Answer:
I am going to say A
Explanation:
solids are normally close and tightly packed molecules and while ice is in solid form,so is it.
Let me know if i was right! Hope this helps! :)
Answer:
E= 3.4893 N/C
Explanation:
Given s=6.20 m , t=2.50μs, m=9.11*10^-31 Kg , q= 1.6*10^-19 C
the distance traveled by the electron in time t is
s=ut+0.5at^2
here, u is the initial velocity of the electron, t is time taken and
a is acceleration.
Since the electron is initially at rest u=0
now s=0.5at^2
Therefore a=2s/t^2
also. we know that strength of electric field is
E=ma/q
now puting the values we get
therefore, E= 3.4865 N/C
Answer:
i am sorry :( there is the app khan academy where you could learn things like that
Explanation:
Answer:
B. parents
Explanation:
one of the conclusions from Einsteins relativity theory for his equation E= (where E is energy, m is mass and C is the speed of light),
is that time moves relative to the observer. Time moves more slowly when the observer is in motion (time dilation), therefore an individual in motion ages more slowly than someone at rest. This in fact happened when astronaut Scot Kelly spent nearly a year on board the international space station and on his return, his twin brother had aged slightly faster than him. In conclusion, if a space trip finds a son or daughter is biologically older than his or her parents, the space trip was taken by the parents.
