Explanation:

The buoyant force acting on an immersed body is equal to the weight of the fluid displaced by it, if the fluid is in rest. In this case, the fluid is accelerating upwards so the buoyant force must also provide the displaced fluid force to accelerate. Therefore, buoyant force will be fVρgeff where V = volume of body and f = fraction of volume of body immersed in fluid and geff=g+a=1.5g.

Answer:

El peso de la persona B es la mitad del peso de la persona A.

Explanation:

El peso de la persona B puede calcularse con la siguiente ecuación:

[tex] P_{B} = m_{B}g [/tex]   (1)

En donde:

[tex]m_{B}[/tex]: es la masa de la persona B

g: es la gravedad

Dado que la persona B tiene la mitad de la masa de la persona A, tenemos:

[tex] m_{B} = \frac{m_{A}}{2} [/tex]  (2)

En donde:

[tex]m_{A}[/tex]: es la masa de la persona A

Al introducir la ecuación (2) en (1) nos queda:

[tex] P_{B} = \frac{m_{A}}{2}g [/tex]   (3)

Sabemos que el peso de la persona A está dado por:

[tex] P_{A} = m_{A}g [/tex]   (4)

Entonces, al introducir la ecuación (4) en (3) tenemos:

[tex] P_{B} = \frac{P_{A}}{2} [/tex]

Por lo tanto, el peso de la persona B es la mitad del peso de la persona A.

Answer:

Consider an isolated system of 2 bodies A & B. An isolated system means where there is no external force acting.Now let F be the force acting on B by A & F be the force acting on A by B.Now rate of change of momentum of A =dpA/dt and rate of change of momentum of B =d pB/dt

thus FAB=d pB/dt (i)......

FBA=dpA/dt (ii)........

Adding 1 and 2 we get FAB+FBA=d pB/dt+dpA/dt =d(pB+pA)/dt

But if no force is applied momentum will also be 0 because no velocity will be there so rate of change of momentum will also be 0

thus d(pA+pB)/dt=0

therefore FAB+FBA=0

or,FAB=-FBA

Answer:

the forces are proportional to their areas of application

Explanation:

In a hydraulic jack, Pascal's principle is used, that the pressure in an incompressible liquid is the same at the same height, whereby the pressure on both sides of the jack are the same

           P₁ = P₂

the pressure is defined by

            P = F / A

we substitute

           [tex]\frac{F_1}{A_1} = \frac{F_2}{A_2}[/tex]

           F₂ = [tex]\frac{A_2}{A_1} \ F_1[/tex]

therefore the force is F₂> F₁

Therefore the forces are proportional to their areas of application

Answer:

a) A = 3 cm,  b)  T = 0.4 s,   f = 2.5 Hz,

2) A standing wave the displacement of the wave is canceled and only one oscillation remains

Explanation:

a) in an oscillatory movement the amplitude is the highest value of the signal in this case

          A = 3 cm

b) the period of oscillation is the time it takes for the wave to repeat itself in this case

          T = 0.4 s

the period is the inverse of the frequency

         f = 1 /T

         f = 1 /, 0.4

         f = 2.5 Hz

2) a traveling wave is a wave for which as time increases the displacement increases, in the case of a transverse wave the oscillation is perpendicular to the displacement and in the case of a longitudinal wave the oscillation is in the same direction of the displacement.

A standing wave occurs when a traveling wave bounces off some object and there are two waves, one that travels in one direction and the other that travels in the opposite direction. In this case, the displacement of the wave is canceled and only one oscillation remains.

Answer:

Por que existe una relación entre dichas magnitudes.

Para un pendulo perfecto de largo L, sabemos que el periodo esta definido como:

[tex]T = 2*\pi *\sqrt{L/g}[/tex]

Donde:

pi = 3.14

L = largo del péndulo

g = aceleración gravitatoria = 9.8 m/s^2

Entonces podemos ver que el periodo es proporcional a la raíz cuadrada de la longitud del péndulo.

Esto es por lo que al analizar datos de un experimento se debería observar una relación entre esas magnitudes.

Answer:

5

Explanation:

20 x  5 = 100

Explanation:

the PE = Weight x g x Height above ground where g is the gravitational constant (9.8m/s^2)

so tge PE = 100 x 9.8 x 25 = 24500 J

Answer:

Distancia, S = 2.84 metros

Explanation:

Dados los siguientes datos;

Velocidad inicial = 55 m/s

Velocidad final = 115 m/s

Deceleración = 14500 m/s²

Para encontrar qué tan lejos viajaría el automóvil, usaríamos la tercera ecuación de movimiento;

V² = U² + 2aS

115² = 55² + 2*14500*S

13225 = 3025 + 29000S

29000S = 13225 - 3025

29000S = 10200

S = 29000/10200

Distancia, S = 2.84 metros

Answer:

Stimulants are a group of drugs that result in increased activity in the body. Sometimes referred to as “uppers,” these drugs are frequently abused due to their performance-enhancing and euphoric effects. Generally, those who abuse stimulants experience heightened energy levels and enhanced focus.

Stimulants speed up mental and physical processes, which can produce desirable effects in the short-term by increasing levels of dopamine in the brain. While users may feel great due to the short-term effects of stimulants, long-term abuse of these drugs can have significant consequences, which is why it is so important for those who abuse the drugs to get help as quickly as possible.

The force is 35808 N.

Explanation:

Power, P = 600 hp = 600 x 746 W = 447600 W

speed, v = 45 km/h = 12.5 m/s

Let the force is F.

P = F v

447600 = F x 12.5

F = 35808 N

Explanation:

Placing one hand below the stage of the microscope and other hand must be used to hold the arm of the microscope. This facilitates the safety of the microscope as it will provide support to the entire structure of the microscope and also to the lens and mirrors attached to the structure of the microscope. If any of the part get damaged or lost during carrying it will affect the overall functioning of the microscope.
