Which procedure allow you to determine the volume of an irregularly shaped object

1 answer:

6 0

One solution to this problem is measuring water displacement.

If you put the irregularly shaped object in water, then measure the volume of the displaced water, you will have the volume of the irregular object.

What is the Genetic Modification Process?<br><br> Brainlyist for the best answer

Dovator [93]

Answer:

Production of GMOs is a multistage process which can be summarized as follows:

1. identification of the gene interest;

2. isolation of the gene of interest;

3. amplifying the gene to produce many copies;

4. associating the gene with an appropriate promoter and poly A sequence and insertion into plasmids;

5. multiplying the plasmid in bacteria and recovering the cloned construct for injection;

6. transference of the construct into the recipient tissue, usually fertilized eggs;

7. integration of gene into recipient genome;

8. expression of gene in recipient genome; and

9. inheritance of gene through further generations.

Which of the following best describes how galaxies exist in the universe?

anzhelika [568]

I think the correct answer from the choices listed above is option D. Galaxies exist in the universe as they form clusters that are light-years away from other clusters. Other choices are really far away from the truth. Hope this answers the question. Have a nice day.

You attach a 2.90 kg mass to a horizontal spring that is fixed at one end. You pull the mass until the spring is stretched by 0.

Murljashka [212]

Answer:

Explanation:

The spring is stretched by .5 m and then released that means its amplitude of oscillation A is 0.5 m .

A = 0.5 m

After the release at one extreme point , the mass comes to rest again at another extreme point after half the time period ie

T / 2 = .3 s

T = 0.6 s

Angular velocity

ω = $\frac{2\times \pi}{T}$

ω = $\frac{2\times \pi}{0.6}$

ω = 10.45

Maximum velocity = ω A

ω and A are angular velocity and amplitude of oscillation.

Maximum velocity = 10.45 x .5

= 5.23 m /s

Calculate V1 and V2 ( V = voltage )

Kitty [74]

FORMULA:

V = IR, where V = P.D; I = Current; R = Resistance.

ANSWER:

Total equivalent resistance for circuit:

R(eq) = R1 + R2 [It is in series]

330Ω + 470Ω
800Ω

Now, Current passing through whole circuit:

I = V/R

16/800
1/50 ampere

We know that, In series combination current passing through whole circuit is same.

So, V¹ = IR¹

V¹ = 1/50 × 330

V¹ = 6.6 volt

And V² = IR²

V² = 1/50 × 470

V² = 9.4 volt

Two charged spheres on a frictionless horizontal surface are attached to opposite ends of a string & are in static equilibri

deff fn [24]

Answer:

the red sphere has a charge of 9.899 10⁻⁶ C and

the green sphere 0.101 10⁻⁶ C

Explanation:

For this exercise we will use coulomb's law

F = k q₁ q₂ / r²

where they indicate the value of the force F = 2.5 N, the distance between them r = 0.06 m

they also indicate the value of the total load

q₁ + q₂ = 10 10⁻⁶ C

we substitute the values

2.5 = 9 10⁹ q₁ q₂ / 0.06²

2.5 0.06 2/9 10⁹ = q₁ q₂

1 10⁻¹² = q₁ q₂

10 10⁻⁶= q₁ + q₂

we have two equations with two i unknowns, so the system can be solved.

q₁ = 1 10⁻¹² / q₂

we substitute in the other equation

10 10⁻⁶ = 10⁻¹² / q₂ + q₂

let's solve the equation

10 10⁻⁶ q₂ = 10⁻¹² + q₂²

q₂² - 10⁻⁵ q₂ + 10⁻¹² = 0

q₂ = [10⁻⁵ ± √(10⁻¹⁰ - 4 10⁻¹²)] / 2

q₂ = [10⁻⁵ + - 0.9798 10⁻⁵] / 2 = 10⁻⁵ (1 + - 0.9798) / 2

q₂ = 0.9899 10⁻⁵ C

q₂ = 0.0101 10⁻⁵ C

let's find the charge of the other sphere

q₂ = 0.9899 10⁻⁵ C

q₁ = 10⁻⁵ - q₂

q₁ = 10⁻⁵ - 0.9899 10⁻⁵

q₁ = 0.0101 10⁻⁵ C

therefore the red sphere has a charge of 9.899 10⁻⁶ C and

the green sphere 0.101 10⁻⁶ C
