Answer: a pattern in nature observed over and over

Explanation:

A scientific law can be define as statement which either describes or predict the natural phenomena. The information given in the scientific law is verified by the experimental procedures and observations which are done under conditions which are tried to mimic the natural system. It can be used to describe the cause of a natural phenomena, duration of natural phenomena  and conditions necessary for the occurrence of natural phenomena and also gives information why and how a natural phenomena repeat itself.

Potential Energy (Before) = Kinetic Energy (After)

mgh = 0.5mv^2

divide both sides by m

gh = 0.5v^2

h = (0.5V^2)/g

h = (0.5*2.2^2)/9.81

Alona [7]

Answer:

Explanation:

This does not violate Newton's 1st law because the net force would still be 0 in order to produce uniform motion (aka constant velocity). The other forces acting on the vehicles is air resistance which is non-zero. So we need car internal force to counter balance this force, which require extra gas for the car.

In a real system of levers, wheels, or pulleys, the AMA is less than the IMA because _____.
grandymaker [24]
In a real system of levers, wheel or pulleys, the AMA (actual mechanical advantage) is less than the IMA (ideal mechanical advantage) because of the presence of friction.

In fact, the IMA and the AMA of a machine are defined as the ratio between the output force (the load) and the input force (the effort):
IMA= \frac{F_{out}}{F_{in}}
however, the difference is that the IMA does not take into account the presence of frictions, while the AMA does. As a result, the output force in the AMA is less than the output force in the IMA (because some energy is dissipated due to friction), and the AMA is less than the IMA.

the headlamp of a car takes a current of 0.4 ampere from a 12 volt supply. the energy produced in 5 minutes is​
serg [7]
Voltage (V) = 12 v
Current (I) = 0.4 A
Time (t) = 5min = 300sec

Power = Voltage x Current
= V x I
= 12 x 0.4
Power = 4.8wats = 4.8W

Power = Energy / Time
Energy = Power x Time
Energy = 4.8 x 300
Energy = 1440 joules
Final answer : 1440J
