Answer:
Explanation:
The expression for the deBroglie wavelength is:
Where,
is the deBroglie wavelength
h is Planck's constant having value
m is the mass of electron having value
v is the speed of electron.
Given that v =
Applying in the equation as:
Answer:
The freshwater sources that are generally in continuous motion and follow a defined path are called streams and rivers.
If I were to improve the lab then I will make the following changes:
- The experiment aimed to observe and model the effects of rivers on erosion. So, I can make a virtual model of the river and can compare the velocity, gradients and volume of rivers.
- Comparison between the low and high factors listed can help in computing the effect of the powerful river on erosion.
- The high velocity. gradient and volume of the river will cause more erosion as it exerts more force.
- The low volume, gradient and velocity river will affect in a less manner on erosion.
Explanation:
thats all i know ( correct me if im wrong please)
Higher <span>C. higher than when the source is stationary</span>
Answer:
Explanation:
Na react with H2O to form NAOH
2 Na+2H2O....................2NAOH + H2
Ca react with water and form calcium hydroxide
Ca + 2H2O........................Ca(OH)2
Mg react with water and form Magnesium hydroxide
Mg +2H2O .........................Mg(OH)2 however this coating of mg(oh)2 prevent it from further reaction
Fe react with water and form ferric hydride
3Fe +H2O.......................2 FeH +FeO
copper do not react with water
