What is a difference between newton’s laws of motion and einstein’s theory of relativity?newton’s laws are factual statements, w

hile the theory of relativity is a statement of opinion.newton’s laws can be revised over time, but einstein’s theory of relativity cannot.newton’s laws explain the observations he made, while the theory of relativity was based on one of einstein’s hypotheses.newton’s laws cannot help predict what may happen in the future, but einstein’s theory can.

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

I need help on number 4 and 5
Strike441 [17]

4 is G. BB and Bb because that is what you are analyzing the product of.

5 is C. The round shape is obviously a dominant trait since mixing with a wrinkled shape didn't have an effect. The wrinkled shape is recessive.

Explain why your PE and KE are usually not both high at the same time (If PE is high then usually KE is low)
AfilCa [17]
Might help:

an object can have both kinetic and potential energy at the same time. for example, an object which is falling, but has not reached the ground has kinetic energy because it is moving downwards, and potential energy because it is able to move downwards even further than it already has. as an object falls its potential energy decreases, while its kinetic energy increases. the decrease in potential energy is exactly equal to the increase in kinetic energy.
