What is the acceleration of a 50kg object pushed with a force of 500 Newton’s
olasank [31]

Answer:

<h2>10 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m} \\

f is the force

m is the mass

From the question we have

a =  \frac{500}{50}  =  \frac{50}{5}  = 10 \\

We have the final answer as

<h3>10 m/s²</h3>

Hope this helps you

The equation for photon energy, E, is E=hcλ where h = 6.626×10−34 J⋅s (Planck's constant) and c = 2.99×108 m/s (the speed of lig
masya89 [10]

Answer:

9.133×10^-6 m

Explanation:

A photon is the smallest discrete amount or quantum of electromagnetic radiation. It is the basic unit of all light. Photons are always in motion and, in a vacuum, travel at a constant speed to all observers of 3 x 10^8 m/s.

From the question, the following details were supplied;

Energy of the photon (E) = 4.61×10^−19 J

Speed of light (c) = 2.99×10^8 m/s

Plank's constant (h) = 6.626×10^−34 J⋅s

Wavelength of the photon (λ)= ??? The unknown

From

E=hc/λ

λ= hc/E

Substituting values

λ= 6.626×10^−34 × 2.99×10^8/ 4.61×10^−19

λ= 91.33×10^-7 m

λ= 9.133×10^-6 m
