F  = ma

12.5 Newtons  =  12.5kg * m  / s^2

12.5 kg m / s^2  =  1.0 kg  *  a        [ divide out kg ]

12.5 m /s^2   =  a

Your second answer is correct.....look at your  first  one, again....

We're glad to have you, CoolStuffYT   !!!

EP's  answer is correct....

See  this, Jenny   :  https://www.answers.com/Q/What_is_the_frequency_of_a_pendulum

First one   

Two of the numbers are > 4

We have 6 total numbers

What's the probability  ???

Second one

We have 3 evens

We hav 6 total numbers

What's the probability  ???

Correct !!!

There are no orange  cars.....so.....what's the probability  ???

a b c d e f g h i j k  l  m  n   o  p  q  r  s t u v w  x y  z

bvrf    

Because of the "a"....shift the  b back  one letter   = a

Because of the d, shift the v back 4 letters  =   r

Because of the e, shift the r back 5 letters  = m

Because of the g, shift the  f back 7 letters = y

" a  r   m  y "

log _1/2  16 -  log ₉  27      

Note that  in exponential form

(1/2)^(-4)  =  1 / (1/2)^4  =  1  /(1/16)   = 16

So....the first expression evaluates to -4

And

9^x  = 27

(3^2)^x  = 3^3

(3)^(2x)  = 3^3      the bases are the same.....solve for the exponents

2x= 3    divide both sides  by  2

x  = 3/2

So.....the second expression evaluates to 3/2

So

-4  - (3/2)   =

-8/2  - 3/2  =

-11/2  = -5.5

Second one

P( no 3 appears on either face)  =   5/6  * 5/6   =  25 / 36
