from W-Z.. i think on a swing you get your most potential energy at W and Z is where you go up so Z would be where the kinetic energy increased and W is where potential energy decrease

Manuel traveled 3 hours nonstop to Mexico, a total of 197 miles. He took a train part of the way, which averaged 70mph, and t

Anton [14]

Answer:

1.7 hours

Explanation:

Time taken in the journey = 3 hours

Distance of the entire journey = 197 miles

Distance travelled on train = x

Distance travelled on bus = 197-x

Average speed of train = 70 mph

Average speed of bus = 60 mph

Time = Distance / Speed

$\frac{x}{70}+\frac{197-x}{60}=3\\\Rightarrow \frac{6x+1379-7x}{420}=3\\\Rightarrow -x+1379=3\times 420\\\Rightarrow -x=1260-1379\\\Rightarrow x=119\ miles$

Distance travelled by train = 119 miles

Time taken on train = 119 / 70 = 1.7 hours

Manuel spent 1.7 hours on the train

Find the electric force acting on an alpha particle in a horizontal electric field of 600N/C

Sergeeva-Olga [200]

Since an alpha particle has 2 protons and no negative particles (electrons) to balance the net charge, its charge is
Q=2(1.6e-19)=3.2e-19C.
The force on a charged particle is F=QE so
(3.2e-19C)(600N/C)=1.92e-16N
