Answer:
Unknown
Explanation:
Because we cannot observe space beyond the edge of the observable universe, it is unknown whether the size of the Universe in its totality is finite or infinite.
Newton’s second law is that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
Answer:
a) 14.2sec
b) 1394m away if horizontal speed never changes
c) 9.8m/s
Explanation:
Answer:3.98cm
Explanation:
given data
mass of object
=0.5kg
intial extension=5 cm
elevator acceleration=2 m/
From FBD of intial position
Kx=mg
K=
k=98.1 N/m
From FBD of second situation
mg-k
=ma
k=m(g-a)
=
=3.98cm
