In the rainy season, the Amazon river flows fast and runs deep. In one location, the river is 23 m deep and the water moves at a speed of 4 m/s toward the east. The river is near the equator, where the earth’s 50 μT magnetic field is parallel to the ground and directed north. The water in the river, like the water in all rivers, carries sediments and salts. The water thus carries charged ions and is somewhat conductive.

its a 5.5 n

glad that

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .

a sonic boom is a loud boom that breaks the sound barrier

explanation:

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
