Photon energy is directly proportional to frequency. So if we
want to find the radiation with the greatest photon energy, we
should look for the waves with the highest frequency (shortest
wavelength). From the list of choices, that's 'gamma rays'.
Answer:
The statement is TRUE
Explanation:
computer programs like spreadsheets can be used to help organize and analyze data. Regression Analysis can be carried out in Excel to determine the relationship between two quantitative variables.
There’s nothing to answer to
Answer:
125.83672 seconds
Explanation:
P = Power of the horse = 1 hp = 746 W (as it is not given we have assumed the horse has the power of 1 hp)
m = Mass of professor = 103 kg
g = Acceleration due to gravity = 9.8 m/s²
h = Height of professor = 93 m
Work done would be equal to the potential energy
![W=mgh\\\Rightarrow W=103\times 9.8\times 93\\\Rightarrow W=93874.2\ J](https://tex.z-dn.net/?f=W%3Dmgh%5C%5C%5CRightarrow%20W%3D103%5Ctimes%209.8%5Ctimes%2093%5C%5C%5CRightarrow%20W%3D93874.2%5C%20J)
Power is given by
![P=\frac{W}{t}\\\Rightarrow t=\frac{W}{P}\\\Rightarrow t=\frac{93874.2}{746}\\\Rightarrow t=125.83672\ seconds](https://tex.z-dn.net/?f=P%3D%5Cfrac%7BW%7D%7Bt%7D%5C%5C%5CRightarrow%20t%3D%5Cfrac%7BW%7D%7BP%7D%5C%5C%5CRightarrow%20t%3D%5Cfrac%7B93874.2%7D%7B746%7D%5C%5C%5CRightarrow%20t%3D125.83672%5C%20seconds)
The time taken by the horse to pull the professor is 125.83672 seconds
Answer:B
Explanation:
Calculate speed using equation:V=S/t
S=980 km ------------ distance Boston-Detroit
t=2h --------------------- time
v=?
------------------------
V=S/t
V=980km/2h
V=490km/h
