Answer: D- Each chromosome in a cell is made up of two chromatids, which are each made up of molecules of DNA
Explanation:
A macromolecule is a large molecule that is made of many smaller units. Chromosomes are macromolecules that contain all of the genetic information in a cell. Chromosomes are each made of two smaller units called chromatids. Chromatids are each made up of molecules of DNA. Therefore, the correct description of the hierarchy of genetic material in a cell is that each chromosome in a cell is made up of two chromatids, which are each made up of molecules of DNA. The structures become more and more microscopic as one moves down the hierarchy.
When a guitar string is plucked, sound waves, which are mechanical waves, transmit sound to your ears. What is the primary medium through which the sound waves travel?
The primary medium through which the sound waves travel is
Air.
What is a Wave?A wave is defined as a disturbance that travels through a
medium which transports energy from one place to another in
the process.
In a guitar, the vibration of the string sets the surrounding air
molecules into vibrational motion which thereby produces
sound heard.

Q2.
The information plate on a hairdrier is shown.
230 V
VSO Ha
800 W
(a) What is the power rating of the hairdrier?
Answer:
800W
Explanation:
Given the following data;
Voltage = 230 V
Model = VSO Ha
Power = 800 W
Power is calculated by the multiplication of voltage and current flowing through an electric circuit.
Mathematically, power is given by the formula;
Power = current * voltage
The S.I unit for power is Watts and it is a measure of the energy consumption of an electronic device.

An initially motionless test car is accelerated to 115 km/h in 8.58 s before striking a simulated deer. The car is in contact with the faux fawn for 0.815 s, after which the car is measured to be traveling at 60.0 km/h. What is the magnitude of the acceleration of the care before the collision? What is the magnitude of the average acceleration of the car during the collision?
Answer:
a) a = 3.72 m / s², b) a = -18.75 m / s²
Explanation:
a) Let's use kinematics to find the acceleration before the collision
v = v₀ + at
as part of rest the v₀ = 0
a = v / t
Let's reduce the magnitudes to the SI system
v = 115 km / h (1000 m / 1km) (1h / 3600s)
v = 31.94 m / s
v₂ = 60 km / h = 16.66 m / s
l
et's calculate
a = 31.94 / 8.58
a = 3.72 m / s²
b) For the operational average during the collision let's use the relationship between momentum and momentum
I = Δp
F Δt = m v_f - m v₀
F = [tex]\frac{m ( v_f - v_o)}{t}[/tex]
F = m [16.66 - 31.94] / 0.815
F = m (-18.75)
Having the force let's use Newton's second law
F = m a
-18.75 m = m a
a = -18.75 m / s²
A police car is moving east at 20m/s towards a driver who is moving west at 25m/s. The police car emits a frequency of 900Hz. What frequency is detected by the driver? The speed of sound at the time of this occurrence was 343m/s.
Answer:
f = 2445 Hz
Explanation:
i did the quiz
The frequency that the driver (observer) detects is equal to 1008 Hz
Given the following data:
Observer velocity = 25.0 m/sFrequency of sound = 900 HzSource velocity = 20.0 m/s Speed of sound = 343 m/sTo calculate the frequency that the driver (observer) detects, we would apply Doppler's effect of sound waves:
Mathematically, Doppler's effect of sound waves is given by the formula:
[tex]F_o = \frac{V \;+ \;V_o}{V\; - \;V_s} F[/tex]
Where:
V is the speed of a sound wave.F is the actual frequency of sound.[tex]V_o[/tex] is the observer velocity.[tex]V_s[/tex] is the source velocity.[tex]F_o[/tex] is the observer frequency.Substituting the given parameters into the formula, we have;
[tex]F_o = \frac{343 \;+ \;20}{343\; - \;20} \times 900\\\\F_o = \frac{363}{323} \times 900\\\\F_o = 1.12 \times 900\\\\F_o =1008 \;Hz[/tex]
Driver (observer) frequency = 1008 Hz

the candle had 350 J of energy in the chemical store. As it burned, 250 J was transferred by lighting to the surrounding
Answer:
Efficiency = 71%
Explanation:
Given the following data:
Output energy = 250 Joules
Input energy = 350 Joules
To find efficiency;
[tex] Efficiency = \frac {Out-put \; energy}{In-put \; energy} * 100 [/tex]
Substituting into the equation, we have;
[tex] Efficiency = \frac {250}{350} * 100 [/tex]
[tex] Efficiency = 0.7143 * 100 [/tex]
Efficiency = 71.43 ≈ 71%
Therefore, the efficiency of the candle is 71 percent.

True or False. The fulcrum of a first class lever is between the output force and an input force.
Answer:
True
Explanation:
A first-class lever is a lever in which the fulcrum is located between the input effort and the output load. In operation, a force is applied (by pulling or pushing) to a section of the bar, which causes the lever to swing about the fulcrum, overcoming the resistance force on the opposite side
