It takes Harry 34 s to walk from x1 = -11 m to x2 = -54 m .

miss Akunina [59]

Missing question:
"What is his velocity? Please answer using two sig figs in m/s."

Solution
The relationship between velocity (v), space (S) and time (t) is
 $v= \frac{S}{t}$
The space covered by Harry is
 $S=x_1 - x_2 = -11 m-(-54 m)=43 m$
and so the velocity is
 $v= \frac{43 m}{34 s} =1.26 m/s$

Refer to the image. Calculate the magnitude of change in velocity of the cue ball.

valkas [14]

Answer:

If you add the 2 velocity vectors you get the velocity of the third vector which is the (change in) velocity of the cue ball after striking the cushion

V * 2 * cos 45 = 4 * cos 45 = 2.83 m/s

Hugs 5 things your dog might do when hugged

Nezavi [6.7K]

1. growl: most certainly the dog is going to start growling, but not in a negative, aggressive way, but rather in a surprised, amused way
2. li.ck: the dog will definitely li.ck you, as this is what dogs do when approached
3. pant: dogs pant all the time, especially if it's hot outside, so hugging them makes no difference
4. play: they will want to play with you once they see you love them and want to be around them
5. try to run: some dogs aren't really into hugging, which is why they will try to run away from you because they are confused

Now remember that humans have two eyes that are approximately 7 centimeters apart. Estimate the diffraction limit for human visi

aalyn [17]

Answer:

The diffraction limit for human vision is 2.1 arcseconds.

Explanation:

The diffraction limit of two eyes with a diameter of 7 cm = 0.07 m is equal to:

$Diffraction-limit=2.5x10^{5} *(\frac{600x10^{-9} }{0.07} )=2.1arcs$
