Answer:
In physics, special relativity (also known as the special theory of relativity) is the generally accepted and experimentally confirmed physical theory regarding the relationship between space and time.
We need special relativity in order to solve for quantum gravity. ... The earth was expanding (thus, it's mass was expanding) through space in all directions in order to create gravity **OOPS** forgot, specifically at an accelerating rate… OR… The space must be pushing toward or down on the earth, from every direction.
Answer:
Total weight of the hot tub and water is 5676.6 pounds-force
Explanation:
rho = 62.4lbm/ft^3 × 1ft^3/7.481gal = 8.34lbm/gal
Mass of water = rho × volume = 8.34lbm/gal × 600 gallons = 5004lbm = 5004×0.45359kg = 2269.8kg
Total mass of hot tub and water = 320kg + 2269.8kg = 2589.8kg
Local acceleration due to gravity = 32ft/s^2 = 32ft/s^2 × 1m/3.2808ft = 9.75m/s^2
Total weight of hot tub and water = 2589.8kg × 9.75m/s^2 = 25250.55N = 25250.55/4.4482 lbf = 5676.6 lbf
Answer:
a = 0.16 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 3.2 [m/s]
Vo = initial velocity = 1.1 [m/s]
t = time = 13 [s]
a = acceleration [m/s²]
Now replacing:
![3.2=1.1+a*13\\2.1=13*a\\a=0.16[m/s^{2} ]](https://tex.z-dn.net/?f=3.2%3D1.1%2Ba%2A13%5C%5C2.1%3D13%2Aa%5C%5Ca%3D0.16%5Bm%2Fs%5E%7B2%7D%20%5D)
It would weaken the bones and thy would not be as strong or tough
