Answer:
R = 715.4 N
L = 166.6 N
Explanation:
ASSUME the painter is standing right of center
Let L be the left rope tension
Let R be the right rope tension
Sum moments about the left end to zero. Assume CCW moment is positive
R[5] - 20(9.8)[5/2] - 70(9.8)[5/2 + 2] = 0
R = 715.4 N
Sum moments about the right end to zero
20(9.8)[5/2] + 70(9.8)[5/2 - 2] - L[5] = 0
L = 166.6 N
We can verify by summing vertical forces
116.6 + 715.4 - (70 + 20)(9.8) ?=? 0
0 = 0 checks
If the assumption about which side of center the paint stood is incorrect, the only difference would be the values of L and R would be swapped.
Answer:
Geothermal
Explanation:
Geothermal is obtained from the heat from the ground which makes it friendly
The answer is period. This is the date range for which you ask the system to return the events depending on the search keys, and keywords you have entered.
C. T,B,U,D,C, and S. D is a tempting answer but it's actually the gluons that transmit the strong force.
B sunlight, because the sun has energy and that gives the soil energy and the plant take that energy and is able to grow.
