First the ideal gas law will be used to solve for the moles of unknown gas (n).
What is the mass of this unknown gas?
The unit that is used to measure the molar mass is grams per moles (g/mol). The mass of gas in a one-mole sample is equal to the molar mass of gas. If the molar mass of gas X was 40 g/mol, this means that the weight of gas X in a one-mole sample is equal to 40 grams.An ideal gas is considered to be a "point mass". A point mass is a particle so small, its mass is very nearly zero. This means an ideal gas particle has virtually no volume.Matter is anything that occupies space and has mass. Gas is one of the states of matter, hence, gases also have mass.According to Boyle's law, for a fixed mass of gas, at the constant temperature, the volume is inversely proportional to its pressure. According to Avogadro's law, the volume of a gas is directly proportional to the number of molecules at constant temperature and pressure.To learn more about mass refers to:

Because his weight is distributed evenly over both scales, the reading on each scale should be 400 N. This is the first option.
Weight, symbolized as W, is a type of force whose acceleration is defined as the acceleration due to gravity. This is why weight is also called the force of gravity (Fg). Weight is not the same as mass. Weight is force, but mass is the measure of the inertia of a body.
The equation for weight is W = mg, where W is weight, m is mass, and g is acceleration due to gravity.
When the man stands, at rest, on two bathroom scales, his weight is then distributed evenly over the scales. This causes the reading on each scale to be half his actual weight.

Explanation:
starting from rest at home plate, a baseball player runs to first base 90 feet away. he uniformly accelerates over the first 10 feet to his maximum speed vmax, which is then maintained until he crosses first base. if the overall run is completed in 4 seconds, determine his maximum speed and the time duration of the acceleration.
His maximum speed is 25 ft/sec, and the time duration of the acceleration is 0.8 Sec.
Let, maximum speed is V and acceleration is a (See Picture).
Total time given = 4 secs.
Total time = Time required to accelerate(t) + Time at constant maximum speed(T)
Total time = (t+T)
T+t = 4_______________(1)
Given,
Total distance (D) = 90 ft.
We know,
[tex]V^{2} = 2as[/tex]
⇒ [tex]s = \frac{V^{2} }{2a}[/tex]
Given, s = displacement = 10 ft
⇒ [tex]\frac{V^{2} }{2a} = 10[/tex] ___________________(2)
Now We know,
Speed = final distance / Time at constant maximum speed(T)
⇒ [tex]V=\frac{D-s}{T}[/tex]
⇒ [tex]V = \frac{90-10}{4-t}[/tex]______________[By (1)]
⇒ [tex](4-t) V= 80[/tex]_______________(3)
Also, We know,
[tex]V= u+at[/tex]
But, here u (initial velocity) = 0
∵ [tex]V=at[/tex] ____________________(4)
Now, solving (2), (3) and (4) we get,
[tex](4-t)V+\frac{V^{2} }{2a} = 90[/tex]_______[Adding (2) & (3)]
⇒ [tex]4V-\frac{V^{2} }{a} + \frac{V^{2} }{2a} =90[/tex]________[By (4)]
⇒ [tex]4V-\frac{V^{2} }{2a} =90[/tex]
⇒ [tex]4V-10=90[/tex]_______[By (2)]
⇒ [tex]4V= 100[/tex]
⇒ [tex]V = 25[/tex] ft/sec.
putting the value of V in (2)
We get,
[tex]10=\frac{625}{2a}[/tex]
⇒ [tex]a = \frac{625}{20}[/tex]
⇒ [tex]a = 31.25 ft/sec^{2}[/tex]
Now, putting the values of V and a in (4)

A 0.14 kg ball is dropped from a height and hits the ground at a velocity of -9 m/s (the negative sign shows the downward direction of the ball's motion). After
touching the ground for a short period of time, the ball bounces back at a velocity of +8.5 m/s. What is the impulse on the ball due to the floor?
Answer:
Impulse = Δp = 2.45 kg m/s
Explanation:
Impulse = change in momentum = final momentum - initial momentum
The initial momentum of the ball before hitting the ground is given by:
m * v_i = 0.14 kg * -9 m/s = -1.26 kg m/s
The final momentum of the ball after bouncing back is given by:
m * v_f = 0.14 kg * 8.5 m/s = 1.19 kg m/s
So the change in momentum is:
Δp = v_f - v_i = 1.19 kg m/s - (-1.26 kg m/s) = 2.45 kg m/s
Impulse = Δp = 2.45 kg m/s

a student conducts an experiment in which a cart is pulled by a variable applied force during a 2 s time interval. in trial 1, the student exerts the force on a cart of mass m . in trial 2, the student exerts the force on a cart of mass 3m .
As long as the force and time are the same, all vehicles experience the same change in momentum, regardless of their mass.
Given the time interval force applied on cart = 2s
The mass of cart in trail 1 = m
The mass of cart in trail 2 = 3m
The mass of cart in trail 3 = 5m
From Newtons laws of motion: F = ma where F is the force applied and a is the acceleration and v = v0 + at where v0 is the initial velocity.
So, v = v0 + (F/m)t
We know that momentum is defined as mass x velocity such that:
p = mv then the change in momentum is seen as: Δp = mv - mv0
Δp = m(v0 + Ft/m) - mv0
Δp = Ft

A runner completes one lap around a circular track with at a time of 252 s252 s at a constant speed of 3.5 m/s3.5 m/s. A - What is the radius, in meters, of the track? B - What was the nunner's centripetal acceleration, in meters per squared second, during the run?
A) The circumference of the track is equal to the distance traveled by the runner in one lap, or C=vt, where v is the velocity and t is the time. So the radius of the track is approximately 70.11 m.
B) The centripetal acceleration is the acceleration towards the center of the circle. So the runner's centripetal acceleration during the run was approximately 0.25 m/s^2.
Centripetal acceleration is a type of acceleration that acts in a direction that is towards the center of a circular path. It is defined as the rate of change of the velocity vector of an object moving in a circular path. The magnitude of centripetal acceleration is given by the equation a = v^2/r, where v is the velocity of the object and r is the radius of the circular path.
Centripetal acceleration is responsible for keeping an object moving in a circular path. Without centripetal acceleration, the object would fly off in a straight line clue to its tangential velocity. For example, when a cor takes o tum, the friction between the tires and the road generates a centripetal force that pulls the car towards the center of the turn, creating centripetal acceleration.

The diameter of the stream below the opening of the faucet is 1.94 cm.
How to find diameter?The diameter of the stream can be found using the formula for the velocity of steady flow in a cylindrical stream:
v = Q / (πr²)
Where Q is the volume flow rate (volume per time), v is the velocity, and r is the radius of the stream.
By rearranging this equation and using the known values of the volume and time, find the radius of the stream 13.0 cm below the opening of the faucet:
r² = Q / (πv) = (125 cm³) / (π x (13.0 cm)² / 4)

part a of the drawing shows a bucket of water suspended from the pulley of a well; teh tension in the rope is 92.0 n. part b shows the same bucket of water being pulled up from the well at a constant velocity. what is the tension in the rope in part b?
In part b of the drawing, the bucket of water is being pulled up from the well at a constant velocity. In this situation, the tension in the rope must provide the force necessary to balance the weight of the bucket and any friction forces.
The force required to lift the bucket is equal to the weight of the bucket plus the force of friction. If the tension in the rope is less than the force required to lift the bucket, the bucket will not move. If the tension in the rope is greater than the force required to lift the bucket, the bucket will accelerate upward.
Since the bucket is being lifted at a constant velocity, this means that the tension in the rope must equal the force required to lift the bucket. Therefore, the tension in the rope in part b of the drawing is equal to the weight of the bucket plus the force of friction. If this value is not given, it cannot be determined without additional information.

The period is related to the angular frequency (w) by the formula: T = 2 x pi / w. In this case, the angular frequency is 10 rad/s, so the period is T = 2 x pi / 10 = 0.6283s. The frequency is then: f = 1 / T = 1 / 0.6283 = 1.5915 Hz.
b) The maximum speed of the block is given by the formula: v max = A w, where A is the amplitude of the oscillation and w is the angular frequency. In this case, the amplitude is 10 cm, so the maximum speed is: v max = 10 x 10 = 100 cm/s.
c) The maximum speed occurs at the points of maximum displacement, which are at x = +/- A, where A is the amplitude. In this case, x = +/- 10 cm, so the maximum speed occurs at x = +/- 10 cm.
d) The maximum acceleration is given by the formula: a max = w x A. In this case, a max = 1000 cm/s².
e) The maximum acceleration occurs at the points of maximum velocity, which are at A where A is the amplitude. In this case, x = +/- 10 / sqrt(2) = +/- 7.07 cm, so the maximum acceleration occurs at x = +/- 7.07 cm.
f) The force required to produce the given oscillation is given by Hooke's law: F = - k x x, where k is the spring constant and x is the displacement of the block from its equilibrium position. Since the displacement of the block is given by x = (10 cm) cos[(10 rad/s)t + pi/2], we cannot determine the force without knowing the value of the spring constant, k.

a light bulb is attached to a battery and lights up. which of the following statements is true about the electric field inside the bulb filament
Due to the potential difference and the current flowing through the filament, an electric field will be created. Because of the electric field that the flowing current created, the field must not be zero. So, option C is correct.
A current travels across the filament when the light bulb is connected to a battery and turned on. The voltage differential between the filament's two ends and the resistance of the filament's material combine to produce the electric field inside the filament. The filament glows because of resistance that the current encounters as it passes through it. Near the center of the filament, where the temperature is highest and the material has the maximum resistance, the highest resistance and hence the largest electric field can be found. As the filament reaches its ends, where resistance is lowest, the electric field inside it becomes weaker and less constant.
