Answer:
Explanation:
Sun - - - - - Earth----Capital building----Human----Atom
The sun would exert more gravitational force because it is the massive.
Gravitational force is directly proportional to mass.
12.0 min = 720. s
so the distance covered moving at a constant 15.0 m/s is
(15.0 m/s) (720. s) = 10,800 m = 10.8 km = 1.08 × 10¹ km
Answer:
the correct answer is A
Explanation:
In an electrical circuit the switch can be of two types: unipolar and bipolar.
The bipolar switch refers to a three-contact switch that allows the polarity in the circuit to be reversed.
The unipolar switch has only two contacts so the polarity of the circuit is in one direction and the switch serves to interrupt the passage of electrons in the circuit.
Consequently the correct answer is A
The kinetic energy is proportional to the square of the speed, so doubling the speed increases the kinetic energy by a factor of 4.
