Answer:We only Friction while accelerating or decelerating
Explanation:
This occurs because when we try to turn left or right , we are trying to change the velocity of car which in turns result in acceleration and finally change in force .
Change in force causes friction to vary and we experience the slipperiness of road.
Since temperature and kinetic energy of molecules are proportional, the more we increase the temperature of the solvent, the faster the solute will dissolve.
This increase of kinetic energy allows the solvent molecules to more effective break apart the solvent molecules that are held together by intermolecular forces.
The electric field in the conductor is 1. 96 × 10^-5 V/m
<h3>How to determine the drift velocity</h3>
The formula for drift velocity is expressed as;
Drift velocity = = μE
Where;
- μ is the Electron mobility of the material, copper wire = 40Vs
- E is the electric field
- Drift velocity = 7.84×10⁻⁴ m/s
Substitute the values
Electric field, E = Drift velocity/ electron mobility
E = 7.84×10⁻⁴/ 40
E = 1. 96 × 10^-5 V/m
Thus, the electric field in the conductor is 1. 96 × 10^-5 V/m

Answer:
39 square feet
Explanation:
The formula for figuring out the area of a triangle is base x height x 0.5 therefore each triangles area is 7.5 square feet x 4 which is 30 and the base of the pyramids area is equal to 9 square feet. 30 plus 9 equals 39 square feet.
