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

Question 6 You cross a true-breeding red-flowered snapdragon with a true-breeding white-flowered one. All of the FI are pink. Wh
muminat

Answer:

E (Red shows incomplete dominance over white)

Explanation:

This portrays a monohybrid cross involving a single gene coding for flower colour in snapdragon plants. According to the question, a purebreeding red flowered (homozygous) plant is crossed with a purebreeding white flowered (homozygous) plant to produce an all pink flowered offspring. This phenomenon is called INCOMPLETE DOMINANCE.

Mendel, in his experiments, discovered that an allele can mask the expression of another in a heterozygous state. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. However, exceptions like INCOMPLETE DOMINANCE, has occurred in the sense that an allele does not completely mask the expression of its allelic pair, instead an intermediate phenotype, which is a combination/blending of both parental phenotypes is produced.

In this case, the red flowered snapdragon (RR) does not completely cover up the expression of white flower (rr), hence a hybrid/heterozygous offspring is produced that combines the phenotypic characteristics of both parents to form an intermediate flower colour (pink). Hence, it can be said that Red flower is incompletely dominant over white flower or no allele/trait is dominant or recessive to another.
