Answer:
<h3>The answer is 61,200 m</h3>
Explanation:
To find the distance covered by the dolphin , we use the formula
<h3>distance = velocity × time</h3>
From the question
velocity = 17 m/s
time = 3600 s
We have
distance = 17 × 3600
We have the final answer as
<h3>61,200 m</h3>
Hope this helps you
Explanation:
Convert the time to seconds : 5minutes × 60 = 300seconds
Acceleration = Velocity / Time
Acceleration = 20m/s / 300s
Acceleration = 0.067m/s²
Distance = Velocity × Time
Distance = 20m/s × 300seconds
Distance = 6000m
Answer: Spina bifida
Explanation:
Spina bifida is a developmental defect in which a portion of the spinal cord protrudes outside the vertebrae.
Spina bifida is a birth defect that occurs when there is improper formation of the spine and spinal cord. It's a type of neural tube defect. The structure in a developing embryo that eventually becomes the baby's brain, spinal cord and the tissues that enclose them is the neutral tube.
Explanation:
option D
you compare the data from your experimental results to the prediction being tested
m = mass of the person bouncing = 78 kg
k = spring constant of the bathroom scale = 1.5 x 10⁶ N/m
v = maximum velocity of the person
A = maximum compression of the spring of scale = 0.115 cm = 0.00115 m
h = height gained at maximum speed = A = 0.00115 m
Using conservation of energy
spring potential energy = kinetic energy + gravitational potential energy
(0.5) k A² = (0.5) m v² + m g h
k A² = m v² + 2 m g h
(1.5 x 10⁶) (0.00115)² = (78) v² + 2 (78) (9.8) (0.00115)
v = 0.0538 m/s
