Answer: 3.48g
Explanation:
here, we will be using conservation of momentum to solve the problem. i.e the total momentum remains unchanged, unless an external force acts on the system. We'll in thus question, there is no external force acting in the system.
Remember, momentum = mass * velocity, then
mass of blood * velocity of blood = combined mass of subject and pallet * velocity of subject and pallet
Velocity of blood = 56.5cm = 0.565m
mass of blood * 0.565 = 54kg * (0.000063/0.160)
mass of blood * 0.565 = 54 * 0.00039375
mass of blood * 0.565 = 0.001969
mass of blood = 0.00348kg
Thus, the mass of blood that leaves the heart is 3.48g
a)
Amplitude of wave is given as maximum displacement from mean position
So here amplitude is 1.25 cm
b)
Wavelength is the length of the wave that it travels in one time period
From graph we can say the wavelength is given as 3cm
PART C)
Time period of wave is the time after which it repeats its shape
Speed of the wave = 21 cm/s
time period = wavelength / speed
Now frequency is
PART D)
Time period = \frac{1}{f}[/tex]
Answer:
the distance of image from the vertex is 45 cm and the image formed is in the glass.
Explanation:
distance of object, u = - infinity
radius of curvature, R = - 15 cm
refractive index, n = 1.5
Let the distance of image is v.
Use the formula
The image is in the glass.
Hey all you can do is type the question on the internet and click on the one that has the same title as yours and the answers will be there im taking physics and i do that all the answers will be there
