❤️❤️❤️when we push a huge rock with all our might and fail to move it so where is the energy that we are spend gone??? ❤️❤️❤️Explain in at least 40 words minimum please❤️❤️❤️i will mark as brainliest​

Answer»

rgy U SPENT is changed into thermal energy. In simple HEAT. Even though the object fails to MOVE the energy u spent by breaking ATP bonds in ur muscle the heat is generated and is escaped into atmosphere in the form of sweat. dU = dQ + dWsince the object fails to move the work DONE is also ’0’. So it is clear that there is a CHANGE in internal energy which is equal to change in heat energy. Hope it helps!!!

What should be the angle if we want to throw an object to the maximum distance ?​

Answer»

The sine function reaches its largest output value, 1, with an input angle of 90 DEGREES, so we can SEE that for the longest-range PUNTS 2θ = 90 degrees and, therefore, θ = 45 degrees. A projectile, in other words, travels the farthest when it is LAUNCHED at an angle of 45 degrees.please follow me

What will you do to generate an emf in the solenoid?​

Answer»

A FLUX can induce EMF in a solenoidExplanation:A solenoid with a changing current RUNNING through it will generate a changing MAGNETIC field. This changing magnetic field is then captured by the very solenoid that created it. A captured field is called flux and a changing flux generates an emf — in this CASE, a self-induced or back emf.Explanation:

What do you mean by derive quantity ? Write any four derive quantity.​

Answer»

Derived QUANTITIES The PHYSICAL quantities that DEPEND upon other physical quantity for its measurement are known as derived quantities. The measurement of derived quantities directly depends upon other quantities. So in ORDER to measure the derive quantity, one must measure the quantities that it depends upon. Except 7 fundamental quantities, all other quantities are derived quantities. Some examples of derived quantities are: Acceleration ⇒ Density⇒ Pressure⇒ Potential Difference⇒ HOPE IT HELPS !!!

in this question I know that the energy transfer is taking place ..but I don't know that where the energy gone... so please tell​

Answer»

If only internal forces are doing WORK (no work done by EXTERNAL forces), then there is no change in the total amount of mechanical energy. The total mechanical energy is said to be CONSERVED. ... In these situations, the sum of the KINETIC and potential energy is everywhere the same.

Pledge for eye donation). Q.24. Pavni's mother had just washed all the white clothes. She was telling her friend that the whiteness ofwhite clothes was decreasing with every wash and even new white clothes appeared to be like old onesafter a few washings. Pavni, who is a student of class 10, was listening to her mother's complaint. Pavnithen went to the market and purchased a particular 'dye'. She asked her mother to dissolve a little of thisdye in a bucketful of water and soak the washed white clothes in the solution of dye for some time.Pavni's mother did the same. After sometime, the clothes were taken out of the bucket, rinsed well andspread on clothes line for drying. Pavni's mother observed that the whiteness of washed white clotheshad increased a lot after applying a little of the dye. Pavni's mother did not know why on applying alittle of a certain dye to washed white clothes, their whiteness had increased manifolds. Pavni explainedeverything to her mother.(a) What could be the 'dye' applied by Pavni's mother to the washed white clothes by dissolving in water?(b) Why does the application of this dye make the washed white clothes look even more white (or shiningwhite) ? Explain.(c) What values are displayed by Pavni in this episode ?​

Write a note on classification of errors​

Answer»

ication of Errors :Errors are normally classified in three categories: systematic errors, random errors, and blunders. Systematic Errors :Systematic errors are due to identified CAUSES and can, in principle, be eliminated. Errors of this TYPE result in measured values that are consistently too high or consistently too low. Systematic errors may be of four kinds:1. Instrumental. For example, a poorly calibrated instrument such as a thermometer that reads 102 oC when immersed in boiling water and 2 oC when immersed in ICE water at atmospheric pressure. Such a thermometer would result in measured values that are consistently too high.2. Observational. For example, parallax in reading a meter scale. 3. Environmental. For example, an electrical power ìbrown outî that causes measured currents to be consistently too low. 4. Theoretical. Due to simplification of the model system or approximations in the equations describing it. For example, if your theory says that the temperature of the surrounding will not affect the readings taken when it actually does, then this factor will introduce a source of error. Random Errors Random errors are positive and negative fluctuations that cause about one-half of the measurements to be too high and one-half to be too low. Sources of random errors cannot always be identified. Possible sources of random errors are as follows: 1. Observational. For example, errors in judgment of an observer when reading the scale of a measuring device to the smallest division.2. Environmental. For example, unpredictable fluctuations in line voltage, temperature, or mechanical vibrations of equipment. Random errors, unlike systematic errors, can often be quantified by statistical analysis, therefore, the effects of random errors on the quantity or physical law under investigation can often be determined. Example to distinguish between systematic and random errors is suppose that you use a stop watch to measure the time required for ten oscillations of a pendulum. One source of error will be your reaction time in starting and stopping the watch. During one measurement you may start EARLY and stop late; on the next you may reverse these errors. These are random errors if both situations are equally likely. Repeated measurements produce a series of times that are all slightly different. They vary in random vary about an average value. If a systematic error is also INCLUDED for example, your stop watch is not starting from zero, then your measurements will vary, not about the average value, but about a displaced value. Blunders A final source of error, called a blunder, is an outright mistake. A person may record a wrong value, misread a scale, forget a digit when reading a scale or recording a measurement, or make a similar blunder. These blunder should stick out like sore thumbs if we make multiple measurements or if one person checks the work of another. Blunders should not be included in the analysis of data. Hope this answer is helpful to you :D
