Answer:
Part a)
Part b)
Explanation:
Part a)
mass of the Falcon bird is given as
initial speed of the bird is
final speed of the bird is given as
(opposite direction)
So here the impulse given by falcon bird is given as
now the final momentum of Raven bird in perpendicular direction is given as
now the change in the angle of the raven bird is given as
Part b)
Final speed of the raven bird is given as
Propeller
Fluid
Turbine
Mechanical energy
Eléctrica energy
Answer:
The potential energy decreases
Explanation:
- When a proton moves in the direction of the electric field, the force on the proton (f=qE) will be in the direction of the field.
- The proton will accelerate and the KINETIC energy will increase.
- The potential energy decreases.
The ideal spring equation is
Stretch = K times Force .
This says that the stretch is directly proportional to the force.
In simple English, that means that if you double the force, then
you double the stretch, and if you multiply the force by π or
any other number, you multiply the stretch by the same number.
So you can always write a proportion for a spring:
Stretch₁ / Force₁ = Stretch₂ / Force₂ .
Part A:
In Part-A of this question, the force is increased to (2.5 / 2.0) = 1.25 times .
So the stretch is also increased to 1.25 times .
(1.25) x (6.1 cm) = 7.625 cm .
