3: A Erosion is the action and movement of a surface process
Answer:
Newton's third law of motion.
Explanation:
Every action has an equal and opposite reaction.
Answer:
d = 84 m
Explanation:
As we know that when an object moves with uniform acceleration or deceleration then we can use equation of kinematics to find the distance moved by the object
here we know that
initial speed
final speed
time taken by the car to stop
now the distance moved by the car before it stop is given as
now we have
To solve this problem we will use the concepts related to Ohm's law for which voltage, intensity and resistance are related.
Mathematically this relationship is given as
Where,
V= Voltage
I = Current
R = Resistance
The value of the given voltage is 12V, while the current is 12mA, therefore the resistance would be
Therefore the resistance is
