Answer:
A mass of 4 Kg rest on the horizontal plane. The plane is gradually inclined until at an angle of θ=15
∘
with the horizontal,the mass just being to slide what is the coffeficient of static friction between the block & the surface.
Explanation:
Answer:
stryo: 1
wood: 1
ice: 1
brick: 2
aluminum: 2.7
Explanation:
d= mass/ total volume
(fyi: for aluminum, they did the subtraction wrong to find the total volume. it is actually 5 or 5.00)
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.

Expalantion</h2>
In the ancient time, the scientists believed that there is the smallest particle which can control the nature of reaction in the environment which they called them. Then a lot of experiment was conducted in which new coming scientists discovered the protons, electrons, neutrons, and other smallest particles. Firstly, scientists performed experiments for this new discoveries to know better about them and then include them in their next experiment for better exposures.
