Answer:
Las presión ejercida por los tacos sobre el suelo es 900 libras por pulgada cuadrada.
Explanation:
Según la Física, comprendemos que la presión es igual a la fuerza dividida por área. En este caso, el peso de la persona dividida por área total de los tacos de los zapatos de golf suponiendo una distribución uniforme de la fuerza. Es decir:
(Eq. 1)
Donde:
- Presión, medida en libras por pulgada cuadrada.
- Peso de la persona, medida en libras.
- Cantidad de tacos en los zapatos, adimensional.
- Área del taco, medida en pulgadas cuadradas.
Si conocemos que 
, 
y 
, la presión es:
Las presión ejercida por los tacos sobre el suelo es 900 libras por pulgada cuadrada.
Answer:
a) 27.2 V
b)27.2 V
Explanation:
Charge of the electron =charge of the proton = q = 1.6 × 10⁻¹⁹ C
Radius = r = 0.53×10⁻¹⁰ m
Electric Potential = V = k q/r
k = 9 ×10⁹ N m²/C² = Coulomb's constant.
V = (9 ×10⁹)(1.6 × 10⁻¹⁹)/( 0.53×10⁻¹⁰) = 27.2 V
b) Potential Energy of the electron = k q × q / r
= [(9 ×10⁹)(1.6 × 10⁻¹⁹)(1.6 × 10⁻¹⁹) / (0.53×10⁻¹⁰)] / (1.6 × 10⁻¹⁹) eV,
since 1 electron volt = (1.6 × 10⁻¹⁹)joules
= 27.2 eV
At the instant you dropped it from your hand, its speed was zero.
The coin gained 9.8 m/s every second it fell. At the end of 1.85 sec,
just before it went 'tink' onto the ground, its speed was
(9.8 m/s) x (1.85 sec) = 18.13 m/s .
Its velocity at that final instant was 18.13 m/s downward.
