Amy has a mass of 30 kg, and she is riding a skateboard traveling 5 m/s. What is her momentum?

Flauer [41]

Hey there!

So we know that m*v=P.
And in this question m=30
v=5 m/s
P = 30*5 Kgm/s
P = 150 Kgm/s

So, your final answer is 150 Kg.m/s

Hope this helps! :)

A ball is thrown horizontally from the top of a building 22.3 m high. The ball strikes the ground at a point 127 m from the base

DochEvi [55]

Answer:

t = 2.13 s

Explanation:

given,

height of the building = 22.3 m

horizontal distance = 127 m

acceleration due to gravity = 9.8 m/s²

time for which ball is in motion = ?

using equation of motion

$s = u t + \dfrac{1}{2}gt^2$

initial velocity is zero

$s = \dfrac{1}{2}gt^2$

$t = \sqrt{\dfrac{2s}{g}}$

$t = \sqrt{\dfrac{2\times 22.3}{9.8}}$

t = √4.551

t = 2.13 s

The quantum state of a particle can be specified by giving a complete set of quantum numbers (n,l, ml, ms). How many different q

Delvig [45]

Answer:

number of quantum states = 8

Explanation:

To find the total number of allowed states you take into account the following relations:

$l=n-1\\\\m_l=-l,-(l-1),...,0,,,,(l-1),l$

in this case you have:

$n=2\\\\l=0,1\\\\m_0=0\\\\m_1=-1,0,1$

furthermore, for each n,l,ml quantum state you have two additional states due to the spin of the electrons.

then, you have (n,l,ml) = (2,0,0), (2,1,-1), (2,1,0), (2,1,1) and with the spin:

number of quantum states = 2*(1+3) = 8
