Calculate the average net force.

MrRa [10]

Answer:

<h2>given</h2>

mass = 3950 kg

speed= 25m/ sec

time= 10.5 sec

force

<h2>Solution</h2>

<h3>☄️Formula of force </h3>

$\fbox{f = m.a}$

To find the force we need to find the Acceleration first.

accleration= change in Velocity/time

accleration= 25/10.5

accleration= 2.38 m/sec²

put the value of accleration in the formula of force

force = Mass . accleration

force = 3950 x 2.38

<h3>☄️force = 9,401 Newton</h3>

Can two people with brown eyes have a blue eyed baby

Elena L [17]

Answer:

Yes

Explanation:

Each person has two alleles (forms of a gene) for a characteristic. We can represent them using letters.

Dominant trait are written as capitals. If a dominant allele is present in someone's genotype, the dominant trait will show.

The recessive trait only shows if a person has two recessive alleles.

Brown eyes is a dominant trait, and blue eyes is a recessive trait.

B = dominant brown eyes

b = recessive blue eyes

If someone has brown eyes, their genotype can be:

BB

Bb

If someone has blue eyes, their genotype is:

bb

The baby's genotype must be bb because it has blue eyes. The baby gets one allele from each parent.

See the photo for Punnett square. If the parents are both Bb, then they could each give the b allele, resulting in a blue-eyed baby.

Identify the labeled parts in the figure.

Hitman42 [59]

Answer:

I. a, c, f and h

II. e

III. b, d, g and i

IV. i

Explanation:

I. Chemical symbols are simple abbreviations used to represent various elements or compound. They consist entire of alphabet.

For the diagram given above, the labelled parts which represent chemical symbol are: a, c, f and h

II. Coefficients are numbers written before the chemical symbol of elements or compound.

For the diagram given above, the labelled part which represent Coefficient is: e

III. Number of atoms of element present in a compound is simply obtained by taking note of the numbers written as subscript in the chemical formula of the compound.

For the diagram given above, the labelled part which represent the number of atoms of the element are: b, d, g and i

IV. When no number is written as subscript in the formula of the element in the compound, it means the element has just 1 atom in the compound.

For the diagram given above, the labelled part which indicates that only 1 atom of the element is present is: i

A magnetic field has a magnitude of 1.2 \times 10^{-3} T, and an electric field has a magnitude of 4.6 \times 10^{3}N/C. Both fi

Answer: F = 113.4. $10^{-3}$ N

Explanation: Net Force is the total forces acting in an object. In this case, there are two forces acting on the charge: one due to magnetic field (Fm) and another due to electric field (Fe). So, net force is

F = Fe + Fm

Force due to electric field

To determine this force:

Fe = q.E, where q is the charge and E is electric field.

Calculating:

Fe = q.E

Fe = 1.8. $10^{-6}$ .4.6. $10^{3}$

Fe = 8.28. $10^{-3}$ N

Force due to magnetic field: It can only happens when the charge is in movement, so

Fm = q.(v×B), where v represents velocity and B is magnetic field

The cross product indicates that force is perpendicular to the velocity and the field.

Calculating:

Fm = q.v.B.senθ

As θ=90°,

Fm = q.v.B

Fm = 1.8. $10^{-6}$ .3.1. $10^{6}$ .1.2. $10^{-3}$

Fm = 6.696. $10^{-3}$ N

F, Fm and Fe make a triangle. So, using Pythagorean theorem:

F = $\sqrt{Fe^{2} + Fm^{2} }$

F = $\sqrt{(8.28.10^{-3} )^{2} +(6.696.10^{-3} )^{2} }$

F = 113.4. $10^{-3}$ N

The net force acting on the charge is F = 113.4. $10^{-3}$ N
