A fertilised egg (zygote) has a diameter of 0.01 cm. At birth the average baby measures 50 cm in length. Calculate the change in order of magnitude of length from fertilisation to birth.

does anyone know the answer??​

Answers

Answer 1

Differences in size are often described as differences in the order of magnitude. That's the difference calculated in factors of 10.

At the time of fertilization-

0.01cm = 1/100 = [tex]10^{-2}[/tex]

At the time of birth-

50cm = 5 ×  [tex]10^{1}[/tex]

Meaning there is 3 order of magnitude between the egg(zygote) (0.01cm) and child after the birth ( 50cm ).

Notice that when dividing numbers in standard form, we subtract the powers.

When comparing orders of magnitude, actual distances can be approximated. It’s the relative difference that is important.

Hence, the change in the order of magnitude of length from fertilization to birth of a child is 3 ( three )

A bicyclist accelerates at a constant rate from a standstill to 15 km/hr in 72 sec. a) how fast is the bicyclist traveling after 55 sec? b) how far has the bicyclist traveled after 72 sec?

Answers

A cyclist who accelerates steadily from a stop to 15 km/hr in 72 seconds would reach 4.167 meters per second after 55 seconds.

What is Velocity?

The total displacement covered by any object per unit of time is known as velocity.

As given in the problem a bicyclist accelerates at a constant rate from a standstill to 15 km/hr in 72 sec.

15 kilometers / hour = 15×1000 /3600

                                 =4.167 meters / seconds

v = u + at

4.167 = 0 +a*72

a =4.167/72

a = 0.05787 meters /second²

Speed after 55 seconds = 0.05787*55

                                                                         =3.18285 meters/ seconds

Distance after 72 seconds,

s = ut + 0.5at²

  =0 + 0.5× 0.05787×72²

You start from rest and ski down a hill with an acceleration of 2 m/sec2. Find your speed
at the following times:
a. 2 seconds
b. 10 seconds

Answers

a. Your speed after 2 seconds is 4 m/s.

b. your speed after 10 seconds is 20 m/s.

a. How to find your speed after 2 seconds

To find the speed after 2 seconds, we use the equation of motion v = u + at where

v = speed after 2 seconds, u = initial speed, a = acceleration and t = time

Given that You start from rest and ski down a hill with an acceleration of 2 m/sec².

u = 0 m/s (since you start from rest)a = 2 m/s² andt = 2 s

So, substituting the values of the variables into the equation for the speed, v, we have

v = u + at

v = 0 m/s + 2 m/s² × 2 s

v = 0 m/s + 4 m/s

v = 4 m/s

So, your speed after 2 seconds is 4 m/s.

b. How to find your speed after 10 seconds

To find the speed after 10 seconds, we use the equation of motion v = u + at where

v = speed after 10 seconds, u = initial speed, a = acceleration and t = time

Given that You start from rest and ski down a hill with an acceleration of 2 m/sec².

u = 0 m/s (since you start from rest)a = 2 m/s² andt = 10 s

So, substituting the values of the variables into the equation for the speed, v, we have

v = u + at

v = 0 m/s + 2 m/s² × 10 s

v = 0 m/s + 20 m/s

v = 20 m/s

So, your speed after 10 seconds is 20 m/s.

Triangle has a base that is decreasing at a rate of 11cm/s with the height being held constant. what is the rate of change of the area of the triangle if the height is 7cm?

Answers

The rate of change of the area of the triangle if the height is 7cm is 38.5 cm/s

What is Rate of change?

A rate is anything that can be measured over time. Common rates include velocity (which is the rate of distance traveled), power (rate of work being done), etc. All these have one thing in common which is that they are all divided by the amount of time it took to obtain a certain measurement.

Let the base of the triangle be b,

the height of the triangle = h

and the area of the triangle = A

Area of a triangle, A is = bh/2

Rate of change of the area, A is :

dA/dt = d(1/2(bh))/dt = 1/2 (db/dt)h + 1/2(bdh/dt)

At constant height, dh/dt = 0

that is

dA/dt = 1/2(db/dt)h

It is given that :

db/dt = 11 cm/s

h = 7cm

dA/dt = (11x7)/2  = 38.5 cm/s

Answers

The capacitance of capacitor is 6.44 μF.

We need to know about the capacitance of the air-filled capacitor to solve this problem. The capacitance of the air-filled capacitor depends on the charge and voltage. It can be written as

C = Q/V

where C is capacitance, Q is charge and V is voltage.

Capacitance also can be calculated by the area and distance between the capacitor plate

C = εo . A / d

where εo is vacuum permittivity (8.85 x 10¯¹² F/m), A is the area of the plate and d is distance.

From the question above, we know that

A = 0.8 m²

d = 1.1 x 10¯⁶ m

By substituting the given parameters, we can calculate the capacitance

C = εo . A / d

C = 8.85 x 10¯¹² . 0.8 / 1.1 x 10¯⁶

The amplitude of a sound wave is measured in terms of its maximum gauge pressure. by what factor does the amplitude of a sound wave increase if the sound intensity level goes up by 40.0 db?

Answers

If the sound intensity goes up by 40 db, the amplitude of wave as measured gets increases by a factor of 100.

Calculation

The sound level in decibels can be formulates as

[tex]\beta[/tex] = (10dB) log (I/Io)

Here Io = 10⁻¹²W/m² is specified as the reference intensity

If we assume β₁ as initial sound intensity and β₂ as final sound intensity. Therefore, change in sound intensity can be formulated as

β₁-β₂=40 dB

(10dB) log (I2/Io) - (10dB) log (I1/Io) = 40 dB

(10dB) [log (I2/Io) - log (I1/Io)] = 40dB

log( (I2/Io) / (I1/Io) ) = 40/10 dB

log (I2/I1) = 4dB

I2/I1 = 10^4

The intensity of sound is said as directly proportional to the amplitude of wave squared.

Therefore,

I ∝ A²

I1/I2 = (A1/A2)^2

A2/A1 = [tex]\sqrt{I2/I1}[/tex]

A2/A1 = 100

Therefore, the amplitude of wave increases by a factor of 100.

What exactly is sound amplitude?

A sound wave’s amplitude measures the height of the wave. When a sound is made, the maximum displacement of the medium’s vibrating particles from their mean position determines the amplitude of the sound wave.

What is the km of the enzyme for the substrate a? b) what is the value of v0 when [a] = 43?

Answers

The km of the enzyme for the substrate a is determined as 5000mM, and the value of V0 would be calculated as 0.682nM/minute as per the calculations done.

Why are Km values high or low?

The relationship between KM and the enzyme’s affinity for its substrate is inverse.

Low enzyme substrate affinity is correlated with high levels of KM (it takes more substrate to get to Vmax). An enzyme with a low KM value has a strong substrate affinity.

What is Vmax, and why is it important?

Vmax is the reaction’s maximum rate at the specified enzyme concentration.

The reaction’s speed increases when the concentration of the substrate rises, but after a while, when the enzyme becomes saturated with the substrate, the reaction speed does not continue to rise.

Calculation

As seen after 10000mM concentration of substrate velocity of enzyme becomes constant attain maximum velocity i.e., Vmax

Therefore, we have Km = Vmax/2

= 10000/2 = 5000mM

How does the amount of potential energy change if a hill is taller.

Answers

Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy.

What happens to the pressure of an ideal gas inside a container if the temperature increases from 25 oc to 100 oc but the volume and amount of gas remains constant? (0 oc = 273 k).

Answers

By ideal gas approximation, the pressure will rise until 1.25 times greater than the initial pressure.

We need to know about the ideal gas theory to solve this problem. The ideal gas is assumed that there is no interaction between particles in a gas. It can be determined by the equation

P . V = n . R . T

where P is pressure, V is volume, n is the number of moles gas, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.

From the question above, we know that

T1 = 25 ⁰C = 298 K

T2 = 100 ⁰C = 373 K

Assume that P1 = P

When the initial and final temperature is the same, we can use the ratio of pressure and temperature as

P1 / T1 = P2 / T2

P / 298 = P2 / 373

P2 = 1.25 P

Hence, the pressure will rise until 1.25 times greater than the initial pressure.
