The average time that it takes for the car to travel the first 0.25m is 2.23 s
The average time that it takes for the car to travel the first 0.25 m is given by:
The average time to travel just between 0.25 m and 0.50 m is 0.90 s
First of all, we need to calculate the time the car takes in each trial to travel between 0.25 m and 0.50 m:
Then, the average time can be calculated as
Given the time taken to travel the second 0.25 m section, the velocity would be 0.28 m/s
The velocity of the car while travelling the second 0.25 m section is equal to the distance covered (0.25 m) divided by the average time (0.90 s):
Answer:
an exhaust leak is most likely in your systems manifold or any of the joints along the exhaust system if the leak is the manifold not only will your engine volume increase. but some of them can be located and a running vehicle in the engine bay
Explanation:
lol hope it helps^^ I'm no expert but I'm just giving info
Answer:
25J
Explanation:
power = work done ÷ time taken.
and work done = force applied × distance covered.
according to the question, the athlete lifts the weight of 100N upto 5m therefore;
100N × 5m = 500N/m
then onwards,
the work done (500 N/m) should be divided by the time taken to calculate the power,
500 ÷ 20s = 25J
is your answer.
hope this helped. :)
An athlete produced 840 watts of power in 0.6 seconds. And will produce 504 joule of work did this individual perform during the exercise.
<u>Solution:</u>
we know that power is the work done completed in a given interval of time.
Power = 
also, Work = Power × Time
Work = 840 × 0.6 = 504 joule
What is Power?
- The quantity of work that can be accomplished in a certain amount of time is measured by power.
- Power is expressed in joules per second (J/s) this is because work is denoted by the symbol J and time by the symbol s.
- This is the watt, which is also known as the power unit in SI (W). One joule of labor per second is equal to one watt.
- The number of watts that a device uses is indicated on labels for lightbulbs and other small appliances like microwaves.
- A force must be applied in order for work to be completed, and there must also be motion or displacement in the force's direction.
- The amount of force multiplied by the distance moved in the force's direction is known as the work done by a force acting on an item. Work has no direction and only magnitude. Work is a scalar quantity as a result.
