Answer: Tension =1520 N

Step-by-step explanation: Given:

Mass of elevator=190kg

Acceleration of elevator=1.8m/s^2

Acceleration due to gravity =9.8m/s^2

Weight acting downward=W=mg

W= 190Kg×9.8m/s^2

W=1862N

Upward force is Tension

EFy=may

+ is up

- is down

T - 1862=190(1.8)

T=1862-342

T= 1520N

Answer:

The tension in the cable that lifts the elevator = 2204 N

Step-by-step explanation:

Tension in cable acting upward  = T

Weight of lift acting downward = W = mg

                                                   = (190)(9.8) = 1862 N

Total force acting in vertical direction = ∑Fy = T - mg

Force applied to move elevator upward = F = ma

                                                                   =(190)(1.8) =342 N

Total force acting in vertical direction = Force applied to move elevator upward

T - mg = ma

T = mg + ma

T= 1862 +342

T = 2204 N

Why is f(x)=0 the only odd and even function?
kupik [55]
F is odd if and only f f(-x) = -f(x) so f(x) = 0 works because 0 = 0 always.

f is even if and only if f(-x) = f(x) so f(x) = 0 works because there's no x term so nothing changes. 0 = 0.

PART1:

First Combination:
Pizza ($7) + Chicken Strips ($6) + Biscuits ($3) + Grapes ($4) = $20

Second Combination:
Dog Food ($13) + Bread ($3) + Crackers ($2) + Broccoli ($2) = $20

Third Combination:
Shampoo ($4) + Tissues ($3) + Pizza ($7) + Eggs ($3) + Biscuits ($3) = $20


PART 2:

First Combination:
$7.20 + $5.70 + $2.90 + $3.70 = $19.60
No, I wouldn’t have gone over the limit

Second Combination:
$13.40 + $3.50 + $2.00 + $1.90 = $20.80
Yes, I would have gone over the limit

Third Combination:
$3.50 + $2.60 + $7.20 + $2.50 + $2.90 = $18.70
No, I wouldn’t have gone over the limit

Hope this helps!!
