When a star collapses to form a black hole, its mass _____.a. decreases b. remains the same c. increases
Answers
When a star collapses to form a black hole,its mass increases, that is letter C. One example of this is the Big BangTheory. It is by no doubt that our universe had had its ownstarting point but how it really started became a debate for the scientistsover the past centuries. From theories such as Ekpyrotic theory, White Holes,Matrix theory, and Quantum theory, the Big Bang theory is the theory mostlyaccepted by scientists. According to the theory, the universe started as asingularity, that is, from a black hole under extreme gravitational pressureand expanded (instead of exploded) and cooled. Its cooling, according to thetheory, is still happening now as of the moment.
A 2 kg wagon is at rest on a sidewalk. How much gravitational force is acting on the wagon?
Answers
F = ma m = 2 a = g = 9.81 (since it is gravitational force we use 9.81 m/s^2)
F = 2(9.81) = 19.62N
The answer is 19.62N!
What’s the efficiency of a car that uses 400,000 J of energy from gasoline to make 48,000 J of kineticenergy?
Answers
To calculate efficiency you should divide output by input energy.
The engine produces 48000 j energy from 400000 j given energy from gasoline.
48 000/400 000 = 48/400 = 12/100 = 12%
Efficiency of this engine is 12%
