Answer:

Why sex cells only need half the number of chromosomes compared to other cells in the body?  As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.

1 . The higher the frequency, the closer the waves are together and the LOWER the energy carried by the waves will be. FALSE

2. The greater the force that produces a wave, the greater the amplitude of the wave and the greater the energy carried by the wave. TRUE

3. In a transverse wave the higher the wave, the LOWER the amplitude FALSE

4.Wavelength is a measure of the distance from the crest on one wave to the crest on the very next wave, TRUE
5. Speed is a measure of the distance a wave travels in an amount of time TRUE

6. As a wave enters a different medium, the wave’s speed changes. Waves travel at different speeds in different media TRUE

7. The highest point of a transverse wave is the crest and the lowest point is called a trough. TRUE

A wave is a disturbance in a medium that carries energy and  as well as momentum. Energy can be transferred in the form of wave in the medium. there are two types of wave,

longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave as shown in the fig.1. Sound wave is a longitudinal wave.

Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave as shown in the fig.2. Light wave is a longitudinal wave.

1. E = hυ where υ is a frequency which shows direct relation between Energy E and frequency υ. Hence it is false.

2. True

3. In a transverse wave the higher the crest in the wave, the higher the amplitude. FALSE

Answer:

306 m/s

Explanation:

Law of conservation of momentum

m1v1 + m2v2 = (m1+m2)vf

m1 is the bullet's mass so it is 0.1 kg

v1 is what we're trying to solve

m2 is the target's mass so it is 5.0 kg

v2 is the targets velocity, and since it was stationary, its velocity is zero

vf is the velocity after the target is struck by the bullet, so it is 6.0 m/s

plugging in, we get

(0.1 kg)(v1) + (5.0 kg)(0 m/s) = (0.1 kg + 5.0 kg)(6.0 m/s)

(0.1)(v1) + 0 = 30.6

(0.1)(v1) = 30.6

v1 = 306 m/s

The initial velocity of the bullet can be determined from the total momentum of the system. The velocity of the bullet was 306 m/s.

Momentum of a body is the product of its mass and velocity. For a collision, the momentum before and after collision will be the same for the colliding system.

Let m1 and m2 be the masses and u be the initial velocity and v is the final velocity.

then,  m1 u1  + m2 u2 = m1 v1  + m2 v2.

Given m1 = 5 kg

m2 =  0.1 kg

The velocity of the combined mass v = 6 m/s.

The momentum of the target is zero since it was stationary.

(0.1 × u1) = (0.1 + 5)6 m/s

(0.1 × u1) = 30.6 m/s

then u1 = 30.6/0.1 = 306 m/s

Therefore, the velocity of the bullet before hitting was 306 m/s.

Answer:

Object's final momentum = 16.7 kg-m/s

Explanation:

Given that,

Impulse, J = 12.2 kg-m/s

Initial momentum, [tex]P_i=4.5\ kg-m/s[/tex]

We need to find the object's final momentum. We know that the impulse is equal to the change in momentum. So,

Impulse = change in momentum

[tex]J=P_f-P_i\\\\P_f=J+P_i\\\\P_f=12.2+4.5\\\\P_f=16.7\ kg-m/s[/tex]

So, the object's final momentum is 16.7 kg-m/s.

Given:

We know the relation,

→ [tex]Impulse = Change \ in \ momentum[/tex]

or,

→ [tex]J = P_f-P_i[/tex]

then,

→ [tex]P_f = J+P_i[/tex]

By substituting the values,

        [tex]= 12.2+4.5[/tex]

        [tex]= 16.7 \ kg-m/s[/tex]

Thus the above answer is right.

The standard equations of the parabolas are listed below:

In this question we have four case of parabolas with vertical axes of reference, whose standard formula is:

[tex]y - k = \frac{1}{4\cdot p}\cdot (x-h)^{2}[/tex]     (1)

Where:

Please notice that p < 0 when the directrix is above the focus, otherwise p < 0. The vertex is the midpoint of line segment between the directrix and the focus.

Now we proceed to derive the standard equations of the parabola:

1) Vertex:

(h, k) = 0.5 · (- 6, 4) + 0.5 · (- 6, - 3)

(h, k) = (- 6, 0.5)

Least distance:

p = - 3.5

y + 6 = - (1/14) · (x + 6)²

2) Vertex:

(h, k) = 0.5 · (0, - 4) + 0.5 · (0, - 5)

(h, k) = (0, - 4.5)

Least distance:

p = 0.5

y = (1/2) · (x + 4.5)²

3) Vertex:

(h, k) = 0.5 · (2, 3) + 0.5 · (2, 7)

(h, k) = (2, 5)

Least distance:

p = 2

y - 5 = - (1/8) · (x - 2)²

4) Vertex:

(h, k) = 0.5 · (- 2, - 6) + 0.5 · (- 2, - 4)

(h, k) = (- 2, - 5)

Least distance:

p = 1

y + 5 = (1/4) · (x + 2)²

The standard form of the given exponential function is 120000.

By putting the number as a base and the number of repetitions as a little number to its upper right, a representation of repeated multiplications of the same number is known as an exponential form.

It is simpler to write repeated multiplication using base and exponents in the exponential form.

The equation f(x) = aˣ, in which the input variable x appears as an exponent and a as the base, describes an exponential function.

So, the given exponential function is,

1.2 x 10⁵

Here, 10 is the base and 5 is the exponent.

10⁵ = 100000

Therefore, the standard form of the given equation is,

1.2 x 100000 = 120000
