I can possibly use carpet or floor mats on the floor, especially in front of the door to cover the crack that may be underneath it.
Answer:
v = 10 m/s
Explanation:
Given,
Length of the vine, l = 36 m
Angle of inclination = 31.0◦ with the vertical
acceleration due to gravity = 9.81 m/s²
Using Conservation of energy
KE = PE
v = 10 m/s
Hence, the speed of the swing is equal to 10 m/s
Answer:
8 m/s²
Explanation:
α = 0.04 rad/s²
w = 0.2 rad/s
t = ?
α = w/t
===> t = w/α = 0.2/0.04 = 5 sec
v = wr = 0.2 × 200 = 40 m/s
the net acceleration a = v/t = 40/5 = 8 m/s²
Answer:
The answer is the first option, vacuole.
Explanation:
The name vacuole has its origins in the Latin word vacuus meaning 'empty' and this unfortunately is how vacuoles appear in many slide preparations and photographs. The fact that vacuoles are fluid filled and that different vacuoles within the same cell can contain different chemicals is not normally visible.
