It holds A. Less water than when it is warmer.
Answer:
The two forces acting on rockets at the moment of launch are the thrust upwards and the weight downwards. Weight is the force due to gravity and is calculated (at the Earth’s surface) by multiplying the mass (kilograms) by 9.8.The resultant force on each rocket is calculated using the equation resultant force = thrust – weight.
Hopefully, this answer helps you! :)
Answer:
Given, Apparent weight(W₂)=4.2N
Weight of liquid displaced (u)=2.5N
Let weight of body in air = W₁
Solution,
U=W₁-W₂
W₁=4.2=2.5=6.7N
∴Weight of body in air is 6.7N
Answer:Habituation is a simple learned behavior in which an animal gradually stops responding to a repeated stimulus.
Imprinting is a specialized form of learning that occurs during a brief period in young animals—e.g., ducks imprinting on their mother.
In classical conditioning, a new stimulus is associated with a pre-existing response through repeated pairing of new and previously known stimuli.
In operant conditioning, an animal learns to perform a behavior more or less frequently through a reward or punishment that follows the behavior.
Some animals, especially primates, are capable of more complex forms of learning, such as problem-solving and the construction of mental maps.
Introduction
If you own a dog—or have a friend who owns a dog—you probably know that dogs can be trained to do things like sit, beg, roll over, and play dead. These are examples of learned behaviors, and dogs can be capable of significant learning. By some estimates, a very clever dog has cognitive abilities on par with a two-and-a-half-year-old human!
