Answer:
Work done by the gas for the given volume and pressure pounds foot
Explanation:
Given
Pressure applied pounds per square foot
Initial Volume cubic feet
Final Volume cubic feet
As we know pressure is inversely proportional to V
where k is the proportionality constant
V is the volume and
P is the pressure
Work done
Integrating the above equation, we get-
Work done by the gas for the given volume and pressure pounds foot
Based on Newton's second law:
Force = mass x acceleration
For this problem: we have the mass = 1232 kg and the acceleration = 2 m/s^2
So, just substitute with the givens in the above equation to calculate the force as follows:
Force = 1232 x 2 = 2464 Newtons
Higher wattage means that the bulb will draw more current to it.
100W is more than 75W, so the answer is 2) 100W.
Answer:
d = 0m
v_avg = 2.5 m/s
Explanation:
A) The distance traveled by the swimmer was:
However, the displacement is zero because the final position of the swimmer is the same as the initial position.
displacement = 0m
The average velocity was:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
A) La distancia recorrida por el nadador fue:
Sin embargo, el desplazamiento es cero porque la posición final del nadador es la misma que la posición inicial.
desplazamiento = 0m
La velocidad promedio fue:
