You would want to include qualitative and quantitative evidence
Vas happenin!!!
Hope your day is good
I would say observational tool
Hope this helps

Answer:
4500 joules
Explanation:
since work(joules) = force(newtons) x distance(meters),
150N x 30M = 4500 Joules
Answer:
Groundwater occasionally discharges into surface water and then, they flow together as a body of water in a watershed.
Explanation:
According to www.mbgnet.net A watershed describes an area of land that contains a common set of streams and rivers that all drain into a single larger body of water, such as a larger river, a lake or an ocean.
Therefore, when groundwater discharges into a body of surface water, for example a stream, the stream just like several other streams in a watershed would flow into a larger body of water.
1. Frequency: 
The energy given is the energy per mole of particles:
1 mole contains a number of Avogadro of particles, 
, equal to
particles
So, by setting the following proportion, we can calculate the energy of a single photon:
This is the energy of a single photon; now we can calculate its frequency by using the formula:
where
is the Planck's constant
f is the photon frequency
Solving for f, we find
2. Wavelength: 
The wavelength of the photon is given by the equation:
where
is the speed of the photon (the speed of light). Substituting,
