Why are the alkali metals likely to react with group 17 elements?

Physics

Answer:

Because alkali metals are so reactive, they are found in nature only in combination with other elements. They often combine with group 17 elements, which are very “eager” to gain an electron.

A pendulum consists of a 2.0-kg block hanging on a 1.5-m length string. A 10-g bullet moving with a horizontal velocity of 900 m
pav-90 [236]

Answer:

The maximum height above its initial position is:

h_{max}=1.53\: m

Explanation:

Using momentum conservation:

m_{b}v_{ib}=m_{B}v_{fB}+m_{b}v_{fb} (1)

Where:

  • m(b) is the mass of the bullet
  • m(B) is the mass of the block
  • v(ib) is the initial velocity of the bullet
  • v(fb) is the final velocity of the bullet
  • v(fB) is the final velocity of the block

Let's find v(fb) using equation (1)

m_{b}(v_{ib}-v_{fb})=m_{B}v_{fB}

v_{fB}=\frac{m_{b}(v_{ib}-v_{fb})}{m_{B}}

v_{fB}=\frac{0.1(900-300)}{2}

v_{fB}=30\: m/s

We need to find the maximum height, it means that all kinetic energy converts into gravitational potential energy.

\frac{1}{2}m_{B}v_{fB}=m_{B}gh_{max}

h_{max}=\frac{1}{2g}v_{fB}

h_{max}=\frac{1}{2(9.81)}30

h_{max}=1.53\: m

I hope it helps you!

List and describe three biological applications of electricity
mihalych1998 [28]

Before we dive into how electricity is used around the home it is worth putting household electricity use in perspective.

Household electricity use generally makes up about a third of total electricity consumption  in most developed nations.  Using data from the European Union we can give an example of how electricity demand is split among different sectors.

Dinosaurs’ skeletons can be distinguished from those of other reptiles by the structure of the hips and legs.
jeyben [28]
True, they had a hole in their hip socket that allowed them to run faster than other reptiles of their size at the time. As well as most reptiles besides reptiles had legs to the side, rather than under them like dinosaurs did.

Hope this helps!
