La vitesse augmente considérablement la gravité des blessures en cas d'accident. Ainsi, le risque d'être gravement blessé ou tué lors d'un impact double entre 50 et 70 km/h et quadruple entre 70 et 90 km/h.

What do you mean there’s no jelly beans

The answer is as follows in the photo

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
