Answer:
a) 1200 kN/m²
b) 1,200,000 kg/ms²
c) 1.2 × 10⁹ kg/km.s²
Explanation:
Given:
Pressure = 1200 kPa
a) 1 Pa = 1 N/m²
thus,
1000 N = 1 kN
1200 kPa = 1200 kN/m²
b) 1 Pa = 1 N/m² = 1 kg/ms²
Thus,
1200 kPa = 1200000 Pa
or
1200000 Pa = 1200000 × 1 kg/ms²
or
= 1,200,000 kg/ms²
c) 1 km = 1000 m
or
1 m = 0.001 Km
thus,
1,200,000 kg/ms² = 
or
= 1.2 × 10⁹ kg/km.s²
<span>The elements of the periodic table are classified into three categories: inert gases, nonmetals and metals. Generally, inert gases do not readily gain nor lose electrons, while nonmetals are more likely to acquire electrons. Metals contain low ionization energies, which refer to the amount of energy required to free or remove an electron. These elements also have low electron affinities, or the attractive forces between an incoming electron and the nucleus of an atom. The lower the ionization energies and electron affinities of an atom are, the greater the tendency to lose electrons.</span>
Answer:
Explanation:
Given:
- depth of fish,
- angle of incidence,
- refractive index of water,
<u>Apparent distance from the normal projection at the bottom of entrance at air-water surface to the fish:</u>
<u>Now according to Snell's Law:</u>
<u>Now the actual distance of the fish from the bottom surface at the normal:</u>
<u>Now distance between bullet hole and fish</u>:
Answer:
17582.4 L
Explanation:
Ideal gas law:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is universal gas constant,
and T is absolute temperature.
Since n is constant:
PV / T = PV / T
(1 atm) (6000 L) / (273 K) = (0.3 atm) V / (240 K)
V = 17582.4 L
