There are a few disadvantages, so let's start with the most simple. Night time, the sun isn't up so solar panels can't gather energy. Also, when it's snowing or raining or it's cloudy. Another thing is as of right now it's costly to get solar panels installed. Furthermore, a solar panel has to be maintained as in brushed cause debris can get caught on it and therefore block the sunlight. If you have anymore questions just comment and I will help further. I hope this helps!

If a car has a velocity of 85 km/hr, how long will it take to accelerate to 45 km/hr if the acceleration is -3 km/hr/sec?
weqwewe [10]

Answer:

Time, t = 13.34 seconds.

Explanation:

Given the following data;

Initial velocity, u = 85km/hr to meters per seconds = 85*1000/3600 = 23.61 m/s

Final velocity, v = 45km/hr to meters per seconds = 45*1000/3600 = 12.5 m/s

Acceleration, a = -3 km/hr/sec to meters per seconds square = -3*1000/3600 = -0.833m/s²

To find the time;

Acceleration = (v - u)/t

-0.833 = (12.5 - 23.61)/t

-0.833t = -11.11

t = 11.11/0.833

Time, t = 13.34 seconds.
