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.

Which statement best describes the relationship between mass and gravitational attraction (pull)?
Gnesinka [82]

Answer:

The first option, "The more mass an object has, the greater the gravitational pull. "

Explanation:

Newton's Law of Gravity states that F_G=\frac{Gm_1m_2}{r^{2}}, where G is the gravitational constant, m_1 and m_2 are the masses of the two objects, and <em>r</em> is the distance between the objects' centers. Because the objects' masses are in the fraction's numerator, they are directly proportional to F_G, and increasing the mass of one or both objects increases the gravitational pull.

Please have a great day! I hope this helps you understand the question!

Color is a result of the absorption and reflection of light. A shirt appears a color because it reflects that color of light. A
Damm [24]

The clothing seems white because the entire light is reflected.

<h2>what is absorption and reflection?</h2><h3>Absorption:</h3>

This occurs when light is transformed into another type of energy. This happens when light vanishes while travelling through another medium.

<h3>reflection:</h3>

It is referred to as light reflection when a light ray hits a polished, smooth surface and bounces back. The incident light rays hit the surface and are reflected off of it. The beam that returns is referred to as the reflected ray.

Three hunters x,y and z aim at a bird on top of a tree.Their individual probabilities of killing the bird are 3/5,2/3 and 5/6 re
TiliK225 [7]

Answer:

1   3/5*2/3=6/15

2   (3/5*2/3)+(2/3*5/6)+(3/5*5/6)=Ans

3  same as 2 i think

4  3/5+2/3+5/6=ans

5 (1-3/5)*(1-2/3)*(1-5/6)

Explanation

1 means x and y... for such a  we multiply the probabilities

2 means x and y or x and z or y and z9 multiply ands  add ors

3 i think it is same as 2

4 for this you have to negate the probabilities of killing to find that of not killing.   Since it will be x and y and z, you multiply the final probabilities

A force of 100 N acts upward. Resolve this force into 2 components; one that acts 30º north of west and one that acts 60º north
GrogVix [38]

To resolve these forces we have to make use of the sines and cosines.

To resolve this force in 30 degree north of west, the answer will be

100*sin(30)

The answer will be 50N

Now to resolve the force acting 60 degree north of east

100* cos(60)

The answer will be 50N.

This also adds to the total force acting that is 50+50=100N. This is the way forces are resolved according to their specified angles.
