A force of 2.20 N is exerted on a 7,20 g rifle bullet. What is the bullet's acceleration? (Enter your answer in m/s^ 2 )
sweet [91]

Answer:

The answer is 306 m/s^2

Explanation:

F = m*a

We can rearrange this formula to get a = F / m.

The SI unit for mass is kilograms (kg).

The SI unit for acceleration is m/s^2.

There are 1000 grams in a kilogram.

7.20 g = 0.00720 kg

Force (2.20 N) / 0.00720 kg = 305.56 m/s^2

Accounting for Sig Figs, the answer is 306 m/s^2.

Gee, that's one fast bullet.

How can two organisms with a dominant trait for a specific feature produce an organism with a recessive trait for the same featu
Liono4ka [1.6K]

Answer:

If the two organisms are heterozygous for the dominant trait.

Explanation:

For every trait, a diploid organism receives two forms of gene called ALLELE, from each parent. Allele is the variant form of a gene.

According to Mendel's law of dominance, for a particular trait, an allele is capable of masking the expression of another allele in a gene. The expressed allele is called the DOMINANT allele while the masked allele is called the RECESSIVE allele. Due to this, an organism can express a dominant trait even in a combined or heterozygous state i.e. different alleles.

When the two heterozygous organisms mate or are crossed, they undergo meiosis and their alleles are separated into GAMETES according to Mendel's law of segregation. For example; an organism with genotype (genetic make-up) Aa will produce gametes with A and a alleles.

Note that, a recessive trait can only be expressed in a homozygous state i.e. same allele. Hence, the two heterozygous organisms will produce gametes containing the recessive allele, which will likely combine to produce a recessive phenotype or trait.
