Answer:
The experimental apparatus shown in the figure above contains a pendulum consisting of a 0.66 kg ball attached
to a string of length 0.60 m. The pendulum is released from rest at an angle of 60 degrees and collides with a ball of mass 0.22 kg initially at rest at the edge of a table. The 0.22 kg ball hits the floor a distance of 1.4 m from the
edge of the table.
(a) Calculate the speed of the 0.66 kg ball just before the collision.
2.4 m/s
(b) Calculate the speed of the 0.22 kg ball immediately after the collision.
2.8/m s
(c) Calculate the speed of the 0.66 kg ball immediately after the collision.
1.5 m/s
(d) Indicate the direction of motion of the 0.66 kg ball immediately after the collision.
____ To the left __<u>X</u>__ To the right
(e) Calculate the height to which the 0.66 kg ball rises after the collision.
0.11 m
(f) Based on your data, is the collision elastic?
____ Yes __<u>X</u>__ No
Coefficient of elasticity of less than one means an inelastic collision.

It’s not the best written question, but out of the 4 options, the answer is absorption
Answer:
The right answer minimum number of $5 cetificates that each nephews and nieces will get is 2 and maximum number of $5 certificates that each will get is 4.
Explanation:
The minimum number of $5 certificates that each nephews and nieces will get is 2 because he can add $25 + $10 = $35 , he has now capacity of $20 ($55 - $35) in which he can add one more $10 the he must have to add 2 of $5 certificates.
The Maximum number of $5 certificates he can give is 4 because again when he adds every certificate once he has capacity of $20 ( $55 - $25 - $10). He can now add 4 * $5 = $20 so he can get $55.
I was able to find the questions to complete with the verbs saber and conocer:
- ¿<u>Conoces</u> a muchas personas aquí?
- ¿<u>Sabes</u> jugar al tenis?
- ¿<u>Sabes</u> cocinar bien?
- ¿<u>Conoces</u> a los dueños del apartamento?
- ¿<u>Sabes</u> qué tiendas están cerca (close by)?
<u>Saber/conocer</u>
Both verbs (saber and conocer) express the idea of ''knowing". The difference is that you use ''saber'' to talk about facts or learned skills, and you use ''conocer'' when you have familiarity with the thing, person or place you are saying you know.
