Explanation:
In one day a scientist can travel = 80 km
In 10 days. a scientist can travel = 80* 10
= 800 km.
Work done is when a force is exerted to cause a displacement in a certain object.
the equation for work done ;
work done = force applied * displacement of the object
when the force applied is not in the same direction as that of the displacement of the object then the effect of the force is not its whole value. The force is then applied at an angle to that of the displacement of the object, then the resultant force is the force exerted* cos of the angle between force and displacement, in this instance the angle is 40 °.
the new equation is then;
work done = force cos 40° * displacement
after substitution,
work = 25 N * 0.76 * 50 m
= 957.55 J
round it off
= 9.6 *10² J
the correct answer is B
A mid ocean ridge is a under water mountain range, knowing this what would you say it is most similar to on land? hope this helped!
Using Newton's Second Law, we can find the air resistance. We know the net force is equal to mass times acceleration.
