Answer:
electronic communications may be disrupted
Explanation:
Solar Flares: They occur when the magnetic field lines carrying charged particle entangle and reorganize over the photosphere of the Sun. In these flares charged particles leave the surface of the Sun to travel outwards.
If these flares are directed towards Earth, they will interact with anything related to electricity and magnetism. Out of the given options third option is correct as the electronic communication will be disrupted. If the flares are strong a complete power blackout may occur and that would disrupt all the communication channel and power transmission. Such events have occurred in the past as well.
Each time they collide with the walls they exert a force on them. More collisions mean more force, so the pressure will increase. When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume.

Answer:
Speed = 72.76mph
Explanation:
east direction signifies +
Therefore,
1515E -1125(45) = -2640
F = -2640×0.75 = -1980lbs
so,
-1980lbs = Ma
but m = 2640×g where g = 32.2 ft/s²
so,
a = -(1980/2640g) = -0.75×g = -24.15ft/s² = dv/dt
0 = V-24.15t
V =24.15t
22.5 = Vt -12.07t²
22.5 = 24.15t² - 12.07t² = 12.07t²
t = 1.37 seconds
Therefore,
V = 24.15 × 1.37 seconds = 33.1 ft/s
converting to mph gives
33.1 ft/s = 22.6 mph
now back to momentum
1515 E -1125(45) = 2640 V
1515 E = 50625+59664
Speed = 72.76 mph
