a. The restoring force in the spring has magnitude

F[spring] = k (0.79 m)

which counters the weight of the mass,

F[weight] = (0.46 kg) g = 4.508 N

so that by Newton's second law,

F[spring] - F[weight] = 0   ⇒   k = (4.508 N) / (0.79 m) ≈ 5.7 N/m

b. Using the same equation as before, we now have

F[weight] = (0.75 kg) g = 7.35 N

so that

(5.7 N/m) x - 7.35 N = 0   ⇒   x = (7.35 N) / (5.7 N/m) ≈ 1.3 m

Answer:

One way of writing frequency difference for "Lyman" series is

f = 3.289 * 10^15 (1 / 1^2 - 1 / n^2)

f = 3.289E15 * (1 - 1/9) = 2.924E15    as frequency difference of terms

E = h f = 6.63E-34 * 2.924E15 = 1.938E-18 Joules

1 eV = 1.60 * 10^-19 Joules

1.938 / .16 = 12.1 eV

When there's a hazard ahead, it's almost always quicker for you to steer away than to come to a full stop.

Hazard refers to any obstacle or other feature which causes risk or danger.

Living organisms respond to hazards via the production of adrenaline hormone. This hormone causes a flight response away from the hazard.

Therefore, when there's a hazard ahead, it's almost always quicker for you to steer away than to come to a full stop.

If the helium behaves as an ideal gas, its final volume is 0.13m³.

The ideal gas law states "that pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature of gas. It is expressed;

PV = nRT

Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant.

Given the data in the question;

To determine the volume of the helium gas, we substitute our given values into the expression above.

PV = nRT

V = nRT / P

V = ( 2mol × 8.31451 m³Pa/Kmol × 321K ) / 42556.5Pa

V = 5337.91542m³Pa / 42556.5Pa

V = 0.13m³

Therefore, if the helium behaves as an ideal gas, its final volume is 0.13m³

When a chunk of cosmic material the size of a golf ball or a baseball hits the Earth's atmosphere it makes a fireball.

Meteor shower is an event that occurs when tiny particles of stones that are of the size of a golf ball or baseball hits the earth's atmosphere.

As the particles enters the earth's atmosphere, they create friction through rubbing against the particles of the air. This eventually causes the particles to heat up leading to the formation of a fireball.

Meteor shower usually occurs between midnight and the very early hours of the morning.

Therefore, when a chunk of cosmic material the size of a golf ball or a baseball hits the Earth's atmosphere it makes a fireball.
