Answer:
it decrease by 9 times
Explanation:
If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).
Answer:
They are not conductors of heat.
Explanation:
Metals, like steel, are good conductors because of the particles they are made of. Materials like rubber are good insulators, because they don't pick up heat easily. Vacuums(not vacuum cleaners, matter-less voids) are good insulators.
Answer:
hermal energy is the energy that is generated and measured by heat.
They are called mechanical waves
Answer:
the impedance of the circuit is 25.7 ohms.
Explanation:
It is given that,
Voltage, V = 50 volts
Frequency, f = 60 Hz
Resistance, R = 25 ohms
Capacitive resistance, 
Inductive resistance, 
We need to find the impedance of the circuit. It is given by :
Z = 25.7 ohms
So, the impedance of the circuit is 25.7 ohms. Hence, this is the required solution.
