How are electromagnetic waves different from sound or water waves?
Annette [7]

Explanation:

Electromagnetic waves are different from sound or water waves in such a way that water and sound waves are called mechanical waves that requires a material medium for their propagation.

Electromagnetic waves do no require a material medium for propagation.

  • Electromagnetic waves are carried or transported by radiation and this can be passed through vacuums and different other materials.
  • But mechanical waves such as water and sound waves requires a material medium for their propagation.
  • They cannot pass through a vacuum.

A car has<br> weight of 10,ooow<br> What is the mass of the car<br> on earth (g=10N/KG)
Gre4nikov [31]

Answer:

1000 kg

Explanation:

We know the formula for finding out weight is W=mg

W= 10,000 N

M=?

g=10 N/KG

W=mg

10,000=10m

m=1000kg

Scott drives a jeep 12 km east, then 4 km north, then finally 3 km west. He traveled a total distance of:​
horsena [70]

Answer:

Using the pythagoras theorem

S²=9²+4²

S²=81+16

S²=97

S=9.85km.

In finding the direction

tan□=opposite/Adjacent

=4/9

□=23.96

¤=90-23.96

=66.03 degrees

9.85, N 66.03 E

Choose the sequence of energy forms that best fits each item.
levacccp [35]

Answer:

1. chemical energy --> electrical energy --> light energy

2. Electrical Energy --> Mechanical Energy

3. Electrical Energy --> Heat Energy

4. Chemical Energy --> Thermal Energy  --> Mechanical Energy

5. Nuclear Energy --> Light energy and thermal energy

6. Mechanical Energy --> Electric Energy

7. Chemical Energy --> Electrical Energy --> Sound Energy

8. Mechanical Energy --> Sound Energy

Explanation:

1.<u>FLASHLIGHT</u>:

chemical energy --> electrical energy --> light energy

The chemical energy from the cell batteries is converted to electrical energy, which is used to produce the light energy in form of flashlight.

2.<u>ELECTRIC SAW</u>:

Electrical Energy --> Mechanical Energy

The electrical energy from the socket is converted to the mechanical energy used to run the saw blade.

3.<u>TOASTER</u>:

Electrical Energy --> Heat Energy

The electrical energy from the socket is converted to the heat energy (thermal energy) used in browning the bread.

4.<u>GAS POWERED SCOOTER</u>:

Chemical Energy --> Thermal Energy  --> Mechanical Energy

The chemical energy from fuel, such as petrol is converted to heat (thermal energy) in the engine by the process of combustion. This heat is then used to do work by conversion into mechanical energy, through piston movement, which in turn moves the shaft and the scooter.

5.<u>THE SUN</u>:

Nuclear Energy --> Light energy and thermal energy

The nuclear reactions on Sun provide nuclear energy which is converted into light and thermal energy that reaches us on earth.

6.<u>WIND TURBINE</u>:

Mechanical Energy --> Electric Energy

The mechanical energy is provided by wind when it rotates the blade of turbine. This is then converted to electrical energy b the turbine.

7.<u>IPOD</u>:

Chemical Energy --> Electrical Energy --> Sound Energy

The chemical energy i supplied by the battery of ipod, which is converted to electrical energy and that electrical energy is used to produce sound by ipod.

8.<u>SPEAKER VIBRATES</u>

Mechanical Energy --> Sound Energy

The mechanical energy due to vibration produces sound energy.
