Answer:
It will be more
Explanation:
Pressure and volume relationships between gases is given by the Boyle's law.
According to this law, we know that:
"the volume of a fixed mass of a gas varies inversely as the pressure changes if the the temperature is constant".
So, the higher the pressure on a body, the lower it's volume and vice versa.
Since we set off at a higher pressure and wants to end at a lower pressure, the volume of the gas will increase more.

Go to your backyard or to your high school’s basketball court or tennis court and try out this experiment to see if you can predict motion and inertia accurately. Bring a friend or classmate. Take along a ball.
Select two spots roughly 10 meters apart. Mark each of them clearly. The first spot will be the starting point and the second will be the target.
Ask a friend to run as fast as possible (sprint) carrying the ball from the starting point to the target. Have your friend release the ball when he or she is immediately over the target trying NOT to swing arms when dropping the ball.
Record the results in the table below.
Repeat the sprint at least five times. Record where the ball lands each time.
Next, ask your friend to jog to the target with the ball and drop it. In the table, again record where the ball lands. Do two trials.
For the final test, ask your friend to walk to the target and drop the ball. Also record these results in the table. Do two trials

(b) The cabin and passengers have a total mass of 800 kg. The vertical distance between
B and C is 50 m.
Calculate the increase of gravitational potential energy of the cabin and passengers when they
move from B to C.
energy =
Answer:
392 kJ
Explanation:
Given that,
The total mass of the cabin and the passengers = 800 kg
The vertical distance between B and C is 50 m.
We need to find the increase of gravitational potential energy of the cabin and passengers when they move from B to C. It can be given by the relation as follows :
[tex]E=mgh\\\\E=800\times 9.8\times 50\\\\E=392000\ J\\\\\text{or}\\\\E=392\ kJ[/tex]
So, the increase in gravitational potential energy is 392 kJ.

What should be the initial potential energy of a pile driver ram so that when it strikes piles, it delivers a kinetic energy of 20 KJ?
Answer:
the initial potential energy should be 20 kJ.
Explanation:
Based on law of conservation of energy, the kinetic energy delivered by the pile driver when it strikes the piles, should be equal to the initial potential energy.
Since the final kinetic delivered is given as 20 kJ, then the initial potential energy should be 20 kJ.
Therefore, the initial potential energy should be 20 kJ.
Sue played four games of golf the modal score was 98 and the mean 100 and the range 10 What were the scores for the games
Answer:
Explanation:
Let the highest and lowest score be a and b respectively .
a - b = 10
a = 10 + b
The numbers in descending order are a , 98 , 98 , b .
mean = 100 , so
4 x 100 = a + 98 + 98 + b = 10 + b + 98 + 98 + b = 206 + 2b
400 = 206 + 2b
2b = 194
b = 97
a = 107
So the scores were as follows
107 , 98 , 98 , 97

A force of 6.0 N is applied horizontally to a 3.0 kg crate initially at rest on a horizontal frictionless surface. After the crate is pushed for 1.5 seconds, it has a velocity of 3.0 m/s. Does this support Newton's second law of motion, that force equals mass times acceleration? Explain. 
a. Yes, because the acceleration of the crate is 2.0 m/s².
b. No, because the acceleration of the crate is 2.0 m/s².
c. Yes, because the mass and the velocity of the crate are equal.
d. No, because the mass and the velocity of the crate are equal.
Answer:
a. Yes, because the acceleration of the crate is 2.0 m/s².
Explanation:
Given
[tex]Force = 6N[/tex] --- f
[tex]Mass = 3kg[/tex] --- m
[tex]Time = 1.5s[/tex] --- t
[tex]Velocity = 3.0m/s[/tex] --- v
Required
Does the system support [tex]F=ma[/tex]
Yes, it does and this is shown below
The crate is initially at rest; so:
[tex]u = 0[/tex]
Using the first equation of motion
[tex]v = u + at[/tex]
Substitute values for v, u and t
[tex]3 = 0 + a*1.5[/tex]
[tex]3 = 1.5a[/tex]
Make a the subject
[tex]a = 3/1.5[/tex]
[tex]a = 2[/tex]
Using [tex]F = ma[/tex]
Substitute values for F and m
[tex]6 = 3 * a[/tex]
Divide both sides by 3
[tex]6/3 = 3/3 * a[/tex]
[tex]2 = a[/tex]
[tex]a = 2[/tex]
In both cases:
[tex]a = 2[/tex]
Hence, option (a) is correct.

What is the unit of a force, and what is 1 unit equivalent to?
Answer:
Newton
Explanation:
The unit of force is Newton and it is given after Sir Isaac Newton for his tremendous works in this regard.
Force is the product of mass and acceleration of a body.
Force = mass x acceleration
The unit of mass = kg
acceleration = m/s²
So;
1N = 1kgm/s²
Therefore, the unit of force is newtons and 1N is equal to 1kgm/s²

Which part of this chemical process requires energy? KOH + HBr - KBr + H20 A. Forming bonds in KOH and HBr B. Breaking bonds in KBr and H2O C. Breaking bonds in KOH and HBr D. Forming bonds in KBr and H2O
The chemical process which requires energy is breaking bond in KOH and HBr. Hence, option C is correct.
What is energy?The capacity to perform work is known as energy in physics. Potential, kinematic, thermodynamic, electromagnetic, chemical, nuclear, and other types are all possible.
As energy is transferred through one body to another, there is also heat and work. As a result, heat transfer may result in thermal energy, whereas labor done may result in mechanical power.
As per the given reaction in the question,
KOH + HBr - KBr + H20
Here, in this reaction the chemical process which requires the energy is at the time of breaking of bonds in KOH and HBr at that time the energy is required.
Therefore, it is concluded that breaking bonds in KOH and HBr i.e., option C is correct.

Calculate the resistance of an electric blanket that draws 9 A to transform 50 W of energy.
Answer:
The resistance is 0.617Ω.
Explanation:
Given that the formulas are V = I × R and P = I × V so when you substitute the V formula into P formula, you will get P = I² × R. Using this formula, you can find the resistance :
P = I² × R
50 = 9² × R
50 = 81 R
50 ÷ 81 = R
R = 0.617Ω (3sf)

How could you explain that two objects of the same volume have different buoyancy in water???
HELP ITS URGENT
Answer:
Explanation:
Take for example you place two eggs in the water. One starts to sink and one remains floating. They have the same volume but the one that sinks is cracked just a little, which as soon as it hits the water, water starts to go in the egg. Then that changes the volume of the egg. (I've done this expirement before) It can also be the way you place the object in the water, or one object has been in the water longer. The buoyancy can be the way they are positioned/placed in the water. One may be more absorbant to the water as well.
I hope you understand what I am trying to say.
