A box-shaped wood stove has dimensions of 0.75 m x 1.2 m x 0.40 m an emissivity of 0.81, and a surface temperature of 210 degree C. Calculate its rate of radiation into the surrounding space. Please show all work.
Assuming that the earths core has a density of 5000 Kg/m3, core radius of 106m and charge density of 1C/m3 and modeling the core as a solid sphere what is the angular velocity of the core? Does the number make sense?
How far down the road from the initial point that they passed each other will the cop catch the car?
If, in the course of an hour, the frog spends 32% of the time resting and 68% of the time performing identical jumps of that maximum length, in a straight line, what is the distance traveled by the frog?
A 1280-kg car pulls a 350-kg trailer. The car exerts a horizontal force of 3600 N against the ground in order to accerlerate. What force does the car exert on the trailer? Assume an effective friction coefficient of 0.15 for the trailer.
When 200g of aluminum at 100° c is dropped into aluminum calorimeter of mass 120 g and containing 150g kerosene at 15° C, the mixture reaches at temperature of 50° C. What is the specific heat of kerosene?
What must be (a) the magnitude and (b) the direction of the third force, such that the object continues to move with a constant velocity? Express your answer as a positive angle south of east.
Space vehicles traveling through Earth's radiation belts can intercept a significant number of electrons. The resulting charge buildup can damage electronic components and disrupt operations.
Three point charges lie along a straight line as shown in the figure below, where q1 = 5.76 µC, q2 = 1.44 µC, and q3 = -2.2 µC. The separation distances are d1 = 3.00 cm and d2 = 2.00 cm. Calculate the magnitude and direction of
