How does lithiums position in the periodic table relate to its properties

Physics

Mariulka [41]3 years ago

Being in group one we know it has 1 valence electron, is highly reactive to halogens, and based on the fact it is in period 2 we know it has 2 energy levels, 1 being full. We know this because it applies to everything in group one except for the part about energy level which is based on period.

If the time of the impact in a collision is extended by 4 times ,how much does the force of impact change
Rama09 [41]
We know, I = F.Δt
As Δt is increased to 4 times, then, F would decrease to 4 times, in order to keep that impulse constant.

In short, Your force will change to 1/4th of it's initial value

Hope this helps!

You are bungee jumping from a bridge. Initially, while you are falling the slack bungee cord isn’t exerting any forces or torque
harina [27]

Answer:

he fall movement we see that both the force is different from zero, and the torque is different from zero.

When analyzing the statements the d is true

Explanation:

Let's pose the solution of this problem, to be able to analyze the firm affirmations.

When the person is falling, the weight acts on them all the time, initially the rope has no force, but at the moment it begins to lash it exerts a force towards the top that is proportional to the lengthening of the rope.

The equation for this part is

                 Fe - W = m a  

                 k x - mg = m a

As the axis of rotation is located at the top where they jump, there is a torque.

What is it

                Fe y - W y = I α

angular and linear acceleration are related

       a = α r

       Fe y - W y = I a / r

In the fall movement we see that both the force is different from zero, and the torque is different from zero.

When analyzing the statements the d is true
