Answer: d boiling water
Explanation: the water is boiling and bubbling cause the molecules are so fast and they hit off each other
The only correct statement on that list is <em>choice-C</em>: If a positively charged rod is brought close to a positively charged object, the two objects will repel.
If you repeat the experiment, you will want to do it the same way to see if the results change.
HOPE THIS HELPS!!!
Answer:
6.54 × 10⁻⁵ Pa-s
Explanation:
Since the shear force, F = μAu/y where μ = viscosity of fluid between plates, A = area of plates, u = velocity of fluid = 0.6 m/s and y = separation of plates = 0.02 mm = 2 × 10⁻⁵ m
Since F = μAu/y
F/A = μu/y where F/A = force per unit area
Since we are given force per unit area, F/A = 1.962 N per unit area = 1.962 N/m²
So, μ = F/A ÷ u/y
substituting the values of the variables into the equation, we have
μ = F/A ÷ u/y
μ = 1.962 N/m² ÷ 0.6 m/s/2 × 10⁻⁵ m
μ = 1.962 N/m² ÷ 0.3 × 10⁵ /s
μ = 6.54 × 10⁻⁵ Ns/m²
μ = 6.54 × 10⁻⁵ Pa-s
Answers:
a) Momentum for Car 1: 
East
Momentum for Car 2:
West
b) Car 2 has the greater momentum
Explanation:
a) The linear momentum 
is given by the following equation:
(1)
Where 
is the mass of the object and 
its velocity.
In this case both cars have a mass of 
but different velocities (
east for car 1 and 
west for car 2).
For Car 1:
(2)
(3)
(4)
For Car 2:
(5)
(6)
(7)
b) Having the result of the lineal momentum for both cars, we know Car 2 has the larger momentum, this can be known because Car 2 has a greater velocity.
So, if momentum is directly proportional to the mass and the velocity of the object, both objects have the same mass but different velocities; the object with greater mass will have the greater momentum.
