Answer: 0.5334

Explanation:

i got it right on accellus :p

Volume of value V = 0.5333 [tex]m^{3}[/tex]  is below the water line .

Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid.

F(b) = rho*g*V

F(b) = buoyant force

rho = fluid density

g = acceleration due to gravity

V = fluid volume

given

density of raft = 373 kg/[tex]m^{3}[/tex]

volume of raft = 1.43 [tex]m^{3}[/tex]

since, density  = mass / volume

mass of raft = density * volume

                    = 373 * 1.43 = 533.3 kg

using Archimedes principal

Force = density of liquid * volume of liquid displaced * acceleration due to                gravity

  mg        = 1000 * V * 9.8

  533.3 * 9.8 = 1000 * V * 9.8

  V = 0.5333 [tex]m^{3}[/tex]

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.

Answer:

When the apple falls from the tree, it has some gravitational potential energy due to its height. Now, When it starts falling, the Gravitation Potential energy will starts converting into the Kinetic Energy. When the apple is about to strikes the ground, the Gravitational Potential energy have been converted into the Kinetic Energy.

Explanation:

The potential energy will be low when its kinetic energy is high and vice versa. But the mechanical energy remains conserved.

Mechanical energy can be explained as the sum of kinetic energy and potential energy that can be used to do work. Mechanical energy can be described as the energy of a body due to its motion or position.

The total mechanical energy of a physical system is conserved as the energy can not be created or destroyed. The mechanical energy of a physical system can only be transformed from one form to another when the forces acting work are conservative in nature.

Each force is related to potential energy form and the energy changes between different kinds of potential energy and kinetic energy but the total energy remains constant.

The mechanical energy of the apple remains conserved. As the apple falls its potential energy is converted into kinetic energy.

Answer:

A non-contact force is a force applied to an object by another body that is not in direct contact with it.

Explanation:

Answer:

0.25 m

Explanation:

Given that,

The speed of sound, v = 330 m/s

The frequency of the note of the instrument, f = 1320 Hz

We need to find the wavelength of the sound wave.

We know that,

Wavelength, [tex]\lambda=\dfrac{v}{f}[/tex]

Put all the values,

[tex]\lambda=\dfrac{330}{1320}\\\\\lambda=0.25\ m[/tex]

So, the wavelength of the sound wave is equal to 0.25 m.

La opción correcta es la A) 22 km y 78 km.

Explanation:

Dado que el desplazamiento (D) es un vector, su valor viene dado por la suma algebraica de los vectores del desplazamiento de ambos tramos.

Como en el primer tramo movil se mueve en la dirección de x-positiva y en el segundo tramo se mueve en el sentido de x-negativo, tenemos:

[tex] D = (60 km - 10 km) - (60 km - 32 km) = 22 km [/tex]  

Ahora, la distancia (d) es una magnitud escalar, por lo que su valor viene dado por la suma del desplazamiento de ambos tramos:

[tex] d = (60 km - 10 km) + (60 km - 32 km) = 78 km [/tex]                

Por lo tanto, la opción correcta es la opción A) 22 km y 78 km.

Answer:

It represents Distance.

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.
