Answer:
The output power of the circuit is 3 Watts.
Given:
a loss in decibels = 3 dB
Input power = 6 Watts
To find:
What is the output power?
Formula used:
Output power = Input power × loss in ratio
Solution:
3 dB loss corresponds to a ratio of 0.5
Output power can be calculated as follows:
Output power = Input power × loss in ratio
Output power = 6 × 0.5
Output power = 3 Watts
Therefore, the output power of the circuit is 3 Watts.
The answer is
-Small f and large D.
The explanation:
-A car jack acts as a machine, defined as an apparatus that aids individuals in exerting force more easily.
-Hence, by applying a small force to the jack, the height at which the car is elevated increases.
Machines are essential for people to amplify their strength; without them, lifting a car would be impossible.
Employing leverage or hydraulic principles, machines enhance your exerted force.
Utilizing a greater lever allows for extensive movement with minimal force, resulting in the opposite side moving shorter distances with an increased force.
A. A car moving at a constant speed on a flat, straight road. B. A vehicle traveling at a steady speed on a 10-degree incline. An object operates within an inertial reference frame if there is no net force acting upon it. According to Newton's second law, this implies that the object's acceleration also equals zero. Assessing the scenarios yields: A. A car moving at a constant speed on a flat road qualifies as an inertial reference frame, since its velocity and direction remain unchanged; thus, acceleration is zero. B. A car moving steadily up a 10-degree incline still constitutes an inertial reference frame, for similar reasons. C. A car accelerating after departing a stop sign does not represent an inertial frame due to its change in speed. D. A car driving at a steady speed around a curve cannot be considered an inertial reference frame since its direction is changing, resulting in a change in velocity and thus acceleration. Therefore, options A and B are correct.
Hello! Thanks for sharing your query here.
To determine the change in potential energy, you would utilize the formula:
delta PE = mg*delta h
delta PE = 0.5*9.81*(2-1.8)
delta PE = 0.98 J
The kinetic energy is derived from the potential energy.
