Battery based heaters use electric resistance heating, which uses a lot of current (electricity) to create the heat.
The formula that links voltage (V), resistance (R) and current intensity (I) is
Solve this formula for I to get
Plug your values for V and R and you'll get the current.
Answer:
T = 2.83701481512 seconds
Explanation:
Hi!
The formula that you will want to use to solve this question is:
T--> period
L --> length of the pendulum
g --> acceleration due to gravity (9.8m/s^2)
since we know that the mass of the bob at the end of the pendulum does not affect the period of the pendulum, we can go ahead and ignore that bit of information (unless, of course, the weight causes the pendulum to stretch)
so now we can plug in our given info into the formula above and solve!
T = 2*pi * sqrt(2/9.8)
T = 2.83701481512 seconds
*Note*
- I used 3.14 to pi, if you need to use a different value for pi (a longer version, etc) your answer will be slightly different
I hope this helped!
Answer:
A) El desplazamiento total del viaje es 14160 centímetros.
B) La velocidad media del viaje completo es 885 centímetros por segundo.
Explanation:
A) El desplazamiento es el producto de la velocidad media por el tiempo. El desplazamiento total es la suma de desplazamientos asociados a cada velocidad media, entonces:
El desplazamiento total del viaje es 14160 centímetros.
B) La velocidad media del viaje es el desplazamiento total dividido por el tiempo total, es decir:
La velocidad media del viaje completo es 885 centímetros por segundo.
