Answer:

25

Explanation:

By Using Pythagoras Theorem,

h^2=p^2+b^2

or, x^2=(24)^2+7^2

or, x^2=576+49

or, x^2=625

or, x=√625

•°• x=25

How does visible Light travel through outer space?

Dima020 [189]

By the electromagnetic "vibrations" that make up light. Said EM vibrations are an electric field and a magnetic field at right angles to each other and to the direction of propagation/travel. Light travels by the same "mechanism" that X rays travel, radio waves travel and anything else in the vast electromagnetic spectrum. Probably how I'm able to type these words on a computer key board and have them transmitted "Wi Fi" like, to you, the hapless recipient. You're a Cheetah ??? That means you can run like the wind ????

EJ is taking his little sister, Ebony, on her first carousel ride. His mass is 75.0 kg, and her mass is 10.0 kg. They ride the s

You have to find interia using I=mr^2.

m=75+10

radius = 11

Then you have to substitute in first formula above to find the angular speed.

14020=(75+10)x v x 11

v= 14020/ (85x11) = 15m/s

To find linear speed, use V=wr.

Equation: V = 11*1.363 = 15m/s = 33.6mi/hr

Hope this helps! :)

14.0 m uniform ladder weighing 490 N rests against a frictionless wall. The ladder makes a 65.0°-angle with the horizontal. (a)

Mkey [24]

Answer:

The horizontal reaction force is 230.3 N.

Explanation:

Given that,

Length l= 14.0 m

Weight of ladder F = 490 N

Angle = 65°

Weight of firefighter F'= 850 N

Height l'= 4.10 m

Suppose horizontal force magnitude N direction vertical force magnitude N direction

We need to calculate the horizontal reaction force

Horizontal reaction force = normal reaction from wall

Vertical reaction force = weight of ladder +weight of man

$F=490+850$

$F=1340\ N$

We need to calculate the moment about bottom is zero

$N\times l\sin\theta=F\times\dfrac{l}{2}\cos\theta+F'\times l'\cos\theta$

Put the value in the equation

$N\times14\sin(65)=490\times7\cos(65)+850\times4.10\cos(65)$

$N=\dfrac{490\times7\cot(65)+850\times4.10\cot(65)}{14}$

$N=230.3\ N$

Hence, The horizontal reaction force is 230.3 N.
