Which answer is consistent with a replacement of light bulb that will increase
the intensity (brightness) of the light in a room

Answers

Answer 1

Answer:

What increases the brightness of a light bulb?

Increasing the voltage increases the brightness of the bulb. When a bulb in a series circuit is unscrewed all bulbs in the circuit go out. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. ... Bulbs in parallel are brighter than bulbs in series.

on which factor does gravitation between any two bodies depend?​

Answers

It depends on distance and size

Answer:

Gravitational force between two bodies depends on:

1. Masses of the two bodies. The greater an object's mass, the greater its gravitational force.

2. Distance of separation between them. The smaller the distance greater is the gravitational force.

Se dea caer una pelota de basquetbol desde una altura de 90 metros.Calcular: El tiempo en que demorara en caer y a velcidad con la que llega al suelo

Answers

Answer:

1. t = 4.24 s

2. [tex]v_{f} = 42.43 m/s [/tex]

Explanation:

Podemos encontrar el tiempo de caída con la siguiente ecuación:

[tex] v_{f} = v_{0} + gt [/tex]   (1)

En donde:

[tex] v_{f}[/tex]: es la velocidad final de la pelota  

[tex] v_{0}[/tex]: es la velocidad inicial = 0 (se deja caer)

g: es la aceleración debida a la gravedad = 10 m/s²

Debemos hallar primero la velocidad final. Podemos usar la ecuación:

[tex] v_{f}^{2} = v_{0}^{2} + 2gh [/tex]  (2)

En donde:

h: es la altura = 90 m

[tex] v_{f} = \sqrt{2gh} = \sqrt{2*10 m/s^{2}*90 m} = 42.43 m/s [/tex]

Entonces, la velocidad con la que la pelota llega al suelo es 42.43 m/s.

Ahora podemos encontar el tiempo que tarda en caer la pelota resolviendo la ecuación (1) para "t":

[tex] t = \frac{v_{f}}{g} = \frac{42.43 m/s}{10 m/s^{2}} = 4.24 s [/tex]

Por lo tanto, la pelota tarda 4.24 segundos en caer.

Answers

Answer:

apples falling from trees people's feet touching the ground sky divers moving toward the ground  balls bending downward after being thrown​

Explanation:

When a space ship is accelerating in space, there is a force known as Inertia that kicks in. Inertia will mirror the effects of gravity on the ship even if there is no gravitational field effect such that anything that would happen where there is gravity, would continue to happen.

This means that apples will fall from trees, people's feet will touch the ground, sky divers will be pulled downwards and balls will bend downwards when thrown as well. These are the same effects expected on earth where gravity pulls things towards the earth's core.

B,C,D,E

Why does an aircraft carrier float

Answers

Answer:

1) Buoyant force, 2) sinks, 3) equilibrium, 4) fleet , 5) LIFT force

Explanation:

A body in a fluid is subjected to two forces, its weight and the thrust

           sun F = B - W

the em

bid is always vertical and contrary to weight, let's analyze and complete the different situations presented

1) Buoyant force

2) sinks           B <W

3) equilibrium B = W

4) fleet             B> W

5) by the sum of two forces:

* Thrust, but the density of air is much less than the density of water, therefore the thrust in the air is less.

* The other force in airplanes the lift force given by the difference in the path of the air when the plane moves, which translates into a pressure difference between the upper part of the wing and the lower part, it is force is called   LIFT force

When a certain metal is illuminated with light of frequency 2.9 ✕ 1015 Hz, a stopping potential of 7.0 V is required to stop the most energetic ejected electrons. What is the work function of this metal?

Answers

Answer:

4.96 eV

Explanation:

Recall the Einstein photoeletric equation;

KE = E - Wo

Where;

KE = kinetic energy of the ejected photoelectron

E= energy of the incident photon

Wo = Work function

But

KE = eV= 1.6 * 10^-19 C * 7 V /1.6 * 10^-19 C = 7 eV

E = hf/e = 6.6 * 10^-34 * 2.9 ✕ 10^15 Hz/1.6 * 10^-19

E = 11.96 eV

Hence;

Wo = E - KE

Wo = 11.96 eV - 7eV

Wo = 4.96 eV

There is a fixed voltage across a resistor, and you measure a current of c1 A. If you replace the resistor with one that has twice the resistance value, how much current will you measure? a) 0.2 A b) 0.5 A c) 0.8 A d) 1.1 A

Answers

Answer:

Option B

Explanation:

Given

The current flowing through the circuit = 1 Ampere

As we know

I is inversely proportional to resistance.

I α 1/r

or I = k/r

If the resistor "r" is replaced by any resistor "R" with resistance = 2r, then the current will be

I = 1/2 of 1 ampere

I = 0.5 Ampere

Hence, option B is correct

differences between weightlessness in space and weightlessness in earth​

Answers

Answer:

it depends on a person's own weight

Answer:

The gravity is roughly the same. The inverse square law applies to gravity and that means that being 60 miles above Earth is about the same as being on Earth. The thing is, they are going really fast in an orbit and thus falling around the Earth. The weightlessness comes from a sort of cancellation of gravity pulling them down and their going perpendicular to that force. The forces are cancelling and making them relatively “weightless”. It’s not really weightlessness but just an equilibrium reached between the two accelerations of gravity and their motion against the pull of the Earth.

If the basket ball appears orange then it can be said that it reflects orange light

Explanation:

The color of the object reflected by an object is the color which is viewed by a viewer. Hence, if the basket ball reflects the orange color light , then the ball will appear orange in color to the viewer.

The light absorbed by the object has no role in deciding the color of the object visible to a viewer.

hence, if the basket ball appears orange then it can be said that it reflects orange light.
