First, we calculate the mass of Phosphorous present:
283.88 x 0.4364
= 123.88 amu
Atomic mass of P is 31 amu
moles of P = mass / Ar
= 123.88 / 31
= 4.0 moles
We know that one mole of substance has 6.02 x 10²³ particles
Atoms of P = 4 x 6.02 x 10²³
= 2.41 x 10²⁴ atoms

Explanation:
Answer:
8.37 Joules
Explanation:
The amount of energy that a substance, such as animal tissue or rubber can take and yet return to its original condition is known as resilience. When we stress such a substance and then let it restore to its previous state, we are referring to the substance to maintain its elastic area of the stress-strain curve.
From the given information:
the resilence is 0.93
The amount of work done during stretching of the tendon = 9.00 J
Thus,
the work done when relaxing = 0.93 × 9.00 J
= 8.37 Joules
Answer:
3054.32618 rad/s²
-431.1989 rad/s²
29080
Explanation:
Converting angular speed to rad/s


The average acceleration while speeding up is 3054.32618 rad/s²
The number of turns in the 1.2 seconds

The number of rotations in the 1.2 seconds is 349.99
Number of rotations in the 45 seconds


Average angular acceleration while slowing down -431.1989 rad/s²

Number of rotations while slowing down is 2479.16718
Total number of rotations is 349.99+26250+2479.16718 = 29079.15718 = 29080
