Sample Response: Surface tension is the result of
water molecules pulling inward with a strong attractive
force. This attractive force brings the molecules on the
surface of the water close together and causes the surface
of the water to be drawn toward the water molecules
beneath the surface. Since there are no water molecules
above the surface, there are uneven forces. This causes
surface tension, allowing the coin to float on the water's
surface

All the statement are correct about surface tension of water. Due to this force, water surface exhibit peculiar properties compared to the bulk of the system.
What is surface tension ?Surface tension is the potential for liquid surfaces that are at rest to condense into the smallest surface area. Razor blades and insects, which have a density greater than that of water, may float on the surface of the water without even getting partially buried because to surface tension.
Surface tension at liquid-air contacts originates from the liquid molecules' stronger attraction to one another owing to cohesion than to the air molecules due to adhesion.

In the early 1600s, Galileo Galilei performed a series of experiments to measure the acceleration of a ball rolling down a smooth inclined plane. He tried several ways to measure time, including water clocks and his own pulse. Suppose his pulse rate was 66 beats per minute, and he counted 11 beats for the ball to roll down the plane. How many seconds was the ball rolling?

15 percent input work is lost due to friction,then what is the efficiency of machine?
Answer:
{ (x/y )*100 } - 0.15 y
Explanation:
The efficiency of a machine is the percent of output work divided by input work minus work lost from friction and heat.
Assume work output = x
Assume work input percent as =y
Work lost through friction is given as : 15% input work = 0.15 y
Then efficiency of the machine will be :{ (x/y )*100 }- 0.15 y
Use real values for x and y to find the correct efficiency of the machine.

The depth of the deepest footprint is 3 centimeters C. The footprints were made by a dog D. The footprints are oriented in an east-west direction
Answer:
C
C. The footprints were made by a dog.
The student may have noticed specific characteristics or features in the footprints that lead them to believe that they were made by a dog.
Hence, the correct option is C.
An inference is a conclusion or deduction based on evidence or observations. It involves making an educated guess or interpretation about something that may not be explicitly stated.
Out of the provided options, the most likely inference is The footprints were made by a dog.

RACTICE Uranium (molar mass = 283.03 g/mol) has the largest molar mass of any element naturally found on Earth. What is the mass of 7.50 mol of uranium?
Answer:
The answer is 2122.73 gExplanation:
The mass of a substance given it's molar mass and number of moles can be found by using the formula
mass = Molar mass × number of moles
From the question
molar mass = 283.03 g/mol
number of moles = 7.5 mol
So we have
mass = 283.03 × 7.5 = 2122.725
We have the final answer as
2122.73 gHope this helps you

If the velocity of a bicycle is 10 m/s, how long will it take to cover a distance
of 18 km?
(Ans: 1800 s)
1800 sec = 30 min
Explanation:Hi there !
18km = 18×1000m = 18000 m
1 s ............... 10m
x s ...............18000m
x = 1×18000/10 = 1800 sec = 30 min

During a race, a sprinter increases from 4.0 m/s to 6.0 m/s over a period of 1.5 s. What is the sprinter’s average acceleration during this period? (10 Points) 1 meter per second squared 1.3 meters per second 2.0 meters per second 1.3 meters per second squared
Answer:
[tex]a=1.3\ m/s^2[/tex]
Explanation:
It is given that,
Initial velocity, u = 4 m/s
Final velocity, v = 6 m/s
Time, t = 1.5 s
We need to find the average acceleration of a sprinter during this period. We know that the rate of change of velocity of an object is equal to its acceleration. So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{(6-4)\ m/s}{1.5\ s}\\\\a=1.33\ m/s^2[/tex]
So, the acceleration of the sprinter is [tex]1.33\ m/s^2[/tex]. Hence, the correct option is (d).

Explanation:
The phase of cell cycle consists of the cell readying itself for its division is called prophase of the cycle. It is the first phase in mitosis at which a cell duplicate into two daughter cells.
What is cell cycle?Cell cycle is a biological process by which a cell divide into two genetically identical daughters cells. Prophase is the initial stage of cell division in both mitosis and meiosis. When the cell reaches prophase, DNA replication has already started after interphase.
The chromatin reticulum condenses and the nucleolus vanishes during prophase, which are the key events. Other phases are interphase, anaphase etc. and the last stage is called the telophase.
Cell cycle is a very important biological process by which organisms are producing their offspring. This process differ in each level of organism where for all the starting phase is called prophase.

a stone thrown horizontally from the top of a vertical wall with a velocity of 15m/s,hits the horizontal ground at a point 45m from the base of the wall. calculate the height of the wall. g =10m/s
Answer:
The height of the wall is 45 m
Explanation:
Horizontal Motion
When an object is thrown horizontally with an initial speed v from a height h, the maximum horizontal distance traveled by the object, also called the range can be calculated as follows:
[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]
If we know the range and want to calculate the height it was thrown from, we solve the equation for h:
[tex]\displaystyle h=\frac{d^2g}{2v^2}[/tex]
We'll use the approximate value of g=10\ m/s^2.
The stone was thrown from the top of a wall with a speed of v=15 m/s and it hits the ground d=45 m away from the base of the wall. Calculating:
[tex]\displaystyle h=\frac{45^2\cdot 10}{2\cdot 15^2}[/tex]
[tex]\displaystyle h=\frac{2025\cdot 10}{2\cdot 225}[/tex]
[tex]\displaystyle h=\frac{20250}{450}[/tex]
h = 45 m
The height of the wall is 45 m
