Answer:
11.98 N
Explanation:
Normal force = mg = 2.03 * 9.81
coeff of static friction must be overcome for the book to begin moving
.602 = F / (2.03 * 9.81) = 11.98 N
Answer:
KE + PE = KE + PE
Explanation:
In a closed system, the mechanical energy of the system is constant.
Mechanical energy is given by the sum of kinetic energy and potential energy; mathematically:
U = KE + PE
where
KE is the kinetic energy
PE is the potential energy
This means that if we consider two situations, one at the beginning and one at the end, the value of U will not change if the system is closed; this means that the sum KE + PE will remain the same, so we can write:
KE + PE = KE + PE
I am pretty sure it is False because qualative data includes things you can't measure usually containing your 5 senses
Explanation:
It is given that,
Voltage, 
De broglie wavelength in terms of voltage is given by :

m and e are the mass and charge on electron. So,



So, the De broglie wavelength of an electron is 1.53 meters. Hence, this is the required solution.
