Of course! Why not? Explain why? Um, because girls are capable of doing things.
Answer:
The deceleration is 4 times higher for 0.5sec than for 2 sec.
Explanation:
If the deceleration happens from 1800deg/sec to zero in 2 sec we have that the magnitude is:

if now the time to decelerate is 0.5sec:

The deceleration is now 4 times higher than the previous situation.
Answer:

Explanation:
ri = 0.20cm
ro = 0.4 cm
length L = 13m
resistivity \rho = 2.00*10^13 ohm m
resistance can be determine by using following relation



The formula is CaCl2 as you need two Cl ions in order to combine with one Ca ion in order to form a neutral compound i.e. You need to have the same amount of charges therefore you have two Cl ions which have -1 charges for one +2 Ca ion.
Hope this helps :).
To increase the potential energy of any object, not limited to an apple, you have to hold it higher.
