Answer:
m/s²
m/s²
Explanation:
Normal or centripetal acceleration measures change in speed direction over time. Its expression is given by:
Formula 1
Where:
: Is the normal or centripetal acceleration of the body ( m/s²)
v: It is the magnitude of the tangential velocity of the body at the given point
.(m/s)
r: It is the radius of curvature. (m)
Newton's second law:
∑F = m*a Formula ( 2)
∑F : algebraic sum of the forces in Newton (N)
m : mass in kilograms (kg)
Data
r= 120 m
Problem development
We replace data in formula (1) to calculate centripetal acceleration:
m/s²
m/s²
We replace data in formula (2) to calculate centripetal force Fc) :
<span>Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction which the wave moves</span>
Answer:
C. Sturdy stems
Explanation:
Sturdy stems is the adaptation that enables water hyacinth to get nutrients directly from the water because there is no roots are present for the absorption of nutrients from water. The hollow bulbous stem below each leaf of water hyacinth allows the plant to get nutrients from the water. This hollow bulbous stem allow the plants to float on the water surface, keeping the leaves and flowers above the water so they don't rot.
