P = VI
Power = Voltage x Current
Isolate for current
P/V = I
16/7 = I
I = 2.28 A
Answer:
F = 2.3 x 10⁻⁸ N
Explanation:
Given,
The mean distance between the electron and the nucleus, x = 1 x 10⁻¹⁰ m
The number of protons present in the nucleus of the hydrogen atom is 1.
The charge of the proton and electron, q = 1.602 x 10⁻¹⁹ C
Since they have opposite charges, the force between them is attractive,
The coulomb law of force between two charges is given by the formula,
<em> </em>
= 9 x 10⁹ Nm²C⁻²
Substituting the values in the above equation
F = 9 x 10⁹ X (1.602 x 10⁻¹⁹)² / (1 x 10⁻¹⁰)²
= 2.31 x 10⁻⁸ N
Hence, the force between the nucleus and electron of hydrogen atom is, F = 2.3 x 10⁻⁸ N
Marine debris is any trash or litter that ends up in a marine environment. This harms wildlife through entanglement, ingestion, and disturbs the habitat of many species of animals. This becomes a global problem when it is a danger to human health. Nails, syringes, and glass can cause harm to people on the beach. On top of that, trash in the waterway increases the amount of chemicals destroying our water quality.

<h2>
25.32 N net force would give the same object an acceleration of 3.9 m/s²</h2>
Explanation:
We have
Force = Mass x Acceleration
A net force of 37 N gives an object an acceleration of 5.7 m/s²
F = ma
37 = m x 5.7
m = 6.49 kg
Now we need to find what net force would give the same object an acceleration of 3.9 m/s²
Force = Mass x Acceleration
Force = 6.49 x 3.9
Force = 25.32 N
25.32 N net force would give the same object an acceleration of 3.9 m/s²
