A uniform motion along a straight path has no a acceleration. Why? |
|
Answer» Explanation: Who has told you this concept. Motion along a straight too have an acceleration, if there is an external unbalance force. Body moving with uniform velocity only has not an acceleration. It is so because to have an acceleration there should be change in magnitude of velocity or DIRECTION of velocity. And a body moving in straight line with changing SPEED has an acceleration.I HOPE IT HELPS YOU...PLEASE MARK ME BRAINLEST.. |

What is a thermal power |
|
Answer» Answer: A thermal power station is a power station in which heat energy is CONVERTED to electric power. In most, a steam-driven TURBINE converts heat to MECHANICAL power as an intermediate to electrical power. WATER is heated, turns into steam and DRIVES a steam turbine which drives an electrical generator. |

A 1 kg object is dropped from a building 10.0 m above the ground. What is its speed just before it hits the ground if the air resistance could be ignored?1 m/s14 m/scannot be determined9.9 m/s |
|
Answer» Answer: Here we know that we have to MEASURE the speed as m/s. so we have to CONVERT 1kg into 1000grams and 10 meter as 1000 cm. Now the speed is 1000grams/1000cm. =1m/s. Therefore we got the answer as the speed of the object is 1m/s. I hope you got your answer and UNDERSTOOD that. Thank you for giving me the opportunity to answer your question.

A close-coiled helical spring has a stiffness of 10 N/mm. Its length when fully compressed,with adjacent coils touching each other is 40 cm. The modulus of rigidity of the materialof the spring is 0.8x10 N/mm²(i) Determine the wire diameter and mean coil diameter if their ratio is 1/10. |
Answer» The VALUE of diameter is 20 cmExplanation:
Solution: Now d / D = 1 /10 Length of solid = n x d 400 = n x d n = 400 / d Now d^2 = 0.4 d^2 = 0.4 x 10^3 = 400 d = √400 = 20 mm = 2 cm D = 10 x 2 = 20 cm Thus the value of diameter is 20 cm
