Answer:
v1=18.46m/s
v2=29.8cm/s
Explanation:
We know that
the equation of the motion is
we can calculate w by using
Hence, we have that
the speed will be
hope this helps!
Answer:
s (l = 0) only two electrons
p (l = 1) sublevel six (6) electrons fit
d (l = 2) sub-level has 10 electrons
f (l = 3) has 7 has 14 electrons
Explanation:
The electrons have an odd spin, so they must comply with the Pauli principle, therefore only two electrons fit in a given sublevel.
Sub level s (l = 0) only two electrons
Sub level p (l = 1) has three orbitals in which two electrons fit, therefore in the sublevel six (6) electrons fit
Sub-level d (l = 2) has 5 orbitals each with two electrons, the sub-level has 10 electors
Sub-level f (l = 3) has 7 orbitals and two electrons each, the sub-level has 14 electrons
Oil must be mined from underground.
I think you meant friction but false :)
Answer:
The answer is below
Explanation:
a) Impulse is the total effect of force which has been acting on a body over a period of time. Impulse is the product of the force and the period of time applied. It is given by:
Impulse = force × time
Given that during 2 seconds, the impulse is 4 Ns, we can calculate the force applied.
Impulse = force × change in time
4 = force * 2
force = 4 / 2 = 2 N.
Hence the impulse applied during the following 3 seconds is:
Impulse = force × change in time = 2 * (2 + 3) = 2 * 5 = 10 Ns
The impulse applied during the following 3 seconds is 10 Ns not 6 Ns
b) In perfectly elastic collision, there is no loss in kinetic energy while in an inelastic collision there is loss in kinetic energy due to energy conversion or transfer.
In perfectly elastic collision the object does not stick together while in an inelastic collision the object stick together.
