Explanation:

Answer:

m₀ = 96 g

Explanation:

First, we will calculate the no. of half-lives passed:

[tex]n = \frac{T}{T_{1/2}}[/tex]

where,

n = no. of half-lives passed = ?

T = Total time elapsed = 32 h

[tex]T_{1/2}[/tex] = Half-Life = 8 h

Therefore,

[tex]n = \frac{32\ h}{8\ h}\\\\n = 4[/tex]

Now, for the initial amount of element:

[tex]m = \frac{m_o}{2^n}\\\\m_o = m(2^n)[/tex]

where,

m₀ = initial amount of element = ?

m = current amount of element = 6 g

Therefore,

[tex]m_o = (6\ g)(2^4)[/tex]

m₀ = (6 g)(16)

m₀ = 96 g

Answer:

160000 calories or 669440 Joules

Explanation:

Using the formula as follows;

Q = L × m

Where;

Q = amount of heat (J)

L = specific latent heat

m = mass (g)

* Latent heat (L) required for melting of ice is 80 calories/grams.

* Mass of ice in grams = 2kg × 1000 = 2000g.

Hence, Q = 80 × 2000

= 160000 Calories

1 calorie = 4.184J

160000 calorie = 160000 × 4.184

= 669440J

Answer:

1.4 m/s/s (2.s.f)

Explanation:

The formula for centripetal acceleration is:

[tex]a=\frac{v^{2} }{r}[/tex], where v is velocity and r is the radius.

In the question we are given the information that the car has a mass of 1300kg, a velocity of 2.5m/s, and a turn radius of 8.5m which are all the values we need. Therefore we can simply substitute in the values to solve the question:

[tex]a=\frac{3.5^{2} }{8.5} \\a=1.4[/tex]

Therefore the centripetal acceleration of the car is 1.4m/s/s. (2.s.f)

Hope this helped!

[tex]n = \frac{sin(i)}{sin(r)} [/tex]

[tex]1.50 = \frac{sin(30)}{sin(r)} \\ 1.50 = \frac{0.5}{sin(r)} \\ sin(r) = \frac{0.5}{1.5} \\ sin(r) = 0.3333[/tex]

Answer:

Air resistance is pushing up on the parachute and force of gravity is pulling down so she slows down. This increases friction which slows free fall down. So when the skydiver reaches terminal velocity, the force of gravity is balance by air resistance. But when the forces are balance, there is no acceleration.

Answer:

True.

Explanation:

In biology, selective breeding is the mechanism by which certain traits or a combination of traits are consciously selected in animal breeding or plant breeding and cultivation. Artificial selection is seen as a counterpart to natural selection, the mechanism by which, in nature, individuals are selected who are better adapted to their natural environment. Both processes have the same genetic principles and background.  Man selects the individuals with the desired traits to produce progeny, making these traits more and more common.

Answer:

C. Photosynthesis

Explanation:

The redox reaction given in this question is given as follows:

6H2O + 6CO2 → C6H12O6 + 6O2

In this reaction, water (H2O) reacts with carbon dioxide (CO2) to form glucose (C6H12O6) and oxygen (O2). This is the general equation for PHOTOSYNTHESIS process, which is the process whereby plants manufacture their food (sugar) by combining water and carbon dioxide.

In the equation above, water is oxidized into oxygen, while carbon dioxide is reduced into glucose. This makes it an oxidation-reduction (redox) reaction.

Answer: 2

Explanation: waves transfer energy without transferring mass

When a wave travels through a medium, the wave transfers: 2. energy, only.

A wave can be defined as a disturbance in a medium that progressively transfers (transports) energy from a source to another location, especially without the transportation of mass (matter).

Generally, the energy of a wave is directly proportional to the square of wave amplitude and the square of its frequency. Thus, a wave transfers only energy without mass when it travels through a medium.

Answer:

T = 60°C

Explanation:

We are given;

Mass of water in both cases as 60g.

Thus; m1 = m2 = 60 g

Temperature of first water; T1 = 40°C

Temperature of 2nd water; T2 = 80°C

Let final temperature be T.

To solve for the final temperature, we will use the formula;

(m1 + m2)T = ((m1•T1) + (m2•T2))

(60 + 60)T = ((60 × 40) + (60 × 80))

120T = 7200

T = 7200/120

T = 60°C

Answer: A.) concave lens

Explanation: i hope this helps shawtay :)

In general, a concave lens (also known as a diverging lens) is used to correct nearsightedness, as stated in "Take a Closer Look." Option C is correct.

A lens is an optical component that is used to refract (bend) and focus light. It is typically made of a transparent material, such as glass or plastic, and has a specific shape that allows it to alter the path of light as it passes through.

Here,
In general, a concave lens (also known as a diverging lens) is used to correct nearsightedness, as stated in "Take a Closer Look."

A concave lens is thinnest at the center and thicker at the edges, which causes light rays passing through the lens to diverge or spread out. By placing a concave lens in front of a nearsighted eye, the lens causes incoming light rays to diverge more before they reach the eye's lens, which then focuses them properly on the retina, resulting in clearer vision.

Answer:

pull up???????????????

Answer:

Sunlight is a mixture of colors. When it passes through a glass prism, some of the light is bent, or refracted, more than other portions. And just as sunlight passing through a prism is bent, so is sunlight passing through drops of water. This produces an atmospheric solar spectrum in the sky for all to see: a rainbow.

Answer:

W = 20 J

Explanation:

Given that,

The mass of a loaded sack, m = 1000 g = 1 kg

It falls down from the floor of a lorry 200 cm high, h = 2 m

We need to find the work done by the gravity. The work done by an object under the action of gravity is given by :

W = mgh

Substitute all the values,

W = 1 × 10 × 2

= 20 J

Hence, the required work done by gravity is equal to 20 J.

Answer:

You either need to lower the volume so the sounds intensity is lessened. Or you can pad the walls to absorb the sound rather than defect.

Explanation:

Sound intensity allows it to be heard further, but in an enclosed room it will start returning. Sound will deflect off of hard objects do to its interactions with solids. A softer and foamy material can dampen it.
