Answer
Correct Answer is (B. Marie Sklodowska-Curie's)
Explanation:
I would research the family of Marie Sklodowska-Curie's because Marie Curie's Immediate Family is known for Winning Five Nobel Prizes. Not only did Marie Curie win two Nobel Prizes, but her family has been the recipient of five total Nobel Prizes. She won two, her husband, Pierre Curie, won one. Her daughter, Irène Joliot-Curie, won the Chemistry Prize in 1935 with her husband.
In 1903, Marie Curie and her husband (Pierre Curie) was awarded with the Nobel Prize for Physics, for their study into the spontaneous radiation discovered by Becquerel.
In 1911 Marie Curie received a second Nobel Prize for Chemistry, for her discoveries and studies of the elements radium and polonium. She is the only woman so far, who has been awarded the Nobel Prize twice.
In 1935, Marie Curie's daughter, Irene Joliot-Curie, was awarded with Nobel Prize in Chemistry Joliet share it with her husband, Frderic Joliot, for their synthesis of new radioactive elements.
Viron = 4/3 πr Fr^3
Valu = 4/3 πr Al^3
pFr * 4/3πrfe^3 = pAl*4/3πrAl^3
or
rAl =

Answer:
distance = 112 miles
Explanation:
its 12 miles every 0.6 in a hour
Answer:
The answer to your question is a = -1.85 m/s² the acceleration is negative because it is coming to stop.
Explanation:
Data
vo = 25 m/s
t = 13.5 s
a= ?
vf = 0 m/s
Formula
vf = vo + at
solve for a
a = (vf - vo)/t
Substitution
a = (0 - 25) / 13.5
Simplification
a = -25/13.5
Result
a = -1.85 m/s²
A )
T = mB g + mB a
T + mA a - mA g sin 35° = (Mi) mA g cos 35°
------------------------------------------------------------
T = 2.7 · 9.81 + 2.7 a
T = 26.487 + 2.7 a
26.487 + 2.7 a + 2.7 a - 2.7 · 9.81 · 0.574 = 0.15 · 2.7 · 9.81 · 0.819
5.4 a + 26.487 - 15.2023 = 3.2539
5.4 a = 8.0296
a = 1.487 ≈ 1.5 m/s²
B )
T = 2,7 · 9.81 = 26.487
26.487 - 15.2035 = (Mi) · 2.7 · 9.81 · 0.819
11.2835 = (Mi) · 21.69
(Mi) = 11.2835 : 21.69 = 0.52
