D. 18.1
K^+H^+G^=180° (sum of int angles of triangle)
K^+30+62=180
K^=88°
GH/sinK=KG/sinH
X/sin88=16/sin62
X*sin62/sin62=16*sin88/sin62
X=18.1
The different versions of an element have different isotopes, like Copper-63 and Carbon-65. The average of these two is not 64, because there are more Carbon-63 in the world than Carbon-65, 69.17% Copper-63 and 30.83% Copper-65, to be exact. By multiplying the atomic mass per unit of each one times their respective abundance in the world turned into a decimal, and adding these two products together, you het the atomic mass overall, which is 63.55
Answer:
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
Explanation:
As we know that average velocity is defined as the ratio of change in position and the time interval of the object
It is given as
so we will have
= displacement
= time interval
the direction is this average velocity is always along the direction of the displacement
so correct answer will be
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
The procedure that makes stars sparkle is the same one that we have outfit for utilization as a weapon: atomic combination.
Stars begin as gigantic districts of gas, for the most part hydrogen. This gas will begin to contract, and it warms up. As it gets, its temperature rises. At the point when the warmth gets sufficiently high, it causes the individual hydrogen iotas to impact and consolidate into helium with the arrival of vitality. This is called fusion.
