Answer:
Limewater can be used to detect carbon dioxide. If carbon dioxide is bubbled through limewater then it turns from clear to cloudy/milky in colour. This is why limewater used in a simple respirometer can show that more carbon dioxide is present in exhaled air compared to inhaled air.

(b)
Answer:
-0.64525g
Explanation:
t = Time taken for the car to stop
u = Initial velocity = 95 km/h
v = Final velocity = 0 km/h
s = Displacement
a = Acceleration
Equation of motion
Converting to m/s²
g = Acceleration due to gravity = 9.81 m/s²
Dividing both the accelerations, we get
Hence, acceleration of the car is -0.64525g
Answer:
6.65×10⁻⁷ s
Explanation:
Speed of light in water = Total distance traveled in water/time
c = d/t ....................... Equation 1
Where c = speed of the light pulse in water, d = distance traveled in water, t = time.
also
c = v/n ..................... Equation 2
Where v = speed of light in air, n = refractive index of water
Substituting equation 2 into equation 1
v/n = d/t
making t the subject of the equation,
t = nd/v.................. Equation 3
Given: 150 m.
Constant: n = 1.33, v = 3.0×10⁸ m/s
Substitute into equation 3
t = 1.33(150)/3.0×10⁸
t = 6.65×10⁻⁷ seconds.
Hence the time = 6.65×10⁻⁷ s
