Answer:
123.2 m/s after 28s
Explanation:
Vi= 0 m/s
a= 4.4 m/s^2
t=28s
Vf after 28s
To find Vf use your kinematics formula Vf=Vi+at
Vi is Zero so it gets removed and the equation becomes
Vf=at
Simply Plug and Solve
Vf= 4.4(28)
Vf=123.2 m/s after 28s
Answer:
M = 5.882 10²³ kg
Explanation:
Let's use Newton's second law to analyze the satellite orbit around Mars.
F = m a
force is universal attraction and acceleration is centripetal
a = v²/ R
the modulus of velocity in a circular orbit is constant
v= d/T
the distance of the cicule is
d =2pi R
a = 2pi R/T
we substitute
- G m M / R² = m ( 
)
G M = 
M = 
the distance R is the distance from the center of the planet Mars to the center of the satellite Deimos
R = 23460 km = 2.3460 10⁷ m
the period of the orbit is
T = 1,263 days = 1,263 day (24 h / 1 day) (3600s / h)
T = 1.0912 10⁵ s
let's calculate
M = 
M = 509.73418 10²¹ /8.66640 10⁻¹
M = 58.817 10²² kg
M = 5.882 10²³ kg
Force is indirectly proportional to the distance. Therefore when the distance increases the force of attraction increases and the answer would be B
Since Monique is able to hear the heartbeats of her baby, it's the Fetus stage of pregnancy when the body starts developing inside the womb.
<u>Explanation:</u>
The Fetus Stage of Pregnancy:
Once the 4th-7th weeks of pregnancy passed, the embryo start developing inside the womb of the mother and the respective symptoms reflects. This is the Fetus stage of pregnancy which occur in approximately around the 10th week of pregnancy.
In the fetus stage, the human body begins to develop inside the womb. In this phase, most of the organs are developed and the limbs starts to form firmly. The Fetus stage comes after the Embryo stage but usually, the transition varies according to the growth and circumstances of the atmosphere.
But, what is certain is that the mother can feel the impulse and heartbeats of the baby inside her womb which is an exciting and memorable feeling for her.
The airtime is 9.8
the velocity is 0
