A net force of 153 N accelerates a 22.0 kg mass. What is the resulting acceleration?
The resulting acceleration is 6.95 m/s².
Net force (F) = 153 N
Mass (m) = 22.0 kg
To find the resulting acceleration (a), we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. The equation can be written as:
F = m * a
Rearranging the equation, we have:
a = F / m
Substituting the given values, we get:
a = 153 N / 22.0 kg
Evaluating the expression, we find:
a ≈ 6.95 m/s²
Therefore, the resulting acceleration is approximately 6.95 m/s².

Which of the following statement is correct
The density of an object does not remains same if we take small quantity of that substance.
The density of an object remains same irrespective of its shape, size and quantity.
The density of an object does not remains same irrespective of its shape and size.
The density of an object remains same only if its shape and size remains same.
The density of an object remains same irrespective of its shape, size and quantity.
Explanation:
Density is an intensive property. This means that regardless of the object's shape, size, or quantity, the density of that substance will always be the same. Even if you cut the object into a million pieces, they would still each have the same density. It is because density in an intensive property of matter.

Below you will see diagrams showing a trip taken by Fred and a trip taken by Frank. For each person, find their distance, displacement, average speed, and average velocity from A to B. Each square is 10 meters wide, and use words like north, south, east, and west for direction.
The first thing Fred did was go south for 4 seconds. If he wanted to cut his average speed in half, how long should that southward motion last (assuming the other two motions happen in the same time as shown)? Explain your reasoning.
Would this amount of wait-time also have halved his average velocity?
Part A
The completed table of values of the motion of Fred and Frank are;
[tex]\begin{array}{|l|c|c|}&\mathbf{Fred's \ Trip}&\mathbf{Frank's \ Trip}\\\mathbf{Distance}&150 \, m&120 \, m\\\mathbf{Displacement}&30 \, m&50 \, m\\\mathbf{Average \ Speed}&15 \, m/s&10 \, m/s\\\mathbf{Average \ Velocity}&3 \ m/s&4.1 \overline 6 \, m/s\end{array}\right][/tex]
Part B
The time the southward motion should last is 14 seconds
The reason the above values are correct is as follows;
The total distance is given by summing the length of the sides of the square that lay along the path
Known parameters:
For Fred's Trip, we have;
Distance = 60 meters South + 30 meters East + 60 meters north = 150 meters The total distance = 150 meters
Required:
The displacement = 30 meters East
Average speed = Total distance/(Total time)
Total time = 4 sec + 3 sec + 3 sec = 10 sec
Average speed = 150 m/10 sec = 15 m/s
Average velocity = Displacement/Total time
Average velocity = 30 m/10 sec = 3 m/s
Known parameters:
For Frank's Trip, we have;
Distance = 30 meters North + 60 meters East + 30 meters south = 120 meters
The total distance of Frank's trip = 120 meters
Required:
The displacement = 50 meters East
Average speed = Total distance/(Total time)
Total time = 5 sec + 5 sec + 2 sec = 12 sec
Average speed = 120 m/12 sec = 10 m/s
Average velocity = Displacement/Total time
Average velocity = 50 m/12 sec = 4.1[tex]\overline 6[/tex] m/s
Therefore, we have;
[tex]\begin{array}{|l|c|c|}&\mathbf{Fred's \ Trip}&\mathbf{Frank's \ Trip}\\\mathbf{Distance}&150 \, m&120 \, m\\\mathbf{Displacement}&30 \, m&50 \, m\\\mathbf{Average \ Speed}&15 \, m/s&10 \, m/s\\\mathbf{Average \ Velocity}&3 \ m/s&4.1 \overline 6 \, m/s\end{array}\right][/tex]
To reduce his speed in half, we have;
New average speed, s₂ = s₁/2
∴ s₂ = (15 m/s)/2 = 7.5 m/s
Let x represent the time for the southward motion, we have;
(150)/(6 + x) = 7.5
(6 + x) × 7.5 = 150
x = (150 - 7.5×6)/7.5 = 14
Therefore, the time for the southward motion should last for 14 seconds

The number of significant figures in 00.6022009 is 7 .
The number of significant figures is 7.
Explanation:
Significant figures
The figures in a number that expresses the magnitude of a quantity to a specific degree of accuracy are known as significant digits.Digits from 1 to 9 are always significant and have an infinite number of significant figures.All non-zero numbers are always significant. For example, 684, 9.54, and 63.4 all have three significant figures.All zero’s between integers are always significant. For example, 2005, 8.005, and 10.05 all have four significant figures.All zero’s preceding the first integers are not significant. For example, 0.0038 has two significant figures.All zero’s after the decimal point are always significant. For example, 4.500, 43.00, and 950.0 all have four significant figures.All zeroes used solely for spacing the decimal point are not significant. For example, 6000 has one significant figure.Given :
The number 00.6022009
To find:

Answer:

The depth of water near lowermost tube is the greatest so the water comes out of lowermost tube with the greatest pressure and goes farthest from the vessel.
Some students collect some drops of water from a leaking tap.
The students measure the volume of the water they collect.
State the term for the equipment that is suitable for measuring the volume accurately.
Explanation:
The concept of temperature has evolved from the common concepts of hot and cold. Human perception of what feels hot or cold is a relative one. For example, if you place one hand in hot water and the other in cold water, and then place both hands in tepid water, the tepid water will feel cool to the hand that was in hot water, and warm to the one that was in cold water. The scientific definition of temperature is less ambiguous than your senses of hot and cold. Temperature is operationally defined to be what we measure with a thermometer. (Many physical quantities are defined solely in terms of how they are measured. We shall see later how temperature is related to the kinetic energies of atoms and molecules, a more physical explanation.) Two accurate thermometers, one placed in hot water and the other in cold water, will show the hot water to have a higher temperature. If they are then placed in the tepid water, both will give identical readings (within measurement uncertainties). In this section, we discuss temperature, its measurement by thermometers, and its relationship to thermal equilibrium. Again, temperature is the quantity measured by a thermometer.
