Answer:
a) System aceleration:
b) Direction of movement:
The block 
down the plane when the acceleration is negative. This occur when:
The block 
up the plane when the acceleration is positive. This occur when:
Explanation:
For the block the move direction is parallel (||) to the plane
(1)
For the block the move direction is vertical (y)
(2)
Both blocks are connected with the same cable, therefore, the tension on the cable and the acceleration is the same for both.
Solving the equation 2 for T:
(3)
replacing (3) in the equation (1)
(4)
solving (4) for a:
Answer:
Answer 11
Explanation:
. Newton's law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them
B.
because hes doing multiple things in 1 job
The speed of light in glass is slower than the speed of light through space.
F- force on the object,
m - mass of the object:
F = 12 N = 12 kgm/s², m = 2 kg
F = m · a
a = F : m = 12 N : 2 kg = 6 m/s²
Answer: C)
