Answer:— A square labeled Object B is shown with an arrow pointing up labeled 3 N, an arrow pointing right labeled 2 N, an arrow pointing down labeled 3 N and an arrow pointing left labeled 1 N. In which direction will the objects move? Object A will move down and Object B will move up.
Explanation:
Answer:
7.15/2 = 3.575m
1.78cos(45.4) = 1.25m
radius = 3.575 + 1.25 = 4.825 m
mg of seat = 10 x 9.8 = 98 N
98/sin(45.4) = 137.64 N
Horizontal force = 137.64cos(45.4) = 96.64 N
Centripetal force = 96.64 N
96.64/10 = 9.6644 = ca
9.6644 x 4.825 = v^2 = 46.63, sq-root = v = 6.83 m/s
(10 + 28.3) x 9.8 = mg = 375.34 N
375.34/sin(45.4) = 527.14 N

Answer:
8.6 m/s
Explanation:
We can find the final velocity of the dog by using the following SUVAT equation:
where
u is the initial velocity
a is the acceleration
d is the distance covered
For the dog in the problem, we have
u = 1.5 m/s
And the distance covered is
d = 3.0 m
Therefore, we can re-arrange the equation to find the final velocity, v:
Answer:
Pressure = Density x Gravity acceleration x Height
Density of water = 1000 Kgm^-3
Gravity acceleration = 9.8 ms^-2
So it is 4.50.
