Why is the curve between 1950 and 1980 relatively flat and centered around zero degrees difference from the baseline? (Hint: how is the temperature change being compared over time?)

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f
