1. First determine the suitable formula for this word problem. Which is a. A=vf-vi/t

Given are: Vf=99.2 km/h Vi= 0.0 km/h T= 4.0sec

Solution:
A= 99.2 km/h – 0.0km/h / 4.0 sec
A = 99.2 km/h / 4 sec
A = 2.8 km/h/sec

Answer:

24.8 km per second

A _______ satellite records reflected wavelengths from Earth's surface.

Answers

A visible satellite images records reflected wavelengths from Earth's surface.

Visible satellite images record visible light coming from the sun that is reflected by clouds, land, oceans or snow and ice.
There is a big difference between visible and infrared images since visible images record reflected light rather then emitted radiation.

Why do the track runners start at different positions on the track?

Answers

Track runners start at different positions on the track to ensure that each runner covers the same distance during the race.

In track events, particularly in sprints, the distance to be covered is the same for all competitors (e.g., 100 meters, 200 meters, 400 meters, etc.).

To compensate for the curved shape of the track, which can create unequal distances for runners in outer lanes compared to those in inner lanes, runners start from staggered positions. The lanes closer to the inner part of the track have a smaller radius and, therefore, a shorter distance to cover in each lap compared to the outer lanes.

By starting at staggered positions, each runner has an equal distance to run during the race. This helps ensure fairness in the competition and eliminates the advantage that could be gained by running in a specific lane.

The starting positions are determined based on the lane number, with the innermost lane (lane 1) starting at the shortest distance from the finish line and the outermost lane starting at a greaterdistance to compensate for the curvature of the track. This ensures that all runners have an equal opportunity to perform at their best regardless of the lane they are assigned to.

Hence, Track runners start at different positions on the track to ensure that each runner covers the same distance during the race.

A car traveling at 37 m/s starts to decelerate steadily. It comes to a complete stop in 6 seconds.what is its acceleration? m/s

Answers

Magnitude of acceleration = (change in speed) / (time for the change)

= (end speed - start speed) / (time for the change)

= (0 - 37 m/s) / (6 sec)

= ( - 37 / 6) (m/s²)

= - 6-1/6 m/s²

= -6.1667 m/s² (rounded)

Suppose you decide to cut the wire into two pieces (not necessarily the same length) to shape into two circles. Write a function A ( x ) which models the total area of the two circles in terms of x , the length of one of the pieces of wire. (It may be helpful to use for a circle A = πr 2 and C = 2 πr ). Then find the length x that will minimize the total area.
