Answer:
A. There are 6.02 x 1023 items in a mole, which equals Avogadro's
number
Explanation:
The mole of a substance is
Explanation:
energy cannot be created or destroyed, but only changed from one form to another or transferred from one object to another.
Answer:
0.000047N
Explanation:
We know that
intensity (I) = P/ A
Where
P= power
A= Area
So lets say that the power absorbed
Will be = Intensity x Area
Which Is = 1.4 x 10^3 x(10)
So
14000 Watt = 14 kWatt
However we know that radiation pressure is equal to
time-averaged intensity all over the speed of light in free space
So
P = (1.4 x 1000)/c
But
F= P x A
So
((1.4 x 1000)/(3 x1 0^8)) x 10
Which is
=0.000046666N
To two SIG figures we have
=0.000047 N
Answer:
t = 4 sec
Explanation:
given,
height of the cliff = 256 ft
equation of height and time
h(t) = 256 - 16 t²
time at which the ball hit the ground = ?
when the ball hit the ground height of the cliff is equal to zero
h(t) = 0
now,
0 = 256 - 16 t²
16 t² = 256
t² = 16
t = 4 sec
hence, height of the ball will be equal to zero when time is 4 seconds.
