Answer:
1.33 cm
Explanation:
L = 32 m, T 1 = 0 degree C , T2 = 32 degree C
Thermal expansion coefficient of steel, α = 13 x 106-6 per degree C
Let ΔL be the increase in length.
ΔL = L x α x ΔT
ΔL = 32 x 13 x 10^-6 (32 - 0)
ΔL = 0.0133 m = 1.33 cm
Let's mention 2 examples of a mixture:
1) blood- blood is a mixture of blood plasma and blood cells. Blood is very important to many forms of life, including humans. It's therefore essential to living things!
2) ocean water! it's also a mixture and it covers a great portion of the Earth.
Let us assume f(x) = 2x - 5
f⁻¹(x) = (x + 5)/2
f(f⁻¹(x)) = 2((x + 5)/2) - 5 = x
f⁻¹(f(x)) = (2x - 5 + 5)/2 = x
The domain of a function is the range of its inverse and vice versa
The range of a function is the domain of its inverse and vice versa
Therefore, statements A, B, D and E are true
Answer:
(B) 1.6 m/s^2
Explanation:
The equation of the forces acting on the box in the direction parallel to the slope is:
(1)
where
is the component of the weight parallel to the slope, with m = 6.0 kg being the mass of the box, g = 9.8 m/s^2 being the acceleration of gravity, 
being the angle of the incline
is the frictional force, with 
being the coefficient of kinetic friction, N being the normal reaction of the plane
a is the acceleration
The equation of the force along the direction perpendicular to the slope is
where 
is the component of the weight in the direction perpendicular to the slope. Solving for N,
Substituting into (1), solving for a, we find the acceleration:
