Answer:

Vf = 60 [m/s]

Explanation:

To solve this problem we must use the following equation of kinematics.

$v_{f}= v_{i}+(a*t)$

where:

Vf = final velocity [m/s]

Vi = initial velocity = 0

a = acceleration = 1 [m/s^2]

t = time = 60 [m]

Now replacing:

Vf = 0 + (1*60)

Vf = 60 [m/s]

Why can we hear sound around a corner but not see light

Viktor [21]

Answer:

Sound waves that we can hear have much longer wavelengths than do light waves. As a result, the diffraction of sound waves around a corner is noticeable and we can hear the sound in the “shadow region,” but the diffraction of light waves around a corner is not noticeable.

50 POINTS! Chipping from the rough, a golfer sends the ball at an angle of 54° with an initial velocity of 13m/s, how far down t

docker41 [41]

Range equation:

$x=\dfrac{{v_i}^2\sin2\theta}g$

This ball travels a distance of

$x=\dfrac{\left(13\frac{\rm m}{\rm s}\right)^2\sin108^\circ}{9.8\frac{\rm m}{\mathrm s^2}}=16\,\mathrm m$

How long was a 50 W lightbulb left on for if 500,002 J were burned?

saveliy_v [14]

" 50 W " means " 50 Watts " or " 50 Joules per second ".

(500,002 J) / (50 J/sec) = <em>10,000.04 seconds</em>

(That's 2 hours 46 minutes 40.04 seconds.)

The closure temperature represents the point when ________. A. a magma cools to the point where minerals begin to crystallize B.

melomori [17]

The closure temperature represents the point when isotopes are no longer free to move out of a crystal lattice.

Answer: Option C

<u>Explanation:</u>

The closure temperature can also be termed as blocking temperature. It is mostly used in radiometric dating. As the temperature decreases, below a certain point the isotopes may get freeze in their lattice positions. And there may be slowing of diffusion.

At the closure temperature, that rate of diffusion will be zero as the isotopes will be no longer free to move out of crystal lattice. So, this is termed as closure or blocking temperature. As the isotopes loose their ability to move, their concentration will remain fixed in their position leading to measurement of radiation dating.
