Justify |
|
Answer» Answer: find the speed of the CAR between 12:00 HOURS to 12:30 hours time = 12:30 - 12:00 = 30 mins = 1/2 hr Distance = 65-30 = 35 km average speed = distance/ time taken = 35/(1/2) = 70 km/hr what is the average speed of the car total time = 1:00 pm = 13:00 - 11:00 = 2 hrs distance = 100 km speed = 100/2 = 50 km/ hr is the car's motion is an EXAMPLE of uniform motion No ist 1/2 hr 60 km/ hr 2nd 1/2 hr 0 km/ hr next 2 1/2 hrs 70 km/ hr Explanation: Please FOLLOW me and like please |

Inertia is a scalar or a vector quantity, justify |
|
Answer» Answer: Hi your answer is as follows Explanation: Moment of Inertia is a tensor quantity which MEANS it behaves as scalar and sometimes it behaves as vector quantity Reason : Moment of inertia is the property where body resists change in its STATE of rotatory motion. Inertia is a measure of mass so it is scalar quantity. But an object in rotatory motion will change its direction every point to point . HENCE it is also vector quantity.

What is The 3 laws of newton? |
|
Answer» the three laws of Newton is In the first law, an object will not change its MOTION unless a force ACTS on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply FORCES to each other of equal MAGNITUDE and opposite direction. |

What is inside a black hole ???? How black holes appear ???? |
|
Answer» Answer: Black HOLES are generally defined as "a place in space where gravity PULLS so much that even light cannot GET out. The gravity is so strong because [the] matter has been squeezed into a tiny space." ... As light is UNABLE to escape the hole's gravity it APPEARS completely black - hence the name. |
