Answer:

All of the genetic information comes from one parent.

Explanation:

The question states that the organism has genes that are identical to the parent's. The egg is a type of Gamete, which means that it needs a sperm in order to produce anything, which would have to come from another parent, but, since the genes are unchanged, it can't be that one. The same logic applies to the 2nd and 4th as well

A tube of mercury with resistivity 9.84 × 10 -7 Ω ∙ m has an electric field inside the column of mercury of magnitude 23 N/C tha

slava [35]

Answer:

The current through the tube is 73.39A.

Explanation:

The relationship between the resistivity $\rho$ , the electric field $E$ , and the current density $J$ is given by

$\rho = \dfrac{E}{J}$

This equation can be solved for $J$ to get:

$J = \dfrac{E}{\rho}$

Since the current is $I = J\cdot A$

$I= J\cdot A = \dfrac{E}{\rho} \cdot A$

Now, for the tube of mercury $\rho = 9.84*10^{-7}\: \Omega \cdot m$ , $E = 23N/C$ , and the area is $A = \pi r^2 = \pi (1.0*10^{-3}m)^2 = 3.14*10^{-6}m^2$ ; therefore,

$I= \dfrac{23N/C}{9.84*10^{-7}\Omega\cdot m } *3.14*10^{-6}m^2$

$\boxed{I = 73.39A.}$

Hence, the current through the mercury tube is 73.39A.

Can a body have two acceleration at a time?

bixtya [17]

Answer:

No.

Explanation:

Acceleration of an object is defined as the rate of change of velocity per unit time. It can be given by :

a = dv/dt

dv is the change in velocity i.e. final velocity-initial velocity

dt is change in time

At a particular time, its change in velocity can be one only. It would imply that a body cannot have two acceleration at a particular time.

1. How would the forces from a header with such a light soccer ball cause a concussion? Draw

melomori [17]

Answer:

soccer when the ball hits an unprepared player in the head. He also gave examples of concussions occurring when players accidentally knock their heads into other players while attempting to head the ball, particularly if they are attempting to flick the ball backwards.

Explanation:

Heading in soccer can increase your risk of concussions. Over time, repeated subconcussive injuries can also accumulate and cause brain damage.

Assuming the same current is running through two separate coils, why is it easier to thrust a magnet into a wire coil with one l

alexira [117]

it is easier to thrust a magnet into a wire coil with one loop than one with four loops Because with four loops it becomes more difficult to push the magnet in.

<h3>What is a magnetic field?</h3>

It is the type of field where the magnetic force is obtained. The magnetic force is obtained it is the field felt around a moving electric charge.

The quantity of turns or loops in a coil directly relates to the intensity of the magnetic field within the coil.

As a result, the magnetic field strength has increased fourfold when there are four loops instead of one, making it more difficult to push the magnet in.

A single-looped wire coil is simpler to insert a magnet into than one with four loops. because inserting the magnet gets more challenging when there are four loops.
