There are four types of fundamental forces in nature.These are named as gravitational force,electromagnetic force,strong nuclear force and weak nuclear force.
As per the question we have to understand the role of strong nuclear force and weak nuclear force.
An atom consists of a nucleus surrounded by extra nuclear part consisting of electrons in various orbits.The nucleus contains two basic particles called protons and neutrons .Protons are positively charged while neutrons are neutral.Protons being positively charged will impart repulsive force on each other and may come out of the nucleus.But the nucleus is stable.That is due to the strong nuclear force.
Strong nuclear force is a spin dependent and charge independent force which comes into existence due to the mutual interaction of gluons which binds the protons and neutrons .Hence it is attractive in nature.It's 100 times more stronger than electromagnetic force also.
Weak nuclear force comes into existence during radio -active decay .This force is due to the exchange of ' w' and 'z' bosons[the particles like protons and neutrons having integral or zero spin] which are heavier in nature.The role of it is to change protons into neutrons and vice versa.Its a short range force.
Hence the option D is right.
Answer: Δx = vxt = (85 m/s)(9s) = ? m
Explanation:
If the plane is in level flight,
Δx = vxt = (85 m/s)(9s) = ? m
Note that if Δx ≠ 0, it will not land on the car.
Answer:
a).
The magnitude force impulse is
the average force is
Explanation:
Using the conservation energy the potential energy in the high is equal to the kinetic energy just before the collision so:
Notice the mass can be cancel as a factor so:
Now the impulse is determinate by:
The average force is also
Yes
Explanation:
Blowing a room-temperature air over an ice block will heat it because of convection.
Convection is one of the heat transfer modes that occurs in fluids.
- In convection, a hot and lighter fluid replaces a denser and cold fluid.
- It involves the actual motion of the particles of the medium.
- In this analogy, the blowing room-temperature is hot and lighter.
- It will replace the air close to the ice block body that is cold and denser
- As the hot air comes near the ice block, it loses some of its heat and warms the cold ice.
- In turn, the air becomes colder and moves away.
- This is simple convection in action.
