Answer:
X-linked is a trait where a gene is located on the X chromosome. Humans and other mammals have two sex chromosomes, the X and the Y. In an X-linked or sex linked disease, it is usually males that are affected because they have a single copy of the X chromosome that carries the mutation.
what is the momentum of a bicycle with a mass of 18 kg traveling at 20 m/s?
Answer:360 kg m/s
Explanation:Momentum refers to an object's quantity of motion.
Formula for Momentum: p=mv
p = refers to the momentum
m = refers to the object's mass (this is represented by the unit kg or kilogram)
v = this refers to the object's velocity (this is represented by the unit m/s or meter per second)
So, given that the bike has a mass of 18 kg and is traveling at 20 m/s, then you can already get the momentum by multiplying both of these values.
p = the bike's momentum (what is being asked here)
m = 18 kg
v = 20 m/s
Thus, p = 18kg × 20 m/s = 360 kg m/s
The bike's momentum is 360 kg m/s.

A gas at 8.4 atm has a volume of 1.9 L. What volume would the gas have at 8.3 atm?
Answer:
the final volume of the gas is 1.923 L.
Explanation:
Given;
initial pressure, P₁ = 8.4 atm
initial volume of the gas, V₁ = 1.9 L
final pressure of the gas, P₂ = 8.3 atm
The final volume of the gas is calculated by applying Boyle's law as follows;
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
V₂ = (8.4 x 1.9) / 8.3
V₂ = 1.923 L
Therefore, the final volume of the gas is 1.923 L.
which of the following correctly describes the hierarchy of genetic material within a cell
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.

A coin is dropped off of a building landing on its side. It hits with a pressure of 400/2 It hits with a force of 0.1 Calculate the area of the coin?
Complete Question:
A coin is dropped off of a building landing on its side. It hits with a pressure of 400 N/m². It hits with a force of 0.1N. Calculate the area of the coin?
Answer:
Area = 0.00025 m²
Explanation:
Given the following data;
Pressure = 400N/m²
Force = 0.1N
To find the area of the coin;
Pressure = Force/area
Area = Force/pressure
Substituting into the equation, we have;
Area = 0.1/400
Area = 0.00025 m²
How do you find mass in physics
5.0 kg, with a bullet of mass 0.1 kg. The target was mounted on
low-friction wheels and as the bullet struck the target, the target with
bullet embedded bullet sped off with a velocity of 6.0 ms.
Calculate the velocity of the bullet just before it hit the stationary
target.
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.
What is momentum ?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.

Why is it important that a finger be wet
before it is touched to a hot clothes iron?
Why is it important that your finger be wet if you intend to touch it briefly to a hot clothes iron to test its temperature. If your finger is wet, some of the heat transmitted to your finger will be given to the water which has a high specific heat capacity and also a larger latent heat of vaporization.

D. Sunlight reflecting from a white chalk line on a sidewalk
Ocean waves hitting a concrete barrier that reduces their energy, scenario is the best example of matter absorbing energy from a wave.
Common examples of absorption of wave energy: waves hitting the beach usually give most of their energy to the sand. sunlight landing on a face is mostly absorbed, warming the skin. sound waves hitting thick curtains give up their energy and the sound is muffled.

When we say the energy in a system remains "constant" what we really
mean is...
1 point
the total amount of energy goes up
the total amount of energy remains the same
the total amount of energy goes down
the speed remains the same
of the following is NOT a form of energy?
The total amount of energy remains the same.
Kinetic energy increases as:
A. Mass increases and velocity decreases.
B. Mass decreases and velocity increases.
C. Both mass and velocity increase.
D. Both mass and velocity decrease.
Kinetic energy formula is: 1/2 mv^2
M = mass
V = Velocity
So as kinetic energy increases, mass increases and velocity increases because mass and velocity are directly proportional to each other.
