List at least three factors that would cause an organism to migrate one habitat to another
GalinKa [24]

1. Escaping a predator – this increases its chances of survival. It could move to an area with low predator population

2. Finding food – food might get scarce in the current habitat and hence increased competition in the community. Finding another habitat with a higher availability food will increase survival

3. To find a mate/ to reproduce – reproduction in an intrinsic compulsion in all animals as a means to perpetuate their own gene. Solitary animals, such as the leopard, leave their habitat to find a mate and reproduce.

The water side of the wall of a 60-m-long dam is a quarter-circle with a radius of 7 m. Determine the hydrostatic force on the d
tamaranim1 [39]

Answer:

26852726.19\ \text{N}

57.52^{\circ}

Explanation:

r = Radius of circle = 7 m

w = Width of dam = 60 m

h = Height of the dam will be half the radius = \dfrac{r}{2}

A = Area = rw

V = Volume = w\dfrac{\pi r^2}{4}

Horizontal force is given by

F_x=\rho ghA\\\Rightarrow F_x=1000\times 9.81\times \dfrac{7}{2}\times  7\times 60\\\Rightarrow F_x=14420700\ \text{N}

Vertical force is given by

F_y=\rho gV\\\Rightarrow F_y=1000\times 9.81\times 60\times \dfrac{\pi 7^2}{4}\\\Rightarrow F_y=22651982.59\ \text{N}

Resultant force is

F=\sqrt{F_x^2+F_y^2}\\\Rightarrow F=\sqrt{14420700^2+22651982.59^2}\\\Rightarrow F=26852726.19\ \text{N}

The hydrostatic force on the dam is 26852726.19\ \text{N}.

The direction is given by

\theta=\tan^{-1}\dfrac{F_y}{F_x}\\\Rightarrow \theta=\tan^{-1}\dfrac{22651982.59}{14420700}\\\Rightarrow \theta=57.52^{\circ}

The line of action is 57.52^{\circ}.

You are conducting an experiment inside a train car that may move along level rail tracks. A load is hung from the ceiling on a
katrin2010 [14]

Answer:

b

c

e

h

Explanation:

Note that the swing direction was not giving in the question and direction could be sideways (in a turn) or in a track or both

The question show something in common ...acceleration

So let's look at the statements and pick the correct ones

a is false while b is correct as the train is accelerating

c is correct. The train is accelerating even thou the speed could not be ascertained

d is false and not feasible as the train is accelerating

e is true as the train maybe moving at a constant speed in a circle

f is false. This could be constant velocity in a circle. Same as g (false)

h is true. It's accelerating
