Line - A:  (15/10)  =  1.5 inch/second

Line - B:  (0/10)  =  0

Line - C:  (10/10)  =  1.0 inch/second

Line - D:  (-25/20)  =  -1.25 inch/second

<em>Line-A</em> represents the greatest speed.

A 2. 0 kg-book is at rest on a 30 o inclined plane. The normal force acting on the book by the inclined plane is most nearly
Anvisha [2.4K]

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 circumference of a circle is 12π meters. find the​ circle diameter.
Veseljchak [2.6K]
The circumference of a circle is 2*pi*r=C so plugging in numbers we have
12pi= 2*pi*r so solving for r gives 12pi/2pi=r which gives 6=r so the radius of the circle is 6 meters since diameter is just 2*r this gives 2*r =12 meters so
Diameter = 12meters

The electric field strength E is measured as:
soldi70 [24.7K]
The correct answer is
<span>force per unit charge.

In fact, the electric field strength is defined as the electric force per unit charge experienced by a positive test charge located in the electric field. In formula:
</span>E= \frac{F}{q}
where
E is the electric field strength
F is the electric force experienced by the charge
q is the positive test charge.

The sound level near a noisy air conditioner is 70 dB. If two such units operate side by side, the sound level near them would b
Schach [20]

Answer:

73 db

Explanation:

A single air conditioner is equivalent to 70 dB frequency. An extra air conditioning unit would therefore double the sound frequency. It does not, however, double the decibels to 140 dB. Instead, it adds only 3 dB to the 70 dB, making the total decibels of two air conditioning units equal to 73 db

Hence the correct option is b that is 73 db
