A clown hangs two balloons from either end of a hanger. The air from on balloon is released, and the hanger tilts. Which principle is illustrated? a. gas is matter, and therefore has mass b. gas has volume that is not measurable c. released gas has a higher temperature than inert gas d. matter may never be destroyed

Answers

Answer:

A.) gas is matter, and therefore has mass

Explanation:

The principle illustrated in this scenario is a. gas is matter, and therefore has mass.

When the air from one balloon is released, it creates a flow of gas in one direction. According to the principle of gas having mass, the released gas exerts a force on the hanger, causing it to tilt. This demonstrates that gas is matter and has mass.

It's important to note that gas does have volume, which can be measured. This is not the principle being illustrated in this scenario.

The principle of released gas having a higher temperature than inert gas is not applicable in this scenario, as no information is given about the temperatures of the gases involved.

The principle of matter may never be destroyed is a general principle in physics and does not specifically apply to this scenario.

Find the volume of a box with length 25 cm, height 25 cm and width 1.0 m.

Answers

Before finding the volume, it is always good to change the units as same.
length 25cm
height 25cm
width 100cm

volume
length * height * width
25 * 25 * 100

Jake drops a book out of a window from a height of 10 meters. At what velocity does the book hit the ground? Answer choices: A: 7.0Meters/Second B: 10Meters/Second C: 14Meters/Second D: 28Meters/Second

Answers

Jake drops a book out of a window from a height of 10 meters. The velocity does the book hit the ground is 14 m/s. hence option C is correct.  

What is velocity?

Velocity is defined as the pace at which an item changes position while moving in one direction, as seen from a certain point of view and as measured by a specific unit of time. Given that it has both a magnitude and a direction, velocity is a vector quantity.  Velocity measures movement that begins in one location and moves to another location.

We are aware that V=final velocity and V2-U2=2.

U is the initial velocity, and A is the acceleration, and D is the distance, therefore V=14 m/s.

Thus, Jake drops a book out of a window from a height of 10 meters. The velocity does the book hit the ground is 14 m/s. hence option C is correct.

#SPJ2

C is your answer. we know V^2-U^2=2 as where V=final velocity.
U is inital velocity
A= acc.
s= distence
a.t.q
v^2 -o^2 =(2*9.8*1o)
so, V=14 m/s

Two shoes each have a mass of 0.1 kg. if the are .15m apart what is the gravitational force between them? G = 6.67 x 10^-11 N (m/kg)^2

Answers

Formula:

F = G \cdot (m_1 m_2)/(r^2)

m1, m2 - mass  in kg
r - distance in meter.

m1 = m2 = 0.1kg
r = 15m 

F = 6.67 \cdot 10^(-11)  N \cdot (m^2)/(kg^2) \cdot (0.1 \cdot 0.1 kg^2)/(15^2 m^2) \n \n  F=(6.67 \cdot 0.01 \cdot 10^(-11))/(225) N \n \n F \approx 0.00002964 \cdot 10^(-11) N \n \n F \approx 2.96 \cdot 10^(-16) N

In stars mor massive than the sun, fusion continues until the core is almost all....

Answers

In stars more massive than the sun, the core temperature is hotter, which allows for fusion of more complex elements.

Most of the fusion occurs in the core.

In stars more massive than the sun, fusion continues through Deuterium, Carbon, and finally reaching iron/nickel.

Up to this point, the fusion reaction was endothermic, which means that the energy expended to produce the fusion reaction was exceeded by the energy produced in the reaction.

Fusion past iron is exothermic, and therefore the star will be able to survive by fusing elements heavier than iron.

After the core is almost entirely iron, the star is no longer in the Main Sequence.

So, fusion in stars more massive than the sun continue fusing until the core is almost entirely iron.
