A cord is wrapped onto a cylindrical reel mounted on a fixed frictionless horizontal
axle. When does the reel have a greater magnitude of
angular acceleration?
1. When the cord is pulled down with
a constant force of 50 N.
2. When an object of weight 50 N is
hung from the cord and released.
3. The angular accelerations in parts
(a) and (b) are equal.
4. It is impossible to determine.​

20335+282=20617

step-by-step explanation:

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
