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>
Answer:
Atoms cannot be divided using chemicals. They do consist of parts, which include protons, neutrons,...
Each electron has a negative electrical charge.
Each proton has a positive electrical charge.
Each neutron is electrically neutral. In other words, neutrons do not have a charge
Explanation:
Two things that aren't involved in speed: -- the straight-line distance between the start- and end- points. -- the direction from start-point to end-point.
