Answer:

43 kg

Explanation:

Force (F) = 162 N

acceleration (a) = 3.8 m/s²

mass (m) = ?

We know

F = m * a

162 = m * 3.8

m = 162 / 3.8

m = 43 kg

It's mass is 43 kg.

The best description of twins with identical DNA is that the twins will be identical physically and behaviorally. Thus, the correct option is C.

Identical twins are also called as the monozygotic twins which result from the fertilization of a single egg by a single sperm, or with the fertilized egg which are then splitting into two individual offspring. Identical twins share the same genomes and are also of the same sex.

Answer:

2900 N

Explanation:

We are given;

Magnetic flux density; B = 3.6 × 10² T

Length of wire; L = 19 m

Current; I = 0.043 A

Formula for force in this regards is;

F = BIL

Where;

B is Magnetic flux density

I is current

L is length

Thus;

F = 3.6 × 10² × 0.043 × 19

F = 2941.2

To 2 significant figures gives;

F = 2900 N

good luck, i hope this helps :)

Answer:

The direction of these oscillations is the difference between longitudinal or transverse waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. In transverse waves, the vibrations are at right angles to the direction of wave travel.

Explanation:

The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

A sound wave is the wave that shows the disturbance patterns that should be lead by the movement of the energy that should be travelled via the medium like air, water, since it should be propagated away from the sound source.

Therefore, The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

Answer: Boat P

Explanation:

Multiple all of them mass times acceleration and which ever one was the greatest was the answer. Which was Boat P 0.2436

The minimum time taken to unwind the rubberband is by boat P.

The highest amount of force to unwind the rubberband is generated by boat P.

The table shows all the mass, acceleration and time of each boat. To unwind the rubber band, the required force can be calculated as given below.

Force = Mass [tex]\times[/tex] Acceleration

For boat N, force is [tex]f_n = 0.125\times 1.6 = 0.2 \;\rm N[/tex]

For boat P, force is [tex]f_p = 0.116\times 2.1 = 0.24 \;\rm N[/tex]

For boat Q, force is [tex]f_q = 0.130\times 1.0 = 0.13 \;\rm N[/tex]

For boat R, force is [tex]f_r = 0.118\times 1.8 = 0.21 \;\rm N[/tex]

Hence we can conclude that the highest amount of force to unwind the rubberband is generated by boat P.

Answer:

[tex]d=7970\ kg/m^3[/tex]

Explanation:

Given that,

The density of iron is 7.97 g/cm³.

We need to find the density in SI unit. The SI unit of density is kg/m³.

We know that,

1 kg = 1000 g

1 m = 100 cm

So,

[tex]7.97\ g/cm^3=7.97 \times \dfrac{(\dfrac{1}{1000})\ kg}{(\dfrac{1}{100}^3)\ m^3}\\\\=7970\ kg/m^3[/tex]

So, the density of the iron is [tex]7970\ kg/m^3[/tex].

Answer: 9 Joules

Explanation:

Kinetic enegry is one half the mass multiplied by the velocity squared

KE = 1/2mv^2

[tex]KE=1/2(2)(3^2)\\KE=3^2\\KE=9J[/tex]

The kinetic energy of the body is 9J

Kinetic energy is the energy possessed by a body due to its motion.

It is claculated by formula,

K.E = [tex]\frac{1}{2}mv^{2}[/tex]

Here,

The mass of the body = 2.0kg

speed = 3.0m/s

So kinetic energy K.E = [tex]\frac{1}{2}mv^{2}[/tex]

K.E = [tex]\frac{1}{2} (2)3^{2}[/tex] = 9J

So the kinetic energy of the body is 9J

All music in the world, is form only two notes and those notes are described below in detailed explanation.

Explanation:

In the chromatic scale, there are basically seven central musical notes, designated A, B, C, D, E, F, and G. They individual express a separate pitch or frequency. For illustration, the "central" A note has a pitch of 450 Hz, and the "common" B note has a pitch of 495 Hz.

Varieties Of Musical Notes You Require To Understand

Semibreve (Whole Note)

Minim (Half Note)

Crotchet (Quarter Note)

All music, listened to in the world, is from only twelve (12) notes.

A music can be defined as the systematic combination of an instrumental sound and human vocals, in order to produce harmonious tunes or sounds.

A note can be defined as a symbol which is used to denote a musical sound with respect to its pitch and duration.

Basically, all the music that are available and listened to in the world are typically produced from only twelve (12) notes.
