Answer:

PLS PLS PLS mark brainliest

Explanation:

The following are the environmental problems caused by the invasive algae which is known as Lyngbya.

A. It blocks the sunlight from reaching the water, thereby depriving the plants in the water from accessing it. So they won't be able to manufacture their foods and eventually die off.

B. The algae produce offensive odour like rotten egg , which drive people and other organisms away.

C. The algae prevent oxygen from entering the water, and prevent the resident organisms from making use of it, which leads to their death.

D. The algae also give off heat into the chilly spring waters.

In conclusion, the goals of the Crystal River project is to save the living organisms in the river from extinction and to make it a livable environment for them.

If you're willing to consider fractions or decimals,
then there are an infinite number of answers.
Like (2.5 x 160), and (15 x 26-2/3).

If you want to stick to only whole numbers,
then these 8 combinations do:

1, 400
2, 200
4, 100
5, 80
8, 50
10, 40
16, 25

How does an object behave in differents liquids?

agasfer [191]

If the object has a lower density it will float and it if it has a higher density it will sink, different liquids may also be heavier or lighter causing a different outcome.

An ice-skater is moving at a constant velocity across an icy pond, The skater throws a snowball directly ahead.

Murljashka [212]

Answer:

(D) It is equal to the original velocity of the skater.

Explanation:

The velocity of the center of mass of a system is

$\vec{v}_{cm} = \frac{m1\vec{v}_1 + m_2\vec{v}_2}{m_1 + m_2}$

The velocity of the center of mass is constant if there is no external force, because the total momentum of the whole system is conserved.

So, before the snowball is thrown, the velocity of the center of mass is equal to that of the skater. This velocity will always be equal to the velocity of the center of mass of the system.

PLEASE HELP MEE THIS IS DUE IN 45 MINS

guajiro [1.7K]

Answer:

The distance travelled does not depend on the mass of the vehicle. Therefore, $s = d$

Explanation:

This deceleration situation can be analyzed by means of Work-Energy Theorem, where change in translational kinetic energy is equal to the work done by friction:

$\frac{1}{2}\cdot m\cdot v^{2}-\mu\cdot m\cdot g \cdot s = 0$ (1)

Where:

$m$ - Mass of the car, in kilogram.

$v$ - Initial velocity, in meters per second.

$\mu$ - Coefficient of friction, no unit.

$s$ - Travelled distance, in meters.

Then we derive an expression for the distance travelled by the vehicle:

$\frac{1}{2}\cdot v^{2} = \mu \cdot g \cdot s$

$s = \frac{v^{2}}{\mu\cdot g}$

As we notice, the distance travelled does not depend on the mass of the vehicle. Therefore, $s = d$

After Moseley's discovery in 1913, the periodic law stated that physical and chemical properties tend to repeat periodically whe

stich3 [128]

Answer:

Option B

Explanation:

The correct answer is Option B.

Before Moseley's discovery in 1913, In Mendeleev's periodic table the elements rearranged with increasing atomic mass.

Mendeleev was not able to locate hydrogen atom and late isotopes found violate Mendeleev table. The biggest drawback was that the atomic mass was not regular when moving one element to another.

But Moseley's arranged element in the periodic table with increasing atomic number.
