Answer:

The gravitational force b) Increases with increase in mass.

Explanation:

The gravitational force between two objects is given by

F=G\frac{m_1 m_2}{r^2}F=Gr2m1m2

where

G is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between the objects

From the equation, we notice that:

- The force is proportional to the masses, m1 and m2: so, if the masses increase, the force will increase, and if the masses decrease, the force will decrease

- The force is inversely proportional to the distance between the masses, r: so, if the distance increases, the force will decreases, and if the distance decreases , the force will increases

Therefore, the correct options is only:

Increases with increase in mass

Answer:

see below

Explanation:

First: Leave a couple inches of wire loose at one end and wrap most of the rest of the wire around iron u-shaped bar and make sure not to overlap the wires.

Second:Cut the wire (if needed) so that there is about a couple inches loose at the other end too.

Third: Now remove about an inch of the plastic coating from both ends of the wire and connect the one wire to one end of a battery and the other wire to the other end of the battery.

1. Explique con sus palabras por qué el ser humano al nacer es un organismo inacabado, y que influencia ejercen en él las caract

Vlad [161]

Answer:

Todo ser humano, al nacer, es un organismo inacabado en términos tanto físicos como psicoemocionales. Es decir, el humano, al nacer, lo hace sin la posibilidad de autosustentarse en el futuro inmediato: no puede caminar, expresarse, tener pensamiento analítico ni la capacidad de resolver las problemáticas que les afectan.

Ello hace que el humano requiera para su desarrollo de un acompañamiento absoluto por parte de su madre en el período inicial de su vida, tanto para alimentarlo como para transmitirle las nociones básicas de supervivencia; y posteriormente requiera de un entorno social idóneo que le permita desarrollarse emocionalmente para poder vivir normalmente en sociedad.

Además, respecto de sus características físicas, necesita también aprender a caminar, movilizarse y demás atributos físicos que le garanticen un normal desarrollo motor, con lo cual es fundamental que dicha enseñanza provenga también del entorno que lo rodea.

Your office has a 0.025 m^3 cylindrical container of drinking water. The radius of the container is about 13 cm. Required:a. Whe

uranmaximum [27]

Answer:

a) 105935.7 Pa

b) 103630.35 Pa

Explanation:

The volume of the container = 0.025 m^3

The radius of the container = 13 cm = 0.13 m

We have to find the height of the tank

From the equation for finding the volume of the cylinder,

V = $\pi r^2h$

where

V is the volume of the cylinder

h is the height of the cylinder

substituting values, we have

0.025 = 3.142 x $0.13^2$ x h

0.025 = 0.0531h

h = 0.025/0.0531 = 0.47 m

Pressure at the bottom of the tank P = ρgh

where

ρ is the density of water = 1000 kg/m^3

g is the acceleration due to gravity = 9.81 m/s^2

h is the depth of water which is equal to the height of the tank

substituting values, we have

P = 1000 x 9.81 x 0.47 = 4610.7 Pa

atmospheric pressure = 101325 Pa

therefore, the pressure in the tank bottom above atmospheric pressure = 101325 Pa + 4610.7 Pa = 105935.7 Pa

b) For half way down the container, depth of water will be = 0.47/2 = 0.235 m

pressure P = 1000 x 9.81 x 0.235 = 2305.35 Pa

This pressure above atmospheric pressure = 101325 Pa + 2305.35 Pa = 103630.35 Pa
