To start the control would be import to see how drivers would act with full focus on the road. The subjects should (in order for the only difference to be the phone) is to use the same vehicle same road same weather condition, just obviously one has the phone the other does not. I hope this helps
The equation of the energy of a photon is E=h*f.
If we increase the Planck's constant h, the energy would increase.
For example, lets double the value of Planck's constant and name it H:
H=2*h. Now lets put that into the equation for energy that we will call E₂:
E₂=H*f=2*h*f=2*E.
So we can clearly see that E₂=2*E or that if we double Planck's constant, the energy also doubles.
Answer:Both
Explanation:
There are three ways to increase the induced voltage in electromagnetic induction:
1) increase the speed at which the conductor moves through the magnetic field. This means that the lines of flux are cut more quickly and more emf is induced.
2) use stronger magnets which provides a stronger magnetic field and more densely packed lines of flux.
3) use a coil of multiple loops.
Hence both technicians were correct.
Explanation:
According to Newton's second law of motion, the rate of change of momentum is directly proportional to the applied unbalanced force. The mathematical expression is given by:
Where
F is the applied force
m is the mass of the object
v is the velocity with which it is moving
Momentum of a particle is given by the product of mass and velocity as :
Hence, this is the required solution.
Answer:
d)
Explanation:
Electrons are lost or gained when the ballon is rubbed with a PVC. As the rubber ballon lost electrons, it will have more protons, hence the positive charge. (More protons than electrons in the ballon).
