A body of mass 10 kg moving at a height of 2 m, with uniform speed of 2 m/s. Its total energy is |
|
Answer» Kinetic energy= 1/2mv^2= 1/2*10*2*2=20joulePotential energy=mgh= 10*9.8*2= 196 jouleTotal energy= 196+20=216 joule Kinetic energy = 1/2 mv^2 = 10 × (2) ^2 /2 = 200 J. // Potential energy = mgh = 10 × 9.8 × 2 = 196 J. Therefore, total energy = 200 + 196 = 396 J. // |

| Answer» | |
| 2534. |
X is equals to 5tsquare+ 9t plus 4 call to 1 second instantaneous t=2 to t=4sec average |
|
Answer» Therefore, Vavg = 29 + 49 / 4 + 2 = 78/6 = 13 m/s.// X = 5t^2 + 9t + 4 = 5 (2t) + 9 = 10t + 9//Therefore, in 4 s, X = 49 m. In 2 s, X = 29 m. |

Multiplication errors |
|
Answer» Actual values* and these are*. Sorry for mistake if we have to find density, then the formula for density is mass per unit volume. d = m/vThe equation will be - DELTA d/d = DELTA m/m + DELTA v/vHere, DELTA d represents the error in density and d represents the actual value of density. Similarly, DELTA m means error in mass whereas m means actual mass and DELTA v means error in volume and v means actual volume. In these questions, 4 values are often given which are of mass and volumes including their errors.These values are written in the form of x + or - delta x where delta x is the error and x is the actual value.So, we can find the actual value of density by putting the actual valued of mass and volume given in the question in the formula density(d) = mass(m)/ volume (v). These is applicable to division and multiplication both. |
