The answer would be :People, animals, water & the wind.
The reason as to why these would be the answer is because the wind disperses seeds by blowing them through the air to different locations. The water washes the seed away to a location away from the parent. Animals disperse seeds, when they leave behind their waste and the seeds are in the waste. Lastly people disperse seeds in many ways, but one of them would be like throwing them into the grass, and ir planting them.
Answer:
Explanation:
For anyone in UsaTestPrep it is D) appoint church positions The "investiture struggle" of the 11th and 12th centuries that took place between Pope Gregory VII and King Henry IV symbolized the struggle between the church and state over who had the power to appoint church positions. Pope Gregory VII later excommunicated King Henry IV over this issue and it led to a weakening in the Holy Roman Empire therefore it is D.
Answer: 176.4 Joules
Explanation: Potential energy of a body is defined as the energy possessed by virtue of position.
Potential energy 
m = mass of the body = 6 kg
g = acceleration due to gravity = 
h = height of body = 3 m
Potential energy 
= 176.4Joules {
}
Answer:
The torque applied by the drill bit is T = 16.2 Nm and the cutting force of the drill bit is F = 33 N.
Explanation:
Given:-
- The diameter of the drill bit, d = 98 cm
- The power at which drill works, P = 5.85 hp
- The rotational speed of drill, N = 1900 rpm
Find:-
What Torque And Force Is Applied To The Drill Bit?
Solution:-
- The amount of torque (T) generated at the periphery of the cutting edges of the drilling bit when it is driven at a power of (P) horsepower at some rotational speed (N).
- The relation between these quantities is given:
T = 5252*P / N
T = 5252*5.85 / 1900
T = 16.171 Nm
- The force (F) applied at the periphery of the drill bit cutting edge at a distance of radius from the center of drill bit can be determined from the definition of Torque (T) being a cross product of the Force (F) and a moment arm (r):
T = F*r
Where, r = d / 2
F = 2T / d
F = 2*16.171 / 0.98
F = 33 N
Answer: The torque applied by the drill bit is T = 16.2 Nm and the cutting force of the drill bit is F = 33 N.
