According to the following formula, the answer is 2,300 g or 2.3 kg:
Volume (m)/Mass (m) Equals Density (p) (V)
Here, the density is 1.15 g/mL, allowing the formula described above to result in a mass of 2.00 L:
p=m/V
1.15 g/mL is equal to x g/2.00 L or x g/2,000 mL.
2,000 mL of x g = 1.15 g of g/mL

What is the relationship between the magnitude of the angular velocity ω and that of the velocity v ?ω = v / r
Since the cylinder is wrapped about the string, it rolls without slipping with respect to the string. The constraint relationship to assure this kind of motion can be obtained by considering the relative velocity of the point on the cylinder that is in contact with the string with respect to the string it should be zero.
The velocity of the center of the cylinder,
v = dy (t) / dt, r and the rotation rate of the cylinder, ω
We have to first find the velocity of the contact point relative to the center of the cylinder. Since this ignores the translational motion of the entire cylinder with respect to the ground, we then need to add back in the cylinder's center of mass velocity to find the velocity of the contact point with respect to the ground.
So, v (contact) = ωr - v where,
ω is the angular velocity
v is the linear velocity
r is the radius
ω = v / r

If the entire apparatus is immersed in water, what happens to the distance between the fringes on the screen?
The space between the screen fringes will be closed if the complete apparatus is submerged in water.
What does fringe distance mean?The space between two consecutive bright spots (maximas, when constructive interference occurs), or two consecutive dark patches, is known as the fringe width (minimas, where destructive interference occurs). All of the fringes in Young's double-slit experiment are the same length. The formula yields the fringe width. β = λD/d. Because it depends on L, the spacings between various fringes get smaller as the slit distance gets bigger. Since the space between various fringes is wavelength dependent, increasing the light's wavelength also increases that separation.
In comparison to air, water has a shorter wavelength of light. Therefore, when the device is submerged in water, the fringe width will diminish.

If an automobile gets 24.5 miles to the gallon and the cost of gasoline is $2.75 a gallon, how much will it cost to drive 975 km?
It will cost $68 to travel 975 kilometers for an automobile if the cost of gasoline is $2.75 per gallon.
This simple calculation can be explained as below calculation of the cost of driving such a distance is done by conversion of the distance into miles and multiplying such distance by $2.75.
Cost of DrivingFirst calculate the kilometers to miles.
975 kilometers is converted as 605.837 miles. Now the division of mileage of automobile will be calculated as,
Gasoline required = Distance travelled/ mileage
=605.837/24.5
=24.72 gallons of gasoline required.
Now we have to calculate the cost of gasoline.
Gasoline cost= gallons x cost per gallon
= 24.72 x 2.75
=$68
So, it is calculated that the cost of gasoline/ cost of driving is $68.0.

A car with good tires on a dry road can decelerate at about 3.0 m/s2 when braking. if the car is traveling at 65 km/h, what distance is needed to stop at the red light?
By using uniform motion, the distance needed to stop at the red light is 54.36 m.
We need to know about the uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule
vt = vo + a . t
vt² = vo² + 2a . s
s = vo . t + 1/2 . a . t²
where vt is final velocity, vo is initial velocity, a is acceleration, t is time and s is displacement.
From the question above, we know that
a = -3 m/s²
vo = 65 km/h = 18.06 m/s
vt = 0 m/s
By using the second equation, we get
vt² = vo² + 2a . s

First, it depends on the cross-sectional/frontal area of the falling object, that is the amount of air the object must plow through as it falls. Second, it depends on the speed of the falling object.
When an object is dropped through the air, it usually faces air resistance. Air resistance is caused by collisions between the object's leading air and surface molecules. Several variables determine the actual degree of air resistance the object faces.
