If the distance between two objects is increased to four times the original distance.how will that increase change the force of attraction between the object

Answers

Answer:

Gravitational force becomes sixteen times lesser. The strength of the gravitational force between two objects is dependent on their mass. Gravitational force will be weaker if the objects move further away from each other.

This was used to solve for the gravitational force,

G = gravitational constant

m = mass of the first object

M = mass of the second object

d = distance between the two objects

[G * (m*M) / 16d^2] = 1/16

1. Figure 5.20 shows a graph of displacement against time for a wave.

(a) What is meant by amplitude?

(b) Determine the period of oscillation, T. Then, calculate the frequency of oscillation.

2. Compare and contrast progressive wave and stationary wave.​

Answers

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.

How can we protect space shuttles or astronauts from space radiation in the absence of the atmospheric layer?
What is the role of gravity in maintaining the atmospheric layer around the earth ?
WILL MARK AS BRAINLIEST​

Answers

Earth's protective magnetic bubble, called the magnetosphere, deflects most solar particles, but in the absence of atmospheric layer, Polyethylene is a good shielding material because it has high hydrogen content, and hydrogen atoms are good at absorbing and dispersing radiation.

The Earth’s atmospheres are kept in place by gravity. The air near the ground is pulled on by gravity and compressed by the air higher in the sky. This causes the air near the ground to be denser and creating different layers with different qualities in which are the atmosphere.

Which car safety features absorb kinetic energy?
A. Seat belts and air bags

B. Seat belts and crumple zones

C. Seat belts, crumple zones and air bags

Answers

Answer:

C

Explanation:

Seat belts absorb kinetic energy when a car crashes because it pulls you back from falling forward given the kinetic energy (and momentum) you had before the crash.

Air bags absorb kinetic energy when a car crashes because it pushes you back from falling forward given the kinetic energy (and momentum) you had before the crash.

Crumple zones absorb kinetic energy when a car crashes because it provides a cushion when the cars crash. Kind of like dropping your phone into a pillow.

I hope this helps! :)

Answer:

C. Seat belts, crumple zones and air bags

Explanation:

All of these car safety features absorb kinetic energy, including seat belts, crumple zones and air bags.

Two closed organ pipe gives 4 beats when sounded together at 5°C. Calculate the number of beats in 35°C​

Answers

Answer:

The number of beats is 10.58 in 35°C.

Explanation:

The beat frequency is given by : f₁-f₂

At 5°C, f₁-f₂ = 4

We need to find the number of beats in 35°C​.

The frequency in a standing wave is proportional to [tex]\sqrt T[/tex].

So,

[tex]\dfrac{f_1-f_2}{f_1'-f_2'}=\dfrac{\sqrt {T}}{\sqrt{T'}}\\\\f_1'-f_2'=(f_1-f_2)\times \dfrac{\sqrt{T'}}{\sqrt{T}}\\\\f_1'-f_2'=4\times \dfrac{\sqrt{35}}{\sqrt{5}}\\\\f_1'-f_2'=10.58[/tex]

So, the number of beats is 10.58 in 35°C.

Phecda has a surface temperature of approximately 9500 K and a luminosity of 63. Identify the name of the star found on the Characteristics of Stars chart in the 2011 Edition Reference Tables for Physical Setting/Earth Science that has a surface temperature and luminosity closest to Phecda. a) Deneb b) Rigel c) Sirius d) Pollux

Answers

Answer:

Sirius

Explanation:

On the HR diagram Sirius is the closet.

c) Sirius has a surface temperature and luminosity closest to Phecda

What is surface tension and luminosity of a star ?

Surface temperature is the temperature at or near a surface. Luminosity is an absolute measure of radiated electromagnetic power (light), the radiant power emitted by a light-emitting object over time.

As it can be observed from the graph attached that Sirius have a surface temperature of about 10,000 K which can be considered as closest to 9500 K comparatively to other stars and if we see the the y coordinate of Sirius which is the luminosity representing axis , then Sirius have a value of luminosity closer to 63

hence correct answer is c)Sirius

If he jumps from the plane with a velocity of +2 ft/s and, after 7 seconds of free fall, he has a velocity of -223ft/s, what is his displacement?

Answers

Answer:

his displacement is 772.85 ft

Explanation:

Given;

initial velocity of his jump, u = 2 ft/s

final velocity of his jump, v = - 223 ft/s

time of motion, t = 7 seconds

acceleration due to gravity, g = 32.17 ft/s²

Let downward motion = positive direction

Let his displacement after 7s = Δh

Apply the following kinematic equation to determine his displacement.

[tex]v^2 = u^2 + 2g\Delta h\\\\(-223)^2 = (2)^2 + (2\times 32.17)\Delta h\\\\49,729 = 4 + 64.34\Delta h\\\\-64.34 \Delta h = 4 - 49,729\\\\-64.34 \Delta h = -49,725\\\\\Delta h = \frac{49,725}{64.34} \\\\\Delta h = 772.85 \ ft[/tex]

Therefore, his displacement is 772.85 ft

Explanation:

Convection is a mode of heat transfer in which the molecules near the heat source get heated up, expand, become less dense, and rise upwards. The cooler molecules, on the other hand, sink to the bottom and are eventually heated up. Thus the transmission of heat by the movement of heated particles is called convection.

The speed of light in vinegar is 2.30 x 10^8 m/s. Determine the index of refraction. (2​

Answers

Answer:

[tex]n _{v} = \frac{c}{v} \\ = \frac{3 \times {10}^{8} }{2.30 \times {10}^{8} } \\ = 1.30[/tex]

This question involves the concept of refractive index.

The refractive index of the vinegar is "1.3".

What is the Refractive Index?

The refractive index is defined as the ratio of the speed of light in air and the speed of light in the given medium which is vinegar here.

[tex]\eta = \frac{c}{v}[/tex]

where,

[tex]\eta[/tex] = refractive index = ?c = speed of light in air = 3 x 10⁸ m/sv = speed of light in vinegar = 2.3 x 10⁸ m/s
