides
What is earthquake?An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
The answer is c is because when tectonic plates are rubbing against each other that’s how an earthquake is formed.
another reason the answer is C is because when the tectonic plates are moving together it can cause the land to slide.
the last reason the answer is C is because when the tectonic plates in the ocean move it can cause a tsunami.
Hence transform plate tectonic boundaries slide/move past each other, rubbing along the edges causing earthquakes, tsunami, landslides

At high elevations or high latitudes, some of the water that falls on land does not immediately soak in , run off, evaporate or transpire. where is the water being temporarily stored?
Answer:
The water is stored in ice sheets and as snow
Explanation:
Temperature reduces with an increase in altitudes. The standard laps rate is 6.5°C per 1,000 m gained in elevation
At very high elevations, therefore, the air is usually very cold such that when an elevation of 4,500 meters is reached at the equator, it is possible to observe snowfall and the water remain temporarily stored on the surface of the mountain as ice and snow
According to Newton's first law of motion when will an object at rest begin to move
Answer:
When acted upon by a force.
Explanation:

Explain why, in terms of forces, there is a risk of head injury when diving from this height. Suggest why the high divers would choose to enter the water feet first.
Answer:
Due to lower risk of injury or damage.
Explanation:
The high divers would choose to enter the water from the feet first because there is low risk of injury. The brain is the most important part of the body which very sensitive to any small injury. Small injury to brain leads to big problems in life. High divers can reach speeds of nearly 60 mph and enters about 28m into the water in about three seconds which can damage the head region if comes in contact with the ground so this is the reason the high divers avoid of entering in the water through their heads and choose entering through their feet.

A magnifying glass has a converging lens of focal length of 13.8 cm. At what distance from a nickel should you hold this lens to get an Image with a magnification of +2.37?
cm
Answer:
19.6 cm.
Explanation:
From the question given above, the following data were obtained:
Focal length (f) = 13.8 cm
Magnification (M) = +2.37
Object distance (u) =.?
Next, we shall determine the image distance. This can be obtained as follow:
Magnification (M) = +2.37
Object distance (u) = u
Image distance (v) =?
M = v / u
2.37 = v / u
Cross multiply
v = 2.37 × u
v = 2.37u
Finally, we shall determine the object distance. This can be obtained as follow:
Focal length (f) = 13.8 cm
Image distance (v) = 2.37u
Object distance (u) =.?
1/v + 1/u = 1/f
vu / v + u = f
2.37u × u / 2.37u + u = 13.8
2.37u² / 3.37u = 13.8
Cross multiply
2.37u² = 3.37u × 13.8
2.37u² = 46.506u
Divide both side by u
2.37u² / u = 46.506u / u
2.37u = 46.506
Divide both side by 2.37
u = 46.506 / 2.37
u = 19.6 cm
Thus, the lens should be held at a distance of 19.6 cm.
Explain how radioactive decay works for measuring the absolute age of ancient objects.
Answer: Radioactive decay is the breakdown of a material into stable isotopes which are used for determining the age of the ancient material.
Explanation:
The radioactive decay is a natural process in which an ancient or old material whether in the form of rock, object or fossil break down into elements. Carbon 14 is an unstable isotope which decays to produce stable elements, the dating procedure uses these stable elements and the rate of decay of the isotopes to determine the age of absolute ancient of the objects but exact age cannot be determined just an approximation can be accepted.

Help please will give b to the best one!
Answer:
Because the two genes depend on each other, it is possible for someone to actually be a carrier of a dominant trait like brown eyes. And if two blue eyed parents are carriers, then they can have a brown eyed child. Genetics is much bkj

) A 1.0kW kettle contains 500g of boiling waterCalculate the time needed to evaporate all the water
in the kettle (specific latent heat of vaporization2.26 MJ kg-1
Answer:
t = 1130 s = 18.83 min
Explanation:
First, we will calculate the energy required to evaporate 500 g of water:
[tex]E = mL[/tex]
where,
E = Energy Required for evaporation of water =?
m = mass of water = 500 g = 0.5 kg
L = Latent heat of vaporization of water = 2.26 MJ/kg = 2260 KJ/kg
Therefore,
[tex]E = (0.5\ kg)(2260\ KJ/kg)\\E = 1130\ KJ[/tex]
Now, we will calculate the time required:
[tex]P = \frac{W}{t}\\\\t = \frac{W}{P}[/tex]
where,
t = time = ?
P = Power of kettle = 1 KW
Therefore,
[tex]t = \frac{1130\ KJ}{1 KW}\\\\[/tex]
t = 1130 s = 18.83 min

Explanation:
Fig. 2.1 shows a hammer being used to drive a nail into a piece of wood.
hammer head
-nail
wood
Fig. 2.1
The mass of the hammer head is 0.15 kg.
The speed of the hammer head when it hits the nail is 8.0m/s.
The time for which the hammer head is in contact with the nail is 0.0015s.
The hammer head stops after hitting the nail.
(a) Calculate the change in momentum of the hammer head.
Answer:
ΔP = - 1.2 Ns
Explanation:
The change in momentum of the hammer head can be given as follows:
[tex]\Delta P = P_f - P_i\\[/tex]
where,
ΔP = Change in Momentum = ?
Pf = Final Momentum
Pi - Initial Momentum
Therefore,
[tex]\Delta P = mv_f - mv_i\\\Delta P = m(v_f - v_i)[/tex]
where,
m = mass of hammer head = 0.15 kg
vf = final speed of hammer = 0 m/s
vi = initial speed of hammer = 8 m/s
Therefore,
[tex]\Delta P = (0.15\ kg)(0\ m/s-8\ m/s)[/tex]
ΔP = - 1.2 Ns

The behaviour of such incident light on just this pages adequately exemplifies the phenomena called Diffraction. A further explanation is below.
DiffractionThe broadening out of waveforms when they transit through such an apertures anywhere around obstructions generally referred to as diffraction.
It happens whenever the aperture as well as obstruction seems of the equivalent order of magnitude as that of the transmitted beam's wavelength.
