Do cars get better gas mileage with clean air filters? Gas mileage for 10 cars with dirty air filters and clean air filters was

studied. Each car was tested with a clean air filter and once with a dirty air filter (with the order of the testing randomized). What type of study is this?
Physics

8 0

Answer:

Explanation:

Yes.

Proper maintenance of cars or any vehicle will add more life to it and increase the quality performance.

If dirty filters of cars is changed, the gas mileage will increase resulting into a better performance of cars.

Dirty air filters reduces the capacity for it to filter the air going into engine. If air filters are not changed for a longer time it results into misfire or trouble starting.

Two blocks are connected by a light weight, flexible cord that passes over a frictionless pulley.Ifm1=2 kg and m2 = 3 kg, and bl
Vera_Pavlovna [14]

Answer:

t = 1.41 sec.

Explanation:

If we assume that the acceleration of the blocks is constant, we can apply any of the kinematic equations to get the time since the block 2 was released till it reached the floor.

First, we need to find the value of  acceleration, which is the same for both blocks.

If we take as our system both blocks, and think about the pulley as redirecting the force simply (as tension in the strings behave like internal forces) , we can apply Newton's 2nd Law, as they were moving along the same axis, aiming at opposite directions, as follows:

F = m₂*g - m₁*g = (m₁+m₂)*a (we choose as positive the direction of the acceleration, will be the one defined by the larger mass, in this case m₂)

⇒ a = (\frac{(m₂-m₁)}({m₁+m₂} * g = g/5 m/s²

Once we got the value of a, we can use for instance this kinematic equation, and solve for t:

Δx = 1/2*a*t² ⇒ t² = (2* 1.96m *5)/g = 2 sec² ⇒ t = √2 = 1.41 sec.
