Answer:
Explanation:
The radius of the smaller bubble, r1 will decrease and that of the bigger bubble, r2 will increase.
The pressure that is present in the smaller bubble usually is greater than the pressure that exists inside that of the bigger bubble. This then makes air to flow from r1 to r2 thereby making the radius of the smaller bubble r1, to decrease while keeping that of the bigger bubble r2 higher.

A ball is kicked straight up from the ground with a speed of 10.0 m/s. How long will the
ball be in the air?
The total amount of time the ball would be in the air is 2.04 secs
To determine how long the ball will be in the air,
We will the equation for calculating total time of flight, T
For a projectile motion, the total time of flight of an object is given by
[tex]T = \frac{2usin\theta}{g}[/tex]
Where T is the total time of flight
u is the velocity of projection
θ is the angle of projection
and g is the acceleration due to gravity
From the question,
u = 10.0 m/s
θ = 90° (This is because the ball is kicked straight up)
Put these values into the equation,
[tex]T = \frac{2usin\theta}{g}[/tex]
[tex]T = \frac{2\times 10.0 \ sin90}{9.8}[/tex]
(NOTE: g = 9.8 m/s²)
∴ [tex]T = \frac{2\times 10.0 \times 1}{9.8}[/tex]
[tex]T = \frac{20}{9.8}[/tex]
T = 2.04 secs
Hence, the total amount of time the ball would be in the air is 2.04 secs

3. Pandemic took its toll on our health. We cannot go outside to do our physical activities and socialize with other people like we used to. To maintain our active lifestyle even in the comforts of our home, we must do balanced activities. This will help us take good care of ourselves and help us cope with what is happening around us. We can identify the tasks we do at home as work, or no work done.
● On the table below, list down the personal care and school work-related activities you do at home. Classify if it has work or no work done. Furthermore, identify the form of energy while you are doing the task.

Explanation:
We know ,
F = maF = 0.2 * 2 NF = 0.4NHow is an apple falling from a tree like the potential difference in a battery?
The gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object
The gravitational potential energy of a falling apple is maximum when the apple is at maximum height. As the apple begins fall to the ground the potential energy decreases and it will be transformed to kinetic energy.
[tex]P.E_i + K.E_i = P.E_f + K.E_f[/tex]
The potential difference in a battery is total energy stored in the battery.
Thus, the gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object.
Learn more about gravitational potential energy here: https://brainly.com/question/12314347
The similarity is that both the battery and the falling apple have stored energy.
We define the potential energy of an object as stored energy in that object.
A battery has potential energy, it is stored until you connect it to something and allow that energy to flow.
Similarly, when the apple is in the air it has potential energy, that will be transformed into kinetic energy as it falls (as the apple falls, its velocity increases, thus, the kinetic energy increases).
So both, the apple and the battery have stored energy, and that is the similarity between these two.

A man is pulling a cart to the left with a force of 60 N. A second man is pushing the cart to the left with a force of 30 N. There is a force of 90 N acting on the cart in the opposite direction. What is the net force acting on the cart AND how can the motion of the cart be described?
This cart would move with constant velocity or be at rest because the net force is equal to zero (0), which means the three (3) forces acting on the cart opposes each other.
Let the first force be A. Let the second force be B.Let the third force be C.Given the following data:
Force A = 60 Newton, to the left.Force B = 2 Newton, to the left.Force C = 90 Newton, to the right.To find the net force acting on the cart:
A net force can be defined as the vector sum of all the forces that are acting on a physical object or body.
This ultimately implies that, a net force is a single (one) force that substitutes the effect of all the forces acting on a physical object or body.
Mathematically, net force is given by the following:
[tex]Net \;force = F_1 + F_2 + F_3 + F_4 + .....F_n[/tex]
Where:
F represents each force.[tex]Net\; force = 60 + 30 + (-90)\\\\Net\; force = 90 - 90[/tex]
Net force = 0 Newton
Based on Newton's First Law of Motion, this cart would move with constant velocity or be at rest because the net force is equal to zero (0), which means the three (3) forces acting on the cart opposes each other.

Answer:
Chemical changes occur when a substance combines with another to form
Explanation:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
Think about the reasons behind the cost of the Birkin bag and explain why it costs $60,000 in your own words. Do you think that this is a good marketing strategy? Why? Can you think of any other products (clothes / elctronics / anything) that use the same strategy? Does it work?
Answer:
In terms of both price and availability, the Birkin bag is as elusive as it is exclusive. For more than two decades, the bag has been the most sought item in the handbag industry. For such a modest bag, that's a lot of staying power (in looks alone, the design itself takes some 18 hours and is done by a single craftsman).
Of course, it's likely that the bag's rarity is what keeps it at the top of every want list. It is difficult, for example, to stroll into a Hermès store and buy a bag –– even if you could afford to pay the minimum price of $10,000. No, you have to be on an elite list to receive a Birkin.
Explanation:
There are alot more things like the Birkin Bag that use the same marketing skills and it works for alot of companies.

$₽﷼£❤☺wkhisrjcoycfivyudgif a 5,000 investment earn $1,575 interest over over 18 years what is the annual interest rate
Answer:
I = 1575 / 5000 = 31.5 % interest on investment
(1 + i)^18 = 1.315 where i interest is earned per year
One can use logs or
1 + i = 1.315^1/18 = 1.0153
So the annual interest rate is .0153 or 1.53%
Or
5000 (1 + i)^18 = 6575
(1 + i)^18 = 1.315
18 log (1 + i) = log 1.315
log (1 + i) = .006607
1 + i = 1.0153
i = .0153 = 1.53%
