Answer: 98 millimeters
Explanation:
Since angle VTY is congruent to angle VTK, segment TY bisects angle VTK. Since Y is on segment VK, between V and K, we can use the Angle Bisector Theorem, which states that
(1)
Since x= VK = VY + YK, we need to obtain VY since YK = 68.
VY is obtained by multiplying the denominator YK on both sides of equation (1). So,
Hence,
x = VK = VY + YK
x = 30 + 68
x = 98 millimeters
(B) 1.00 m
Explanation:
Since the meter stick is traveling with Jill, it will have the same speed as she does so relative to Jill, the meter stick is stationary so its length remains 1.00 m as measured by her.
Answer:
D: Water is polar, so it can form attractions to and pull apart molecules of many types of substances.
Explanation:
Water is an excellent solvent simply because its polar water molecules usually form hydrogen bonds with ions and polar molecules, thereby allowing the ionic and polar covalent compounds to easily disperse easily in water.
Thus, the correct option is; D
Answer:B
Explanation:
Because the Earth's core isn't moving around earth therefore the center of Earth will forever be warm
