Answer:
The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.Jan 4, 2016
Explanation:
Answer:
B
The plastic ball require lesser force than the iron ball
Pressure is the force applied perpendicular to a surface divided by the area of the surface. Therefore, from the given values, we can easily calculate the area by dividing the force to the pressure. We do as follows:
Area = F / P
Area = 15000 / 190000
Area = 0.0789 m^2
Hope this answers the question. Have a nice day.
<span>Sure. Picture this: Your friend is
wearing prescription sunglasses outside. He looks at you through them,
and the light from you is refracted on the way through the glasses, to
correct for his vision. At the same time, if you look at his glasses,
you can see yourself reflected in them. Same light ... from you to his
sunglasses. Part of it passed through the lenses and got refracted.
Another part of the light got reflected back to you, just like hitting a
mirror, and you saw yourself.</span>
Answer:
$531
Explanation:
If the first three months are free, take off 3 from 12. That leaves you with 9. Since you pay $59 every month, 59 x 9 is 531
