Because the two vertices have the same x-coordinate, the side is a vertical line. It starts vertically from -18 to 18
the length = 18 - (-18)
the length = 18 + 18
the length = 36
The length of the side is 36 unit
1. Answer;
Force = 98.1 Newtons
Explanation;
-On the hanging mass the net force is
Fnet = Mh*g - T = Mh*a where Mh is the mass = 10kg, g = 9.81m/s², and T the tension in the string. Its acceleration is a ( same as g)
Thus; Force = 10 kg × 9.81 m/s²
= 98.1 Newtons.
2. Answer;
a = 4.905 m/s²
Solution;
-We know that that T = Ms*a, but Fnet = Mh*g - T = Mh*a
Substituting; T with Ms*a
Mh*g - Ms*a = Mh*a
Mh*a + Ms*a = Mh*g
a = Mh*g/(Mh + Ms)
= 10.0kg*9.81 m/s²/(10kg + 10kg)
= 4.905 m/s²
Answer:
Options B, D and E
Step-by-step explanation:
From the picture attached,
AB and CE are the parallel lines and three lines AD, AC and BE are intersecting these parallel lines.
m∠A = m∠C = 90°
Therefore, AC is perpendicular to the lines AB, CD and CE.
Options B, D and E are the correct options.
