Explanation:
It is given that,
Length of the poster, l = 0.95 m
Breadth of the poster, b = 1 m
The poster is in the shape of rectangle. For a rectangular shape, perimeter is equal to :
P = 2(l+b)
P=2(0.95+1)
P=3.9 m
(b) One digits, P = 4 m
(c) Two digits, P = 3.9 m
(d) Three digits, P = 3.90 m
Combustion is and example of an oxidation reaction to burning/high energy conversion.
Answer:
Explanation:
Let magnetic force F acts towards right and the string makes an angle of θ with the vertical in equilibrium .Let T be tension in equilibrium
T cos θ = mg
T sin θ = F
Dividing
Tan θ = F / mg
F = mg Tanθ
= 51.5 x 9.8 x 10⁻³ x 26 / 20.8 Tanθ = 26 / 20.8 )
= 630.875 X 10⁻³ N
Each electron winds up with kinetic energy of
(270 keV)
plus
(whatever KE it had when it started accelerating).
