As the speed of airplane is change due to jet stream
So the net speed is given as
now we can rearrange it as
now by the formula of vector difference we have
now plug in all values
so above is the speed of the plane
Answer:
the correct statement is 2. The solid plate will have the greater angular acceleration.
the correct phrase is 4. The plate with the hole has its mass distributed further out from the axis of rotation, which will increase its moment of inertia.
Explanation:
Newton's second law expression for rotational motion is
τ = I α (1)
where the torque is
τ = F r
in this case, as the discs have the same radius and the applied force is the same, the torque is the same on the two discs.
The moment of inertia is given by the expression
I =∫ r² dm
for bodies with high symmetry are tabulated
the moment of inertia for in disk solid is I₁ = ½ m R₂²
the moment for a disk with a hole I₂ = ½ m (R₁² + R₂²)
We can see that the moment of inertia of the disk with the hole is greater than the moment of inertia of the solid disk.
Let's use equation 1
α = τ/I
therefore the angular acceleration is lower for the body with the higher moment of inertia, consequently the solid disk has higher angular acceleration
the correct statement is 2
The reason is because the moment of inertia is higher for the hollow disk.
the correct phrase is 4
The answer is TRUE, batteries CAN supply a steady flow of electrons.
Sensory nerves detect senses like touch, see, smell stuff like that. Motor nerves gives the reaction from the brain after receiving the information from the sensory nerves. example of when you touch a hot water your sensory nerves brings the information and your react to by pulling your hand out of the water. hope it helps
