Answer;

D. Most of the energy from photosynthesis flows out as heat.

Explanation;

-Energy flow is the amount of energy that moves through a food chain. The energy input, or energy that enters the ecosystem, is measured in Joules or calories.

-The largest source of energy for an ecosystem is the sun. Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism.

A student measured the mass and volume of an object using a triple beam balance and a graduated cylinder. The sample has a mass

Alisiya [41]

Answer:

3.45g/cm³

Explanation:

The density of a substance/object can be calculated by using the formula:

Density = mass/volume

Where;

Density = g/cm³

Mass = grams

Volume = cm³

According to this question, a student measured the mass and volume of an object using a triple beam balance and a graduated cylinder. The sample has a mass of 22.4 grams and a volume of 6.5cm³.

Hence, the density of the object can be calculated this;

Density = mass/volume

Density = 22.4/6.5

Density = 3.4461

To the nearest hundredth, the density of the object = 3.45g/cm³

When the distance between the balls decreases, the size of the arrows increases. This shows that the gravitational pull

shepuryov [24]

True

Explanation:

The statement that when the distance between the balls decreases, the size of arrow increases because it shows the gravitational pull between the two balls which increases is true.

According to Newton's law of universal gravitation:

"The gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of their separation".

Mathematically, the law is written as:

F = $\frac{G m_{1} m_{2} }{r^{2} }$

F is the gravitational force

G is the universal gravitational constant

m is the mass of the body

r is the distances between them.

We see that the less the distance between the two bodies the more the gravitational force they have.
