Answer:

They are theories which have a really dark twist or meaning behind the whole theory, some conspiracy theories can also lead to a cliffhanger.

Answer:

The answer is "They involve changes in energy".

Explanation:

Energy change is quite important in chemicals because nearly all reactions involve activation energy. They will learn and learn how to utilize different types of energy shifts in the steam cycle. A conversation about what drives chemical processes contributes to entropy and natural energy principles. It may shift from the shape of form. For example, chemicals might change to heat. Laser light can turn substances into power. Its energy can be changed into different kinds, but not wasted or produced.

Explanation:

It is false that one cannot classify matter based on chemical properties.

Matter is the scientific term for any type of material. Matter is defined as anything with mass that occupies space.

Matter requires at least one subatomic particle, though most matter is made up of atoms. A pure substance is sometimes referred to as matter.

Solids, liquids, and gases are the three forms or phases of matter. A substance is defined as matter that is homogeneous and has identical parts.

Substances are classified as either elements or compounds. Elements are pure substances that cannot be chemically decomposed into simpler substances.

Chemically, matter can be classified as pure substance elements and compounds, mixture, or impure substance.

Thus, the given statement is false.

Answer:

Elastic potential energy  E = 0.5 J

Explanation:

Let us assume we have to find the elastic potential energy stored in the spring.

Given: k = 100

change in the length of the spring x = 0.2-0.1 = 0.1 m

Elastic potential energy

E = [tex]\frac{1}{2} kx^2[/tex]

plugging the values we get

[tex]E = 0.5\times100\times0.1^2\\=0.5 J[/tex]

Hence, Elastic potential energy  E = 0.5 J

Explanation:

Respuesta:

0,0560 cal / gºC.

Explicación:

Cantidad de calor; (Q)

Q = mcΔt; Δt = t2 - t1

m = masa, c = capacidad calorífica específica; Δt = cambio de temperatura

c de agua = 1 cal / gºC

c de aluminio = 0,22 cal / gºC

QTotal = Q de agua + Q de aluminio

Q de agua = 450 * 1 * (26 - 23) = 1350 cal

Q de aluminio = 60 * 0.22 * (26 - 23) = 39.6 cal

QTotal = 1350 + 39,6 = 1389,6 cal

Calor perdido = calor ganado

QTotal = calor perdido

- 1389,6 = 335,2 * c * (26 - 100)

-1389,6 = −24804,8 * c

c = 1389,6 / 24804,8

c = 0,056021 cal / gºC.

Capacidad calorífica específica de la plata = 0,0560 cal / gºC.

Answer:

a) The distance covered by the moving object is approximately 18.85 km

b) The magnitude of the displacement of the object is 0 (no displacement)

Explanation:

From the drawing, we have;

The sale of the drawing is 1 unit = 1 km

The radius of the circle in the drawing along which the object moves = 3 units

Therefore;

The radius of the circle along which the object moves, r = 1 km/unit × 3 units = 3 km

a) The distance covered by the object that moves from point A to B to C to D and finally to A is equal to the circumference of the circle

Therefore;

The distance covered by the moving object, d = 2·π·r

By pugging the value for r = 3 km

d = 2 × π × 3 km = 6·π km ≈ 18.85 km

The distance covered by the moving object, d ≈ 18.85 km

b) The displacement = The object's change in position

The initial position of the object = Point A

The final position of the object = Point A

Therefore, the displacement of the object, A = No displacement = 0 (No difference between the initial and final location of the object

Answer:

is this the full question?

Explanation:

Answer:

(a) Luna

(b) Luna

Explanation:

(b)

The final speed can be found by using the third equation of motion:

[tex]2as = v_f^2 - v_i^2\\[/tex]

where,

a = acceleration

s = distance covered

vf = final speed

vi = initial speed

For Angela:

a = 2 m/s²

s = 30 m

vi = 4 m/s

vf = v_fa

therefore,

[tex]2(2\ m/s^2)(30\ m) = (v_{fa})^2 - (4\ m/s)^2\\v_{fa}^2 = 120 m^2/s^2 + 16\ m^2/s^2\\v_{fa} = 11.66\ m/s\\[/tex]

For Luna:

a = 3 m/s²

s = 30 m

vi = 3 m/s

vf = v_fl

therefore,

[tex]2(3\ m/s^2)(30\ m) = (v_{fa})^2 - (3\ m/s)^2\\v_{fa}^2 = 180 m^2/s^2 + 9\ m^2/s^2\\v_{fa} = 13.74\ m/s\\[/tex]

Therefore, Luna will be running faster at the end of the race.

(b)

To calculate the time of completion we will use the first equation of motion:

[tex]v_f = v_i + at[/tex]

FOR ANGELA:

[tex]11.66\ m/s = 4\ m/s + (2\ m/s^2)t_a\\t_a = \frac{7.66\ m/s}{2\ m/s^2}\\\\t_a = 3.83\ s[/tex]

FOR LUNA:

[tex]13.74\ m/s = 3\ m/s + (3\ m/s^2)t_l\\t_l = \frac{10.74\ m/s}{3\ m/s^2}\\\\t_l = 3.58\ s[/tex]

Hence, LUNA finishes the race first.

Answer:

80 volts.

Explanation:

From the question,

Applying Ohm's law

V = IR...................... Equation 1

Where V = Voltage, I = maximum current of the bulb, R = Resistance of the bulb.

Given: I = 10 A, R = ohms

Substitute these values into equation 1

V = 10×8

V = 80 volt.

Hence the voltage that can be applied is 80 volt.

Answer:

[tex]\alpha =434312\ rev/s^2[/tex]

Explanation:

Given that,

Initial angular speed, [tex]\omega_i=0[/tex]

Final angular speed, [tex]\omega_f=466\ rpm[/tex]

Angular displacement, [tex]\theta=0.25\ rev[/tex]

We need to find the angular acceleration of the CD. Using third equation of rotational kinematics as follows :

[tex]\omega_f^2-\omega_i^2=2\alpha \theta\\\\\alpha =\dfrac{\omega_f^2-\omega_i^2}{2\theta}\\\\\alpha =\dfrac{466^2-0^2}{2\times 0.25}\\\\\alpha =434312\ rev/s^2[/tex]

So, the angular acceleration of the CD is equal to [tex]434312\ rev/s^2[/tex].
