I think by radio I'm just guessing on what seem more sence
Answer:
Kingdom Plantae
Explanation:
Plants are multi-celled, have roots, and are found in the backyard. I also did research but I can't put it in here or else my answer gets deleted. :)
Answer: C) 0.25 m
Explanation: In order to explain this problem we have to consider the Faraday law, we have:
ε=-dФ/dt where ε the emf induced by the change of the magnetic field given by dФ/dt.
then ε=I*R=17*6=102 V
We have a coil then we have the magnetic flux as follow:
Ф=N*A*B then we have
dФ/dt= N*A*dB/dt where A and N is the area and number of turn of the coil.
A=π*R^2 where R is the radius of teh coil.
Finally we have;
dФ/dt= N*π*R^2*dB/dt then
R= [dФ/dt/(N*π*dB/dt)]^1/2= [102/(180*π*3)]1/2=245.2*10^-3=≅0.25m
Explanation:
The potential energy is stronger at the start of the bounce and when it is near the end bounce the balls accelerated rate will be lower because the force has decreased . Also I love your profile picture miraculous rocks !
