How do I calculate how many meters are in 7.2 light years?

Physics
1 answer:
Vikentia [17]3 years ago
5 0

Answer:

68.2 Quadrillion meters

Explanation:

A lightyear is the distance that light travels in one year.

Speed of light is 3*10^8\ m/s

So light covers 300,000,000 meters in one second.

One year has 31536000 seconds so , light covers

9.461*10^{15}\  meters\ in\ one\ year

so 7.2 light years is

7.2*(9.461*10^{15})\\6.82*10^{16}

so 7.2 light years is

6.82 x 10^(16) meters or

68.2 Quadrillion meters

A frying pan is quickly heated on a stovetop to 200 C. It has an iron handle that is 20 cm long . Estimate how much time should
myrzilka [38]

Explanation:

Heat = mc(change in temp.)

m=mass , c = specific heat

Rate of flow of heat = heat current = kA/L(T2-T1)

So, mass = density×volume

So, mc(T2-T1)/time =

kA/L(T2-T1)

Substitute the values given as there are a lot of values missing, so the answer can not be obtained.

A book has a mass of 50 grams and an
vladimir2022 [97]

Force on the book is 0.25 N

Explanation:

  • Force is calculated by the equation, F = Mass × Acceleration
  • This is based on Newton's second law of motion, which states that the force on an object is its mass times the acceleration of the object.

Here, mass of the book = 50 g = 50/1000 = 0.05 kg (∵ 1 kg = 1000 g)

Acceleration of the book = 5 m/s²

⇒ Force = 0.05 × 5 = 0.25 N
