No not all of them. some can though.
Answer:
20,000 N
Explanation:
First find the acceleration:
a = Δv / Δt
a = (0 − 40 m/s) / 10 s
a = -4 m/s²
Next use Newton's second law to find the force on the car:
F = ma
F = (5000 kg) (-4 m/s²)
F = -20,000 N
According to Newton's third law, the force on the wall is equal and opposite the force on the car.
F = 20,000 N
Answer:
The value is 
Explanation:
From the question we are told that
The voltage is 
The current is 
Generally the resistance value is mathematically represented as
=> 
=>
I believe an Atom is a very powerful source, the basic unit of a chemical element. An atom is a source of nuclear energy.
But a molecule on the other hand isn't so different.
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
I hope that helps, have a fantastic day!
