A person on a road trip drives a car at different constant speeds over several legs of the trip. She drives for 10.0 min at 50.0 km/h, 19.0 min at 100.0 km/h, and 60.0 min at 55.0 km/h and spends 40.0 min eating lunch and buying gas. What is the average speed for the entire trip (

It is given that for different time span car have different speed and also the person spend in eating lunch and buying gas.

We know , average speed is total distance covered by total time taken .

Therefore , average speed ,

Hence, this is the required solution.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
