Answer:
True.
Explanation:
An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.
Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, etc.
This electrical network which is usually a closed loop comprises of a device that provides the energy (voltage) to drive electrons or electric current; the device is referred to as a source such as a generator or battery.
Similarly, an integrated circuit (IC) also referred to as microchip can be defined as a semiconductor-based electronic component that comprises of many other tiny electronic components such as capacitors, resistors, transistors, and inductors.
Generally, integrated circuits (ICs) are used in virtually all modern electronic devices to carry out specific tasks or functions such as amplification, timer, oscillation, computer memory, microprocessor, etc.
An applied force must be applied to move a load. This applied force must be large enough to overcome any opposing forces in order to move the load.
Answer:
36 km /h means 10 m/s. Increase in speed is 10m/s in 5 s . Acceleration is ( 10/5 ) = 2 m/s^ 2.
Answer:
Explanation:
In order for the car does not slip, the frictional force must be equal to the centripetal force due to the circular motion. According to the free body diagram:
The frictional force is given by:
The centripetal force is defined as:
Here v is the linear speed and r is the radius of the circular motion. Replacing this equations:
Answer:
0 m/s
Explanation:
Average velocity of an object is given by the net displacement divided by time taken. Displacement is equal to the shortest path covered by the object.
In this problem, a player runs the length of the 30-meter court and back. The player does this three times in 60 seconds.
As the player runs the court and returns to the original point. It would mean that the shortest path covered is 0.
Average velocity = displacement/time
v=0/30
v = 0 m/s
Hence, the correct option is (1).
