Hammer and screwdriver perform different tasks because they are both simple machines.
A machine is simply a device that can be used to perform a task. This machine can be any physical system or device designed to perform a specific task.
The efficiency of the machine describes the easy with which each machine or tool is able to use input power to overcome a task.
Machines are designed to overcome a particular task with little effort in order to increase its efficiency.
Hammer and screwdriver, are both examples of simple machines.
Thus, Hammer and screwdriver perform different tasks because they are both simple machines.

<span>Since the force is applied at an angle from the
horizontal, we will use the horizontal component of this force in calculating
for the displacements.
From derivation, the Fx is:</span>
Fx = F cos φ
Where:
Fx = is the horizontal component of the force
F = total force
φ =
angle in radian = 37 * pi / 180 = 0.645 rad
Calculating: Fx = 30.0 N * cos(0.645)
Fx = 23.97 N = 24 N
Calculating for Work: W = Fx * d
A. W = 24 N * 15 m = 360 N
B. W = 24 N * 16 m = 384 N
C. W = 24 N * 12 m = 288 N
D. W = 24 N * 14 m = 336 N
Answer:
You should have noticed that the number of atoms in the reactants is the same as the number of atoms in the product. The number of atoms is conserved during the reaction. However, you will also see that the number of molecules in the reactants and products are not the same.
Earth's land and ocean surface to the atmosphere.
Answer:
19.62 ms
Explanation:
t = Time taken = 2 s
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s² (downward direction is taken as positive)
Equation of motion
The speed of the pebble when it hit the water is 19.62 ms
