Then, number of protons would be equal to number of electrons.

The same number as the number of electrons in the cloud.

A solid object has a density of 2.85 g/cm3. According to Archimedes, what can be done to make this object float in water?

2: It's not just the capillary action, but the pull from transpiration (the evaporation of water from the tree) that is used to pull water up from the roots.

The second question needs context. Strong bonds alone won't cause tension. I don't see how adhesion is different. High vapour pressure could do it, but it's the difference in pressures that'd cause tension (and the resistance of that pressure by the surface). So, a low and high pressure would be needed. Poorly worded question :( 

1: "Adhesion is the tendency of certain dissimilar molecules to cling together due to attractive forces." [1] 

3: The other three answere would not work. Think of a boat. 

3: If you push gas, it will be compressed(get smaller). If you push liquid it will push something else. Thus, liquids are good for transferring force. This is a hydraulic system.

Horse does 200 lb while pulling a sled for 3 mi .how much work does the horse do?

Anestetic [448]

Let's convert the quantities in SI units first.
The force exerted by the horse is
$F=200 lb=889.6 N$
and the distance covered is
$d=3 mi=4828 m$
Therefore, the work done by the horse is equal to the product between the force applied and the distance:
$W=Fd=(889.6 N)(4828 m)=4.29 \cdot 10^6 J$

How long will it take 24 C of charge to flow in a 6.0 A circuit? O 0.25 S O 4.05 o 185

RoseWind [281]

Explanation:

charge=24

current =6.0

time=?

formula

c harge=current ×time

charge/current=time

24/6.0=time

4.05second=time

A positive charge +q1 is located to the left of a negative charge -q2. On a line passing through the two charges, there are two

AfilCa [17]

Answer:

please the answer below

Explanation:

(a) If we assume that our origin of coordinates is at the position of charge q1, we have that the potential in both points is

$V_1=k\frac{q_1}{r-1.0}-k\frac{q_2}{1.0}=0\\\\V_2=k\frac{q_1}{r+5.2}-k\frac{q_2}{5.2}=0\\\\$

k=8.89*10^9

For both cases we have

$k\frac{q_1}{r-1.0}=k\frac{q_2}{1.0}\\\\q_1(1.0)=q_2(r-1.0)\\\\r=\frac{q_1+q_2}{q_2}\\\\k\frac{q_1}{r+5.2}=k\frac{q_2}{5.2}\\\\q_1(5.2)=q_2(r+5.2)\\\\r=\frac{5.2q_1-5.2q_2}{q_2}$

(b) by replacing this values of r in the expression for V we obtain

$k\frac{q_1}{\frac{5.2(q_1-q_2)}{q_2}+5.2}=k\frac{q_2}{5.2}\\\\\frac{q_1}{q_2}=\frac{(q_1-q_2)}{q_2}-1.0=\frac{q_1-q_2-q_2}{q_2}=\frac{q_1-2q_2}{q_2}$

hope this helps!!
