broo this is easy plz give me harder questions smh

Copper and tin wire are both ductile and able to be stretched.

Answer:

Explanation:

The percentage error of a certain measurement can be found by using the formula

[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]

From the question

actual density = 0.95 g/mL

error = 0.95 - 0.56 = 0.39

So we have

[tex]p(\%) = \frac{0.39}{0.95} \times 100 \\ = 41.0526315...[/tex]

We have the final answer as

D

Explanation:

A and C sounds not logic

B is wrong since all the molecules has different numbers of carbon and hydrogen

Answer:

145 hours

Explanation:

Since one hour of riding a bicycle takes up 505 kcal of energy. It is also stated that one gram of body fat is equal to 7.70 kcal. Also, it is given that 1 pound of body fat is equal to 454 g.

Hence;

1 Ib= 454 g

21 Ib= 21 × 454/1 = 9534 g

But

1g of body fat = 7.70kcal

9534 g of body fat = 9534 × 7.70 kcal/1 = 73411.8 kcal

If 505 kcal is lost in 1 hour

73411.8 kcal is lost in 73411.8 kcal × 1hour/505k cal = 145 hours

Answer:

1 closer

2 24hours

3 tidal bulges

4 in a straight line

Explanation:

Tides have been the effect of the sea with the gravitational pull of the sun and moon.

1. Earth’s tides are affected by the gravitational pull of the Sun and the Moon, but mainly the Moon because the Moon is closer to the earth.

In spite of high pull of the Sun, the distance of moon from earth results in increased effect of moon gravitational pull than Sun.

2. Each day, each coastal region on Earth experiences two high tides and two low tides in every 24 hours time period.

The daily tides has been resulted at the coast with the moon revolution around the earth's rotation.

3. This is because the gravitational attraction of the Moon creates tidal bulges on two opposite sides of the planet.

The effect of the  moon gravitational force results in the bulging or the pulling force to the sea, resulting in the diurnal tides.

4. Two spring tides occur monthly, when the Moon is in its new and full phases. During these phases, the Moon and Sun are oriented at a right angle measuring 90 degrees which gravitation pulls the water on Earth in the same direction, creating a large tidal range.

Explanation:

we know that,

From Left to right (Period) atomic radius decreases

and

From Top to bottom (Group) atomic radius increases.

Li, C, O, F belongs to same period.

So,

Atomic radius decreases if we go left to right

Increasing order of Atomic radius -

Li > C > O > F

Therefore,

Option C is correct ✔.

Explanation:

there is only one sulphur (S) atoms in the formula for sodium sulphate

The chemical formula for sodium sulfate is Na₂SO₄.One sulfur atoms are in the formula for sodium sulfate.

The term chemical formula shows the elements that create  the compound and the numbers of atoms of each element in the smallest unit of that compound, be it a molecule or a formula unit.

Chemical formulas are classified into three types: empirical, molecular, and structural.

Empirical formulas depict the simplest whole-number ratio of atoms in a compound, whereas molecular formulas depict the number of each type of atom in a molecule and structural formulas depict how the atoms in a molecule are bonded to each other.

Thus, the chemical formula for sodium sulfate is Na₂SO₄. In sodium sulphate two molecules of sodium, one atom of sulfur, and four atoms of oxygen are present.

Explanation:

Speed of Light = Wavelength times Frequency

c = λν

Step 1: Define

c = 3.0 × 10⁸ m/s

ν = 5.10 × 10¹⁴ Hz

λ = unknown

Step 2: Solve for λ

3.0 × 10⁸ m/s = 5.10 × 10¹⁴ Hz · λ

λ = 5.88235 × 10⁻⁷ m

Step 3: Simplify

We are given 3 sig figs.

5.88235 × 10⁻⁷ m ≈ 5.88 × 10⁻⁷ m

Answer:

The order is B, C, A.

Explanation:

When the liquid is first poured into the container, the entropy is still very high because there is a very large difference in color of the liquid. The more time passes, entropy becomes lower because the blue color liquid disperses through the rest of the container. So the entropy is the highest in B and lowest in A. At A the entropy is as close to 0 as it can be in this situation out of the three parts.
