Scattering occurs when light changes direction after colliding with particles of matter.
Answer:
The rate at which energy is transferred is called power and the amount of energy that is usefully transferred is called efficiency.
A defective protein would be produced leading to either that protein cell being killed or developing into a cancer
Answer:
Work done by the gardner is 500 J
Explanation:
As we know that the gardner apply force perpendicular upward by magnitude 300 N and along the floor horizontal force is 100 N
so we have
now the displacement of the gardner along the floor is
now work done is given as
so we have
Answer:
t = 39.04 1010 year
Explanation:
This is a nuclear disintegration exercise that is governed by the equation.
N = N0 e (-lam t)
The average life time is related to nuclear activity
T ½ = ln 2 / lam
Let's use these two equations for exercise, let's start by finding nuclear activity
Lam = ln 2 / T ½
Lam = ln 2 / 4.9 10 10
Lam = 0.14146 10-10 y-1
They tell us that the relationship atoms
No / N = 0.0040
Let's look
No / N = 1/0040
N/No = 250
Let's calculate the time
(-lam t) = ln (N / No)
, t = - 1 / lam ln (n / No)
t = - 1 / 0.14146 10-10 ln (250)
t = 39.04 1010 year
