Answer:
W has the lowest density and Y has the greatest density
Explanation:
Density of W = mass/volume = 11/24 = 0.45
Density of X = mass/volume = 11/12 = 0.91
Density of Y = m/v = 5.5/4 = 1.375
Density of Z = m/v = 5.5/11 = 0.5
From these we can find the answer......
Hope this answer is useful......
Assuming the driver starts slamming the brakes immediately, the car moves by uniformly decelerated motion, so we can use the following relationship

(1)
where
a is the deleceration
S is the distance covered after a time t

is the velocity at time t

is the initial speed of the car
The accident is 80 m ahead of the car, so the minimum deceleration required to avoid the accident is the value of a such that S=80 m and

(the car should stop exactly at S=80 m to avoid the accident). Using these data, we can solve the equation (1) to find a:

And the negative sign means it is a deceleration.

Explanation:
Same numbers of protons but different number of neutron so i would go for A same atomic number different number of neutrons
Athletes of any kind can use technology to monitor things like their BMI (body mass index) or weight or anything of the sort to target what they need to work on to improve their health.
