Answer:
a) t = 4.04 s
, b) x = 89.77 m
Explanation:
This is a one-dimensional kinematics exercise.
a) Let's use caution to find the time, the vehicle speed when stopped is zero
v = v₀ - at
let's reduce the magnitudes to the SI system
v₀ = 160 km /h (1000m / 1km) (1h / 3600s) = 44.44 m / s
0 = v₀ - at
t = v₀ / a
t = 44.44 / 11
t = 4.04 s
b) to calculate the distance traveled we use
x = v₀t - ½ a t²
x = 44.44 4.04 - ½ 11.0 4.04²
x = 179.54 - 89.77
x = 89.77 m
Answer:
A. A login vty mode subcommand
Explanation:
since we are protecting co-workers from connecting to the switches from their desktop PCs, we would need a Telnet line which is used to connect to devices remotely from other network devices on the same network segment as the device we want to connect to. A login local vty subcommand configures a local username for login access but since our design constraint is to configure without usernames, option A is the correct answer.
One very useful definition if energy is "the ability to do work".
The answer to the first question is C isotonic environment. To help me learn this I memorized that isotonic is equal hypotonic is over hydrated while hypertonic is dehydrated. And for the second question is they move from high to low so C
Answer: B
Explanation:
The equation to find momentum is velocity*mass. Without velocity, there would be no momentum. Therefore the object CAN NOT be at rest.
