The corn plants in the image below have been grown with Lepidoptera sp. larvae, insects that feed on the corn’s cob and leaves. Select the statement that is correct, based on the image.
A. A resistance gene was inserted into the plant on the right, but the corn is still vulnerable to Lepidoptera sp. larvae.
B. A resistance gene was inserted into the plant on the right that makes the corn resistant to Lepidoptera sp. larvae.
C. A resistance gene was inserted into the plant on the left that makes the corn vulnerable to Lepidoptera sp. larvae.
D. A resistance gene was inserted into the plant on the right, but the corn cob is mutated.
Answers
Answer:
Option D is correct
Explanation:
The image on the left is the control plant which means it is the normal plant that is allowed to grow under normal regular condition so that its parameter can be compared with the parameters of the transformed plant on the right. Thus, plant on the right has been introduced with the resistance gene and hence it possess mutated cob and leaves that are not attacked by the Lepidoptera sp. larvae
Hence, option D is correct

A.)How many electrons pass through the TV per minute?
B.)How much electrical energy does the TV convert to other forms of energy
per minute?
Answers
Answer:
Explanation:
current measures charge flowing per second .
A current of .867 A means charge of .867 coulomb is flowing per second
charge flowing per minute = .867 x 60
= 52.02 coulomb
one electrons carries a charge of 1.6 x 10⁻¹⁹ Coulomb
So no of charge flowing per minute
= 52.02 / 1.6 x 10⁻¹⁹
= 32.5 x 10¹⁹ .
B )
electrical energy consumed per minute
= V X I X t , V is volt , I is current and t is time .
= 122 x .867 x 60
= 6346.44 J .

At what point in a waterfall, do the drops of water contain the most gravitational potential energy?
Answers
Answer:
The water above receives energy as it falls down the short waterfall. This energy was stored as potential energy in the gravitational field of the Earth and came out of storage as the water dropped. This energy which came out of the gravitational field ended up being expressed as the kinetic energy of the water. That is, the water gains kinetic energy as it drops. An ounce of water is going faster when it hits the bottom of the waterfall than it was when it went over the top of the waterfall
Explanation:
The drops of water contain the most gravitational potential energy at the top before they start falling.
At the top of the waterfall
GravitationAt the top of the waterfall, the water drops have the most gravitational potential energy before they start falling as the water at the peak of the waterfall is higher in the Earth's gravitational field and has gravitational potential energy. The potential energy is converted to kinetic energy when it falls. As a result, energy is not created; it was always there, stored as potential energy.
Potential energy is energy that is stored and is determined by the relative positions of various pieces of a system. Kinetic energy is the energy that an item or particle has as a result of its movement.

Answers
Answer:
The acceleration of the bag of sand is [tex]1\ m/s^2[/tex].
Explanation:
We have,
Mass of a bag of sand is 100 kg
Weight of the bag of sand is 100 N
It is required to find the acceleration of the bag when it is dropped. The weight of an object is given by :
[tex]F =ma[/tex]
When it is dropped, a = g
[tex]g=\dfrac{F}{m}\\\\g=\dfrac{100}{100}\\\\g=1\ m/s^2[/tex]
So, the acceleration of the bag of sand is [tex]1\ m/s^2[/tex].

Answers
Answer:
C is correct
Explanation:
The order of the surface temperature of the stars, starting from the highest to the lowest is Y > X > W > Z.
What is Wien's displacement law ?Wien's displacement law states that, the black-body radiation curve for different temperatures will have different peaks of wavelengths and the wavelength is inversely proportional to the surface temperature.
Here,
According to Wien's displacement law,
The wavelength of the star is inversely proportional to its surface temperature.
λ [tex]\alpha[/tex] 1/T
where T is the surface temperature.
Therefore, the star with lowest wavelength will have the highest surface temperature.
Consider the wavelengths of each stars given,
The increasing order of their wavelengths can be written as,
λ(Orange) > λ(Yellow) > λ(White) > λ(Blue)
Therefore the increasing order of their surface temperatures will be,
T(Blue) > T(White) > T(Yellow) > T(Orange)
Hence,
The order of the surface temperature of the stars, starting from the highest to the lowest is Y > X > W > Z.

When a current flows through a light bulb, it emits 30 J light energy in 2 seconds, What is the power of the bulb?
Answers
The power of the light bulb is 15 watts.
What is power ?Power in physics is defined as the rate of energy per unit time or in other words the work done by any electrical appliance per unit time. Power is expressed as -
P = E/T where E is Energy and T is the time period.
How to calculate the value of power in the question ?Given that the light bulb emits 30 J light energy in 2 seconds.
We have E = 30J and T = 2 seconds.
Therefore power(P) = Energy(E) / Time(T)
∴ P = 30 / 2 = 15 watts
Thus the power of the light bulb is 15 watts.

A flowerpot that has a mass of 1.5 kg is sitting on a windowsill 30 meters from the ground. Is the energy of the flowerpot potential of kinetic?
How much energy does the flowerpot have?
Answers
Answer:
Potential energy
441 joules
Explanation:
The flower pot is not moving so it does not have kinetic energy. Anything that is still and a distance from the ground does have potential energy.
Amount of energy: p=mggh
p=1.5(9.8)(30)=441 joules
The flower pot's energy is measured in potential energy since it is remaining stationary and the energy is stored, the flowerpot is not moving about so it is not kinetic energy.
The formula for potential energy is:
GPE = mgh
The m stands more mass, the g stands for gravitational energy (9.8m/s^2) and the h stands for height.
Our values for the following terms are:
M = 1.5kg
G = 9.8m/s^2
H = 30 meters
Now, we can plug it into our formula to solve for the amount of potential energy.
GPE = 1.5(9.8)(30)
First, let's multiply the gravitational energy and the height.
30 x 9.8 = 294
Then, multiply the mass by the result.
1.5 x 294 = 441
Therefore, the potential energy of the flowerpot is 441J.

Dinesh wants to launch a package over the garden wall to his friend on the other side. His plan is to set up a see-saw, put the package on one end and jump on the other end. Dinesh determines that he will land on the board with a force of 1,127 newtons, and the package weighs 322 newtons. The board he is going to use for the see-saw is 9 meters long. How close to the end of the board should Dinesh put the fulcrum?
Answers
Answer:
Dinesh should put the fulcrum 2 m from himself and 7 m from the package.
Explanation:
Let the fulcrum be x meters from Dinesh's end.
The sum of clockwise moment must balance the sum of anti-clockwise moment.
Taking a moment about the fulcrum
(Force exerted by Dinesh) × (Distance of Dinesh from the fulcrum) = (Weight of the package) × (Distance of the package from the fulcrum)
Force exerted by Dinesh = 1127 N
Distance of Dinesh from the fulcrum = x m
Weight of the package = 322 N
Distance of the package from the fulcrum = (9 - x) m
1127 × x = 322 (9 - x)
1127x = 2,898 - 322x
1127x + 322x = 2,898
1449x = 2898
x = (2898/1449) = 2 m
Hence, Dinesh should put the fulcrum 2 m from himself and 7 m from the package.
