Answer: The ice and shel are at the same temperature.
Explanation: Conduction happens when you have two objects at different temperatures touching each other, in this case, the temperature flows from the hot object to the cold one, until the equilibrium is reached (this means that both objects are at the same temperature). So, in order to conduction to happen, we need a difference in temperature and direct contact. So there are two options of the given that can be the answer: "There is no direct contact" In the sentence says that "the ice is placed on the freezer shelf", so we have direct contact between both objects. "The ice and shelf are at the same temperature" Here both objects are inside of the freezer, so we can expect that both of them are at the same temperature, hence, there is no conduction.
Answer: actually to solve this u must know what 3.2m/s2 is..do u know it ??...wel let me tell...3.2m/s2 means that in every second the speed of the body increases by 3.2m/s..so if it acts for 6.8 seconds..increase in speed will be 3.2*6.8 however note that this is the increase in speed.. have to change this in km/hr & add this to the initial speed(27km/hr) to get the answer....hope this has cleared ur doubts....
Explanation:
Answer
given,
width of slit, d = 0.08 mm
d = 8 x 10⁻⁵ m
light of two wavelength
I₁= 446 nm
I₂ = 662 nm
a) angles at which the third dark fringe
m = 3 , I₁= 446 nm
C = 0.958°
m = 3 , I₁= 662 nm
C = 1.423°
b) angles at which the third dark fringe
m = 1 , I₁= 446 nm
C = 0.319°
m = 1 , I₁= 662 nm
C = 0.474°
Answer:
Explanation:
The definition of acceleration is the change in velocity over a period of time. If the girl's velocity is constant, that means it's not changing. Therefore, acceleration is 0 m/s/s
