As acceleration is any change in the velocity
So when the all forces applied are balanced mean no net forces acting so it will not accelerate
so option D is correct  <span>apply balanced forces</span>
hope it helps

Light could be thought of as a stream of tiny particles discharged by _______ objects that travel in straight paths. *
Gelneren [198K]

Answer: Light could be thought of as a stream of tiny particles discharged by luminous objects that travel in straight paths.

Explanation:

We can define "radiation" as the transmision of energy trough waves or particles.

Particularly, light is a form of electromagnetic radiation, so the "tiny particles" of light are discharged by a radiating object, particularly we can be more explicit and call it a luminous object, in this way we are being specific about the nature of the radiation of the object.

What is the kinetic energy of an object that has a mass of 12 kg and moves with a velocity of 10 m/s
WITCHER [35]

Answer:

600 J

Explanation:

The formula to find the kinetic energy of an object is \frac{1}{2}mV^2

  • m = mass in kg
  • V = velocity in m/s
  • KE is measured in Joules just as all other forms of energy.

Now, let's plug in the variables we're given and simplify.

  • \frac{1}{2}(12)(10)^2
  • \frac{1}{2}(12)(100)
  • (6)(100)
  • (600)

Thus, the answer is 600 Joules.

The eye is actually a multiple-lens system, but we can approximate it with a single-lens system for most of our purposes. When t
hram777 [196]

Explanation:

Given that,

The optical power of the equivalent single lens is 45.4 diopters.

(a) The relationship between the focal length and the focal length is given by:

f=\dfrac{1}{P}

f=\dfrac{1}{45.4}

f = 0.022 m

or

f = 2.2 cm

(b) We need to find how far in front of the retina is this "equivalent lens" located. It is given by using lens formula as :

\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}

Here, u = infinity

\dfrac{1}{v}=\dfrac{1}{2.2}

v = 2.2 cm

So, at 2.2 cm in front of the retina is this "equivalent lens" located.

Hence, this is the required solution.
