Answer:
<em>1.187 x 10^8 m/s</em>
<em></em>
Explanation:
the potential of the electric field V = 40 kV = 40000 V
the charge on an electron e = 1.6 x 10^-19 C
The energy of an accelerated electron in an electric field is given as
E = eV
E = 1.6 x 10^-19 x 40000 = 6.4 x 10^-15 J
This energy is equal to the kinetic energy with which the electron moves, according to the conservation of energy.
The kinetic energy = 
where
m is the mass of the electron = 9.109 x 10^-31
v is the speed of the electron.
Equating the energy, we have
6.4 x 10^-15 = 
6.4 x 10^-15 = 4.55 x 10^-31
= 1.41 x 10^16
= <em>1.187 x 10^8 m/s</em>
Answer:
B.) Genes are segments of DNA, which is packaged in chromosomes.
Explanation: trust the process.
BUDDY.
This is the answer :)))))
(a) 
The radiation pressure exerted by an electromagnetic wave on a surface that totally absorbs the radiation is given by

where
I is the intensity of the wave
c is the speed of light
In this problem,

and substituting
, we find the radiation pressure

(b) 
Since we know the cross-sectional area of the laser beam:

starting from the radiation pressure found at point (a), we can calculate the force exerted on a tritium atom:

And then, since we know the mass of the atom

we can find the acceleration, by using Newton's second law:

Answer:
answer 2 because the baseball has less mass then the 1st one
