Explanation:
de Broglie wavelength= h/mv
v=h/m x de Broglie wavelength
v= (6.626× 10^-34)/ (2347× 1.27 × 10^-38)
v= 22.229 m/s(according to Google scientific calculator)
am sorry I don't hv a calculator at hand
Solution:
To convert Celsius to Fahrenheit, the formula to be used is (C * 9/5) + 32
So in our given, 28.7 degrees Celsius:
Farenheit = (28.7 * 9/5) + 32
= 51.66 + 32
= 83.66 degrees Fahrenheit
Next, 35.5 degrees Celsius:
Farenheit = (35.5 * 9/5) + 32
= 63.9 + 32
= 95.9 degrees Fahrenheit
So in Fahrenheit, the range would be 83.66 – 95.9 degrees Fahrenheit.
Answer:
6.25% of the original amount
Explanation:
half-life means that half is gone for every certain period of time. Because the half life is 1 month, only half of the 'radionulide' is left every month.
after 1 month= 50%
after 2 months= 25%
after 3 months= 12.5%
after 4 months= 6.25%
Answer:
1)They breathe to air
2)They need nutrition to live
3)Their body is made up of cells
4)All living things respond to stimuli.
