Explanation:

Answer from: homework1911

The safety contract will include basic lab safety guidelines such as:

Remove all flammable materials from the work station. Avoid leaving the heating set-up unattended. Fold long sleeves, tie back long hair, remove all accessories that may catch on fire. Wear proper lab attire.Avoid horse-playing in the lab.Report any injuries to the teacher, no matter how minor, as soon as possible. Avoid working alone inside the lab. Make sure you are aware of the location of the safety equipment and features of the lab especially the first aid kit, fire exit, fire blanket, and fire extinguisher.Follow instructions carefully.Dispose materials properly.Report any faulty equipment as soon as possible.Avoid touching hot surfaces with bare hands. Wash all used glassware.Keep workstation clean and tidy to avoid accidents.Avoid eating and drinking inside the lab.Put away unnecessary things. Only materials needed for the investigation must be on the workstation.

Further Explanation:

In his safety contract, Chris will find statements that has him agreeing that he will behave appropriately inside the lab especially since they will be working with an open fire (Bunsen burner) or a heating equipment (hot plate) to change the temperature of the water. Proper behavior and basic expectation inside a lab are in the items listed above.

Answer from: Quest

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

Answer from: Quest

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
