Answer:
Approximately 
.
Explanation:
It is given that 
and 
are connected in a circuit in parallel.
Assume that this circuit is powered with a direct current power supply of voltage 
.
Since 
and 
are connected in parallel, the voltage across the two resistors would both be . Thus, the current going through the two resistors would be 
and 
, respectively.
Also because the two resistors are connected in parallel, the total current in this circuit would be the sum of the current in each resistor: 
.
In other words, if the voltage across this circuit is , the total current in this circuit would be . The (equivalent) resistance 
of this circuit would be:
.
Given that and :
.
Answer:
no se porque xD jajjakajajjajajajjaj
Displacement depends upon the path taken as it is a vector.
From your problem above we would have a total displacement of;
Defining +x direction as east and -x direction as west
6east-3west+1east+6east-7west
6-3+1+6-7=3 blocks east or + x-direction
So even though they walked a total of 17 blocks it ends up only being 3 blocks total in +xdirection that was travelled by displacement.
Any questions please ask.
Answer:
Constant speed: yes
Constant velocity: no
Explanation:
Let's remind the definition of speed and velocity:
- Speed is a scalar quantity, which is equal to the ratio between the distance covered (regardless of the direction) and the time taken:
- Velocity is a vector quantity, so it has both a magnitude and a direction. The magnitude is equal to the rate between the displacement of the object and the time taken, while the direction is the same as the displacement.
In this problem, we notice that:
- The speed of the car remains constant, as it is 90 km/h
- However, its direction of motion changes while the car travels round the corner: this means that the direction of the velocity is also changing, therefore velocity is not constant.
Answer:
common types of topologies, and we're going to break each of them down in the guide below.
Bus topology. As the simplest design, a bus topology requires nodes to be in a linear order. ...
Ring topology. Another simple design is the ring topology. ...
Star topology. ...
