Excessive vibrating at low RPM can be caused by worn-out engine mounts. These pieces mount the engine to the frame of the vehicle, and when they wear out, the engine can literally lift and shift out of place when the car is running
There is no next number because numbers are infinitely dense. The next positive integer is 2100.
80% of 2100 = 80% * 2100 = 0.8 * 2100 = 1680
ANSWER: 1055% of 2100= 5% * 2100= 0.05 * 2100= 105
7% of 2100 = 7% * 2100 = 0.07 * 2100 = 147

This can happen when the engine isn't running on all cylinders and the torque clutch converter is engaged. Changing the engine's running parameters will cause the torque clutch converter to disengage and the transmission is then fluid-coupled which even out (masks) the engine vibration. Not sure what vehicle you have but bad universal joints in the drive shaft can also cause that.

1/3 * 2100 = 2100/3 = 700
110% of 2100 = 2100*110/100 = 2310
