Answer:
Twice its original volume.
Explanation:
For diving applications, 10 m/33 feet of sea water is taken to exerts a gauge pressure that is the same pressure as the atmosphere, or one ata/bar.
This means that we add one ata/bar pressure for every 10 m/33 feet you descend.
The effect of this is that, at 10 m/33 ft, you're under an absolute pressure of two ata/bar, one from air and one from water. Adding another 10 m/33 ft to this depth to make it 20 m/66 ft, puts you under under three ata/bar of pressure and so on.
Descending to a depth of 10 m/33 ft, with a flexible container means that you have double the ata/bar pressure acting on you. If you decide to resurface, the pressure on the flexible container will reduce by a factor of two.
Since volume is inversely proportional to the pressure, if the pressure reduces by a factor of 2, then the volume will increase by a factor of two, or we can say that the volume will double.

A rock is thrown upward with a velocity of 14 meters per second from the top of a 25 meter high cliff, and it misses the cliff on the way back down. When will the rock be 3 meters from ground level? Round your answer to two decimal places.
Answer:
It takes the rock t = 3.98 seconds to reach 3 meters from ground level
Explanation:
We need to set the kinematic equation for the vertical position of this motion in one direction with the zero (reference level) at ground level. So, the initial position of the rock is at positive 25 meters, and we need to find the time it takes to reach positive 3 meters.
Recall as well that the only acting acceleration is that due to gravity (g = 9.8 m/s^2) opposed to the object's initial velocity (Vi = 14 m/s). Then the position equation becomes:
[tex]y_f=y_i+v_i\,t-\frac{1}{2} \,9.8 \,t^2\\3 = 25 + 14\,t-4.9\,t^2\\4.9\,t^2-14\,t-22=0[/tex]
and we need to solve for "t" using the quadratic formula:
[tex]t=\frac{14+/-\sqrt{(-14)^2-4\,(4.9)(-22)} }{9.8} \\t=3.984 \,\,\,\, or\,\,\,\, t=-1.127[/tex]
Since we are looking for a positive value for time, starting when the rock is launched, we select the positive answer, which should come in seconds:
t = 3.98 seconds
(rounded to two decimals as requested)
Answer:
It takes the rock t = 3.98 seconds to reach 3 meters from ground level

Technician A says that LCDs may be slow to work at low temperatures. Technician B says that an LCD dash display can be damaged if pressure is exerted on the front of the display during cleaning. Which technician is correct?
Answer:
technician B is right
Explanation:
A liquid crystal screen works by the polarization of the molecules that make up the screen by a local electric field, to abalone there must be a light source in the traces pattern in such a way that when a part of the screen is polarized the light manages to come out and we see the image. The polarization of the liquid crystal is a very fast process, therefore Technician A's comment is incorrect.
Liquid crystal displays (LCDs) are generally small and excessive pressure can break the glass and damage the display.
From the previous clarifications, technician B is right

A remote controlled car starts from rest and accelerates at 2 m/s² for 6.5 seconds. What is the final velocity of the car after the acceleration takes place?
Answer:
The final velocity of the car after the acceleration takes place is 13 m/s.
Explanation:
The final velocity can be calculated using the following equation:
[tex] V_{f} = V_{0} + at [/tex]
Where:
[tex]V_{0}[/tex]: is the initial velocity = 0 (starts from rest)
a: is the acceleration = 2 m/s²
t: is the time = 6.5 s
Hence, the final velocity is:
[tex] V_{f} = V_{0} + at = 0 + 2 m/s^{2}*6.5 s = 13 m/s [/tex]
Therefore, the final velocity of the car after the acceleration takes place is 13 m/s.

Which statement is true about a person who is in good health? She spends a lot of time alone She has few friends at school She may not be in good physical health She gets along with others
Explanation:
Engaging in social and productive activities you enjoy, like taking an art class or becoming a volunteer in your community, may help to maintain your well-being.
Research tells us that older people with an active lifestyle:
Are less likely to develop certain diseases. Participating in hobbies and other social and leisure pursuits may lower risk for developing some health problems, including dementia.
Have a longer lifespan. One study showed that older adults who reported taking part in social activities (such as playing games, belonging to social groups, or traveling) or meaningful, productive activities (such as having a paid or unpaid job, or gardening) lived longer than people who did not. Researchers are further exploring this connection.
Are happier and less depressed. Studies suggest that older adults who participate in what they believe are meaningful activities, like volunteering in their communities, say they feel happier and healthier. One study placed older adults from an urban community in their neighborhood public elementary schools to tutor children 15 hours a week. Volunteers reported personal satisfaction from the experience. The researchers found it improved the volunteers’ cognitive and physical health, as well as the children’s school success. Researchers think it might also have long-term benefits, lowering the older adults’ risk of developing disability, dependency, and dementia in later life.
Are better prepared to cope with loss. Studies suggest that volunteering can help with stress and depression from the death of a spouse or other loved one. Among people who experienced a loss, those who took part in volunteer activities felt more positive about their own abilities (reported greater self-efficacy).
May be able to improve their thinking abilities. Another line of research is exploring how participating in creative arts might help people age well. For example, studies have shown that older adults’ memory, comprehension, creativity, and problem-solving abilities improved after an intensive, 4-week (8-session) acting course. Other studies are providing new information about ways that creative activities like music or dance can help older adults.
A fuel-filled rocket is at rest. It burns its fuel and expels hot gas. The gas has a momentum of 1,500 kg x m/s backward. What is the
momentum of the rocket?
a
0
b
-1,500 kg x m/s forward
1,500 kg x m/s forward
с
Answer:
a
Explanation:
Its mass times m/s there is no m/s so 1500x0 = 0
This question involves the concept of the law of conservation of momentum.
The momentum of the rocket is "c 1,500 kg x m/s forward"
The law of conservation of momentum states that the total momentum of the system must be constant. It means that the change in momentum of the system must be equal to zero. Here the system is the rocket and the gases. So, applying the law of conservation of momentum to this system, we get:
Momentum of Gas + Momentum of Rocket = 0
Taking, forward direction as positive and the backward direction as negative:
[tex]- 1500\ kg.m/s+Momentum\ of\ Rocket = 0\\[/tex]
Momentum of Rocket = 1500 kg.m/s (forward)

of 24 ohms?
1.)48V
2.)6.0V
3.)24V
4.)12V
Answer:
4.)12V
Explanation:
The voltage of 12 volts is needed cause a current of 0.5 ampere in a circuit that has a resistance of 24 ohms.
We have a current of 0.5 Ampere in a circuit that has a resistance of 24 ohms.
We have to determine what voltage would cause this current.
What is Ohm's law?According to Ohm's law, the current flowing in the conductor is directly proportional to the voltage across the conductor, provided all physical conditions and temperature remain constant. Mathematically -
V = IR
According to the question, we have -
Current (I) = 0.5 A
Resistance (R) = 24 ohms
Using Ohm's law -
V = IR
V = 0.5 x 24 = 12 volts
Hence, the voltage of 12 volts is needed cause a current of 0.5 ampere in a circuit that has a resistance of 24 ohms.
