\dfrac{1500}{3.28}=457 metres.

Since he was at 1450 m, he thought he was above the correct altitude by

URGENT I WILL GIVE BRAINLIEST
Reil [10]

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

W = mg

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

W = (140 kg)(9.8 m/s^2)

W = 1372 N

so correct answer will be

<em>D. 1372 N</em>
