two sides of a triangle have the following measures . Find The range of possible measures for the tird side

1 answer:

3 0

To find the third side you would use Pythagorean theorem which is a²+b²=c².

A and B being the 2 legs and C being the hypotenuse.

Example: ( sorry for the really odd not really a triangle, triangle...)
| \
6| \ ? 6²+9²=C²
|_______ 36+81=C²
9 117=C²
√117=10.8 (rounded)

if you need to get the leg you just fill in the numbers.

Your computer is an example of which type of energy? Question options: Nuclear Kinetic Light All of the above

xz_007 [3.2K]

Answer: Light

Computer is an example of light energy which is the third option out of the given four choices. 

Explanation:

We know how a computer works it takes in the electrical energy and does a lot of mathematical mechanical work and for giving answers. It uses a screen on which light blinks in pattern such that it represents letters or mathematical numbers or expressions.

Hence by using this statement we can say computer converts electrical energy into light energy.

U-235 undergoes many different fission reactions. For one such reaction, when U-235 is struck with a neutron, Ce-144 and Sr-90 a

Lostsunrise [7]

Explanation:

A nuclear fission reaction is defined as the reaction in which a heavy nucleus splits into small nuclei along with release of energy.

The given reaction is $^{235}_{92}U + ^{1}_{0}n \rightarrow ^{144}_{58}Ce + ^{90}_{38}Sr + x^{1}_{0}n + y^{0}_{-1}\beta$

Now, we balance the mass on both reactant and product side as follows.

235 + 1 = $144 + 90 + (x \times 1) + (y \times 0)$

236 = 234 + x

x = 236 -234

= 2

So, now we balance the charge on both reactant and product side as follows.

92 + 0 = $58 + 38 + (x \times 0) + (y \times -1)$

92 = 96 - y

y = 4

Thus, we can conclude that there are 2 neutrons and 4 beta-particles are produced in the given reaction.

Therefore, reaction equation will be as follows.

$^{235}_{92}U + ^{1}_{0}n \rightarrow ^{144}_{58}Ce + ^{90}_{38}Sr + 2^{1}_{0}n + 4^{0}_{-1}\beta$
