b) The equation of equilibrium for the truck is:
The force of the SUV's bumper on the truck's bumper is:
Answer:
When you hit a baseball with a bat, you are applying a force only in the time while the bat is in contact with the ball, after that, the horizontal speed of the ball is constant. (if you ignore the friction of the air)
This happens because of the second Newton's law:
Force is equal to mass times the acceleration or:
F = m*a
If we do not have a force, then we do not have acceleration.
This means that the change in position for a fixed amount of time is constant, so horizontal speed is constant.
Radio waves, Television waves, Microwaves, Infrared light, Visible light, Ultraviolet rays, X - rays, Gamma rays, and i think thats about it.
Sorry if i get this wrong Im in elementry school
Hope this helped :)
Answer: A
Explanation: E=hv, E-energy, h-Planck constant, v-frequency
E=6.63×10^(-34)*535*10^3=3.55*10^(-28) (J) Photon energydoesn't depend on the power of radio station
Answer:
Two resistors in parallel can be placed in series with the third.
Two resistors in series can be placed in parallel with the third.
The resistors can all be connected in series.
The resistors can all be connected in parallel.
Explanation:
When we want to connect three resistors in a circuit, four options are open to us; these options are:
Two resistors in parallel can be placed in series with the third.
Two resistors in series can be placed in parallel with the third.
The resistors can all be connected in series.
The resistors can all be connected in parallel.
In each case we obtain an equivalent or net resistance. We cannot connect the resistors to the equivalent resistance since the equivalent resistance is obtained from the arrangement of the three resistors in each case.
