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>
It depends on the mass of the moving object versus the mass of the stationary object. if the mass of the moving object is larger the stationary object will get sent into motion. if the mass of the stationary object is larger than the moving object, the stationary object will stay stationary and cause the moving object to do the same. if the two objects have the same mass, they will likely move together upon impact and then eventually come to rest.
Answer:
geothermal energy
Explanation:
the energy is obtained from the heat within the surface of earth
The properties of acids are: (A), (C) and (D).
Explanation:
Acids taste sour, and most
acids are poisonous. Furthermore, acids react with certain metals to
produce hydrogen gas. Few acids are corrosive as well. The option (B) is not valid because acids react with BASES (not with other acids) to produce salt and water. Hence A, C and D are the correct options.
