Tsunamis are fast-moving waves often generated by underwater earthquakes. In the deep ocean their amplitude is barely noticable,

but upon reaching shore, they can rise up to the astonishing height of a six-story building. One tsunami, generated off the Aleutian islands in Alaska, had a wavelength of 646 km and traveled a distance of 3630 km in 6.15 h. (a) What was the speed (in m/s) of the wave

Answer:

v =163.95 m/s

Explanation:

Given that,

The wavelength of wave, \lambda=646\ km=646\times 10^3\ m

Distance covered, d=3630\ km=3630\times 10^3\ m

We need to find the speed of the wave. We know that,

speed = distance/time

So,

v=\dfrac{3630\times 10^3\ m}{22140\ s}\\\\=163.95\ m/s

So, the speed of the wave is equal to 163.95 m/s.

More recent findings of children with exceptionally high IQs _
Alenkasestr [34]

Answer:

Explanation:

Researchers and educators differ in how they define gift-

edness. Traditionally, researchers have defined giftedness

as high general intelligence as measured by a high global

IQ score (Hollingwort

Exceptionally intelligent students (hereafter referred to

as gifted students) face a variety of problems in ordinary

classrooms. They often are ostracized as being different

and weird and are labeled as nerds and geeks (Silverman,

1993a, 1993b). In addition, they face the problem of

boredom due to lack of an appropriate level of challenge

(Csikszentmihalyi, Rathunde, & Whalen, 1993; Gross,

1993). Teachers often make little accommodation to the

needs of these children, and many teachers have little

or no special training in how to teach such exceptional

children
