C is your answer im pretty sure
Explanation:
A positive point charge Q is fixed on a very large horizontal friction less tabletop. A second positive point charge q is released from rest near the stationary charge and is free to move.
As per the law of conservation of energy the change in kinetic energy is equal to the change in potential energy.
The mathematical expression for the conservation of energy is given by :
On solving the above equation, we get the value of v as :
In the above expression, as the term increase, as increases, the value of decreases. So, the correct option is (B) "As it moves farther and farther from Q, its speed will increase".
Answer:
Developmental psychologists
Explanation:
Developmental psychology is defined as the scientific study that why and how a person change over their entire lifespan. It explains that how the thinking, behavior and feeling of a person changes throughout their life.
Parent have great influence on their child's mindset and there are several instances where parent's thinking determine what their child become in near future. For example, during toddler-hood babies learn to walk and talk and with time development of language take place which is largely determined by the behavior, thinking and feeling of parent.
Answer:
The velocity of the wave is, v = 180,000 m/s
Explanation:
Given data,
The frequency of the wave, f = 900 Hz
The wavelength of the wave, λ = 200 m
The formula for the speed of the wave when the frequency and wavelength are known,
v = λ x f
Substituting the given values in the above equation,
v = 200 m x 900 Hz
v = 180000 m/s
Hence, the velocity of the wave is, v = 180,000 m/s
