Studdy Solution

STEP 1

Assumptions1. The type of forces between two celestial bodies like the sun and earth is gravitational. . Two people pulling on a rope in a tug-of-war each with a500 N force results in a net force of0 N, as the forces cancel each other out.
3. The law of inertia explains why it's easier to push a cart with a5 kg sack of rice than a cart with a10 kg sack of rice.
4. According to the second law of motion, the net force is the product of mass and acceleration. The object with the greatest acceleration is the one with the highest net force to mass ratio.
5. If a green ball is higher from the ground than a yellow ball and both have the same mass, the green ball has more potential energy.
6. The condition that does not exhibit kinetic energy is water inside a glass.
7. The speed of sound increases as the temperature increases.
8. The arrangement of visible light colors that shows decreasing wavelength is violet, indigo, blue, green, orange, yellow, red.
9. A substance releases heat without changing its temperature whenever it is melting and boiling.
10. The SI unit of voltage is volt.
11. The SI unit of current is ampere.
12. The voltage across a6 Ω load when3 A of current passes through it can be calculated using Ohm's law.

STEP 2

To calculate the voltage across a6 Ω load when A of current passes through it, we use Ohm's law, which states that voltage is equal to current times resistance.
V=I×RV = I \times R

STEP 3

Now, plug in the given values for the current and resistance to calculate the voltage.
V=3A×6ΩV =3A \times6\Omega

STEP 4

Calculate the voltage.
V=3A×6Ω=18VV =3A \times6\Omega =18VThe voltage across the6 Ω load is18 volts.
