Answer:
hello your question has some missing values attached below is the complete question with the missing values
answer :
a) 0.083 secs
b) 0.33 secs
c) 3e^-4/3
Explanation:
Given that
g = 32 ft/s^2 , spring constant ( k ) = 2 Ib/ft
initial displacement = 1 ft above equilibrium
mass = weight / g = 4/32 = 1/8
damping force = instanteous velocity hence β = 1
a<u>)Calculate the time at which the mass passes through the equilibrium position.</u>
time mass passes through equilibrium = 1/12 seconds = 0.083
<u>b) Calculate the time at which the mass attains its extreme displacement </u>
time when mass attains extreme displacement = 1/3 seconds = 0.33 secs
<u>c) What is the position of the mass at this instant</u>
position = 3e^-4/3
attached below is the detailed solution to the given problem
Answer:
Mass = 10102.04 kilograms.
Explanation:
Given the following data;
Acceleration = 9.8m/s²
Force = 99000N
To find the mass;
Mass = force/acceleration
Mass = 99000/9.8
Mass = 10102.04 kilograms.
Therefore, the mass of the boulder is 10102.04 kilograms.
X - rays are considered an
oxidizing mutagenic agent. The answer is letter A. X-rays are high energy
electrons that can cause damage when exposed under extreme conditions. The best
technology that can block it is t using a lightweight type of metal foam. It
can take in high energy collisions which also exhibits high forces. it does not
only block x-rays but also, neutron radiation and gamma rays.
