Human lack chlorophyll, which is the function that collects energy from the Sun to conduct photosynthesis.
Answer:
Explanation:
The train travels 5 miles in the east and then 2 miles in the west . Total path length is equal to 5 + 2 = 7 miles . But the displacement is (5 - 2 ) = 3 miles . So displacement ≠ path length
The jogger is running around a circular path . In moving one round on a circular path , path length is equal to the circumference of the circle but the displacement is zero because the starting point and finish point is same.
For the ball rolling down an inclined plane , path length is length of inclined path traveled and displacement is also the same . so in this case path length equals displacement.
For a ball thrown upwards and going downwards , total path length is equal to the total of path gone up and down or twice the height but the displacement is nil if the ball comes back again in the hand.
El sol es una bola de gas así como las estrellas:)
Answer:
sphere moves with a constant terminal velocity.
Explanation:
mass of sphere, m = 0.5 kg
velocity downward, v = 8 m/s
buoyant force = 4 N
fluid friction force = 4 N
Weight of the sphere is acting downward.
W = mg = 0.5 x 10 = 5 N
When the object is immersed in a fluid and it moves in the fluid with constant velocity, it means the net force acting on the object is zero, and the object attains a terminal velocity.
Answer:
The sides move away because the rod itslef is magnitized so north and north , south and south don´t attract vice versa.
