Answer:
<h2>1.4 m/s</h2>
Explanation:
The velocity can be found by using the formula
k is the kinetic energy
m is the mass
From the question we have
We have the final answer as
<h3>1.4 m/s</h3>
Hope this helps you
Answer:
Explanation:
Speed of car =22.5miles/hr
U=22.5miles/hour
Applied brake and come to rest
Final velocity, =0
t, =2sec
Given that,
Speed=distance /time
Then,
Distance, =speed, ×time
Converting mile/hour to m/s
Given that
Use: 1 mile= 1600 m, 1 h= 3600s
22.5miles/hour × 1600m/mile × 1hour/3600s
Therefore, 22.5mile/hour=10m/s
Using speed =10m/s
Distance =speed ×time
Distance=10×2
Distance, =20m
The distance travelled before coming to rest is 20m.
Radiation can pass through any phase of matter.
Examples:
Light, radio, heat, and X-rays, all pass through glass (solid),
water (liquid), and air (gas) very easily.
(Moreover, I would be remiss if I failed to point out in addition that
microwave radiation passes through meatloaf and coffee with only
partial attenuation due to absorption.)
The answer is D. discrimination.<span />
