Hope this helps:) Have a good day!!
Answer:
The correct option is;
Absolute zero
Explanation:
A Bose-Einstein condensate is known as the fifth state of matter which is made of a collection of ultra cooled atoms (at almost absolute zero degrees -273.15 °C) such that the there is very slight free energy within the atoms which results in almost no relative motion between the atoms. The atoms then combine forming clumps such that phenomena usually observed at the microscopic level such as wavefunction interference become observable at the microscopic level.
Answer:
11320.63 Pa
Explanation:
= Pressure the heart is pumping at = (assumed)
= Density of blood = 1060 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
h = Height = 0.45 m
From Bernoulli's equation we have
The pressure in the artery is 11320.63 Pa
Answer;
= 13.33 m/s²
Solution;
From the second Newton's law of motion;
F= ma
F is the force = 40 N
M is the mass = 3 kg
a is the acceleration;
40 = 3 × a
a = 40/3
= 13.33 m/s²
Hence; the maximum acceleration the bag can withstand before ripping is 13.33 m/s²
The range is
We know that in cinematic problems the velocity in different directions is independent, so on the y-axis, or the y-velocity we have the gravity acceleration changing the velocity, although on the x-axis, or the x-velocity we don't have any acceleration, so the velocity is constant, so, we can use the basic cinematic equations and adapt them for our problem:
We can simplify it, we know that all the initial position on the x-axis is zero, but the initial position on the y-axis is 30, we also know that the initial velocity on y-axis is zero, so
I won't put numbers know, let's do all the manipulation first.
When the ball hit the ground we know that his position is 0 on the y-axis, so
Now we know when the ball hits the ground, so we can use this time on the position equation on the x-axis and find out the distance the ball travelled
That's all! we can just put the values know.
