Answer:
I know that T= kx where T is the tension which equaka the force og gravity = mg = 1.37 * 10 = 13.7 x is the elongation of the spring so the length after dangling the object minus the original length.
I hope it helps
plz let me know if it is wrong or right.
Understanding Newtons second law that everything has an equal and opposite reaction. The reaction force from a balloons air being pushed out is the preasurized air it had to push out into the open air.
Electric field between the plates of parallel plate capacitor is given as

here area of plates of capacitor is given as


also the maximum field strength is given as

now we will plug in all data to find the maximum possible charge on capacitor plates


so the maximum charge that plate will hold will be given by above
Answer:
The heating element of the heater is made up of alloy which has very high resistance so when current flows through the heating element, it becomes too hot and glows red. But the resistance of cord which is usually of copper or aluminum is very low so it does not glow.
The experimenting stage, since the scientist would need to record his or her data on a chart
