Kinetic Energy =  1/2 * mv²

Kinetic Energy = 14 J,  v = 2.3 m/s ,  m = ?

14  =      1/2 * m* 2.3²

14 = 0.5*m*2.3*2.3

m =  14 / (0.5*2.3*2.3)

m = 5.29 kg.

Mass = 5.29 kg.

Answer: 5.28kg

Explanation:

Kinetic energy is the energy possessed by a body due to virtue of its motion.

Kinetic energy = 1/2MV²

Where M is the mass of the body

V is the velocity

Given Kinetic energy = 14Joules

Velocity = 2.3m/s

Substituting this values into the formula to get mass,

14 = 1/2M(2.3)²

14 = 2.65M

M = 14/2.65

M = 5.28kg

The mass of the bird is 5.28kg

Answer:

  1. It's important that we understand how the climate is changing, so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures
  2. As the cold front passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning.

A change in the gene pool of a population due to chance is _____.
Mrac [35]
<span>The correct answer should be a genetic drift. Mutations usually occur over a relatively short period of time and usually start with a single unit that transfers the mutation when they procreate. Genetic drifts separate entire populations and in time create new species that cannot procreate with the original species from whence they came.</span>
