Increasing the pitch makes a note higher
B- the biosphere needs the hydrosphere (water) to survive. They drink the water.
C- the biosphere use the géosphère as land/ home.
D-The géosphère depends on the hydrosphere for water. Without the water, the géosphère would eventually turn dry and nothing will be able to grow
E- The animals in the hydrosphere need air to survive. The gills on sea animals are used to filter out the water from the oxygen and use the oxygen to breathe. As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that's dissolved in the water.
1. As you push a cereal box across a tabletop, the sliding friction acting on the cereal box_____.
<span> d.) acts in the direction opposite of motion. </span>
2.) Projectile motion is caused by____________.
d.) the downward force of gravity and an initial forward velocity.
Answer:
True
Explanation:
when the object is larger , the inertia of the object is larger so its tendency to change its state of motion is reduced is reduced.
Answer:
K = m g (h₀ - h_plat)
Explanation:
Let's use energy conservation to solve this problem, write the energy at two points of interest
Initial. Higher
E_initial = m g h₀
Final. Lower
E_end = K + Ep
E_end = ½ m v² + m g h_plat
Energy is conserved
E_initial = E_end
m g h₀ = K + m g h_plat
K = m g (h₀ - h_plat)
