Creating new elements in order to study their properties is definitely pure research.
It has no earthly [known] application, since the elements don't even exist, whereas
for each of the other choices, you've stated the desired application as the reason
for the search.

Answer with Explanation:
We are given that
Force acts on a pebble= N
Position vector= m
a.We have to find the resulting torque on the pebble about origin.
Torque=
Substitute the values then we get
Torque=N-m
By using
b.
Torque about point (2,0,-3)
N-m
Answer:
0.75 m³/s
Explanation:
Applying,
Q = vA.................... Equation 1
Where Q = flow rate of the water, v = velocity of the water, A = area of the pipe.
From the question,
Given: v = 2.5 m/s, A = 0.3 m²
Substitute these values into equation 1
Q = 2.5(0.3)
Q = 0.75 m³/s
Hence the flow rate of water in the pipe is 0.75 m³/s
Answer:
10,000
Explanation:
200,000/20 = power needed
200,000/20 = 10,000
Hope this Helps!
