Their all going to the same place your motion is moving
Correct answer: a) True.
In fact, the soil at the poles consists mainly of snow. Snow has an albedo of 90%: albedo is the fraction of light (and so, of energy) that is reflected back to the space. This means that at the poles, about 90% of the light is reflected back to the space, while only 10% is absorbed.
Answer:
Part a)
Center of mass with respect to the left end is given as

Part b)
Center of mass with respect to middle bead is

Part c)
Center of mass with respect to middle bead is

Explanation:
Part a)
As we know that the center of mass of the system of mass is given by the formula

here we have






Now we have


Part b)
As we know that the center of mass of the system of mass is given by the formula

here we have







Part c)
Now plug in the values in above formula



As you may know some objects float others do not, this is because some objects contain air or oxygen. for example an orange with a peel floats because the peal contains oxygen and an orange without a peel sinks because it does not contain air at oxygen
Answer:4.8 m/s^2
Explanation:
mass=10.5kg
Force=50.5N
Acceleration =force ➗ mass
Acceleration =50.5 ➗ 10.5
Acceleration =4.8 m/s^2
