A freely falling body has a velocity v after covering a height of h , what will b be the velocity after covering the height of 2h? With explanation please... |
|
Answer» Answer:hi there is your ans Explanation:Initial speed of the body u=0 Acceleration of the freely falling body a=g Velocity of body after covering h distance, v 1 =V Using v 1 −u 2 =2gh ∴ V 2 −0=2gh We get V 2 =2gh ....(1) LET the total distance COVERED by body to ATTAIN v 2 =2V be H. Using v 2 −u 2 =2gH Or 4V 2 −0=2gH Or 4V 2 =2gH Or 4(2gh)=2gH Thus we get H=4h Now REQUIRED distance the body needed to fall Δh=H−h ∴ Δh=4h−h=3h |

What is the difference between capacitance and permittivity |
|
Answer» Capacitance is the ratio of the change in ELECTRIC charge of a system to the CORRESPONDING change in its electric potential. ... For MANY DIELECTRIC materials, the permittivity and thus the capacitance, is independent of the potential difference between the conductors and the total charge on them. |

Define that ligth, reflection and refraction in short anwer with example |
|
Answer» Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the HUMAN eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometers, or 4.00 × 10⁻⁷ to 7.00 × 10⁻⁷ m, between the infrared and the ultraviolet. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. COMMON examples include the reflection of light, sound and water waves. In physics, refraction is the change in direction of a wave passing from one medium to another or from a GRADUAL change in the medium. Refraction of light is the most COMMONLY observed phenomenon, but other waves such as sound waves and water waves also EXPERIENCE refraction. |

What is density ? What is its S.I unit ? |
|
Answer» Answer: Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly EXPRESSED in UNITS of grams per cubic CENTIMETRE. Density can also be expressed as kilograms per cubic METRE (in MKS or SI units) |

Why mass of an object remaining constant everywhere? |
|
Answer» Answer: The WEIGHT of an object will change if the object is brought FARTHER away from Earth, or placed on a different planet, SINCE the force of gravity on the object will change. However the MASS of the object will remain the same regardless of WHETHER the object is on Earth, in outer space, or on the Moon. Explanation: follow me |

When we throw a ball upward why it comes down |
|
Answer» Explanation: Answer. When we throw a ball upwards, its speed retards gradually. This is because the earth PRODUCES a gravitational force which brings down everything that goes up. So when a ball is thrown upward the gravity applies force to BRING it down which decreases its speed of going up |

Impact of force produced on an object depends on |
|
Answer» A FORCE acting on an object causes the object to change its shape or SIZE, to START moving, to stop moving, to accelerate or decelerate. When there's the interaction between TWO objects they exert a force on each other, these EXERTED forces are equal in size but opposite in direction. |
