Answer:
Explanation:
The simplest circuit has the battery in series with the resistor
V = IR
I = V/R = 1.5 / 15 = 0.10 Amps
It could be 1.5 / 150 = 0.01 A depending on how one assumes an error or not in "150hm"
I believe I seen on google if you go to Mather
The equation to work out the speed is distance/time.
If we apply this equation to your numbers we will first need to find the total distance travelled.
80km/h for an hour means you travel 80km
40km/h for 2 hours means you will travel 80km
80+80 is 160km in total.
The time taken to complete this distance is 3 hours so, applying the equation we get
speed = 160/3 = 52.33km/h
B) 20 cm
The height and distance will be the same. Only the image will be laterally inverted.
Answer:
A balance
Explanation:
Scientists measure mass with a balance, such as a triple beam balance or electronic balance. In science, the volume of a liquid might be measured with a graduated cylinder.
