Answer:
.7934
Explanation:
Acceleration = change in velocity / change in time
A = 10.98
/ 13.84
A = .7934
When hot tea is mixed to chilled coke, tea loses heat and coke gains heat. Thus, tea cools down but coke gets heated. Because it is liquid and liquid does not totally cool down to the ambient temperature, it and the iced drink will eventually reach the same temperature.
In the absence of air resistance , object fall with <u>same acceleration</u> .
Answer:
0.855 N
Explanation:
Using
F = BILsinФ.................... Equation 1
Where F = magnitude of the force exerted on the wire, B = magnetic Field, I = current, L = Length of the wire in the magnetic Field, Ф = angle between the wire and the magnetic field.
Given: B = 0.95 T, I = 15.0 A, L = 2r, r = radius = 3.0 cm = 0.03 m L = 2×0.03 = 0.06 m, Ф = 90° (perpendicular)
Substitute into equation 1
F = 0.95(15)(0.06)sin90°
F = 0.855 N.
Hence the magnitude of force that is exerted on the wire = 0.855 N
