Water atoms move more easily than ice
Ice is in a fixed crystal structure, it obviously has a lower temperature than liquid water, the state does not determine the charge, and when water freezes the crystalline structure actually makes it less dense than liquid because atoms are evenly spaced apart.
Answer:
1.41s
5.95m/s
0.2746m
Explanation:
The time period
T = 1/f
= 1/0.709s
= 1.41 seconds
We have
T = 2π√l/g
T² = 4π²l/g
g = 4π²l/T²
g = 4x3.14²x0.300/1.41²
g = 5.95m/s² this is the acceleration due to gravity.
Then the time period of the glide
T2 = 2π√m/k
Length of pendulum = l
Time period T
T2 = 2π√l/g
Then T1 = T2
2π√m/k = 2π√l/g
M/k = l/g
L = g.m/k
L = 5.95x0.450/9.75
L = 0.2746
This must be the length of the simple pendulum
PM me the statements, and i'll answer it then.
Answer:
3b+2
Explanation:
First your question has so many mistakes
What I understand
bracelets cost 4+5b
necklaces cost 8b+6
First we have to make an equaion
=(8b+6)-(4+5b)
simplify it
=8b+6-4-5b
=3b+2 Answer
