Answer:
9.38J
Explanation:
mass = 0.425kg
height (h) = 2.25m
g = 9.81m/s^2
Gravitational potential energy (PE) = mgh
Plug in all info you got:
(0.425kg)(9.81m/s^2)(2.25m) = 9.38J
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
Answer:
double
Explanation:
According to the newton's second law
force = mass x acceleration
So, acceleration is directly proportional to the force.
As the force is doubles, the acceleration is also doubled.
Answer:
6
Explanation
Any numbers in scientific notation are considered significant. For example, 4.300 x 10-4 has 4 significant figures.
