Answer: The Sun is present in the center of solar system whose features are color, mass and texture.
Explanation:
Our solar system consists of one star and 8 planets. The star is present in our solar system is the Sun and due to this star only, our solar system is named as such.
The planets present in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
These planets revolve around the star which is present at the center of the solar system.
Three physical features of Sun are:
- Color: The color of Sun is yellow.
- Mass: The mass of the Sun is
- Texture: Due to the convectional currents, the texture of the whole surface of sun is granular.
Hence, the Sun is present in the center of solar system whose features are color, mass and texture.

Answer:
The area is 2.5 m²
Explanation:
Step 1: Data given
A car has a 25 m² hydraulic lift platform that weighs 15000 N
The smaller piston required a force to lift = 1/100 its weight
Step 2: Calculate the area of the smaller piston
Pressure = Force / Area
F1 / A1 = F2 / A2
⇒ with F1 = weight of the hydraulic lift = 15000 N
⇒ with A1 = area of the hydraulic lift = 25 m²
⇒ with F2 = 1/100 of it's weight = 1500 N
A2 = F2 / (F1/A1)
A2 = 1500 ( 1500/25)
A2 = 2.5
The area is 2.5 m²

Radioactive elements are the unstable nuclei of the atoms that release energy and radiation. The atomic number remains the same in case of the gamma radiation.
What is gamma decay?
Gamma radiations are the particles that are released when the unstable atom undergoes decay and emits charged particles. These rays have no effect on the atomic mass and number of the atom.
These rays only emitenergy whereas alpha and beta decay produces energy and newparticle. An excited nucleus emits energy in the case of gamma decay that is unlike the other two decays.
Therefore, there is no change in the atomicnumber in gamma decay.

The light-gathering capacity of a telescope is dependent upon the:
magnification
focal length
size of human iris
area of aperture
Answers
Answer:
1) blue end of the spectrum
2) area of aperture
Explanation:
1) The electromagnetic spectrum encompases a wide range of frequency (ν) and wavelength (λ) that includes gamma rays, x-rays, ultra violet(UV), visible, infra red (IR), microwaves and radiowaves. The wavelength increases from gamma rays to radio waves.
The wavelength perceivable by human eyes lies in the UV-visible region which extends from 380 nm in the blue to 740 nm in the red.The shortest wavelengths occur in the blue end of the spectrum which also have the highest energy. In contrast, longer wavelengths occur on the red which have lower energy.
2) The light gathering capacity of a telescope is dependent upon its area of aperture. Larger the area, greater is the light gathering power which implies that the telescope has the capability of detecting weak or faint objects.
The area of the aperture is essentially the area of the objective of the telescopic lens which is given as:
where D = diameter of the lens
1) blue end of the spectrum
2) area of aperture
