<u>Answer</u>
81.94 m
<u>Explanation</u>
The centripetal force of an object moving in a circular path is given by:
F = mv²/r Where m is the mass of the object, v is the constant velocity and r is the radius of the curve.
F = mv²/r
3,300 = (1600×13²)/r
3,300 = 270,400/r
r = 270,400/3,300
= 81.94 m
Answer:
The fluids speed at a) 
and b) 
are 
and 
respectively
c) Th volume of water the pipe discharges is: 
Explanation:
To solve a) and b) we should use flow continuity for ideal fluids:
(1)
With Q the flux of water, but Q is 
using this on (1) we have:
(2)
With A the cross sectional areas and v the velocities of the fluid.
a) Here, we use that point 2 has a cross-sectional area equal to 
, so now we can solve (2) for 
:
b) Here we use point 2 as 
:
c) Here we need to know that in this case the flow is the volume of water that passes a cross-sectional area per unit time, this is 
, so we can write:
, solving for V:
Answer:
38.77 kg
Explanation:
The weight of an object is given by:
Weight = mg, g = acceleration due to gravity ( 9.8 m/s square)
and m is the mass.
So, in this case:
Weight of dog is 382 N, so, by putting the values of weight and g into the equation we will get the mass of dog.
382 = mass multiply with 9.8
so, the mass of the dog will be 38.77 kg
Answer:
I belive it would be the first answer choice.
Explanation:
When the Mass is lower, the ball moves faster so it would have more kintetic energy
