A child riding a bicycle at 15 m/s accelerates at 3. 0 m/s/s for 4. 0 s. What is the child's speed at the end of this 4. 0 s int
mamaluj [8]

Answer:

The final speed of bicycle would be <u>27 m/s</u>².

Step-by-step explanation:

<u>Given</u> :

  • \small\red\bull Initial velocity (u) = 15 m/s
  • \small\red\bull Acceleration (a) = 3.0 m/s²
  • \small\red\bull Time = 4 seconds

<u>To</u><u> </u><u>Find</u> :

  • \small\red\bull Final velocity (v)

<u>Using</u><u> </u><u>Formula</u> :

\longrightarrow{\pmb{\sf{v = u + at}}}

  • \small\blue\star v = final velocity
  • \small\blue\star u = initial velocity
  • \small\blue\star a = acceleration
  • \small\blue\star t = time taken

<u>Solution</u> :

Substituting the values in the formula to find the final velocity :

\longrightarrow{\sf{v = u + at}}

\longrightarrow{\sf{v = 15 + (3.0 \times 4)}}

\longrightarrow{\sf{v = 15 + (3 \times 4)}}

\longrightarrow{\sf{v = 15 +(12)}}

\longrightarrow{\sf{v = 15 +12}}

\longrightarrow{\sf{v = 27 \:  {m/s}^{2}}}

\star{\underline{\boxed{\red{\sf{v = 27 \:  {m/s}^{2}}}}}}

Hence, the final speed of bicycle would be 27 m/s².

A masked allele in the genotype that is only expressed when 2 of the same masked alleles are inherited
Simora [160]

A masked allele in the genotype that is only expressed when 2 of the same masked alleles are inherited is called recessive trait.

<h3>What is a trait?</h3>

A trait can be defined as a distinguishing quality (characteristic) of a living organism. Thus, it refers to the specific features and characteristics that are possessed by a living organism.

According to Genetics, traits are essentially divided into two (2) and these include:

  • Dominant traits.
  • Recessive traits.

In conclusion, a recessive trait typically refers to a masked allele in the genotype (h0m0zygous) that is only expressed by a living organism when two (2) of the same masked alleles are inherited.
