Answer:
The shape of a bird's beak is a clue to its main source of food. The shape of a bird's beak is designed for eating particular types of food such as: seeds, fruit, insects, nectar, fish, or small mammals. Bird beaks have adapted over time to help birds find food within their habitat which allows them to survive. The beak, bill, and/or rostrum is an external anatomical structure found mostly in birds, but also in non-avian dinosaurs and some mammals. A beak is used for eating and for preening, manipulating objects, killing prey, fighting, probing for food, courtship and feeding young.
Well, for one thing, it could depend on which fruit is dropped first. You haven't mentioned that.
If they're both dropped at exactly the same time, then the melon at 32m hits the ground first.
It has nothing to do with their masses or weights. It's only a matter of which one has farther to fall. Even if it were a school-bus at 96m instead of a pomegranate, anything dropped from less than 96m would reach the ground in less time than the school-bus.
Missing question: "how much work is done by the teacher?" (found on internet)
Solution:
The work done to move the desk across the floor is equal to
where F is the horizontal force applied to move the desk, and d is the distance covered by the desk. If we use F=20 N and d=5 m, we find the work done:
Answer:
Both technicians are correct.
Explanation:
Printed circuits boards are copper layers attached to a dielectric plane with some design on it. This design is made to direction the current flow through a predefined path or electrical circuit. This way is easier to interconnect electronic devices instead of using cables for each connection.
Since the printed circuit board PCB its made of cooper, touching the printed circuit board may cause in the middle term corrosion and even rust, because the cooper in touch with the salt, sweat, and other stuff from the fingerprints can react in the metal surface, creating corrosion.
Answer:
Chemical energy
Explanation:
Batteries are chemical energy because its a bunch of little reactions causing the batteries to work
