A 0.111 kg hockey puck moving at 55 m/s is caught by a 80 kg goalie at rest. With what speed does the goalie slide on the (frict

Andrews [41]

Answer: 0.076 m/s

Explanation:

Momentum is conserved:

m v = (m + M) V

(0.111 kg) (55 m/s) = (0.111 kg + 80. kg) V

V = 0.076 m/s

After catching the puck, the goalie slides at 0.076 m/s.

Air is warmed and moisten as it moves through both the mouth and nasal passages.

Alexxx [7]

Well, in my own personal case, I can actually move the air in either
direction through both of those.

When I move the air inward from the outside, it's warmed and moistened.

When I move it outward from the inside, it's not.

The eyepiece of a compound telescope has a focal length of 12 cm and the objective lens has a focal length of 16 m. What is the

olasank [31]

Answer:

The magnification is 133X

Explanation:

For a refractor telescope using convex lenses, the overall magnification os calculated as by dividing the focal length of the objective by that of the eyepiece.

$M = \frac{f(obj)}{f(eye)}$

So:

$M = \frac{16 m}{12 cm}$

Care must be taken with the units, in this case they are in meters and centimeters, they should be converted into the same unit before calculating:

$M = \frac{16 m}{0.12 m} = 133$
