Answer: 4.45m/s
Explanation:
I assume we're solving for her speed.
400m x 4 laps = 1600m
1600m / 6 minutes = 266.67m/min
(266.67m/min) x (1 minute/60 seconds) = 4.45m/s
266.67/60 = 4.45m/s
Reflection. I used the process of elimination. Cleavage and color are properties of a mineral and magnetism is a property as well you just can’t find strong traces of it in all minerals. But it’s there no matter how weak or strong it’s attraction is drawn to magnetic fields.
Answer:

Explanation:
We are asked to find the final velocity. We are given the acceleration, time, and initial velocity, so we can use the following kinematics formula.

In this formula,
is the final velocity,
is the initial velocity,
is the acceleration, and
is the time.
The bicycle has an initial velocity of 5.0 m *s⁻¹ or m/s, acceleration of 2 m/s², and a time of 5 seconds.

Substitute the values into the formula.

Solve inside the parentheses.

Add.

The units can also be written as:

The bicycle's final velocity is 15 meters per second.
Aperture is measured in F-stops, in which the f-stops is the amount of light allowed to pass through the aperture, which simply put means that the smaller the aperture, the higher the f-stops. What it does is reduce the amount of light that reaches the film, so the higher the f-stops, the less light reaches the film.
