Explanation:
1. Distance, d = 5 m
Time, t = 10 s
Speed = distance/time
2. Mass, m = 10 kg
Acceleration, a = 3 m/s³
Force, F = mass (m) × acceleration (a)
F = 10 × 3
= 20 N
3. Mass, m = 7 kg
Height, h = 4 m
Potential energy, E = mgh
E = 7 × 9.8 × 4
E = 274.4 J
Hence, this is the required solution.
Answer:
Thats the third law______
An independent variable :)) hope I helped
Answer:
Higher current is normally achieved by faster moving electrons.
Explanation:
- Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.
- Current is the net charge flowing per unit time.
- Current can be represented by:
I=v×e×N×A
where,
I= current
e= electric charge
v= speed of electrons
N=no. of free electric charges per volume
- The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.
Answer:modeled as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field.
