4 newtons, 4 amps, 4 joules, 4 watts, 4 ohms, 4 volts what does I=
1 answer:
Answer:
I amperes
Explanation:
Newton is the unit of force. Hence 4 newton is not the current “I”
Joules is the unit of energy and hence it do not signify current I
Watt is the unit of power i.e the rate of transfer of energy.
Ohm is the unit of resistance produces thereby obstructing the flow of current
And Volts is the unit of voltage or potential difference between two ends of an electric circuit. Thus, it is also does not signifies current.
Thus, I amperes

Answer:
-26 m/s.
Explanation:
Hello,
In this case, since the vertical initial velocity is 26 m/s and the vertical final velocity is 0 m/s at P, we compute the time to reach P:
With which we compute the maximum height:
Therefore, the final velocity until the floor, assuming P as the starting point (Voy=0m/s), turns out:
Which is clearly negative since it the projectile is moving downwards the starting point.
