Hello!

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

Simple machines have few or no moving parts. They make work easier.

  1. Inclined plane
  2. Wedge
  3. Screw
  4. Lever
  5. Wheel and axle
  6. Pulley

Inclined plane is a sloping surface, such as a ramp. Inclined plane make it easier to lift objects. The distance is greater, but the amount of force used is less. The amount of work done is the same. Wedge is used to split things apart. Force is applied to the large area of the wedge. The force is concentrated on a smaller area at the pointed end. The wedge looks like two inclined planes placed back to back. A screw can hold things together. The threading grips materials. The threading on a screw looks like an inclined plane spiraling around the outside of the screw. Large screw are also used to lift things. A car jack lifts a car by using a large screw. A lever is a strong bar that turns about a fulcrum, or fixed point. It can be used to lift heavy objects. Force applied at one end is transmitted to the other end. A lever can change the direction of a force. Moving the position of the fulcrum affects how much force is needed. A wheel and axle consists of two circular objects of different sizes that are connected. The smaller-diameter object, the axle, is a rod that goes through the wheel and lets the wheel turn. When the axle is turned, the wheel moves a greater distance, but less force is needed to move it. A pulley changes the direction of a force. A pulley consists of a grooved wheel and a rope. Pulling down on the rope lifts objects. A construction crane uses a series of pulleys. A flagpole has a pulley at the top.

Hope this helps!

What is the relationship between the masses of the objects and the gravitational force between them
irga5000 [103]

The relationship between the masses of the object and the gravitational force between them is a direct relationship

Explanation:

The gravitational force between two objects is given by  the equation:

F=G\frac{m_1 m_2}{r^2}

where

G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2} is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

We observe that:

- The gravitational force is proportional to the masses of the two objects, m1 and m2, so if the masses increase, the force will increase as well (so, this is a direct relationship)

- The gravitational force is inversely proportional to the square of the separation between the objects, so if the distance is increased, the force will decrease (so, this is an inverse relationship)

Answer:

See below ~

Explanation:

An object will sink in water when its density is greater than that of water, which is 1 g/cm³.

Volume of the box is <u>1331 cm³</u>. (11³)

Maximum mass of sand will be 1331 g. [because 1331/1331 = 1 g/cm³]

  • Volume of sand = Mass of sand / Density of sand
  • Volume (sand) = 1331/3.5
  • Volume (sand) = 380.29 cm³

If the volume of sand is <u>greater than 380.29 cm³</u>, the box will sink in water.
