Answer:
I can give you a list of noncontact forces off of my head, if that is what you need.
Explanation:
First, gravity. It acts everywhere and pulls down every object that is in the air towards the ground, unless they have an equal and opposite force that counters it.
Second, wind. I don't think this will count because wind is a physical thing, but it can be used in the same way as we did with gravity. If the force counteracting it is larger, equal, and opposite of the force it is countering, then it will move forward, through the wind.
Answer:
correct answer is option A and B are correct.(an electron groups consist of bonded pairs of electrons and Lone-pair electrons )
Explanation:
An electron group is a group of electrons. An electron groups consist of bonded pairs of electrons and Lone-pair electrons . Electron can have single bond, double bond or they can have triple bond.
Therefore both option A and B are correct.
Explanation:
2. momentum(p) = mass*velocity
Force(F)=mass*acceleration
Inertia is the tendecy of an object to resist changes to its state.
4. F= ma
50kg*15m/s2 =750N
5.F=ma
10kg * 3m/s2 =30N
6. P=mv
10kg * 3m/s =30 kg.m/s
Work = (force) x (distance)
If the distance is zero (the object doesn't move), then it
doesn't matter how great the force is. The work is still zero.
<span>Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record</span>
