The normal force acting on the book by the inclined plane is most nearly 17N.
<h3>What is the normal force?</h3>
When a body is resting on the surface, the reaction force acting perpendicular to the surface of contact and in upward direction is equal to the the weight of the object.
On an inclined plane of 30 degree, a 2 kg block is resting. Its weight mg has two components, mgcos30 and mgsin30.
The Normal force will be equal to
N = mgcos30
N =2 x 9.81 x cos30
N = 17 Newtons
Thus, normal force acting on the book by the inclined plane is most nearly 17N.

The portable tank should be connected to earth to neutralise rhe charges to prevent sudden discharge which may cause sparks and lead to fire.
First determine the net force. Let's say the downwards force is negative and the upwards force is positive.
Since the forces act in opposite directions, the net force would be:
400N - 600N = -200N
Since I said negative is downwards, this translates to the net force being 200N downwards.
Force = mass*acceleration
200N = 60kg * acceleration
acceleration = 3.33 m/s^2

Answer:
The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4o C to 0o C, and it becomes less dense. The density is maximum at 4 degree centigrade and decreases below that temperature as shown in graph.
