D. 289
Take the formula:
K=5/9(Fahrenheit-32)+273
Plug in Fahrenheit
K=5/9 (60-32)+273
From here it is simple math and you can plug it into your calculator getting 288.5555556 and round to 289
Weight : It is the gravitational attraction force on an object near its surface.
It is always measured in the unit of Newton(N)
it is given by the product of mass and acceleration due to gravity

here we know that mass of the pig is m = 140 kg
also we know that acceleration due to gravity near the surface of earth is approximately g = 9.8 m/s/s
so here we know by above formula


so correct answer will be
<em>D. 1372 N</em>
Answer:
The work done by the frictional force is 600J.
Explanation:
The work
done by the frictional force is
.
Now,
and
; therefore,


Hence, the work done by friction is 660J.
Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass.
Answer:
2,8
Explanation:
The first electron shell would have 2 electrons, the second shell would have 8 electrons. This is because Neon has a relative charge of 10.
