Answer:34.3 N and 15.7 N
Explanation:
= force on the left end of the rod
= force on the right end of the rod
M = mass of Halloween decoration = 3 kg
= weight of the Halloween decoration = Mg = 3 x 9.8 = 29.4 N
m = mass of rod = 2.1 kg
= weight of the rod = mg = 2.1 x 9.8 = 20.6 N
From the force diagram, using equilibrium of torque about A
(AB) + (AC) = (AD)
(29.4) (21) + (20.6) (57) = (114)
= 15.7 N
Using equilibrium of force along the vertical direction
+ = +
15.7 + = 29.4 + 20.6
= 34.3 N

Answer:
i = 2
Step-by-step explanation:
The outside factor multiplies each term in parentheses.
5(2i +4) -i = 38
10i +20 -i = 38 . . . . eliminate parentheses
9i +20 = 38 . . . . . . collect terms
9i = 18 . . . . . . . . . . subtract 20
i = 2 . . . . . . . . . . . . divide by 9

water in cylinder = 1.179π in³
<h3>Further explanation</h3>
Volume is a derivative quantity derived from the length
The unit of volume can be expressed in liters or milliliters or cubic meters
The volume of the cylinder
V = πr².h
the volume of ball
V= 4/3πr³
volume of cylinder
volume of the ball
water in the cylinder
V cylinder - V ball
