Here is the correct answer of the given problem above.
Given that the basket has a mass of 5.5kg, the magnitude of the normal force if the basket is at rest on a ramp inclined above the horizontal is at 12 degrees. The solution is simple: 
<span>Fn at rest = lmgl </span>
<span>= 5.5kg (9.80N/kg) 
=</span><span> mgCos12degrees 
Hope this answer helps. </span>

Answer:

(a) 53.9 N

(b) 52.72 N

(c) 48.85 N

(d) 38.11 N

Explanation:

The normal force is always perpendicular to the surface.

(a) the normal force = m x g = 5.5 x 9.8 = 53.9 N

(b) Normal force = m x g x CosФ = 5.5 x 9.8 x Cos 12 = 52.72 N

(c) Normal force = m x g x CosФ = 5.5 x 9.8 x Cos 25 = 48.85 N

(d) Normal force = m x g x CosФ = 5.5 x 9.8 x Cos 45 = 38.11 N

How can we realize that light travel in straight line ?​
Norma-Jean [14]

Answer:

It can be seen from the operation of pin-hole camera, formation of shadows and eclipse.

Explanation:

The phenomenon of light traveling in a straight line is known as rectilinear propagation of light.

One this evidence can be seen from the operation of pin-hole camera, which depends on rectilinear propagation of light

Also two natural effects that result from the rectilinear propagation of light are the formation of Shadows and Eclipse.

A car of mass 1500 kg is negotiating a flat circular curve of radius 50 m with a speed of 20 m/s.
Lilit [14]

Answer:

Explanation:

a. The source of centripetal force on the car is  (3) the static friction force.

b. ac = v²/R = (20²)/50 = 8 m/s²

c.  Fc = m(ac) = 1500(8) = 12 kN

d. μ = Fc/N = Fc/mg = 12000 / 1500(9.8) = 0.8163... ≈ 0.82
