Newtons Law of motion
HOPE IT HELPS:)
Answer:
The lungs are lateral to the heart.
Explanation:
Momentum is conserved, so the total momentum before collision is equal to the total momentum after collision. Take the right direction to be positive. Then
(3.00 kg) (2.09 m/s) + (2.22 kg) (-3.92 m/s) = (3.00 kg) (-1.71 m/s) + (2.22 kg) <em>v</em>
where <em>v</em> is the velocity of the 2.22 kg block after collision. Solve for <em>v</em> :
6.27 kg•m/s - 8.70 kg•m/s = -5.13 kg•m/s + (2.22 kg) <em>v</em>
(2.22 kg) <em>v</em> = 2.70 kg•m/s
<em>v</em> = (2.70 kg•m/s) / (2.22 kg)
<em>v</em> ≈ 1.22 m/s
i.e. a velocity of about 1.22 m/s to the right.
Answer:
Explanation:
Given:
cross sectional area of the bone, 
factor of up-scaling the dimensions, 
Since we need to find the upscaled area having two degrees of the dimension therefore the scaling factor gets squared for the area being it in 2-dimensions.
The scaled up area is:
![a_s=[4.8 \times 10^{-4}]\times 10^2](https://tex.z-dn.net/?f=a_s%3D%5B4.8%20%5Ctimes%2010%5E%7B-4%7D%5D%5Ctimes%2010%5E2)
Answer:
2.4525 N
Explanation:
The earths gravity is 9.81 N/Kg
And so to work this out you would multiply 9.81 by 0.250 which equals to 2.4525N
