Answer:
A. That enough light of any frequency would cause electrons to flow.
Explanation:
A P E X
The change in speed of this object is 3m/s
According to Newton's second law;
F = ma
F = mv/t
Given the following parameters
Force F = 8.0N
mass m = 16kg
time t = 4.0s
Required
speed v
Substitute the given parameters into the formula
v = Ft/m
v = 8 * 6/16
v = 48/16
v = 3m/s
Hence the change in speed of this object is 3m/s

Answer:
0.22 b
Explanation:
Quadrupole moment of the nucleon is,

And also,

And, 
Now,

For Bismuth
and A is 209.

Therefore, the expected value of quadrupole is 0.22 b which is quite related with experimental value which is 0.37 b
Answer:
a.6.5025 J
b.6.5025 J
Explanation:
We are given that
Mass of pellet,m=0.27 g=
1 kg=1000 g
Spring constant,k=1800 N/m
x=8.5 cm=
1m=100 cm
a.Potential energy stored in the compressed spring is given by
P.E=


b.By using law of conservation of energy
P.E of spring=K.E of the pellet
K.E of the pellet=6.5025 J
Answer:
D
Explanation:
What it means to be an autotroph is that you make your own food and plants do that by photosynthesis to be a heterotroph is finding food from other sources like autotrophs or even other heterotrophs
