Answer:
pre water pressure
Explanation:
given data:
frictional angle 25°
unconfined xompressive strength qu = 133 kN/m2
for clay, unconfined compressive strenth is cu
cu = 133/2 =66.5 kN/m2
cell pressure is zero in uncomfined compressive strenth test
from principle effective stress we have
as this test is quick test i.e. undrained test therefore
pre water pressure
Answer:
a) 4.485 kg b) 3.94 kg
Explanation:
since the maximum tension the line can stand is 44 N and for question a the speed is constant (acceleration must be zero since the velocity or speed is not changing), F(tension) = mass * acceleration due to gravity (g) .
44 = m * 9.81m/s^2
m = 44/9.81 = 4.485kg
b) F(tension) = ma + mg ( where a is the acceleration of the body and g is the acceleration of the gravity)
44 = m (a +g)
44 = m (1.37 + 9.81)
44/11.18 = m
m = 3.94 kg
A. Speed up is the answer. Hope it is right.
Answer:
Speeed
Explanation:
The speed of an object is defined as the rate of change of distance:
where
d is the distance covered by the object
t is the amount of time needed to cover that distance
Speed is measured in meters per second (m/s). It should be noted that speed is a scalar quantity, so it only has a magnitude (and no direction).
I translated it so I could help, but please try putting the question in English.
You are supposed to use charles' law here. V1/T1 = V2/T2. Temps should be converted to kelvin, so K = C + 273. You are finding V2, so solving for V2 makes it V1*T2/T1 = 0.5 * 313/293 = 0.534 liters
