Answer:

micro evolution

Explanation:

Changes within a gene pool occurring from generation to generation is called micro evolution. Allele frequencies in a population may change due to gene flow, genetic drift, natural selection and mutation. These are referred to as the four fundamental forces of evolution.

A 10000 kg rocket blasts off vertically from the launch pad with a constant upward of 2.25 m/s2 and feels no appreciable air res

Sloan [31]

Answer:

The maximum height that the rocket reaches is 645.5 m.

Explanation:

Given that,

Mass = 10000 kg

Acceleration = 2.25 m/s²

Distance = 525 m

We need to calculate the velocity

Using equation of motion

$v^2=u^2+2as$

Put the value in the equation

$v^2=0+2\time2.25\times525$

$v=\sqrt{2\times2.25\times525}$

$v=48.60\ m/s$

We need to calculate the maximum height with initial velocity

Using equation of motion

$v^2=u^2-2gh$

$h=\dfrac{v^2-u^2}{-2g}$

Put the value in the equation

$h=\dfrac{0-(48.60)^2}{-2\times9.8}$

$h=120.50\ m$

The total height reached by the rocket is

$h'=s+h$

$h'=525+120.50$

$h'=645.5\ m$

Hence, The maximum height that the rocket reaches is 645.5 m.

A girl lifts a 160-N load to a height of 1 min 0.5 s. How much power is used to lift the load?

Aleonysh [2.5K]

Answer: 320 W

Explanation:

P = W/t

W = F * d

F = 160 N

d = 1 m

t = 0.5 s

W = 160 * 1

W = 160 J

P = 160 J / 0.5 s

P = 320 W

Why doesn't every planet have a moon?

GalinKa [24]

Answer:

Up first are Mercury and Venus. Neither of them has a moon. Because Mercury is so close to the Sun and its gravity, it wouldn't be able to hold on to its own moon. Any moon would most likely crash into Mercury or maybe go into orbit around the Sun and eventually get pulled into it.
