I think the correct answer would be the last option. On a cloudless day, most of the visible light that is headed towards the Earth would reach the surface wherein some is being reflected and some is being absorbed. During this time, there are no hindrances for the light so it directly reaches the surface of the Earth and is absorbed or reflected by the objects it hits.
Answer:
a) True. There is dependence on the radius and moment of inertia, no data is given to calculate the moment of inertia
c) True. Information is missing to perform the calculation
Explanation:
Let's consider solving this exercise before seeing the final statements.
We use Newton's second law Rotational
τ = I α
T r = I α
T gR = I α
Alf = T R / I (1)
T = α I / R
Now let's use Newton's second law in the mass that descends
W- T = m a
a = (m g -T) / m
The two accelerations need related
a = R α
α = a / R
a = (m g - α I / R) / m
R α = g - α I /m R
α (R + I / mR) = g
α = g / R (1 + I / mR²)
We can see that the angular acceleration depends on the radius and the moments of inertia of the steering wheels, the mass is constant
Let's review the claims
a) True. There is dependence on the radius and moment of inertia, no data is given to calculate the moment of inertia
b) False. Missing data for calculation
c) True. Information is missing to perform the calculation
d) False. There is a dependency if the radius and moment of inertia increases angular acceleration decreases
Explanation:
for their survival and defense
Explanation:
The gravitational force between two masses having masses. Let m is the mass of smaller object and M is the mass of larger object. The gravitational force between these two spheres is given by :
r is the separation between two spheres
G is universal gravitational constant,
The value of G remains same always no matter how objects are placed.
