¿Cuál es el parámetro que indica la cantidad de energía liberada en un movimiento sísmico?

Answer:

The symbols used in language have no direct relationship between the word and the object or idea. Underextension in language occurs when a child incorrectly uses one word to describe other objects or actions that are similar to that word. ... Morphemes are the smallest distinctive sound units in a language.

A. 95 Cal is equivalent to 397480 J

B. The final speed of the object is 625.78 m/s

C. The final temperature of the water is 46.8 °C

A. Converting 95 Cal to Joules

1 Cal = 4184 J

Therefore,

95 Cal = 95 × 4184

Thus, 95 Cal is equivalent to 397480 J

B. Determination of the speed of the object

Kinetic energy (KE) = 397480 J

Mass (m) = 2.03 Kg

KE = ½mv²

397480 = ½ × 2.03 × v²

397480 = 1.015 × v²

Divide both side by 1.015

v² = 397480 / 1.015

Take the square root of both side

v = √(397480 / 1.015)

Therefore, the speed of the object is 625.78 m/s

C. Determination of the final temperature of the water

Mass of water (M) = 3.79 kg

Initial temperature of water (T₁) = 21.7 °C

Specific heat capacity of water (C) = 4186 J/KgºC

Heat (Q) = 397480 J

Q = MC(T₂ – T₁)

397480 = 3.79 × 4186 (T₂ – 21.7)

397480 = 15864.94 (T₂ – 21.7)

Clear the bracket

397480 = 15864.94T₂ – 344269.198

Collect like terms

397480 + 344269.198 = 15864.94T₂

741749.198 = 15864.94T₂

Divide both side by 15864.94

T₂ = 741749.198 / 15864.94

Therefore, the final temperature of the water is 46.8 °C

(1) The voltage drop in the second resistor is 10 V.

(2) The voltage drop across each resistor will all double to match change in resistance.

The given parameters:

The total voltage in a series circuit is given as;

[tex]V_T = IR_1 + IR_2\\\\V_T = V_1 + V_2[/tex]

The voltage drop in the second resistor is calculated as follows;

[tex]V_2 = V_T - V_1\\\\V_2 = 15 - 5\\\\V_2 = 10 \ V[/tex]

(2)

The resistance of the circuit:

[tex]R = \frac{V}{I} = \frac{10}{2} = 5 \ ohms[/tex]

When the total resistance is doubled;

In series circuit, the current in each resistor is constant, the voltage drop is calculated as;

[tex]V = IR\\\\V = 2 (5+5)\\\\V = 20 \ V[/tex]

Thus, we can conclude that the voltage drop across each resistor will all double to match change in resistance.

Hi there!

(A)

When the rock reaches the peak, it will have a vertical velocity of 0 m/s. We can use the equation:

vf = vi + at

vf = final velocity (0 m/s)

vi = initial velocity (2 m/s)

a = acceleration (in this situation, due to gravity = 9.8 m/s²)

t = time (s)

0 = 2 + (-9.8)t

2/9.8 = t = .204 sec

(B)

Use the equation:

d = vit + 1/2at²

d = 2(.204) + 1/2(-9.8)(.204²)

d = .204 m

Answer:

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question

mass = 1 kg

acceleration = 4 m/s²

We have

force = 1 × 4 = 4

We have the final answer as

(a) The tangential speed of the discus at the release is 15 m/s.

(b) The centripetal acceleration of the discus is 225 m/s².

(c) The centripetal force on the discus is 360 N.

The given parameters;

The tangential speed of the discus at the release is calculated as follows;

[tex]v = \omega r\\\\v = 15 \ rad/s \ \times 1 \ m\\\\v = 15 \ m/s[/tex]

The centripetal acceleration of the discus is calculated as follows;

[tex]a_c = \frac{v^2}{r} \\\\a_c = \frac{15^2}{1} \\\\a _c = 225 \ m/s^2[/tex]

The centripetal force on the discus is calculated as follows;

[tex]F_c = ma_c\\\\F_c = 1.6 \times 225\\\\F_c = 360 \ N[/tex]

Answer:

467 watts

Explanation:

Power is = to work/time. Work is = to force (N) times distance from starting point. So first, calculate work. 120N x14m , which is equal to 1680 joules. so then plug it into your power formula. 1680 joules/ 3.6 seconds= 466.666...7, which rounds to 467 watts.

Answer:

air and water

Explanation:

The matter through which a mechanical wave travels is called the medium (plural, media). There are three types of mechanical waves: transverse, longitudinal, and surface waves. They differ in how particles of the medium move when the energy of the wave passes through. The particles in a medium become disturbed and pass on this disturbance to the next one, and so on. So, the disturbance caused by the particles can travel through a medium such as air, ocean water, land, violin strings, Slinky coils, etc. Sound waves can travel through solids, liquids, or gases.
