Answer:
6.758V
Explanation:
The computation of the final speed of the defender/ball carrier mass is shown below:-
Data provided in the question
Measurement of ball = 75 kg
Right m/s = 6.5 m/s
Defender = 80 kg
Carrying running 7.0 m/s
Based on the above information, the final speed of the defender or ball carrier mass is
As we know that
Conservation of momentum is
= Ball in Kg × Right m/s + Defender in Kg × running m/s
= 75 × 6.5 + 80 × 7
= (75 + 80)V
Therefore, the Final speed = 6.758V
You know I’m going to be honest I don’t feel like it
Answer:
Image B represents the force on a positively charged particle caused by an approaching magnet.
Explanation:
The most fundamental law of magnetism is that like shafts repulse each other and dissimilar to posts pull in one another; this can without much of a stretch be seen by endeavoring to put like posts of two magnets together. Further attractive impacts additionally exist. On the off chance that a bar magnet is cut into two pieces, the pieces become singular magnets with inverse shafts. Also, pounding, warming or winding of the magnets can demagnetize them, on the grounds that such dealing with separates the direct game plan of the particles. A last law of magnetism alludes to maintenance; a long bar magnet will hold its magnetism longer than a short bar magnet. The domain theory of magnetism expresses that every single enormous magnet involve littler attractive districts, or domains. The attractive character of domains originates from the nearness of significantly littler units, called dipoles. Iotas are masterminded in such a manner in many materials that the attractive direction of one electron counteracts the direction of another; in any case, ferromagnetic substances, for example, iron are unique. The nuclear cosmetics of these substances is with the end goal that littler gatherings of particles unite as one into zones called domains; in these, all the electrons have the equivalent attractive direction.
Answer:The source of all wave motion is a disturbance in matter or a vibration. Think about a water wave.

Explanation:
The average speed is :
Now, how many seconds are in 10 months? We know that there are 31 days in seven months (January, March, May, July, August and October), 30 days in three months ( April, June and September) and 28 days in February. This gives us:
Now, in every day there are 24 hours. So, the total number of hours will be:
So, the speed will be:
To convert this to m/s we can use the conversion factors:
