Answer:
no
Explanation:
the inertia of an object does not make it to come to rest, this is normally caused by friction
Answer:
T = 34.54 N
Explanation:
First we find the buoyant force acting on the sphere, due to displaced water. For that purpose, we need to find the volume of water displaced by the sphere.
Volume of Water Displaced = V = (Mass of Sphere)/(Density of metal)
V = 4.7 kg/(4000 kg/m³)
V = 0.001175 m³
Now, the buoyant force is given as:
F = (Density of Water)(V)(g)
F = (1000 kg/m³)(0.001175 m³)(9.8 m/s²)
F = 11.52 N
Now, we find the weight of the sphere:
W = mg = (4.7 kg)(9.8 m/s²)
W = 46.06 N
Since, both the tension force (T) and buoyant force act in upward direction, while the weight of sphere act in downward direction. Therefore,
W = T + F
T = W - F
T = 46.06 N - 11.52 N
<u>T = 34.54 N</u>
The pull of the moon on Earth's tidal bulge is causing The moon to slowly move farther away from the Earth. Hope that helps.
Answer:
v = 2917.35 m/s
Explanation:
let Fc be the centripetal force avting on the satelite , Fg is the gravitational force between mars and the satelite, m is the mass of the satelite and M is the mass of mars.
at any point in the orbit the forces acting on the satelite are balanced such that:
Fc = Fg
mv^2/r = GmM/r^2
v^2 = GM/r
v = \sqrt{GM/r}
= \sqrt{(6.6708×10^-11)(6.38×10^23)/(3.38×10^6 + 1.62×10^6)}
= 2917.35 m/s
Therefore, the orbital velocity of the satelite orbiting mars is 2917.35 m/s.
