Why is calcium chloride an ionic bond

Physics
2 answers:
ki77a [65]2 years ago
6 0

Answer:Ionic compounds generally form between elements that are metals and elements that are nonmetals. For example, the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl2). In this compound, there are two negative chloride ions for each positive calcium ion.

Suppose a 65 kg person stands at the edge of a 6.5 m diameter merry-go-round turntable that is mounted on frictionless bearings
ozzi

Answer:

0.3165\ \text{rad/s}

Explanation:

m = Mass of person = 65 kg

d = Diameter of round table = 6.5 m

r = Radius = \dfrac{d}{2}=3.25\ \text{m}

v = Velocity of person running = 3.8 m/s

I_t = Moment of inertia of turntable = 1850\ \text{kg m}^2

Moment of inertia of the system is

I=I_t+mr^2\\\Rightarrow I=1850+65\times 3.25^2\\\Rightarrow I=2536.5625\ \text{kg m}^2

As the angular momentum of the system is conserved we have

L_i=L_f\\\Rightarrow mvr=I\omega_f\\\Rightarrow \omega_f=\dfrac{mvr}{I}\\\Rightarrow \omega_f=\dfrac{65\times 3.8\times 3.25}{2536.5625}\\\Rightarrow \omega_f=0.3165\ \text{rad/s}

The angular velocity of the turntable is 0.3165\ \text{rad/s}.

An object moves with constant acceleration 3.45 m/s2 and over a time interval reaches a final velocity of 14.0 m/s.
Sav [38]
Assuming the object was originally at rest, it must have been traveling for
14.0/3.45 = 4.06 seconds

1. Describe the components of the reflex arc
labwork [276]
The simplest arrangement of a reflex arc consists of the receptor, an interneuron (or adjustor), and an effector; together, these units form a functional group. Sensory cells carry input from the receptor (afferent impulses) to a central interneuron, which makes contact with a motor neuron.
