The generation of more potent telescopes to observe the Universe made things easier/better for us to research and explore our solar system.

<h3>What are technological advances in Astronomy research?</h3>

The technological advances in Astronomy research are all those devices and strategies aimed at enhancing our ability to explore the Universe, which is represented by telescopes that generate high-resolution images.

Therefore, with this data, we can see that technological advances in Astronomy research are associated with the development of potent telescopes which facilitate the observation of other celestial bodies from the Earth.

insens350 [35]

<u>Statement</u><u>:</u>

Jane does 5 joules of work when she closes her bedroom window. She applies a force of 6 newtons to do the job.

<u>To </u><u>find </u><u>out:</u>

The displacement of the window when she pulled it.

<u>Solution</u><u>:</u>

Work done (W) = 5 J
Force (F) = 6 N
Let the displacement of the window be s.
We know, the formula of work done, i.e., W = Fs
Putting the values in the above formula, we get
5 J = 6 N × s
or, s = (5 ÷ 6) m
or, s = 0.83 m

<u>Answer</u><u>:</u>

She pulls the window by 0.83 m.

Hope you could understand.

If you have any query, feel free to ask.

A body is traveling at 5.0 m/s along the positive direction of an x axis; no net force acts on the body. An internal explosion s

loris [4]

To solve this problem it is necessary to apply the concepts related to the conservation of momentum and conservation of kinetic energy.

By definition kinetic energy is defined as

$KE = \frac{1}{2} mv^2$

Where,

m = Mass

v = Velocity

On the other hand we have the conservation of the moment, which for this case would be defined as

$m*V_i = m_1V_1+m_2V_2$

Here,

m = Total mass (8Kg at this case)

$m_1=m_2 =$ Mass each part

$V_i =$ Initial velocity

$V_2 =$ Final velocity particle 2

$V_1 =$ Final velocity particle 1

The initial kinetic energy would be given by,

$KE_i=\frac{1}{2}mv^2$

$KE_i = \frac{1}{2}8*5^2$

$KE_i = 100J$

In the end the energy increased 100J, that is,

$KE_f = KE_i KE_{increased}$

$KE_f = 100+100 = 200J$

By conservation of the moment then,

$m*V_i = m_1V_1+m_2V_2$

Replacing we have,

$(8)*5 = 4*V_1+4*V_2$

$40 = 4(V_1+V_2)$

$V_1+V_2 = 10$

$V_2 = 10-V_1$ (1)

In the final point the cinematic energy of EACH particle would be given by

$KE_f = \frac{1}{2}mv^2$

$KE_f = \frac{1}{2}4*(V_1^2+V_2^2)$

$200J=\frac{1}{2}4*(V_1^2+V_2^2)$ (2)

So we have a system of 2x2 equations

$V_2 = 10-V_1$

$200J=\frac{1}{2}4*(V_1^2+V_2^2)$

Replacing (1) in (2) and solving we have to,

200J=\frac{1}{2}4*(V_1^2+(10-V_1)^2)

PART A: $V_1 = 10m/s$

Then replacing in (1) we have that

PART B: $V_2 = 0m/s$

In what condition do acceleration and deaccelration<br>

Vera_Pavlovna [14]

Im not sure what are you asking about. But in physic/ mechanic usually when the object against gravity, its deceleration but when the object follow the gravity its acceleration

Also usually when the object move to the left side the speed will be negative (-) this is probably because of deceleration? since deceleration = -acceleration.
