According to Darwin's theory of evolution, how does natural selection cause species to evolve over time?

Elena L [17]

As time goes on, members of a population with favorable traits continue to breed while those without these traits eventually die off. For instance, if all of the food in an area was high up in the trees, only members of the species with long necks are able to eat and continue to live and reproduce. Those with shorter necks will not be able to eat and will eventually die off. Over time, the species will evolve to have long necks.

Hope this helps!

A square coil, enclosing an area with sides 3.2 cm long, is wrapped with 2,720 turns of wire. A uniform magnetic field perpendic

marishachu [46]

Answer

$\epsilon = -0.74\ V$

Explanation:

given,

Side of square coil = 3.2 cm

Number of turns = 2720

magnetic field in the coil increases to = 0.45 T

time interval = 1.7 s

average induced voltage in the coil = ?

length = 0.032 m

Area = 0.032² = 0.001024 m²

induced voltage

$\epsilon = -NA \dfrac{dB}{dt}$

$\epsilon = -2720 \times 0.001024 \times \dfrac{0.45}{1.7}$

$\epsilon = -0.74\ V$

The average voltage induced in the coil is equal to $\epsilon = -0.74\ V$
