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.

Answers

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.

Answers

The global winds and moisture belts indicate that large amounts of rainfall occur at the Earth's equator because air is rising and converging.

What is  Earth's equator?

The equator is a large circle that circles the planet Earth, lying in a plane perpendicular to the axis of the planet and being equally spaced from all four geographic poles.

Rainfall in equatorial regions averages 4000mm per year. Every other raining produces about 22 days of precipitation in a month. The equatorial regions have higher temperatures because solar radiation produces a lot of heat there.

The cold air filters down into the lower levels of the atmosphere because the hot air is less dense here than the cold air. The tropical regions become warmer as a result. In the tropical rain belt, the tropical climate predominates.

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.

Answers

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

Explain how radioactive decay works for measuring the absolute age of ancient objects.

Answers

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.

) 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

Answers

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
