I think the correct answer from the choices listed above is option C. The formula that would represent the speed of the Toyota would be <span>T+10 mph= 60 mph. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
Answer:
A beat with the frequency of 10Hz.
Explanation:
The frequencies from the tuning fork and guitar will cancel each other.
The frequency of tuning fork = 340Hz
The frequency of guitar string= 350Hz
The offset = 350Hz - 340Hz = 10Hz
A 10Hz frequency sound is still heard.
Answer:
no deflection
Explanation:
current is flowing from west to east. As the magnetic field of a long wire carrying current is circular, its direction will be north below the wire and south above the wire (according to the right hand rule). So, when the compass is placed underneath the wire, it will still point towards the north direction.
Answer :
New force becomes, F' = 1.83 N
Explanation:
Let two point charges exert a force of 7.35 N force on each other. The electric force between two charges is given by :
are charges
r is the distance between charges if the distance between them is increased by a factor of 2, r' = 2r
New force is given by :
F' = 1.83 N
So, the new force between charges will be 1.83 N. Therefore, this is the required solution.
