Explanation:
Resistors connected in series obey the following equation:
Resistors connected in parallel obey the following equation:
The total current of the circuit will obey the Ohm's Law: V = IR. And the current will be divided across the resistors (bulbs) depending on their resistances. So, if a bulb has a higher resistance, then its current will be lesser, and it will be less bright. If a bulb has a lower resistance, then its current will be higher, and it will be brighter.
According to the above resistances connected in series and parallel, clearly, the resistances (bulbs) connected in series will have more resistance in total, and therefore less current will flow across them, and they will be less bright.
Answer:
This slide shows the three forces that act on a baseball in flight. The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion
Ohms law = v= Ir
V= 0.02 x 4000 = 80v
Pressure is defined as the force applied per unit area of the press. In this case, we are given with a force equivalent to 350 N and an area equal to 4 cm2. 4 cm2 is equal to 0.0004 m2. We divide 350Newton by 0.0004 square meters equal to 875,000 Pascals or 875 kiloPascals.
Answer:
First statement: The particles which are displaced is parallel to the direction of energy transport or to the direction the wave travels.
Second statement: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position.
Third statement: wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
Explanation:
Wave can be defined as a displacement that occurs in a medium, from one point to another. There are two different kinds of waves in physics which includes:
- Longitudinal wave and
- Transverse wave.
In a longitudinal wave, particles are displaced parallel to the direction of energy transport or to the direction the wave travels. There are also different properties which can be used to describe a longitudinal wave and they includes:
- amplitude: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position in a longitudinal wave.
- wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
