Answer:
a. Volts = current x resistance
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Hence, Ohm's law gives the relationship between voltage, current and resistance of an electric circuit.
The answer is C.
An object on the moon is six times lighter than on Earth.
Answer:
The speed of the ball is 42.5 m/s
Explanation:
The initial kinetic energy of the ball is:
= 85.75 J
The speed of the ball after leaving the bat is:
V=47.92 m/s
Using kinematic equation we can find the speed of the ball after being 25 m above the point of collision:
The speed of a mechanical wave depends on the mechanical properties
of the medium through which the wave is traveling.
The speed of an electromagnetic wave depends on the electrical properties
of the medium through which the wave is traveling.
It's pretty well unanimous for choice <em>A</em> .
Answer:
medium
Explanation:
A substance or particle that wave travel through is called medium. There are two main types of such medium, some contains particles and some are vacuums.
- Waves can travel through a vacuum which contains no particles.
- Some can also contain particles.
- Waves can interact in different ways with the medium.
