Answer:
Here,
density (d) = 1000 kg/m^3
gravity (g) = 10 m/ s^2
height (h) = 2m
Now,
liquid pressure = hdg
=2 x 1000 x 10
=20000 N/m^2
Thus, the liquid pressure is 20000 N/m^2

what is the relationship between the variables on this graph? The temperature does not have an effect on flow time. As the temperature increases, the flow time increases. As the temperature increases, the flow time decreases.
Answer: As the temperature increases, the flow time increases.
Explanation: i took the test
The relationship between the variables on this graph is that As the temperature increases, the flow time increases, therefore the correct answer is option B.
What is the kelvin scale of temperature?It is a scale of temperature used to measure the temperature, the kelvin scale of temperature is also known as the absolute scale of temperature.
The Standard International unit of thermodynamic temperature is the kelvin, often known less frequently as the degree Kelvin. The formal definition of one kelvin is 1/273.16 of the thermodynamic temperature of pure water's triple point.
As shown in the graph as the temperature increase across the X axis the flow time is increasing as well, these two variables are directly proportional to each other.
Thus, The graph shows a link between the variables, showing that when the temperature rises, flow time also rises, hence option B is the proper response.

Explanation:
What is the speed of a walking person in m/s if the person travels 2000 m in 35 minutes?
Distance = 2000m
Time = 35 minutes = 35×60 sec = 2100 sec
We know, Speed = Distance/Time
Therefore, Speed
= 2000m/2100s = 20/21 m/s
Answer: 20/21 m/s

An apple weighing 1 N falls through a distance of 1m. How much work is done
on the apple by the force of gravity?
Answer:
W = F × d
W = 1 × 1
W = 1 Joule
step by step explanation
An apple is having a force of 1 N and it travels to a distance of 1 m then the work done on the apple by the force of gravity will be equal to 1 J.
What is Work?Work is a physics term used to describe the transfer of energy that occurs when an object changes above a distance because of an external force, at least some of which is given in the vector of the dislocation. The element of the strong acting all along the path multiplied by the length of the path can be used to calculate work if the force is constant.
Mathematically, this idea is expressed as W = fd, where W is the effort and f is the force multiplied by d, the distance. Work is completed whenever the pressure is applied at an angle with regard to displacement.
As per the given information in the question,
Force, f = 1 N
Distance, d = 1 m
Then, the work done will be,
W = fd
W = 1 × 1
W = 1 J.

Fatima is watching her pet cat, Winter, napping in the sun. Fatima is curious about the heart rate of Winter when she is napping, so she develops this scientific question: Does a cat’s heart rate change while it is napping
We have that for the question, Does a cat’s heart rate change while it is napping?
Cats heart rate do not increase while napping.
The range of heart beat of a cat is 140 and 220 bpm
From the Question we are asked
Does a cat’s heart rate change while it is napping.
The answer is NO
Cats heart rate do not increase while napping. Cat have a normal heart beat maximum of 220 beats per minute consistently.The range of heart beat of a cat is 140 and 220 bpm
Therefore
There is something with a cat with heart rate above this number.

1. The atomic number of an element is the same as the number of ______ that the element has.
Answer:
Explanation:
The total number of protons in the nucleus of an atom gives us the atomic number of that atom. It is represented with the letter ‘Z.’ All the atoms of a particular element have the same number of protons, and hence the same atomic number. Atoms of different elements have different atomic numbers.
Precision is how close a series of measurements are to ______
Answer:
Accuracy is how close a measured value is to an accepted value. Precision is how close measurements are to one another. To make measurements, you have to evaluate both the accuracy and the precision to get a correct value.
A projectile is launched vertically with an initial velocity of 50 m/s. How long would it take to reach the top of the launch?
Answer:
Explanation:
Givens
vi = 50 m/s
vf = 0
a = - 9.81
t = ?
Formula
t = (vf - vi)/a
Solution
t = (0 - 50)/-9.81
t = 5.097
Notice that a is made into a minus. It does not mean subtract. It means that the direction of the projectile and gravity must go in opposite directions. You will find that direction is a critically important consideration in physics.
Answer:
It'd take it 5.10 seconds
Explanation:
At the top of the launch, it is maximum height, h
formular derivation :
At maximum height, final velocity, v is zero
From first newtons equation:
[tex]{ \sf{v = u + gt}}[/tex]
v is the final velocity
u is the initial velocity
g is acceleration due to gravity
t is the time taken
but v is zero:
[tex]0 = u + gt \\ gt = u \\ t = \frac{u}{g} [/tex]
since it is vertical motion, u = usin(theta), where angle is 90°
[tex]{ \boxed{t = \frac{u \sin( \theta) }{g} }}[/tex]
t is the time taken to reach the top of the launch:
substitute, taking g to be 9.8 m/s²
[tex]t = \frac{50 \times \sin(90 \degree) }{9.8} = \frac{50}{9.8} \\ \\ { \boxed{ \boxed{time = 5.10 \: seconds}}}[/tex]
