The Traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. Variant copies of a gene are called alleles, and an individuals genotype is the sum of all the alleles inherited from the parents.

A bird carrying a fish (5kg) drops it from 107 meters in the air how fast does the fish hit the ground

notka56 [123]

Answer:

The velocity of the fish hitting the ground is , v = 45.795 m/s

Explanation:

Given data,

The mass of the fish, m = 5 kg

The height of the bird from the surface, h = 107 m

Using the III equation of motion,

v² = u² + 2gs

<em> v = √(u² + 2gs)</em>

Substituting the values,

v = √(0² + 2 x 9.8 x 107)

= 45.795 m/s

Hence, the velocity of the fish hitting the ground is, v = 45.795 m/s

How much conventional current must you run in a solenoid with radius = 0.05 m and length = 0.39 m to produce a magnetic field in

Ugo [173]

Answer:

Explanation:

radius of the solenoid, r = 0.05 m

length of the solenoid, l = 0.39 m

Magnetic field of the solenoid, B = 2 x 10^-5 T

Number of turns, N = 200

The magnetic field of the solenoid is given by

$B=\mu _{0}ni$

where, i be the current and n be the number of turns per unit length

n = N / l = 200 / 0.39 = 512.8

$2\times 10^{-5}=4 \times 3.14\times 10^{-7}\times 512.8\times i$

i = 0.031 A
