Answer;
A. the distance that the force move
Explanation;
Simple machines function to make work easier by reducing human effort. These machines may increase the strength of the force, or increase the distance over which the force applied or even change the direction in which the force is applied.
Therefore, when these simple machine reduce strength of a force then the distance over which the force is applied or moves should be increased. Examples of machines that makes work easier by increasing the distance over which the force is applied include, hammers and leaf rakes.

Explanation:
The mouse would run faster because it has mass.
Answer:
Darwin’s theory became accepted because it had more evidence that supported it. Lamarck’s theory suggest that all organisms become more complicated over time, and therefore doesn’t account for simple organisms, such as single-cell organisms.

Answer:
Explanation:
Let the velocity of projectile be v and angle of throw be θ.
The projectile takes 5 s to touch the ground during which period it falls vertically by 100 m
considering its vertical displacement
h = - ut +1/2 g t²
100 = - vsinθ x 5 + .5 x 9.8 x 5²
5vsinθ = 222.5
vsinθ = 44.5
It covers 160 horizontally in 5 s
vcosθ x 5 = 160
v cosθ = 32
squaring and adding
v²sin²θ +v² cos²θ = 44.4² + 32²
v² = 1971.36 + 1024
v = 54.73 m /s
A see saw is a class one lever. It moves from one center joint and moves only up or down. As the boy backs up from the middle of the seesaw his mass will weigh him down and lift the girl.
