“Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom”
“Every magnet has both a north and a south pole. When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.”
Answer:
Its position after 4 seconds is 62 meters.
Explanation:
It is given that,
The acceleration of the particle is given by equation :

Also, 



At t = 0,
. So, c = 3

Also,
, s is the position



At t = 0,
. So, c' = 10

At t = 4 s

s = 62 m
So, at t = 4 seconds the position of the particle is 62 meters. Hence, this is the required solution.
Answer:
110.25 J
Explanation:
We are given that
Mass,M=2.5 kg
Radius,R=0.5 m
Distance,d=4.5 m
Initial speed,u=0
We have to find the total kinetic energy
According to law of conservation of energy
Total kinetic energy=Potential energy=mgh
Where g=
Using the formula
Total kinetic energy=
Total kinetic energy
maybe yes/maybe No.
Explanation:
cause if the person need a good grades he will going to grab all that he need to grab as a student and studies her lesson.
cause all person has their own reason why he did not do her activity or project because we have a different situations and life..
Answer:
Explanation:
capacitance of each capacitor
C₀= Q₀ / V₀
V₀ = Q₀ / C₀
New total capacitance = C₀ ( 1 + K )
Common potential
= total charge / total capacitance
= 2 Q₀ / [ C₀ ( 1 + K ) ]
2 V₀ / ( 1 + K )
b )
Common potential = 2 x V₀ / ( 1 + 7.8 )
= .227 V₀
charge on capacitor with dielectric
= .227 V₀ x 7.8 C₀
= 1.77 V₀C₀
= 1.77 Q₀
Ratio required = 1.77
