Explanation:
Given parameters:
Wavelength of photon = 827nm = 827 x 10⁻⁹m
Unknown:
Energy of the photon = ?
Type of radiation = ?
Solution:
The energy of a photon can be derived using the expression below:
E = 
h is the Planck's constant = 6.63 x 10⁻³⁴m²kg/s
c is the speed of light = 3 x 10⁸m/s
Insert the parameters and solve;
E = 
E = 2.4 x 10⁻¹⁹J
Type of radiation:
Near infrared radiation
I think it’s a carrot . pretty sure
Answer:
nah but ill take points tho
Explanation:
Answer: 120N
Explanation:
Given variables are:
force needed = ?
mass of object = 60 kg
acceleration = 2.0 m/s²
Since the magnitude of force depends on the mass of the object and the acceleration by which it moves.
i.e Force = mass x acceleration
Force = 60 kg x 2.0 m/s²
Force = 120 N
Thus, 120 Newton of force is needed to make 60 kg object accelerate at a rate of 2.0 m/s²
