Answer:
The acceleration expressed in the new units is 
Explanation:
To convert from 
to 
it is necessary to remember that there are 1000 meters in 1 kilometer and 3600 seconds in 1 hour:
Then by means of a rule of three it is get:
Hence, the units of meters and seconds will cancel. Notice the importance of square the ratio 3600s/1h, so that way they can match with the other units:
So the acceleration expressed in the new units is .
Answer:
The answer to your question is given below.
Explanation:
From the diagram given in the question, we can see that the bulbs are in parallel connection. This implies that different current will go through the bulb but the same voltage. But the resistance of each bulb is the same, therefore the same current current will go through them.
This can further be understood if we determine the current flowing through each bulb. This is illustrated below:
Voltage (V) = 30V
Resistant 1 (R1) = 15Ω
Current 1 (I1) =..?
V = I1R1
30 = I1 x 15
Divide both side by 15
I1 = 30/15
I1 = 2A.
Voltage (V) = 30V
Resistant 2 (R2) = 15Ω
Current 2 (I2) =..?
V = I2R2
30 = I2 x 15
Divide both side by 15
I2 = 30/15
I2 = 2A.
The overall current(I) in the circuit:
I = I1 + I2
I = 2 + 2 = 4A.
From the illustrations above, we can see that the same current will flow through each bulb as the will current split into two equal parts
Answer: summer and greater than 66°N
Explanation:
Summer is the most appropriate season in which the sun does not set. It is a typical situation for the Arctic Circle. It is the latitude in which the sun does not set in the day and typically during the month of July. The north of this circle is a period of sunshine which last for a period of about six months in the North Pole. Summer never rises in the winter solstice (December).
