Students are given some resistors with various resistances a battery with internal resistance

Explanation

Explanation:

V  = emf − Ir ,

where r is the internal resistance and I is the current flowing at the time of the measurement.

I is positive if current flows away from the positive terminal. The larger the current, the smaller the terminal voltage.

Resistances is series add  the total resistances

while in parallel reduces .

the pull of gravity on the rocket decreases

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
