Answer:2

Explanation:

Given

Velocity of bicycle is 5 m/s towards north

radius of rim r=20 cm

mass of rim m=2 kg

Angular momentum \vec{L}=I\cdot \vec{\omega }

I=mr^2=2\times 0.2^2=0.08 kg-m^2

\omega =\frac{v}{r}=\frac{5}{0.2}=25 rad/s

L=0.08\times 25=2kg-m^2/s  

direction of Angular momentum will be towards west

Hole filling fasteners (for example, MS20470 rivets) should not be used in composite structures primarily because of the?
DIA [1.3K]

Answer:

We can cause delamination.

Explanation:

The reason why is because the probability of causing delamination increase considerably when we use Hole-filling fasteners. If we use a typical rivet, these tends to expands in order to fill the hole.

If we analyze the force applied by the expanded rod will cause that the matrial will be deteriorated and will cause that the material to delaminate around the edges of the hole and we can cause possible control and no protection to the material.

The drag force pushes opposite your motion as you ride a bicycle. If you double your speed, what happens to the magnitude of the
aksik [14]

Answer:

Option A

The drag force goes up by a factor of 4

Explanation:

Fact:

Drag force is directly proportional to the square of the velocity of a moving object

Therefore, when drag force pushes opposite to the motion as one rides a bicycle, the magnitude of drag force increases by a factor of 4

What's drude and Lorenz theory?​
denis23 [38]

Answer:

When an electric field is established across the metallic solid, the free electrons are accelerated. ... Thus, an electron acquires additional non-random velocity opposite to direction of field. This velocity is responsible for transport of electrons in conductors.
