Explanation:
Animas and plants react to stimuli which may come from other living things or from the environment. A stimulus causes the organism which receivs it to respond to it. Therefore the stimulus changes the behavior in the organism in some way.
Answer:
1)A
2)B
3)C
4) D
5) C
Explanation:
1)
System is an isolation of matter that has been chosen out of the universe and studied.
2)
Surroundings are everything outside the system that interacts with the matter within the system externally
3)
Thermal energy is associated with constant random motion of atoms and molecules associated with Temperature.
4)
Chemical energy is the energy stored in the bonds between the atoms and molecules. Breaking and making of these bonds lead to releasing and absorbing of energy to surroundings.
5)
Kinetic Energy is the energy associated with the motion of the particles.
Following your push the ball rolls down the lane at 4.2m/s. What is the net force on the ball as it rolls down the lane at the constant speed?
Answer:
The value of each charge is 4.22 x 10⁻⁵ C
Explanation:
Given;
distance between the two identical charges, d = 2 m
the force of repulsion between these two charges, F = 4N
Apply Coulomb's law;
Therefore, the value of each charge is 4.22 x 10⁻⁵ C
