Speed = Distance/time
Speed = 800/40
Speed = 20 metre per second
Answer:
tan 75/350
Explanation:
the cliff is the height 75 and the length is 350 the other side is added to form a triangle . the tan rule is then used.
Answer:
correct option is b. 31.3 m/s
Explanation:
given data
artificial gravity a1 = 1 g
artificial gravity a2 = 2 g
diameter = 100 m
radius r= 50 m
speed v1 = 22.1 m/s
solution
As acceleration is ∝ v²
so we can say
.....................1
put here value
solve it
v2 = × 22.1
v2 = 31.25 m/s
so correct option is b. 31.3 m/s
Nuclear fusion is the name of the reaction where two hydrogen nuclei combine to form a helium nucleus. That's approximately the third choice in that big amorphous blob of choices.
We have no way to tell what nuclear process is illustrated by the equation that Carla is looking at, because we don't know what that equation looks like.
Answer:
angle of twist of the bar is 3.32 × degree
Explanation:
given data
torque t = 571 lb-ft = 774.172 Nm
g = 18,431, 356 lb/ in² = 1.27 × Pa
d1 = 8.1 in = 0.205 m
d2 = 1.8 in = 0.045 m
L = 3.1 ft = 0.944 m
to find out
angle of twist of the bar
solution
first we get here polar moment that is express as
polar moment = ...........1
here do is outer diameter that is 0.205 m and d1 is inner diameter i.e 0.045 m
put here value we get
polar moment =
polar moment = 173.006 ×
now we get here angle that is
angle = ..............2
here T is torque and L is length and J is polar moment and G is share modulus
put these value in equation 2 we get
angle =
angle = 3.32 × degree
