The silver coating on the inner bottle prevents heat transfer by radiation, and the vacuum between its double wall prevents heat moving by convection. The thinness of the glass walls stops heat entering or leaving the flask by conduction.
average velocity is vector displacement / time
time is "almost exactly one hour"
disp = -10m
v= -10/1x60x60 = -1/360m/s
Explanation:
m = mass of burrito thrown by the student = 0.5 kg
a = acceleration of the burrito thrown by the student = 3 m/s²
F = force applied by the student on the burrito = ?
According to newton's second law , the net force on an object is the product of its mass and acceleration. it is given as
F = ma
inserting the values
F = (0.5) (3)
F = 1.5 N
hence the net force on the burrito comes out to be 1.5 N
