8+6.5+2x=52
52/2=8+6.5+x
26=8+6.5+x
26-8-6.5=x
11.5=x
snow shoes.
shoes with large areas in contact with the snoow. reduces the pressure on the snow, and alows you to sink less. or to walk on the surface.
Stilettp high heels would have the opposite effect
Answer:
a = 0.827468
Explanation:
given,
half life of radium-224 = 3.66 days
now,

t is the time
A₀ is the amount at t = 0
at t = 0 , A(0) = 1
A(3.66) = 1/2
at t = 3.66


taking log both side
3.66 log (a) = log (0.5)
log a = -0.0822
now,
a = 0.827468
80 joule is momentarily stored in each spring
<em><u>Solution:</u></em>
Given that,
The coil springs on a car's suspension have a value of k = 64000 N/m
When the car strikes a bump the springs briefly compress by 5.0 cm (.05 m)
By compressing the spring, we apply a force over a distance
As a result we have done work on the spring
Doing work means that we have transferred energy to spring in form of elastic potential
Therefore,
k = 64000 N/m
x = 0.05m
<em><u>The elastic potential energy is given as:</u></em>

Where, "k" is the spring constant and "x" is the displacement

Thus 80 joule is momentarily stored in each spring
