The wavelength of the light is 6.00 × 10^(-5) m.
The formula connecting frequency <em>f</em> and wavelength λ is
<em>f</em>λ = <em>c</em>
where <em>c</em> = the speed of light [2.998 × 10^8 m·s^(-1)]
We can rearrange the formula to get
λ = <em>c</em>/<em>f
</em>
∴ λ = 2.998 × 10^10 m·s^(-1)/5.00 × 10^12 s^(-1) = 6.00 × 10^(-5) m = 60.0 µm
Try c I think is the most accurate one
Taking into account the Newton's second law, the correct answer is option A. F = 9.68 N right
In first place, acceleration in a body occurs when a force acts on a body.
Newton's second law states that a force will change the speed of an object because the speed and/or direction will change. These changes in velocity are called acceleration.
So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object
Mathematically, Newton's second law is expressed as:
F= m×a
where:
- F = Force [N]
- m = Mass [kg]
- a = Acceleration [m/s²]
In this case, you know:
- F= ?
- m= 2.2 kg
- a= 4.4 m/s²
Replacing in Newton's second law:
F= 2.2 kg× 4.4 m/s²
Solving:
<u><em>F= 9.68 N</em></u>
Finally, As the bowl of fruit accelerates to the right, the correct answer is option A. F = 9.68 N right

The ground water refers to water present in the under earth in the cracks or pores or similar spaces.We majorly depends upon this sources of water specially in rural area.
It helps in irrigation and also serve as drinking water supply.
The words or phrases which identify layer of ground water are:
a) water table: the uppermost water saturated layer
b) kettle lake: it is an underground lake (not ground water)
c) Saturation zone : this is the zone of water below the water table
d) undergound lake: this is kettle lake (not ground water)
e) sink hole: Not a layer of ground water
So the layers of ground water are
a) water table
b) saturation zone
Explanation:
P₄+O₂=P₂O₃; non-balanced
P₄+O₂=2P₂O₃; to add '2' on the right side; non-balanced
P₄+3O₂=2P₂O₃. to add '3' before O₂ in the left side; balanced
