Answer:
can you please tell me what it means
Explanation:
then I'll answer it
<span>The formulas are,
Impulse = mv-mu ....... (1)
v^2 = u^2 + 2as .......... (2)
We know that,
u=0
a=acceleration=gravity = 9.80665 m/s^2 = 9.81 m/s^2
s=19.6
sub (2) we get,
v^2 = 0+ 2*9.81*19.6
v^2 = 2*9.81*19.6
v^2 = 384.552
v = 19.6099
v = 19.61 m/s
Sub v=19.61 m/s in (1) we get,
Impulse = mv - mu
we know that u=0; v= 19.61 m/s; m= 3.00 kg
Impulse = 3(19.61) - 3(0)
Impulse = 58.83-0
Impulse = 58.83 Ns.
Therefore the gravitational force exerted by the stone is 58.83 Ns.</span>
Answer:
Sometimes
Explanation:
Sometimes meaning in occasions. If it is a "vampire star" not likely because they also cause they also make novas happen by sucking the gas from another star.
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,
