What percent of offspring will be brown eyed?
25%
50%
75%
100%
Please I need help
Answers
================================================
Explanation:
Uppercase B is the brown eyed gene. It's dominant over the recessive gene lowercase b, which is for blue eyes. Convention has the uppercase letter always dominate over the lowercase recessive gene.
Note the genotypes of the offspring are all Bb. This tells us we have nothing but brown eye offspring. The visual indicator also shows four brown eyes, which backs up each Bb genotype. The phenotype is the observed brown eyes that others can see, while the genotype deals with the gene pairings.
Since four offspring out of four total have brown eyes, this means the percent of brown-eyed offspring is 4/4 = 1.00 = 100%

TRUE OR FALSE Light can travel through materials that you cannot see through, like wood or aluminum foil.
Answers
Answer: TRUE
Explanation:
(Example): If there was lightening outside, the lightening (light) could travel through a tree (that you cannot see through).
The statement Light can travel through materials that you cannot see through, like wood or aluminum foil, is True.
What is light?Electromagnetic radiation that the human eye can detect as light. The wavelengths of electromagnetic radiation cover a very broad spectrum. Information about space and time is transmitted by light. This characteristic serves as the foundation for the study of optics, optical communications, and a wide range of other related, both established and developing technologies.
Lasers, holography, and fiber-optic communication systems are examples of technologies that use light manipulation. The electromagnetic spectrum, which includes all forms of light, propagates in a vacuum at the same speeds, c. only a small portion of which is visible to humans. And it is unquestionably possible for non-visible light to pass through wood, including radio waves, x-rays, and gamma-energy photons.
Therefore, the statement Light can travel through materials that you cannot see through, like wood or aluminum foil, is True.

Sam is moving house and is carrying a 300N box of books up a flight of steps 5m high, it takes her 30 seconds. Gary follows her carrying a bag of clothes doing 1000 J of work; it only takes him 25 seconds. Who provides the biggest power? Show your working.
Answers
Answer: Sam provides the biggest power
Explanation: Power is defined, in Physics, as the rate of work done. Work is energy transferred to an object due to the force causing the displacement of the object.
So, to determine Power:
For Sam:
P = [tex]\frac{work}{time}[/tex]
[tex]P=\frac{F.d}{t}[/tex]
[tex]P=\frac{300.5}{30}[/tex]
P = 50 Watts
The unit for Power is [P] = J/s = Watt
For Gary:
P = [tex]\frac{work}{time}[/tex]
[tex]P=\frac{1000}{25}[/tex]
P = 40 Watts
Comparing power of Sam and Gary, we can conclude that Sam provides the biggest power of 50 Watts.

Explain how the law of conservation of energy applied to the energy transformations that occur from the outlet charger to the ringing phone
Answers
Answer: ELECTRICAL ENERGY to CHEMICAL ENERGY to SOUND ENERGY.
Explanation:
There are laws governing the conservation of energy in physics. The first law of thermodynamics states that in a closed system, energy can neither be created nor destroyed during transformation. With this, the total energy of a given system always remains constant.
This first law of thermodynamics which arouse from special relativity, says that changes in the energy of systems will also coincide with changes in a measure of its energy content.
The ELECTRICAL energy from the outlet charger is transformed and stored as CHEMICAL energy in the battery of the phone. This in turn is converted to SOUND energy when the phone rings.
A bungee jumper starts with 1000 J in their GPE store. After they jump they fall and are brought to a stop with the bungee cord. With the cord fully stretched what is the energy in the EPE store?
Answers
Answer:
energy is equal to 1000 J
Explanation:
When the jumper is in the tent, he has a given height, this height gives him a gravitational potential energy, which forms his initial mechanical energy of 1000 J. After jumping, this energy is converted into elastic energy of the rope plus a remainder of potential energy gravitational, it does not reach the ground, but as the friction is negligible the total mechanical energy is conserved, therefore its energy is equal to 1000 J
This is a case of energy transformation, but the total value of mechanical energy does not change

Acids break down fabrics and can cause burns if the acids are strong.
Acids have a slippery feel and could result in a fall.
Answers
Answer:
Acids break down fabrics and can cause burns if the acids are strong.
Explanation:
A protective apron or lab coat is important when working with acids because acids break down fabrics and can cause burns if the acids are strong.
An acid is a substance that interacts with water to produce excess hydroxonium ions in an aqueous solution. A strong acid ionizes completely in solution. When they come in contact with a fabric, they break them down violently. So, if they come in contact with the skin, it causes a violent break down of body tissues. The apron acts a protective layer.Answer:

frequency remains the same. What is its new speed? (The equation for the
speed of a wave is v= f x.)
A. 350 m/s
B. 9,800 m/s
C. 450 m/s
D. 13 m/s
Answers
Answer:
C. 450
it should be right
The new speed of sound wave is 450 m/s. Hence, option (C) is correct.
What is sound wave?A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid matter).
Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves.
Frequency of sound wave is = 16 Hz.
Wavelength of the sound wave is = 28 m.
Hence, new speed of sound wave is = 16 × 28 meter/second
= 448 meter/second
=450 meter/second. (approx.)

The box is applying 22 N of force on the table, but the box is not moving 22 N If there is a downward force of 22 N, why is the box not moving downward?
Answers
Answer:
A reaction force
Explanation:
The box is not moving downward because the table is applying an equal and opposite amount of force on the box.
This is the premise of Newton's third law of motion which states that "action and reaction are equal and opposite".
The action force impacted by the downward pull on the table is being cancelled out by the upward force of the table.
The net force in the vertical direction will therefore be 0N This way, the box does not move downward.Given the impulse acting on an object and the impact time which equation can be used to calculate the force applied to an object
Answers
Answer is D
Ndmdjdndbdjdkskd
The impulse acting on an object and the impact time, the equation F= I / Δt can be used to calculate the force applied to an object, therefore the correct answer is D.
What is impulse?The product of the average applied force and the time for which it is exerted is known as an impulse.
the mathematical relation for impulse is
Impulse = F * Δt
where F represents the force applied and Δt represents the time for which the force is applied
Thus, the correct equation that can be used to calculate the force applied to an object is F = I /Δt and the correct option is D.
