during the time of Moses'
One possible explanation for plagues and the parting of the water is the Santorini volcano eruption and tsunami that occurred sometime possibly coincident with the exodus.

According to tsunami experts, the massive volcanic eruption on the Greek island of Santorini around 1600 BCE could have generated a giant tidal wave or tsunami that struck the Nile Delta, parting of the sea, triggered the ten plagues during the time of Moses' escape from Egypt. Tsunamis are often preceded by the water withdrawing from the shore. A mega-tsunami caused by Santorini's volcano would siphon billions of gallons of water - not just from the shore but from connecting rivers and lakes - creating dry land for as long as two hours. This would give Moses and the Israelites enough time to cross, although maybe not 3 million of them. Heavier chariots may well have been bogged down in the mud. Evidence is based on findings along the rock beddings of shorelines in Africa and Egypt.

This part of the question concerns the graph of the function
f (x) = 1/3 (x − 2)^2 − 3.

(i) Explain how the parabola that is the graph of f can be obtained from the graph of y = x^2 by using appropriate translations and scalings.

(ii) Using your answer to part (i), or otherwise, write down the
coordinates of the vertex of the parabola.

(iii) Find the x-intercepts and the y-intercept of the parabola.

(iv) What is the image set of the function f ? (You should express your answer in interval notation.)

I know that veins are superficial thus easier to spot is one reason. And the high blood pressure in arteries also can be another reason... but can any one confirm whether my theory that if vaccines are injected into the artery then they will be used up for energy or something as they reach an effector or muscle, but if injected into the vein it will be eventually carried to the heart from where it will be spread to the whole of the body?

Hi. I have THREE questions. I tried them myself, but I'm confused. Please help!

1. If the force of friction on the crate is a steady 70 N, and it is pushed along a 10 m factory floor, how much KE is gained by the crate? (Is the answer 3500 MJ?)

2. A force of 50 N is applied to the end of a lever which is moved a certain distance. If the other end of the lever moves one third as far, how much force can it exert? (I don't even know how to start this one)

3. Consider an ideal pulley system. If you pull one end of the rope down with 50 N a distance of 1 meter, how high will you lift a 200 N load? (I don't know what to do here either!)

Please explain/give examples if necessary. The answers don't have to be long, but enough to understand the concepts. :)

Thank You!
