Answer: 3.33 m/s
Explanation:
Assuming the questions is to convert 12 km/h to meter per second (m/s), let's begin:
In order to make the conversion, we have to know the following:
And:
Keeping this in mind, we can make the conversion:
Then:
If a scientist is studying a model that is a widely accepted theory about the position of planets and sun, the model would most likely help the scientist to understand facts that can't be easily observed. That will make the correct answer to be C.
Answer: 40 J
Explanation: Work is equal to the product of force and distance.
W = Fd
= 4N ( 10 m)
= 40 J
Answer:
The current can be controlled by modifying the resistance value
Explanation:
The current can be controlled by modifying the resistance value, usually a variable resistance device called potentiometer is used. This can be observed mathematically using the ohm law which is defined as voltage equal to the current product by resistance.
V = I*R
where:
I = current [amp]
R = resistance [ohm]
V = voltage [volt]
We can see that if we reduce the resistance the current will be increased
I = v / R
And if we amplify the resistance (R) the current will be diminished
Answer:
KINETIC ENERGY=K.E=0.00245 Joules ≈ 0.003 Joules
Explanation:
mass=m=0.1g=0.0001kg
velocity=v=7.0m/s
kinetic energy=K.E.=?
as we know that
hope it will help ^_^
