A.helium has no valency
B.lithium has 1
C.nitrogen has either 5 or 3 because it bonds outer orbital
D.magnesium has 2
The answer would be C. 80%
Put 160 over 200 and find the GCF
160/200÷40=4/5=80%
Answer:
kinetic
Explanation:
A vehicle takes good chemical energy stored in the bonds of hydrocarbons (gasoline) and converts it into movement (kinetic energy), air vibration (noise), and heat (wasted energy in the summer), some electricty for the radio, spark plugs, fans, and cell phone charger. But the aswer here is kinetic, since the word "moving" is specified.
Answer:
The vertical distance traveled is 3.18 m.
Explanation:
In order to find the vertical distance traveled by a body in free fall motion, starting from rest to a velocity of 7.9 m/s. For this purpose, we use Newton's third equation of motion,
2as = Vf² - Vi²
where,
a = g = 9.8 m/s²
s = vertical distance = Δy = ?
Vf = final velocity = 7.9 m/s
Vi = initial velocity = 0 m/s
Therefore,
2(9.8 m/s²)Δy = (7.9 m/s)² - (0 m/s)²
Δy = (7.9 m/s)²/(2)(9.8 m/s²)
<u>Δy = 3.18 m</u>
