Answer:
The quantitative method
Explanation:
<em>Quantitative method is the use of numbers, graphs, logic, tables, charts, stadistics, etc.</em> This kind of method is objective, can be replicated and repeated, and it collects numeric data.

Answer:
232 J/K
Explanation:
The amount of heat gained by the air = the amount of heat lost by the tea.
q_air = -q_tea
q = -mCΔT
q = -(0.250 kg) (4184 J/kg/ºC) (20.0ºC − 85.0ºC)
q = 68,000 J
The change in entropy is:
dS = dQ/T
Since the room temperature is constant (isothermal):
ΔS = ΔQ/T
Plug in values (remember to use absolute temperature):
ΔS = (68,000 J) / (293 K)
ΔS = 232 J/K
Work = (force) x (distance
28.4 joules = (force) x (4 meters)
Divide each side by (4 meters) :
Force = (28.4 joules) / (4 meters)
Force = 7.1 Newtons
Answer:
F = 755 N and h = 10.0 m and a = 9.8 m/s 2 and m=? and v = ?
Answer:
28.1 m/s
Explanation:
= Initial velocity of the fish = 1.52 m/s
y = Height of the bird = 40 m
= Acceleration in y axis = 
= Initial velocity in y axis = 0
The final velocity in x direction will remain the same as the initial velocity as there is no acceleration in the x direction 
Resultant velocity is given by
The fish is moving at a velocity of 28.1 m/s when it hits the water.
