Explain what it means when scientists say that the offspring of sexual reproduction are genetically diverse.

Physics

Likurg_2 [28]3 years ago

Answer: During sexual reproduction, the genetic material of two individuals is combined to produce genetically-diverse offspring that differ from their parents.  The genetic diversity of sexually-produced offspring is thought to give species a better chance of surviving in an unpredictable or changing environment

A car moving with an intial velocity of 60m/s is brought to rest in 30 seconds calculate the acceleration
gregori [183]

Answer:

a = 2 [m/s^2]

Explanation:

To solve this problem we must use the expressions of kinematics, we must bear in mind that when a body is at rest its velocity is zero.

v_{f} = v_{i} - (a*t)

where:

Vf = final velocity = 0

Vi = initial velocity = 60 [m/s]

a = desacceleration [m/s^2]

t = time = 30 [s]

Note: the negative sign of the above equation means that the car is slowing down, i.e. its speed decreases.

0 = 60 - (a*30)

a = 2 [m/s^2]

A conducting rod moves perpendicularly through a uniform magnetic field. How does the emf change if the magnetic field is increa
Marysya12 [62]

Answer:

c) It increases by a factor of 8

Explanation:

According to Faraday's law (and Lenz' law), the induced EMF is given as the rate of change of magnetic flux.

Mathematically:

V = -dФ/dt

Magnetic flux, Ф, is given as:

Ф = BA

where B  = magnetic field strength and A = Area of object

Hence, induced EMF becomes:

V = -d(BA)/dt  or -BA/t

If the magnetic field is increased by a factor of 4, (B_n = 4B) and the time required for the rod to move is decreased by a factor of 2 (t_n = t/2), the induced EMF becomes:

V_n = -(B_nA)/t_n

V_n = \frac{-4BA}{(t/2)}\\\\V_n = \frac{-8BA}{t} \\\\V_n = 8V\\

The EMF has increased by a factor of 8.

Which has the greater momentum when moving?
Basile [38]
I assume there are choices to this question that you forgot to include. No matter, I could just lay out the concept so that you can understand the gist.

The best way to approach this is to know the definition of momentum. In physics, momentum is always defined in terms of equation. For momentum, it is the product of the mass and velocity. Therefore, any increase of these two parameters would promote greater momentum. The greater the mass paired with the faster the velocity, the greater the momentum.
