Answer:
True Explosion in antarctic sea ice levels may cause another ice age.
Explanation:
True
Using computer models, the studies show that a rise in sea ice may significantly change the ocean's circulation, ultimately resulting in a reversed greenhouse effect as ocean carbon dioxide rises and air levels decrease.
Some scientists at the University of Chicago said their analysis shows how the rise of Antarctic sea ice in cold climate could cause a cascade of shifts that could lead to turning the global climate towards glacial periods,
A) average acceleration = final velocity - initial velocity / time
= 7700 - 0 / 11
= 700ms^-2
B) force = mass x acceleration
= (3.05 x 105) x 700
= 320.25 x 700
= 224,175N
Answer:
An unknown number of identical light bulbs are connected to a 15 V battery in parallel. The current through the battery is 2 A. If the light bulbs are connected to the battery in series, the current through the battery is 5 mA. How many bulbs are there?
3 bulbs are there from the analogy given above
Explanation:
Sound is a mechanical wave <span>that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. If a sound wave is moving from left to right through air, then particles of air will be displaced both rightward and leftward as the energy of the sound wave passes through it. The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport. This is what characterizes sound waves in air as longitudinal waves.</span><span>

Answer:
Options (A), (B), (D), and (E).
Explanation:
Density is a physical property that describes the relationship between mass and volume. This property shows whether an object will float or it will get sink. The density of substances changes with the changing temperature, as both are inversely proportional to each other.
Mathematically, density can be written as,
Density = 
ρ = 
, Where, ρ = density, m = mass, v = volume
Thus, the correct answers are options (A), (B), (D), and (E).
