Answer:
The average velocity of the entire trip is 42.5 mph east ⇒ answer C
Explanation:
The average velocity of an object is its total displacement divided by
the total time taken.
It is the rate at which an object changes its position from one
place to another.
It is a Vector quantity
A car travels 25.0 miles due east for one hour
Then it travels another 60.0 miles east for an additional hour
We need to find his average velocity of the entire trip
He is travels due east in the whole trip
The total displacement that he travels = 25 + 60 = 85 miles east
He travels the first part in 1 hour and the second part in another hour
The total time for the whole trip = 1 + 1 = 2 hours
The average velocity = total displacement ÷ total time
His average velocity = 85 ÷ 2 = 42.5 miles/hour east
<em>The average velocity of the entire trip is 42.5 mph east</em>
Without a picture of the situation, we don't know the relationship
between angle-G, g, k, and 'h'. We don't even know for sure
whether 'h' is on the same planet as the other things. No answer
is possible without seeing the picture.
When you turn on a battery-operated device, an electrical circuit is closed.
Explanation:
A circuit works, only when it is closed. When we turn on the battery-operated device, the circuit is closed & complete. Hence, the current will flow across the circuit.
Only closed circuits work (current flows through them). No current can flow in an open circuit.
