Answer:
i'd say 1kg-----5m-----5kg but im not to sure
Explanation:
B. Some elements found in nature exist as molecules.
Answer:
Explanation:
From the question we are told that:
Mass
Initial Velocity
Final Velocity
Generally the equation for Work-done is mathematically given by
W=\triangle K.E
Therefore
There's not enough information in the question to answer it.
-- If the batteries are in series, then
more batteries ==> brighter bulbs.
-- If the batteries are in parallel, then the number of batteries
has no effect on the brightness of the bulbs.
These two predictions apply equally well whether the bulbs
are in series or in parallel.
IRON
<em>The vast majority of the Earth's supply of iron is found in the core and the mantle. The solid inner core is almost entirely composed of iron, while the liquid outer core is an alloy of iron and nickel, with small amounts of lighter elements. The mantle is composed of iron-magnesium silicates, and the crust is composed of roughly 5 percent iron. All together, iron makes up an estimated 35 percent of the Earth's mass.</em>
Oxygen
<em>Oxygen, the second most abundant element on Earth, is found mainly in the crust. Although oxygen is most often thought of as an atmospheric gas, it is also one of the primary components of the silicate minerals that make up the vast majority of the Earth's crust. Oxygen itself makes up approximately 46.6 percent of the crust and 30 percent of the mass of the entire Earth.</em>
