If the substance doesn't change chemically, it is a physical reaction.
The approximate height of the tsunami in Alaska in 1958 is 1720ft
Answer:
the bending moment will be W from either sides
Explanation:
bending moment= force (load) * perpendicular distance, if I understand the question the distance will be 1/2 of the length
=> f x 1/2(l) =W*1/2(2) =W
Heat is the answer but I need to use 20 characters to post :)
Answer:
t = 8.33 minutes
Explanation:
given,
Speed of Light, v = 3 x 10⁸ m/s
distance between sun to Earth = 1.5 x 10¹¹ m
time taken to reach earth = ?
we know,
Distance = speed x time


t = 500 s
1 min = 60 s
now, 
t = 8.33 minutes
time taken by the light to reach earth is equal to 8.33 minutes.
