a spaceship, at rest in a certain reference frame s, is given a speed increment of 0.500c. it is then given a further 0.500c increment in this new frame, and this process is continued until its speed with respect to its original frame s exceeds 0.999c. how many increments does it require?

Answers

In order to give a spaceship at rest in a specific reference frame s a speed increment of 0.500c, seven increments are required. Then, in this new frame, it receives an additional 0.500c increment.

The speed of an object, also known as v in kinematics, is a scalar quantity that refers to the size of the change in that object's position over time or the size of the change in that object's position per unit of time. The distance travelled by an object in a certain period of time divided by the length of the period gives the object's average speed in that period.

The spacecraft moves at v1 = 0.5c after the initial increment.The equation becomes V2 = V+V1/1+V*V1/c after the second one. 2 V2 = 0.5c+0.50c/1+(0.50c)^2/c^ 2 = 0.80c

Likewise, V3 = 0.929c

V4 = 0.976c

V5 = 0.992c

V6 = 0.99c

V7 = 0.999c

If 104 w/m2 corresponds to 160 db, what is the sound intensity level, in decibels, of ultrasound with intensity 105 w/m2, used to pulverize tissue during surgery?.

Answers

The ultrasound with intensity  10⁵ W/m², used to pulverize tissue during surgery, has the sound intensity level of 170 decibels.

The relation between sound intensity and sound intensity level is given by:

β (dB) = 10 x log(I/Io)

Where:

β = sound intensity level in decibels (dB)

I = sound intensity

Io = reference intensity

In the given problem:

β = 160 dB if I = 10⁴ W/m²

Find the reference intensity:

β = 10 x log(I/Io)

160 = 10 x log (10⁴ /Io)

log (10⁴ /Io) = 16

Io = 10⁻¹²

Use Io = 10⁻¹² to calculate the sound intensity level of  10⁵ W/m² sound intensity.

β = 10 x log(10⁵/10⁻¹²)

β = 10 x log(10¹⁷)

  = 170 dB

Hence, the sound intensity level is 170 dB

In all of the following, with the exception of, degeneracy pressure is the source of the pressure that prevents the crush of gravity. The correct option is D) a very massive main-sequence star.

With the exception of stellar evolution, degeneracy pressure is the cause of the pressure that prevents gravity's crush in all of the instances below. Tiny, relatively chilly, minimal-mass red dwarfs fuse hydrogen over the course of trillions of years or more while remaining on the main sequence.Red dwarfs smaller than 0.35 M are entirely convective, according to stellar simulations. The helium produced by the thermonuclear fusion of hydrogen is thus continuously remixed throughout the star, preventing the buildup of helium at the core and lengthening the fusion period.

A 3-kg mass attached to a string which goes vertically to a pulley rests on the floor. A weight is attached to the other end and released. If the 3-kg mass rises 50 cm in 1. 0 s, what is the mass of the weight?.

Answers

A weight is attached to the other end of the pulley and released, resulting in 3-kg mass to rise 50 cm in 1.0 s.  The mass of the weight is 3.68 kg

The problem can be solved using the equation of motion:

s = u . t + 1/2 a . t²

Where:

s = distance

u = initial velocity

t = time period

a = acceleration

Substitute the given parameters:

s = 50 cm = 0.5 m

u = 0

t = 1

Hence,

0.5 = 0 + 1/2 a . 1²

1/2 a = 0.5

a = 1 m/s²

After obtaining the acceleration, a, use the Newton's 2nd law of motion.

Forces acting on mass 3 kg : tension (T), weight (mg).

Hence,

T - mg = ma

T = m (g + a)

Let M = mass of the weight.

Forces acting on M : tension (T), weight (Mg). Hence,

Mg - T = Ma  

T = M (g - a)    (substitute T = m (g + a) )

m (g + a) = M (g - a)

M = m x (g + a) / (g - a)

Answers

Both people will have to apply a force equal to 5150N.

This problem can be solved using Newton's Second Law of Motion which states that the force applied on any particle is equal to the product of mass and acceleration of the particle. The expression can be written as

F = ma ; where 'm' is the mass of particle and 'a' is the acceleration of particle.

Now, m = 2000 kg and a = 5 m/s²

F = 2000 kg × 5 m/s²

F = 10000 N

Now, the friction force will be added to this required force. Because to get the car starting to move, the friction force first needs to be overcome.

Total force = F + Frictional force

Total force = 10000 N + 300 N

Total force = 10300 N

What is motion?

Motion is a change in position of an object over time. It occurs when an object moves from one point to another. Motion can be described in terms of displacement, distance, speed, velocity, and acceleration. Motion can also be described using Newton's laws of motion which state that an object in motion will remain in motion unless acted upon by an external force. Motion also describes the motion of particles in a fluid or gas, as well as the motion of waves in a medium. Motion is an essential part of the physical world and is essential for understanding the fundamental laws of nature.

Motion in a straight line

Let,

u = Initial velocity of stone

H = Maximum height attained by the stone

v = final velocity at maximum height = 0

t = time taken to attain maximum height = 3s

a=−g= acceleration due to gravity

a. We know that,

V=u+at

0=u−g×3

U=3g=3×9.8ms−2

U=29.4ms−1

b. From the equations of motion, we know that,

S=ut+ ½ a t2

H=29.4×3+½ * 9.8 *32

H=88.2+44.1

H=132.3m

What group(s) of elements on the periodic table really want to give away an electron? why?.

Answers

The groups in the periodic table that really want to give away electrons are groups IA, IIA, and some groups IIIA. The members of these groups are mostly metals.

Metals elements

Metals elements have relatively small ionization energies and electron affinities, so they easily give away electrons and are difficult to accept. Whereas non-metallic atoms have large ionization energies and electron affinities, non-metallic atoms easily accept electrons but find it difficult to release electrons.

Ionization energy is the energy required to remove the outer electrons of an atom in the gaseous state. A small ionization energy value indicates that the atom easily releases electrons and if the ionization energy is large, it is difficult for the atom to release electrons.

So, metal atoms tend to give away electrons because they have a small ionization energy, while non-metal atoms tend to gain electrons because they have a high electron affinity.

while the astronaut is near the black hole for what it seems to her like an hour, how much time passes on the spaceship?

Answers

For a black hole observer, one hour is equivalent to 100,000,000 years on Earth.

In contrast to time distant from a black hole, time moves more slowly as you approach closer to one. (According to Einstein's theory, this effect is produced by any big body, including the Earth. Because of how weak Earth's gravity is, the impact of time slowing has been seen and verified by sensitive devices. For instance, if you lived on the summit of Mount Everest, you would age one billionth of a second faster than you do at sea level.) The tremendous slowing of time is seen close to a black hole. Time is stopped from the perspective of an observer outside the black hole. The border of the hole, for instance, would seem to be frozen in time while an item fell into it.

if distance of travel increases and time remains same what happens to the speed​

Answers

Answer: By increasing speed over a fixed period of time, you increase

the distance you travel in that period of time. If you drive 20 mph

for an hour, you go 20 miles. If you drive 30 mph for that same

hour, you go 30 miles. Just like you knew you would.
