The <span>physical properties of non-metals are as below:
1) Poor conductors - generally non-metals are poor conductors of heat and electricity.
2)Low melting points - all metals have low melting and boiling points, with graphite being an exception.
3) Brittle - all nonmetals are brittle in nature.</span>
Answer:
B=1.04*10^{-4}T
Explanation:
An infinite wire produces a magnetic field that can be computed with the formula:

where m0 is the magnetic permeability of vacuum (4pi*10^{-7}Tm/A), I is the current of the wire (2.50A) and r is the perpendicular distance to the wire in which B is calculated (3cm=3*10^{-2}m). By replacing we obtain:

The angle above the horizontal of the motion of mass A + B after the collision. as well as others are mathematically given as

- vf/vA= 0.94
- 2vf^2 / 5vA^2 = 0.35
<h3>What is
Collison equilibrium?</h3>
According to the collision hypothesis of chemistry, chemical reactions happen when two molecules or atoms collide.
Generally, the equation for Collison equilibrium is mathematically given as
For horizontal motion
mvAx+m2vAx = 2mvfx
For vertical motion
-mvAy+m2vAy = 2mvfy
vfy = 1/2 vAy


(b)

vf/vA= 0.94
(c)
![Ef/Ei = \frac{(1/2 * (2m) * (vf)^2) }{ (1/2 * m * (vA)^2) + 1/2*m*(2vA)^2) ]}](https://tex.z-dn.net/?f=Ef%2FEi%20%3D%20%5Cfrac%7B%281%2F2%20%2A%20%282m%29%20%2A%20%28vf%29%5E2%29%20%7D%7B%20%281%2F2%20%2A%20m%20%2A%20%28vA%29%5E2%29%20%2B%201%2F2%2Am%2A%282vA%29%5E2%29%20%5D%7D)
2vf^2 / 5vA^2 = 0.35
In conclusion, The angle above the horizontal of the motion of mass A + B after the collision. as well as others

vf/vA= 0.94
2vf^2 / 5vA^2 = 0.35

All waves do carry energy. True.
Answer:

Explanation:
Energy and mass are related by the famous equation developed by Albert Einstein:

where m = mass and c = speed of light
This equation explains that an object with very small mass can produce a large amount of energy in reactions such as a nuclear reaction.
Hence, the energy produced by the explosion of a Plutonium bomb containing 3.6 grams of matter is:

E =
