They all Increase friction, when you are stopping the shoe or car is creating friction so you are able to stop.
Tire treads, rubber mats, automobile brakes an tennis shoes increase friction. They prevent from slipping by increasing friction.
Tire treads, rubber mats, automobile brakes, and tennis shoes all increase friction. This increased friction helps improve grip and control, enhancing safety and performance in activities like driving and sports. Therefore, the correct answer is C: They increase friction.

Untuk menghitung efisiensi sebuah rectifier, kamu bisa pakai rumus efisiensi (η) berikut:[tex]\text{Efisiensi} = \left( \frac{\text{Daya Output}}{\text{Daya Input}} \right) \times 100\%[/tex]Diketahui:Input (masukan) = 1500 wattOutput (keluaran) = 1200 wattHitung:[tex]\eta = \left( \frac{1200}{1500} \right) \times 100\% = 0{,}8 \times 100\% = 80\%[/tex]Jawaban:Efisiensi rectifier tersebut adalah 80%Artinya, 80% dari energi input diubah menjadi output, sedangkan sisanya (20%) hilang sebagai panas atau rugi-rugi lain.
