Answer:
T = 540 N (to two significant digits)
Explanation:
Let the crate dimension L be from strap attachment to floor contact
Let T be the strap tension
sum moments about the floor contact point to zero
mg[½Lcos25] - Tsin61[Lcos25] + Tcos61[Lsin25] = 0
L is common to all terms, so divides out.
½(71)(9.8)cos25 = T(sin61cos25 - cos61sin25)
T = (71)(9.8)cos25 / (2(sin61cos25 - cos61sin25))
T = 536.428020...
Answer:
d = 49.5 m
hence we can say it is conceivable that he can distinguish sports stadiums on earth's surface but in Private houses? Cars? it can not becayuse they are are very small
Explanation:
Given data
altitude = 150 km
diameter = 2.0 mm
wavelength = 550 nm
to find out
is it conceivable that he can distinguish sports stadiums
solution
we will apply here formula that is
∅ = 1.2 λ / D
put here λ = 550 × m and D = 2 ×
m
∅ = (1.2 ) 550 × / 2 ×
∅ = 3.30 × rad
so
d = 150 × × 3.30 ×
d = 49.5 m
hence we can say it is conceivable that he can distinguish sports stadiums on earth's surface but in Private houses? Cars? it can not becayuse they are are very small
