Explanation:

The healing of a cut finger. Is it a physical or chemical change? Explain.

Answers

i would say it’s more chemical than it is physical. when you cut yourself there’s usually blood, correct? because a blood clot forms here & cells begin to work on the wound, which would be physical. the chemical part though is there’s an enzyme I think called thrombin which helps the formation of fibrin mesh. this helps stable the blood clot while the cells heal & close the wound with a potential small scar.

Wound healing is a chemical change.

A chemical change involves the formation of a new substance. A substance changes form from one form into another in the process. A physical change does not involve the formation of new substances. Wound healing involves a number of chemical changes.

A wound can also be referred to as a tissue damage. When a tissue is damaged, bleeding results. Bleeding could lead to so much loss of blood.

The human body has mechanisms in place to combat this excessive loss of blood. This occurs when a complex biochemical pathway leads to the formation of fibrinogen. The enzyme thrombin converts fibrinogen to fibrin. The formation of fibrin is very essential to the wound healing process.

We can see that a series of chemical changes are involved in the process of wound healing when your finger is cut.

Sam is making an aquaponics garden. He needs 2.3 dkg of granite. He has 460 g. How much more does he need? Explain your answer with your work. ​

Answers

Explanation:

He needs 2.3 dkg

dkg is a unit of mass and represents dekagrams.

The relationship between dkg and g is given as;

1 dkg = 10g

This means he needs 2.3 * 10 = 23 g of graphite.

Since he already has 460g of graphite, he doesn't need any additional graphite.

When setting up a conversion, where does the initial unit go in the conversion factor?​

Answers

Answer:

All these conversion factors are equal to 1. If it doesn't seem obvious at first, think about it for a second. Realize that 1 minute is equivalent to 60 seconds. Simply replace 1 minute in the fraction with its equivalent 60 seconds and it becomes clear that 60 seconds / 60 seconds = 1. Numerator and denominator are equivalent; they are just expressed differently.

Explanation:

The initial unit cancels out and goes into the new unit

In science, we often need to convert from one unit to another to ensure accuracy of our calculations.

Let's say i want to convert 500 minutes to seconds.

The conversion factor is as follows;

60 seconds make 1 minute

x seconds make 500 minutes

x = 60 seconds * 500 minutes/1 minute

x = 30,000 seconds

Hence the initial unit which is "minutes" is canceled  out and the new unit "seconds" remains.

d. 50 m/h west​

Answers

Answer:

d

Explanation:

The train will travel for 2 hours to travel a distance of 100 miles with a speed of 50m/h. Therefore, option (C) is correct.

What is the speed?

The speed of a body is defined as the rate of change in the position of a body w.r.t. time.

Speed is a scalar parameter with both magnitude and no direction. A simple mathematical formula common way to determine speed.  

S = d / t

where S is the speed, d is the distance moved by a body and t is the time.

Although the SI unit for speed is the same as velocity is m/s and can also be expressed in miles per hour (mph), and kilometers per hour (kph).

Given, the distance traveled by train, d = 100 miles

The time taken by train = 2 hrs

The speed of the train = distance/ time = 100/2 = 50m/h

Conversion is a multi-stage procedure, which requires a numerical factor to multiply or divide and the appropriate selection of a number of important digits.

Using the International System Units for Conversions Factors.

(a)

If 1 g = 0.001 kg

10.5 g will be:

[tex]\mathsf{= \dfrac{10.5 \ g \times 0.0001 \ kg}{1 \ g}}[/tex]

= 0.00105  kg

(b)

If 1 km = 1000 m

1.57 km will be:

[tex]\mathsf{= \dfrac{1.57 \ km \times 1000\ m}{1 \ km} }[/tex]

= 1570 m

(c)

If 1 ug = 1 × 10⁻⁵ g

3.54 ug will be:

[tex]\mathsf{= \dfrac{3.54 \mu g \times 1 \times 10^{-5} \ g }{1 \ \mu g}}[/tex]

= 3.54 × 10⁻⁵ g

(d)

If 1 mol = 10⁶ umol

3.5 mol will be:

[tex]\mathsf{= \dfrac{3.5 \ mol \times 10^6 \ u \ mol}{1 \ mol} }[/tex]

= 3.5 × 10⁶ umol

(e)

If 1 L = 1000 mL

1.2 L will be:

[tex]\mathsf{=\dfrac{1.2 \ L \times 1000 \ mL}{1 \ L}}}[/tex]

= 1200 mL

(f)

If 1 cm = 0.000001 m³

358 cm will be:

[tex]\mathsf{= \dfrac{358\ cm \times 0.000001 m^3}{1 \ cm}}[/tex]

= 3.58 × 10⁻⁴ m³

An ice cube is left on the kitchen counter. After some time, the ice cube melts into a small puddle of water.According to the law of conservation of mass, how does the mass of the puddle of water compare to the mass of the original ice cube

Answers

Answer:

Mass of the water is equal to the mass of ice

Explanation:

When ice melts, the mass remains the same even though its volume decreases leading to a decrease in density of water.

The mass remains the same because according to the law of conservation of mass, mass can neither be created nor destroyed. Since mass is neither created nor destroyed in the process of melting, the mass of water must remain the same.

Materials expand when heated. Consider a metal rod of length L0 at temperature T0. If the temperature is changed by an amount ΔT, then the rod’s length changes by ΔL=αL0ΔT, where α is the thermal expansion coefficient.

(c) Express length L as a function of T and α if L0=60in. at T0=150∘C.
(Use symbolic notation and fractions where needed.) L(T,α)=

Answers

Answer:

(a) The length at temperature 180°C is 40.070 cm

(b) The length at temperature 90°C is 64.976 inches

(c) L(T, α) = 60·α·T - 9000·α + 60

Explanation:

(a) The given parameters are

The thermal expansion coefficient, α for steel = 1.24 × 10⁻⁵/°C

The initial length of the steel L₀ = 40 cm

The initial temperature, t₀ = 40°C

The length at temperature 180°C = L

Therefore, from the given relation, for change in length, ΔL, we have;

ΔL = α × L₀ × ΔT

The amount the temperature changed ΔT = 180°C - 40°C = 140°C

Therefore, the change in length, ΔL, is found as follows;

ΔL = α × L₀ × ΔT = 1.24 × 10⁻⁵/°C × 40 × 140°C = 0.07 cm

Therefore, L =  L₀ + ΔL = 40 + 0.07 = 40.07 cm

The length at temperature 180°C = 40.07 cm

(b) Given that the length at T = 120°C is 65 in., we have;

The temperature at which the new length is sought = 90°C

The amount the temperature changed ΔT = 90°C - 120°C = -30°C

ΔL = α × L₀ × ΔT = 1.24 × 10⁻⁵/°C × 65 × -30°C = -0.024375 inches

The length, L at 90°C is therefore, L = L₀ + ΔL = 65 - 0.024375 = 64.976 in.

The length at temperature 90°C = 64.976 inches

(c) L = L₀ + ΔL  = L₀ +  α × L₀ × ΔT = L₀ +  α × L₀ × (T - T₀)

Therefore;

L = 60 +  α × 60 × (T - 150°C)

L = 60 + α × 60 × T - 9000 × α

L(T, α) = 60·α·T - 9000·α + 60
