Physics

GREYUIT [131]3 years ago

But the fact is that an accelerating object is an object that is changing it’s velocity.. for this reason , it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing .

When viewed in yellow light, an object that reflects all the colors of light will appear_____.
Bas_tet [7]

Answer:

Yellow.

Explanation:

An object that reflects all the incidents colors of light will surely reflect off the color yellow, and when the reflected ray hits our eyes, we will perceive the object as yellow. The object that reflects off all colors appears to us as white. So if you want to make sure, then just shine yellow light on a white fabric and see what happens!

What you will observe of course is a yellow fabric. Similarly, if you shine red light onto the fabric, it will appear red, and so on for all colors.

Suppose you are asked to find 91,321,972×0.007004. Doing a quick estimate by rounding the numbers in scientific notation, what v
slamgirl [31]

Answer:

Product, P=9.1321972\times 10^7\times 7.004\times 10^{-3}

P = 639619.091888

Explanation:

In this case, we need to find the product of two numbers. These are as follows :

N_1=91321972=9.13\times 10^7

N_2=0.007004=7.004\times 10^{-3}

On doing calculation, we get the product of two numbers as :

P=N_1\times N_2

P=9.1321972\times 10^7\times 7.004\times 10^{-3}

P = 639619.091888

In scientific notation the product of two number is given by :

P=63\times 10^4

Hence, this is the required solution.
