Answer: Differences: Solids have particles that are tightly packed and they form a pattern. In this case, they move and vibrate in place. On the other hand, liquid particles are close together but they have an irregular arrangement. The spaces between the particles allow them to move freely.

A pendulum is timed, first for 20 swings and then for

wlad13 [49]

$w = \frac{t(50) - t(20)}{50 - 20} = \frac{43.2 - 17.4}{50 - 20}$

$w = \frac{25.8}{30} = 0.86 \: sec \: per \: swing$

The results may differ due to resistive forces that may be affecting the system by decelerating it or any other external forces that might accelerate it a bit.Or the timing could be a little inaccurate.

The current in a light bulb is 0.835A.How long does it take for a total charge of 1.67 C to pass a point in the wire

adelina 88 [10]

Explanation:

Given parameters:

Current = 0.835A

Quantity of charge = 1.67C

Unknown:

Time taken = ?

Solution:

The quantity of electricity Q in coulombs is the product of the current I and time t.

Q = I x t

Q is the quantity of electricity in coulombs

I is the current

t is the time taken

input the values and solve for t;

1.67 = 0.835 x t

t = $\frac{1.67}{0.835}$ = 2s
