Concept being tested: Waves and types of waves
To answer the question we need to define both electromagnetic waves and mechanical waves.
- Waves can be classified as either electromagnetic waves and mechanical waves based on whether they require a material medium for transmission or not.
- Electromagnetic waves do not require a material medium for transmission and can travel through a vacuum.
- Mechanical waves, on the other hand, are waves that require a material medium for transmission.
What are examples of electromagnetic waves and mechanical waves?
- Examples of electromagnetic waves include gamma rays, radio waves, visible light, etc.
- Examples of mechanical waves include sound waves and water waves.
Therefore, the answer to our question is;
- Electromagnetic waves are not mechanical waves, which means they can travel in a vacuum.

Answer:
C
Explanation:
Static electricity is what makes your hair stand up when you rub a balloon against it or gives you a shock from your doorknob. In static electricity, electrons are moved around mechanically (i.e. by someone rubbing two things together).
HOPE THIS HELPED AND LETTER D MADE ME LAUGH
Answer:
585lb
Explanation:
Given the following
F1 = 235lb
F2 = 350lb
The resultant is expressed as;
FR = F1+F2
Substitute the given values
FR = 235+350
FR = 585lb
Hence the magnitude of the resultant is 585lb
