Answer:
693.685 N
Explanation:
t = Time taken
u = Initial velocity = 27 m/s
v = Final velocity
s = Displacement = 578 m
a = Acceleration
m = Mass
Equation of motion
Force
F = ma
Magnitude of braking force required to stop the car is 693.685 N
Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive. Stars start their lives as clouds of dust and gas.
Answer:
This relationship is explained by Ohm's law
Explanation:
Ohm's law states that the current flowing through a circuit or a resistor is directly proportional to the voltage across the resistor and inversely proportional to the resistance. Where current is i, voltage is v and resistance is r, Ohm's law can be represented mathematically as
V= IR
