Which two of the following are the densest of the materials shown?Material Mass (g) Volume (L)
Rock 1000 0.5
Pillow 200 10
Bottle of soda 2000 2
Loaf of bread 100 1

Answers

Answer 1
Answer:

Answer:

The densest materials are rock and bottle of soda.

Explanation:

The density of material is given by,

Density = (mass)/(volume)

Case 1: Rock

Density = (1000)/(0.5)

Density = 2000 (g)/(L)

Case 2: Pillow

Density = (200)/(10)

Density = 20 (g)/(L)

Case 3: Bottle of soda

Density = (2000)/(2)

Density = 1000 (g)/(L)

Case 4: Load of bread

Density = (100)/(1)

Density = 100 (g)/(L)

The densest materials are rock and bottle of soda.

Give two ways of reversing the direction of the forces on the coil in the electric motor?​

Answers

Answer:

Interchanging the poles of the magnet

Reversing the direction of the applied current

Explanation:

  1. The working of the electric motor is associated with Fleming's left-hand rule.
  2. It states that if a current-carrying conductor is placed inside a magnetic field, it experiences a force in the direction perpendicular to the direction of the electric current and magnetic field.
  3. These three physical quantities are placed in a mutually perpendicular direction.
  4. So, in order to reverse the direction of force, you have to either change the direction of the current or magnetic field.

The method of heat transfer that plays a central role in transferring heat energy within the atmosphere and the ocean is A. convection. B. radiation. C. conduction. D. reflection.

Answers

Convection is process of transferring heat from one place to the other. Warm air rises that is why heat from water will evaporate and will transfer to cooler atmosphere through this process. In convection, cooler places are replaced by warm air due because cool air sinks and warm air will replace
The answer is A, convection

What is cell division? Like what does it mean? And also if you know, what does it do? Like what's the purpose of it. THANKSSS!!!!!

Answers

Cell division is when one cell splits in half to create two cells. This process is how cells reproduce.
Cells cannot just be created out of nothing. Most cells in living organisms multiply by Mitosis. This process starts with 1 cell and splits into 2 new cells. Firstly, a single cell increases in size. it then replicates and copies everything that is inside it, like DNA. the cell then splits in 2, creating 2 identical new cells.
