Two brown eyed parents (Bb) have a baby. What is the chance their baby will have blue eyes? (B - brown; b - blue)

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ The correct answer choice is 25%. If you cross Bb and Bb in a punnett square, you get BB, Bb, Bb, bb. All of these are dominant besides bb (which is blue eyes and recessive) so 75% is brown eyes and 25% is blue eyes.

A force is applied to a particle along its direction of motion. At what speed is the magnitude of force required to produce a gi
krek1111 [17]

Answer:

Explanation:

The detailed steps are as shown below

  • Recalling from F = ma
  • a = F/m
  • but magnitude of force F = √ [ 1 - v²/c²]

but acceleration twice as great as the force required to produce the same acceleration;

  • 2m = m / √[ 1 - v²/c²]
  • 2 = 1 / √ [ 1 - v²/c²]
  • square both sides ;

4 = 1 / [ 1 - v²/c²]

1/4 = 1 - v²/c²

v²/c² = 3/4

v/c = √ [3/4]

v = 0.87c

but speed of light c = 3 x 10^8m/s

v = speed of the particle =  0.87( 3 x 10^8m/s)

v = 2.61m/s

Compare how people are affected by an Air Quality Index of 140 with how they would be affected by an Air Quality Index of 170.
AfilCa [17]

Answer:

The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality.
