The objects that look black are all tied for first place.
The color can be determined by either the frequency or the amplitude. The amplitude is the maximum height of the wave, while frequency is the number of cycle (amplitude to amplitude) per second. <em>Thus, the answer would be: the amplitude of the wave.</em>
1. To solve this problem you can use the formula:
Force = mass × acceleration
16 = 5 × a
16/5 = a
3.2 m/sec^2 = acceleration
2. To solve this formula use the same formula that was given above:
F = ma
F= 1239 kg × 4m/sec
F = 4956 N
3. To solve this problem use the formula:
Weight = mass × gravity
W = 35 × 9.8
W = 343 N
4. To solve this problem use the formula:
Momentum = mass × velocity
M = 95 kg × 8 m/s
M = 760 kg × m/sec
hope this helps :)
Answer:
300K, 600K
Explanation:
ΔS =nCp ㏑()
= (2.5) (78.314) ㏑() = 14.41
Qp =(2.5) (8.314) (T2-T1)
= 6236 J.
=> 20.8 (T2-T1) - 6236
=> T2-T1 = 300
=> T2=T1 + 300
20.8 ㏑() =
=>
=> T1 = 300K
=> T2 = 600K
Answer:
A and B are correct both are correct
