Answer:
The distance the mass would stretch it is
The correct option is A
Explanation:
From the question we are told that
The period of the slit is
The acceleration due to gravity is
Generally the period is mathematically represented as
Whee m is the particle and k is the spring constant
making the subject
The weight on the particle is related to the force stretching the spring by this mathematical relation
where x is the length by which the spring is stretched
Substituting the equation above for
making x the subject
Substituting the value
Answer: If a velocity time graph is horizontal then the velocity is constant and there is no acceleration.
Solid like a ice cube
Liquid like water
Gas=water vapor orHelium

What is Lens?
A lens is a transmissive optical tool that uses refraction to focus or disperse a light beam. A compound lens is made up of multiple simple lenses (elements), typically arranged along a common axis, as opposed to a simple lens, which is one solid piece of transparent material. Glass or plastic are used to make lenses, which are then polished or moulded into the desired shape. In contrast to a prism, which simply refracts light without focusing it, a lens can focus light to create an image. Lenses are also devices that focus or disperse waves as well as radiation other than visible light, such as <u>explosive lenses, microwave lenses, particle lenses, and acoustic lenses</u>.
Lenses are a common component of <u>telescopes</u><u>, binoculars, and cameras, among other imaging devices</u>.

The answer is 54.675 J
<span>The kinetic energy (Ke) of an object is the product of half of its mass (m) and the square of its velocity (v²):
</span>Ke = 1/2 m * v²
We have:
Ke = ?
m = 15 kg
v = 2.7 m/s
_____
Ke = 1/2 * 15 kg * (2.7 m/s)² = 1/2 * 15 kg * 7.29 m²/s² = 54.675 kg * m²/s²
Ke = 54.675 J
