<em>g</em> is the vector (6, 3), since it starts at the origin and terminates at the point (6, 3).
We can write this as a sum of the scaled unit vectors (1, 0) and (0, 1),
(6, 3) = (6, 0) + (0, 3)
where (6, 0) is the <em>x</em>-component of <em>g</em> and (0, 3) is the <em>y</em>-component. The lengths of these component vectors are clearly 6 and 3, respectively.
Answer:
normal force in the vertical direction = 400 N
static friction = 300
uS*N = 300
uS * 400 = 300
us = 0.75
dynamic friction or kinetic friction = 200
uK * 400 = 200
uk = 0.5
a) 0.75 b) 0.5
Answer: Geothermal energy is produced by the heat of Earth's molten interior. This energy is harnessed to generate electricity when water is injected deep underground and returns as steam (or hot water, which is later converted to steam) to drive a turbine on an electric power generator.

The correct answer = λ= 1.899*10^-34 m
Explanation:
Since,
Wavelength = λ = h / mv
Where h = Planck’s constant = 6.626*10^-34 Js
m = mass of golf ball = 45.9 g = 45.9*10^-3 kg
v = velocity of ball = 76.0 m/s
λ = wavelength= ?
Plug in the values we get:
λ= (6.626*10^-34) / ( 45.9*10^-3*76)
λ= 1.899*10^-34 m
