While working on her science fair project Venus connected a battery to a circuit that contained a light bulb. Venus decided to c

hange the light bulb to a higher resistance, but she wanted to keep the current the same. What will Venus need to do?

Answer:

<em>Venus will need to use more voltage to have the same current</em>

Explanation:

<u>Ohm's Law</u>

It states that the current through a conductor is directly proportional to the voltage applied to it and inversely proportional to the resistance of the conductor. This relationship can be written as

\displaystyle I=\frac{V}{R}

Solving for V

V=IR

Venus originally connected a resistance R_1 to a voltage V_1 to get some current I

\displaystyle I=\frac{V_1}{R_1}

The voltage needed to get that current is

V_1=IR_1

If Venus changes the light bulb to another with higher resistance, say, R_2, then the current would change, unless she uses another voltage

V_2=IR_2

Since\ R_2>R_1,\ then\ V_2>V_1

Venus will need to use more voltage to have the same current

1. A diver dives off of a raft - what happens to the diver? The raft? How does this relate to Newton's Third Law?  Action Force:
Natali [406]
The Action Force of this scenario is the pushing force of the Diver. The Reaction Force is the raft pushing back on the diver. 

The Third Law of Motion states that "For every action, there is an equal and opposite reaction." Now when the diver dives off the raft, the raft is also pushing the same amount of force as the diver did as he dives off. The diver will then move forward and the raft on the other hand will move backwards.

The movement of the raft shows the opposite force. It will move backwards depending on how strong the diver will push off on the raft. And the amount of force he pushes on it, the raft will exert the same force so the stronger the force of the diver, the farther he will go because the raft will push him in that same direction as it goes backwards.

Why are bathroom tiles usually rough
Aleks04 [339]
-- Bathroom tiles are usually cool, so water condenses on them
when you take a hot bath or shower in the room. 

-- The natural result is that a smooth tile would become slippery,
exactly when you're walking around with wet feet and nothing on them ...
a dangerous situation.

-- In order to circumvent this safety hazard, the tiles in the bathroom
should be rough, especially on the floor.

Why is earth the only planet on which water exists in a liquid state
Gennadij [26K]
This is due to earths location in the solar system. Earth is in the habitat zone or the Goldie locks zone, in this zone it's not too hot or not too cold for water to exist. Other planets in different star systems have liquid oceans due to them being in the habitat zone.
