A small object caring a charge of -5×10^-9c experiences a downward force of 10N when placed at certain point in an electric field. A. what is the electric intensity at that point. B. what would be the magnitude and direction of the force acting on an electron placed at that point. ( q= 1.6×10^-19)​

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

Agirl throws a ball. if the ball's acceleration is 12 m/sec/sec and its mass is 0.5 kg, how much force did the girl apply to the ball?
