Answer:
High density D answers to your questions
Answer:
Range of wavelength will be 
to 
Explanation:
We have given range of frequency is 400-560 Hz
Speed of the light 
We have to find the range of the wavelength of signal transmitted
Ween know that velocity is given by 
, here 
is wavelength and f is frequency
So for 400 Hz frequency wavelength will be 
And wavelength for frequency 560 Hz 
So range of wavelength will be to
Potential energy is first transformed into kinetic energy as she pedals, then gravitational as she coasts down the hill.
Newtons second law says that the acceleration of an object (produced by a net force) is directly proportional to that magnitude of the net force. E.g. F = ma
where F is the net force of an object, m is mass and a is acceleration.
For example, if an object had a large mass, there would have to be more force in order to move it than if it was lighter.
In a linear motion, if you pushed two objects, one slightly larger than the other, with the same force, the acceleration of the smaller object would be bigger than the larger one. So the motion (change in position over time), of the larger object would be seen as lesser than the smaller one (in a situation where both forces are equal).
Answer:
4m/s
Explanation:
due to newtons second law of motion
the accelerations that result when a 12-N net force is applied to a 3-kg object. A 3-kg object experiences an acceleration of 4 m/s/s.
