Since the acceleration of car is uniform so the distance traveled by car while brakes are applied is given by
given that
now plug in all data in above formula
so car will cover 14.4 m distance while it apply brakes

I wish I could help but iam srry
Answer:
a = 16.5 x 10⁻⁶ m = 16.5 μm
Explanation:
Here we will use the diffraction equation:
y = mλL/a
where,
y = distance between two consecutive dark fringes = 5.34 cm = 0.0534 m
m = order of diffraction = 1
λ = wavelength of light = 633 nm = 6.33 x 10⁻⁷ m
L = Distance between hair and screen = 1.4 m
a = thickness of hair = ?
0.0534 m = (1)(6.33 x 10⁻⁷ m)(1.4 m)/(a)
a = (6.33 x 10⁻⁷ m)(1.4 m)/(0.0534 m)
<u>a = 16.5 x 10⁻⁶ m = 16.5 μm</u>
I would say that all of the above are correct but I'm not sure. hope this helps :)
Answer: The correct option is "They must be cooler than the air inside the house".
Explanation:
Thermal energy flows from the body at higher temperature to the body at the lower temperature.
In the given problem, the metal aluminum coils in an air conditioner conducts thermal energy from inside the house. The coils must be cooler than the air inside the house.
The thermal energy flows from inside the room to the coils in an air condition. Then, the thermal energy flows from the metal aluminium coils to outside the house.
