At which of the following angles will the sunlight received at a location on earth spread out over the largest area? 1- 90° 2- 70° 3- 40° 4- 10°

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

In an experiment, how can i change human errors? be specific.

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
