Answer:
Equal
Explanation:
The law of conservation of energy states that the total momentum before and after a collision are equal
<span>This projectile has been thrown in an oblique movement, so it’s moving in x and in y at the same time. Vy varies due to gravity, and Vx is a constant as there is no gravity in the horizontal direction. In order to calculate Vx, you have to use the angle:
Vx=V*cosa=12m/s*cos(14.2)= 11.6m/s
So now you should use Vx the same way it is used in a uniform linear movement.
d=v*t
dx=vx*t
t=dx/vx=7m/(11.6m/s)=0.603s</span>
P = U × I
I = P / U = 1600W / 120V = 13.4A
P = 240V × 13.4A = 3216W
If your hair blower isnt rated for 220- 230V(this is the voltage in EU) you are most likely going to burn it.
Answer:
cation, anion
Explanation:
Binary Ionic Compounds- Binary means 2, ionic relates to charges. Therefore binary ionic compounds have TWO elements, with charges that cancel eachother out. The cation (or positive charge) goes before the anion (or negative charge)
example:
NaCl
Na^+1
Cl^-1
Sodium Chloride
