Flexibility is the ability of a joint or series of joints to move through an unrestricted, pain free range of motion. Although flexibility varies widely from person to person, minimum ranges are necessary for maintaining joint and total body health.

Which of the following most accurately represents John Dalton’s model of the atom?

deff fn [24]

John Dalton’s model of the atom was the first model of the atom that was proposed. John Dalton discovered the atom which he said composed matter, which is basically anything and everything. He proposed that all matter is composed of atoms which are small and indivisible particles. His model which may be true, is too general and soon were extended by other scientists.

A sprinter accelerates from rest to 9.00 in 1.38 sec.What is his acceleration in a. m/s2b. m/h2

dalvyx [7]

Answer:

a) The acceleration of the sprinter is 6.521 meters per square second, b) The acceleration of 84512.16 kilometers per square hour.

Explanation:

Note: Statement is incomplete, complete description of the problem is: A sprinter accelerates from rest to $9.00\,\frac{m}{s}$ in 1.38 seconds. What is his acceleration in a. $\frac{m}{s^{2}}$ and b. $\frac{km}{h^{2}}$ ?

a) We assume that sprinter accelerates uniformly, so that acceleration ( $a$ ), measured in meters per square second, can be obtained from this kinematic expression as function of initial and final velocities ( $v_{o}$ , $v$ ), measured in meters per second, and time ( $t$ ), measured in seconds, as well.

$v = v_{o} + a\cdot t$

$a = \frac{v-v_{o}}{t}$

If we know that $v_{o} = 0\,\frac{m}{s}$ , $v = 9\,\frac{m}{s}$ and $t = 1.38\,s$ , the acceleration experimented by the sprinter is:

$a = \frac{9\,\frac{m}{s}-0\,\frac{m}{s} }{1.38\,s}$

$a = 6.521\,\frac{m}{s^{2}}$

The acceleration of the sprinter is 6.521 meters per square second.

b) If we know that a hour is equivalent to 3600 seconds and a kilometer is equivalent to 1000 meters, the result of the previous item is converted by using two consecutive unit conversions:

$a = \left(6.521\,\frac{m}{s^{2}} \right)\cdot \left(\frac{1}{1000}\,\frac{km}{m} \right)\cdot \left(3600^{2}\,\frac{s^{2}}{h^{2}} \right)$

$a = 84512.16\,\frac{km}{h^{2}}$

The acceleration of 84512.16 kilometers per square hour.

When the voltage is at a maximum positive value, the current is at a value that is_________.

alukav5142 [94]

Answer:

When the voltage is at a maximum positive value, the the current is at a value that is maximum and positive

Explanation:

We know that the relation between the Voltage and the current is given using the Ohm's law, which states that the voltage (V) is directly proportional to the current (I)

Mathematically,

V ∝ I

Hence,

When the voltage is at a maximum positive value, the the current is at a value that is maximum and positive
