Answer:
B - False
Explanation: a dispersed formation means spreading out, more like an attacking or advancing position. This doesn't depict a defensive measure.
To solve this problem we will use the relationship given between the centripetal Force and the Force caused by the weight, with respect to the horizontal and vertical components of the total tension given.
The tension in the vertical plane will be equivalent to the centripetal force therefore

Here,
m = mass
v = Velocity
r = Radius
The tension in the horizontal plane will be subject to the action of the weight, therefore

Matching both expressions with respect to the tension we will have to


Then we have that,


Rearranging to find the velocity we have that

The value of the angle is 14.5°, the acceleration (g) is 9.8m/s^2 and the radius is



Replacing we have that


Therefore the speed of each seat is 4.492m/s
Answer:
D.
Explanation:
reasons why not all collisions between reactant molecules lead to reaction
1.The total energy of two colliding molecules is less than some minimum amount of energy.
2. Molecules cannot react with each other unless a catalyst is present.
hence the correct option will be D that is 1 and 2.
Answer:
Bb
Explanation:
If the fish is brown, it had the dominant genotype.
Wavelength = (speed) divided by (frequency) = 10/0.5 = <span>20 </span>
