Moth X is more likely to be eaten by insect killing birds first. This is because Moth Y blends in with the tree trunk more and is hidden from birds. Its wings camouflage with the tree trunk, hiding it from sight.

Answer:
260 km
65 km/hr
Explanation:
The displacement of an object is the distance moved by that object in a particular direction.
velocity = displacement / time, therefore,
Displacement = velocity * time.
Total displacement for the 4 HR trip = displacement for 2.5 hr + displacement for 1.5 hr
total displacement = (80 * 2.5) + (40 * 1.5)
Total displacement = 200 + 60
Total displacement = 260 Km
average velocity for the total trip = total displacement / total time taken
average velocity = 260 km/ 4 hr
average velocity = 65 km/hr
according to PBS learning media on a roller coaster energy changes from potential to kinetic energy and back again many times over the course of a ride kinetic energy is energy that an object has as a result of its motion.
roller coaster system is greatest at the bottom of the largest downhill slope on the track typically at the bottom of the lift Hill
so at the bottom
Answer:
1800 seconds
Explanation:
Given,
Distance ( d ) = 18 km
Velocity ( v ) = 10 m/s
To find : Time ( t ) = ?
Distance in km need to be converted to m.
1 km = 1000 m
18 km
= 18 x 1000
= 18000 m
So,
d = 18000 m
Formula : -
v = d / t
t = d / v
= 18000 / 10
t = 1800 seconds.
Therefore,
1800 seconds long, it will take to cover a distance of 18 km.
