Explanation:

Energy pyramid: is a model that shows the flow of energy from one feeding level to the next in an ecosystem. It compares the energy used by organisms at each trophic level.

Unit: kilocalories (kcal).

While Biomass pyramid is a statistical graph that shows the biomass present in a unit area of various trophic levels. It shows the relationship between biomass and trophic level. It quantifies the amount of biomass available in each trophic level of an energy community at a given time.

Unit: grams per square meter (g/m^2), or calories per square meter (K/m^2).

Solve for (b) how many revolutions it takes for the cd to reach its maximum angular velocity in 1.36s?

Digiron [165]

Angular displacement of the cd is 3.25 rev

Explanation:

The question is incomplete. It is not given what is the maximum angular velocity of the cd.

Here we are going to assume that the maximum angular velocity is:

$\omega = 30 rad/s$

The motion of the cd is an accelerated angular motion, therefore we can use the following suvat equation:

$\theta = (\frac{\omega_0 + \omega}{2})t$

where:

$\theta$ is the angular displacement of the cd during the time interval t

$\omega_0$ is the initial angular velocity of the cd

$\omega$ is the final angular velocity

Here we have:

t = 1.36 s

$\omega_0 = 0$ (assuming the cd starts from rest)

Therefore, the angular displacement of the cd during this time is:

$\theta=(\frac{0+30}{2})(1.36)=20.4 rad$

And since $1 rev = 2 \pi rad$ , we can convert into number of revolutions completed:

$\theta = 20.4 rad \cdot \frac{1}{2\pi rad/rev}=3.25 rev$

Answer:

The leaf cells would be unable to convert the sun's energy to make food.

Explanation:

The chloroplast in the leaf are used to make food for the plant. If the leaf loses its chloroplast, the leaf with not be able to use solar energy to manufacture their food.

During photosynthesis, green plants manufacture their food.
They use sunlight to cause a reaction between carbon dioxide and water.
The sunlight is trapped using chlorophyll present in the leaf.
In the absence of the chlorophyll contained in the chloroplast, no solar energy would be generated to cause the reaction to take place.

2. A Formula One race car speeds up from rest to 27.8 m/s in a distance of 25 meters.

Nadya [2.5K]

Answer:

Correct answer: a = 15.46 m/s²

Explanation:

The formula for accelerated movement with the given data is:

V² - V₀² = 2 · a · d where the initial velocity V₀ and the final V

Since the initial velocity V₀ is zero, the formula is:

V² = 2 · a · d => a = V² / (2 · d) = 27.8² / (2 · 25) = 772.84 / 50 = 15.46 m/s²

a = 15.46 m/s²
