Plz I need help!! 18- Consider the circuit represented in
figure 16.
The dry cell maintains a constant
voltage Upx=9 V; Ri=100 12 and
R2200 2
a Find the resistance of the resistor
equivalent to the two resistors.
b- Calculate the current sent by the dry
cell
Calculate the voltages UI and Uz across
Ri and R2 respectively. Verify the law of
addition of voltages

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
