Do you think a moving skateboard has energy? Why or Why not? What about a skateboard that is not moving?

Answers

Answer 1
Yes,

because it is moving which generates energy. ... Does a moving skateboard have energy? To move the energy, you had to transfer the potential energy to kinetic energy. This generates heat, light, or sound.

Mahiya and Mrinmoy are in a relay around a square field with each side of length 60m. First, Mahiya runs at a speed of 6 ms−1 for 60m to pass a baton to Mrinmoy. Then Mrinmoy runs 120m at 4ms−1 while Mahiya runs through the field to reach the other corner. Then Mrinmoy passes the baton. But Mahiya is now tired since she has been constantly running. So, she only runs at 3ms−1 for the final 60m. What is the average speed of the baton in ms−1?

Answers

The average speed of the baton can be determined by dividing the total distance travelled by the total time taken for that travelling.

[tex]Average\ Time = \frac{Total\ Distance}{Total\ Time}[/tex]

First, we will find the total distance, by adding the distances travelled by both Mahiya and Mrinmoy, while carrying the baton.

[tex]Total\ Distance = Distance\ Travelled\ by\ Mahiya\ to\ pass\ the\ baton\ to\ Mrinmoy\ +\ Distance\ Travelled\ by\ Mrinmoy\ to\ pass\ the\ baton\ to\ Mahiya\ +\ Final\ Distance\ Travelled\ by\\ Mahiya[/tex]Total Distance = 60 m + 120 m + 60 m = 240 m

Now, we will find the total time taken for this travelling. To find out the total time we will divide each distance travelled by the speed of the traveller during that distance:

[tex]Total\ Time = \frac{60\ m}{6\ m/s}+\frac{120\ m}{4\ m/s}+\frac{60\ m}{3\ m/s}\\\\Total\ Time = 10\ s\ +\ 30\ s\ +\ 20\ s[/tex]

Total Time = 60 s

Now, we finally find the average speed of the baton by using the formula:

[tex]Average\ Time = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Time = \frac{240\ m}{60\ s}[/tex]

Average Speed = 4 ms⁻¹

Sonia O'Sullivan of Ireland set the World Record in 1994 for the Women's 1000 m race with a time of 2 minutes and 45 seconds. What was her average velocity?​ ill give brainliest

Answers

Answer:

Sonia O'Sullivan (born 28 November 1969) is an Irish former track and field athlete. She won a gold medal in the 5000 metres at the 1995 World Championships, and a silver medal in the 5000 metres at the 2000 Olympic Games.[1] Her 2000 m world record of 5:25.36, set in 1994 stood until 2017.[2]

O'Sullivan first came to prominence when winning the 1500 m at the 1991 Universiade, before going on to finish fourth in the 3000 m final at the 1992 Olympic Games. She then won a silver medal in the 1500 m at the 1993 World Championships. She was the favourite for the 5000 m title at the 1996 Olympic Games but dropped out of the final due to illness. As well as her 1995 World title, she won three gold medals at the European Championships, in the 3000 m (1994), 5000 m (1998) and 10,000 m (1998), and is a two-time World Cross Country Champion.

O'Sullivan won silver medals in the 5000 m and 10,000 m at the 2002 European Championships, and competed at her fourth Olympic Games in 2004. She is known for her dramatic kick, clocking 28-second final 200 m splits in some of her races.[3]

She is the one of two women (the other Tirunesh Dibaba) who won the short and long course World Cross Country title at the same championship (1998 in Marrakesh).[4]

Answers

Liquid
Not sure
Good luck
I don't know
Yogurt is something that can't exactly be categorized into liquid or solid. It can be a liquid, because it does eventually take up the space you put it in (like water does). But it can also be a solid, because it is fairly firm (like a brick).

A bus has velocity of 20 m/s towards east and another bus has velocity of 15 m/s in west direction . if they start to move from a point simultaneously, what distance do they cover in 2 minutes ? what will be their seperation ?

Help plss!!

Answers

Answer:

3.8 km

Explanation:

Eastern Side Bus

Velocity = 20m/s

Covers distance in 2 min (120sec) = 20×120 = 2400m = 2 km

Western Side Bus

Velocity = 15m/s

Covers distance in 2 min (120sec) = 15×120 = 1800m = 1.8 km

Separation Distance = 2+1.8 = 3.8 km

3.8 kilometers or km

Abid is the hare who runs fast and takes long rest while Gautam runs slow but takes short rest. Abid can run at 5 ms−1 while Gautam runs at 3 ms−1 . Abid has to take a 10s break after running 20s. But Gautam can take a 10s break after 90s. They are running a 1km (1000 m) race. What is the time difference between winner and loser? (Write the value in seconds upto nearest whole number)

Answers

Guatam is the fastest the other was the slowest
Abid
Velocity = 3 m/s
Can take a break for = 10s
Takes a break after = 20s

Time taken to run 1000m without breaks = 1000/5 = 200s

Abid takes 200s to run 1km without any breaks

If he takes a break after every 20s,
Then, number of breaks he takes = 200s/20s = 10 breaks

Time he spend in every break = 10s
Amount of time spent specifically in breaks = 10breaks * 10 s = 100s
Time inclusive of breaks = 200s + 100s = 300s

Hence Abid takes 300s with breaks


Gautam
Velocity = 3 m/s
He can take a break for 10s
He has to take a break after running 90s

Time taken without breaks = 1000m / 3 ms-1 = 333.3s
Time taken for Gautam to cover 1km without any breaks = 333.3s

He can take a break after running for 90s
Number of brakes he can take = 333.3s / 90s = 3.703 breaks
He can take 3.703 breaks in his entire journey

Amount of time he can spend in his break = 10s
Amount of time wasted = 3.703breaks * 10s = 37.03s

Total time = 333.3s + 37.03s = 370.39s

Rounding off = 370s
Hence, Gautam reaches the end of 1km faster than 1km

Difference = 370s - 300s = 70s

Question 3 (Essay Worth 5 points)
A train leaves the station heading south on the tracks. It takes the train 5 seconds to reach 50 miles per hour. It completes the entire 100 mile trip in two hours. Calculate the train's average speed and velocity over the two hour trip. Show your work. Identify if each of the measurements are a scalar or vector quantity.

Answers

Well, in order to figure Out the answer is to divide until you figure out how many miles they went per second. If it takes five seconds to reach 50 mph it’s a 10 seconds per every 10 miles meaning each mile took one second.So, if it finished hundred mile trip in two hours it took an hour for 50 miles. If it took one hour and 50 miles divide 60/50 which gets you 1.2 Miles per minute meaning the car went 120 miles Per hour
