Answer:
Mass of P4O6=103.4
P4O10=133.48
Explanation:
Balanced reaction is:
8P +8 ⇒
+
Both reactant completely vanishes as equivalent of bot are equal.
Moles of P= =3.80
Moles of =
=3.80
No. of moles of formed product are equal and is th of mole of any of reactant.
Thus weight of =
×220 ≈103.41
weight of =
×284 ≈133.48
Jasmine pushes an object a distance of 15 m at constant speed. It produces a 450J of work on the object. What strength Jasmine does it exert on the object?
Answer:
30J
Explanation:
Given parameters:
Distance moved = 15m
Work done = 450J
Unknown:
Strength Jasmine applied = ?
Solution:
The strength Jasmine applied or exerted on the object is the force of pull that cause the motion of the object and the distance it was moved.
Now;
Work done = Force x distance
So;
450 = Force x 15
Force = = 30J
