A bicycle is heading West. It goes 5000m in 500s what's its velocity
dybincka [34]
There are several information's of immense importance already given in the question. Based on the given information's the answer to the question can easily be determined.
Distance covered by the bicycle = 5000 meter
Time taken by the bicycle to reach the distance = 500 second.
Velocity of the bicycle = Distance / Time taken
                                   = 5000/500 meter/second
                                   = 50 meter/second
So the velocity of the bicycle is 50 meter per second. I hope the procedure is clear enough for you to understand. In future you can always use this procedure for solving similar problems.

Calculate the potential difference of a wire of 10 ohm , through which 5 A of current is flowing .
HACTEHA [7]
Resistance= Potential Difference/Current
10 Ohm= PD/ 5A
PD= 10 Ohm × 5A
PD=50
Therefore, Potential Difference is B. 50 V

2. Superman is able to fly at an average velocity of 355 m/s. If he begins at a position of
lesya [120]

Answer:

final position = 325 m

Explanation:

distance covered in 1 second = speed x time

                                                 = 355 m/s  x   1 s

                                                 = 355 m

∴  final position =  initial position + distance covered

                          =  - 30 m  +  355 m

                          =  325 m

Why can’t the high-quality energy released from a lump of burning coal be recycled?
snow_tiger [21]

Answer:

when energy changes from one form to another, it always goes from a more useful to a less useful form. This means that people can't recycle or reuse high quality energy to perform useful work.

A car starting from rest accelerates uniformly at 4.3 m/s^2 for 5.0 seconds. How far does the car move?
andreev551 [17]

Answer:

Vf = 21.5 [m/s]

Explanation:

To solve this problem we must use the following kinematics equation:

v_{f}= v_{i} +(a*t)\\

where:

Vf = final velocity [m/s]

Vi = initial velocity = 0

a = aceleration = 4.3 [m/s^2]

t = time = 5 [s]

Now replacing:

Vf = 0 + (4.3*5)

Vf = 21.5 [m/s]
