B:A
Explanation:
because the alphabet goes
A B C D E F G
Answer:
2452.5 N/m^2
Explanation:
given:
density =500kg/m^3
viscosity = 10 Pa-s
diameter of tube= 2 m
and L be length
since gravity is the only force shear force will balance it
so we can write
mg=
A=
m=
therefore
putting values we get
calculating we get 2452.5 N/m^2
Answer:
Acceleration is 9.8 m/s^2
Explanation:
If the boulder falls from the cliff then the gravitational force will apply on it and due to gravitational force, the acceleration will be generated. Moreover, the acceleration generated in this case will be called the acceleration due to gravity. Therefore, the acceleration will remain constant irrespective of time and height because the gravitational force is constant. Thus, acceleration is 9.8 meters per second square.
Calculate the 2 horizontal and verticle vectors of the velocity 78 m/s
the horizontal vector is what we want becoz the verticle vector is goin to be 0 at the max height.
the horizontal vector if 7.8Cos(17) = 7.46 m/s
So, now we have the velocity and we already have the mass, we can calculate KE,
.5(m)(v)^2
= 5779.8 J
I hope my answer is right, if not just comment, i will help u
