Answer:Magnitude of tension in the string is less than the weight of rock
Explanation:
Given
Rock is suspended from the string and it accelerates downward
Let T be the Tension in the string
thus
mg-T=ma
where a =acceleration of rock
T=mg-ma
T=m(g-a)
Thus Tension in the string is less than the weight of rock
Answer:
the faster it moves(if it is free) . the less the inertia (potential) and the more the inertia (kinetic)
the more (at times x2) force and momentum it comes back at you
Answer:
2.56 N*m
Explanation:
Torque is force times distance, with the force being perpendicular to the distance.
If the force and distance are not perpendicular, a projection of one of the two must be used instead.
We will use the projection of the length of the shaft upon a perpendicular of the force applied. This will have a magnitude of:
Lh = L * cos(a) (I name it Lh because it is a horizontal projection in this case)
Lh = 0.2 * cos(π/5) = 0.16 m
Then:
T = f * d
T = 16 * 0.16 = 2.56 N*m
Answer:
Blue light
Explanation:
Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves.
