Answer: 20 pm=20*10^-12 m
Explanation: To solve this problem we have to use the relationship given by:
λmin=h*c/e*ΔV= 1240/60000 eV=20 pm
this expression is related with the bremsstrahlung radiation when a flux of energetic electrons are strongly stopped hitting to a catode. The electrons give their kinetic energy to the atoms of the catode.
The number of kilowatts used by an individual to operate his appliances is determined as 12.1 kWh.
<h3>
Average daily power consumption</h3>
The average daily power consumption is the amount of electric energy consumed by an individual on a daily rate.
The average daily power consumption of individuals in USA is 12,100 W-hr.
<h3>Converting watts to kilowatts</h3>
E = 12,100 Whr/1000
E = 12.1 kWh
Thus, the number of kilowatts used by an individual to operate his appliances is determined as 12.1 kWh.

A) <u>Weight = mass × acceleration (due to gravity) </u>
= 60×9.8
= 588 N
<u>B) Potential energy = mass x gravity x change in height
</u>
1,000 = 60.0 x 9.8 x h
h = 1.7 m
<u>C) Kinetic energyF = potential energyI
</u>
KEF = 1/2mv2
PEI = mgh = 1,000 J
1/2mv2 = 1,000
1/2(60.0)v2 = 1,000
v2 = 33.33
v = 5.77 m/s
Answer:
A) Amplitude
Explanation:
The angular frequency ω = √k/m
maximum acceleration = ω²A ; A is amplitude
frequency of oscillation = ω / 2π
maximum force = m x ω²A
so maximum acceleration ,frequency of oscillation and maximum force
all depend on ω so they will change due to change of mass . Hence amplitude will remain constant.
Answer: The salinity of freshwater is 0.5 ppt, the salinity of salt water is 35 ppt.
The freezing point point of fresh water is 32 degrees Fahrenheit, the freezing point of salt water is 28.4 degrees Fahrenheit.
The distribution of fresh water on earth is 3%, the distribution of salt water is 97%.
Fresh water is found in glaciers, underground, lakes, rivers, and swamps, salt water is found in oceans.
