This is the order of the spectrum from highest frequency to lowest frequency:
Gamma Ray (Highest energy em wave)
X Ray (Used in medical imaging)
Ultra violet (dangerous to human skin)
visible light (human eye can see)
Infrared (medium frequency)
Microwave (used to heat food)
Radio (longest wavelength)
Answer:
positive acceleration: releasing an object from a height - acceleration due to the force of gravity, the speed of the object will increase as it falls
negative acceleration: applying breaks on the tires to slow down the car - deceleration due to frictional forces
Answer:
0.1 A
Explanation:
From the question,
V = IR............ Equation 1
Where V = Voltage, I = current, R = Resistance.
Given: I = 0.2 A, R = 10 ohms.
Substitute into equation 1
V = 0.2(10)
V = 2 volt,
If the resistor is replaced with a 20 resistor, The nwe current is
I = V/R................ Equation 2
I = 2/20
I = 0.1 A
