Now build a model of salt. Use the blue, squarer marshmallows to represent the chlorine atoms and the pink, rounder marshmallows to represent the sodium atoms. Connect the marshmallows with toothpicks using the picture in part A as a guide. Drag each image to the correct location on the model. Each image can be used more than once.

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?

Explanation:

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
