Answer 1

Answer:

Eliminate y by adding equations (1) and (3) because the coefficients on y are opposites. Then eliminate y by multiplying equation (1) by 2 and adding it to equation (2). Eliminate z by subtracting equations (1) and (2) because the coefficients are the same. Then eliminate z by multiplying equation (3) by 2 and adding it to equation (1).

Answers

The electron sea model shows that electrons move freely among atoms (delocalized).

Metals are made up of atoms which has an array of positive ions in a sea of electrons.

The electrons can move freely within metal by detaching itself from its parent atom. Hence the electrons are said to be delocalized.

An algal bloom, also known as eutrophication, is the fast growth of algae populations in freshwater or marine water systems as a result of an overabundance of nutrients, notably phosphorus and nitrogen.

What are the causes of Cyanobacteria?

Examples of toxic algal blooms that can have detrimental effects on people's health, aquatic ecosystems, and the economy include red tides, blue-green algae, and cyanobacteria.

A cyanobacteria bloom can be caused by two factors: an abundance of nutrients, and warm water temperatures.

The main sources of extra nutrients that might cause a bloom in a water body are septic tank overflows, lawn and agricultural fertilizers, and fertilizers used on crops.

Explanation:

a rock falls for 1.43 seconds. how far did it fall?

Answers

The Answer is 10.03 m

Explanation:

Given,

time =1.43 s

distance =?

acceleration= 9.81

Now by the formula

s=ut + 1/2 gt^2

s= 0× 1.43 +1/2 (9.81)×(1.43)^2

s= 10.03 m

therefore distance = 10.03 m

The rock fell approximately 10.02 meters in 1.43 seconds in a vacuum with an acceleration of [tex]\( 9.80 \, \text{m/s}^2 \)[/tex]

To find the distance the rock fell, we can use the formula for distance traveled by an object in free fall:

[tex]\rm \[ \text{Distance} = \text{initial velocity} \times \text{time} + \frac{1}{2} \times \text{acceleration} \times \text{time}^2 \][/tex]

Given that the rock is falling from rest, the initial velocity u is 0 m/s. The acceleration due to gravity g is [tex]\rm \( 9.80 \, \text{m/s}^2 \)[/tex], and the time the rock falls t is 1.43 seconds. Plugging these values into the formula:

[tex]\[ \text{Distance} = 0 \times 1.43 + \frac{1}{2} \times 9.80 \times (1.43)^2 \]\[ \text{Distance} = 0 + \frac{1}{2} \times 9.80 \times 2.0449 \]\[ \text{Distance} = 0 + 10.0191 \]\[ \text{Distance} = 10.02 \, \text{meters} \][/tex]

So, the rock fell approximately 10.02 meters in 1.43 seconds in a vacuum with an acceleration of [tex]\( 9.80 \, \text{m/s}^2 \)[/tex]. The correct answer is indeed 10.02 meters.

a 15.0 kg block is attached to a very light horizontal spring of force constant 575 n/m and is resting on a smooth horizontal table (figure 1). suddenly it is struck by a 3.00 kg stone traveling horizontally at 8.00 m/s to the right, whereupon the stone rebounds at 2.00 m/s horizontally to the left.

Answers

The instantaneous velocity of the 15 kg. mass just after collision can be found by the principle of linear momentum.

a) The speed of the 15 kg. just after collision is 2 m/s.

b) The type of collision is inelastic collision

c) The compression of the spring is approximately 0.323 m.

Reasons:

The given parameters are;

Mass of the block attached to the spring, m₁ = 15.0 kg

Force constant of the spring, K = 575 N/m

Mass of the stone that strikes the block, m₂ = 3.00 kg

Speed of the stone, v₂ = 8.00 m/s

Speed with which the stone rebounds, v₃ = 2.00 m/s

a) The total initial momentum = 3 kg. × 8 m/s = 24 kg·m/s

The final momentum, just after collision = 3 × (-2) kg·m/s + 15 kg ×v₁

By conservation of momentum, we have;

24 kg·m/s = 3 × (-2) kg·m/s + 15 kg ×v₁

[tex]v_1 = \dfrac{24 \, kg \cdot m/s + 6 \, kg \cdot m/s}{15 \, kg} = 2 \, m/s[/tex]

The speed of the 15 kg. just after collision, v₁ = 2 m/s.

b) A collision is elastic when the kinetic energy of the collision is conserved

The initial kinetic energy, K.E.₁ = 0.5 × 3 kg. ×(8 m/s)² = 96 J

The sum of the final kinetic energy are;

0.5 × 3 kg. ×  (2 m/s)² + 0.5 × 15 kg ×  (2 m/s)² = 36 J

The initial kinetic energy ≠  The final kinetic energy

Therefore, the collision is not elastic

(c) The kinetic energy given by the block = The elastic potential energy gained by the spring

Kinetic energy of the block, K.E. = 0.5 × 15 kg ×  (2 m/s)² = 30 J

Elastic energy gained by the block = 0.5 × K × x² = 0.5 × 575 N/m × x²

Therefore;

0.5 × 575 N/m × x² = 30 J

[tex]x^2 = \dfrac{30 \, J}{0.5 \times 575 \, N/m} = \dfrac{12}{115} \, m^2[/tex]

[tex]x = 2 \cdot \sqrt{\dfrac{3}{115} } \approx 0.323[/tex]
