After the shock of seeing animals falling from the sky and silence, comes what you may have already imagined; that is, we would die from lack of oxygen - and in about 3 minutes. The worst thing is that not even patients connected to respirators in hospitals or divers equipped with cylinders could survive, since there is a need for pressure to be able to breathe.
Answer:
bo sure but I think its c or a
1,000 grams = 1 kilogram
20 grams = 0.02 kilogram
Kinetic energy = (1/2) (mass) x (speed)²
(1/2) (0.02) x (15)² =
(0.01) x (225) = 2.25 joules
Answer:
v = 2.89 m / s
Explanation:
This is a kinematics exercise, the centripetal acceleration is
a = v² / r
where a is the acceleration, v is the velocity and r the radius
let's clear
v = √a r
let's calculate
v = √ (27 0.31)
v = 2.89 m / s
this is the speed of the drum which is constant
Answer:3 is sublimation
