Consider two samples of gas. Sample A consists of n moles and is kept at temperature T in container of volume V. Gas B consists of 2n moles, and is kept under the temperature T/2 in a container of volume V/2. What is the pressure of gas B in terms of pressure of gas A, P?
a. 2P
b. 4P
c. 8P
d. P
e. P/2
f. P/4
g. P/8
Answer: e. P/2
Explanation:
For ideal gases, we have the relation:
P*V = n*R*T
where:
n = number of mols
R = Gas constant
T = temperature
V = volume
P = pressure.
We know that for sample A, we have n moles, a temperature T and a volume V, then the pressure of this sample will be:
Pa = (n*R*T)/V.
For sample B, we have:
n/2 moles, temperature T/2 and a volume V/2, then the pressure will be:
Pb = (n/2)*R*(T/2)*(2/V) = (n*R*T/V)*(2/4)
and:
(n*R*T/V) = Pa
Then we can replace it and we get:
Pb = (n*R*T/V)*(2/4) = Pa*(2/4) = Pa*(1/2) = Pa/2.
Then the correct option is e.

The amount of work required for a
dump truck to move a mound of dirt 0
meters using a force of 70 Newtons is
what?
Answer:
0 (zero) Joules
Explanation:
If the displacement is 0 (zero) meters, then the work is zero, since it is defined as the product of the force exerted times the displacement that occurred in the same direction of the force.
If the displacement is zero, the product becomes zero as well.
On 16th August 2020, an asteroid (later called 2020 QG) has been recorded as the closest
asteroid (spotted so far) that flew by the Earth without colliding with it. At the nearest point
of approach, it was only 2 950 km above Earth’s surface and it had a velocity v = 12.3 km·s
−1
.
How much higher was its velocity compared to the escape velocity at that height above Earth’s
surface? Find the ratio v/vesc.
Answer:
V/Ve = 1.1
Explanation:
The formula to find the escape velocity of an object at a distance from Earth's Surface is given as follows:
Ve = √[2GM/R]
where,
Ve = escape velocity = ?
G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²
M = Mass of Earth = 5.97 x 10²⁴ kg
R = Radius of Earth = 6.37 x 10⁶ m
Therefore,
Ve = √[2(6.67 x 10⁻¹¹ N.m²/kg²)(5.97 x 10²⁴ kg)/(6.37 x 10⁶ m)]
Ve = 11.2 x 10³ m/s = 11.2 km/s
Hence, the ratio will be:
V/Ve = (12.3 km/s)/(11.2 km/s)
V/Ve = 1.1

An object starts from rest at the origin and moves along the x axis with a constant
acceleration of 4 m/s
2
. Its average velocity as it goes from x = 2 m to x = 8 m is:
Answer:
6.9m/s
Explanation:
Given parameters:
Acceleration of the object = 4m/s²
Distance = from x; 2m to x; 8m
Unknown:
Average velocity = ?
Solution:
From the given parameters, we use the right motion equation to solve the problem.
v² = u² + 2aS
v is the final velocity
u is the initial velocity
a is the acceleration
S is the distance covered
Distance = 8m - 2m = 6m
Initial velocity = 0m/s
The final velocity gives us the average velocity in this problem;
v² = 0² + (2 x 4 x 6) = 48
v = √48 = 6.9m/s

It is said that Galileo dropped objects off of the Leaning Tower of Pisa to determine whether heavy or light objects fall faster. If Galileo had dropped a 5 kg cannonball from a height of 12 meters,
Answer:
ΔP.E = - 588 J
Explanation:
The complete question is as follows:
It is said that Galileo dropped objects off the Leaning Tower of Pisa to determine whether heavy or light objects fall faster. If Galileo had dropped a 5.0-kg cannon ball to the ground from a height of 12 m, what would have been the change in PE of the cannon ball?
Answer: So, in order to calculate the change in Potential Energy of the cannon ball, we will use the general formula of Potential Energy as follows:
ΔP.E = mgΔh
where,
ΔP.E = Change in Potential Energy = ?
m = mass of cannon ball = 5 kg
g = acceleration due to gravity = 9.8 m/s²
Δh = Change in Height of Cannon Ball = Final Height - Initial Height
Δh = 0 m - 12 m = - 12 m
Therefore,
ΔP.E = (5 kg)(9.8 m/s²)(- 12 m)
ΔP.E = - 588 J
Negative sign shows decrease in Potential Energy
What is the change in momentum of a 4 kg object accelerating from 10 m/s to 12 m/s? In this problem what is the change in velocity
Answer:
8 kg*m/s and 2m/s
Explanation:
momentum is mass times velocity. since the velocity changes by 2 m/s. you just take the difference from final velocity to beginning velocity.
4kg*12m/s = 48 kg*m/s
4kg*10m/s = 40 kg*m/s
48kg*m/s - 40 kg*m/s = 8kg*m/s

Which force is a noncontact force?
(15 points)
A.
magnetic force
B.
frictional force
C.
normal force
D.
impact force
Answer:
Magnetism is an example of a non-contact or action-at-a-distance force. These are forces which can act on an object without being in physical contact with it. The force of gravity is another example. Thus, gravity will pull a raindrop down to Earth without any tangible physical link between the Earth and the drop.
Explanation:
hope this helps u, sorry if it doesn't.
Answer:
Magnetic force
Explanation:
It would be this because all of th other forces are touching the object to make it move or somhting like that, the only one that makes it move by not touching it would be the magnetic force,
Hope this helps
A ball of mass 2 kg is moving with a speed of +6 m/s directly towards
another ball of mass 1 kg moving with a speed of -4 m/s. If they collide
inelastically, what will be the speed of the resulting 3 kg ball
immediately after the collision?
Answer: 2.7
Explanation:
A 2.5 kg object has an acceleration of 4 m/s2. What is the force of the object?
Force = Mass × Acceleration
Mass = 2.5 kg
Acceleration = 4 m/s^2
Force = 2.5 × 4
Force = 10 N
The force of the object is 10 N

What happens to a copper wire when it is moved across a magnetic field?
A. Voltage and electric current are induced
B. It’s attracted to the positive pole of magnetic field
C. Electric current is induced, but not voltage.
D. It’s attracted to negative pole of magnetic field
Answer:
it is attracted to negative pole
A copper wire will get attracted to negative pole of magnetic field when it
is moved across it
The copper wire has free electrons in it which when moved across the
magnetic field will result in the movement of the electrons to the negative
pole of the magnetic field.
This is because unlike poles attract and like poles repel. Copper is a metal
and positively charged and so it gets attracted to the negative pole during
electron flow.

When forces in a system are in balance there is
Answer:
Equilibrium
Explanation:
When forces in a system are in balance, there is equilibrium.
A balance of forces around a system causes equilibrium of a system.
A body will remain its state of rest or continue in uniform motion unless acted upon by an external force. This balance of forces on a body keeps a body at rest. Even in motion, the body is at rest unless an external force acts on it.The weight of an object can be determined by multiplying the mass of the object by which of the following?
