I believe it is an electromagnet
Based on the options given, the answer is two waves subtract from each other. Destructive interference happens when two waves meet each other however with different frequencies cancel each other out.

Answer:Friction is a force that opposes the motion of objects; friction can cause objects to slow down. Air resistance is a type of friction. Air resistance causes moving objects to slow down. Different physical properties, such as the shape of an object, affect the air resistance on an object.
Explanation:
Answer: The acceleration of an object will decrease
Explanation: This happens as if the mass of an object increases then the acceleration of the body decreases as acceleartion is directly proportional to the mass of the body by Newton's 2nd law F=MA we can say the more mass an object has the more net force needs to be applied to make it start accelerating
Answer:A
Explanation:
Electric force intensity=electric charge x electric field intensity
From the formula it shows that electric force intensity is directly related to electric charge
