B. Frequency divided by wavelength
Answer:
Explanation:
a) According to ohm's law
V = IR
V is the supply voltage
R is the resistance
I is the current
Given Resistance = 200ohms
Voltage = 20V
I = V/R
I = 20/200
I = 0.1Amperes
b) Using the ohm's law formula
V= IR
Where voltage = 12volts
Current I = 3A
Resistance R = V/I
R = 12/3
R = 4ohms
c) Power generated by the battery is expressed as P = IV
I = P/V
Given Power = 2Watts
V = 1.5volts
I = 2/1.5
I = 1.33A
d) similarly, power = current I × voltage V
V = P/I
Given P = 90watts
I = 4.5A
V = 90/4.5
V = 20volts
e) Given power = 1.5kW = 1500watts
Voltage = 300volts
I = P/V
I = 1500/300
I = 5A
Answer:
the impact on the water varies from different heights, therefore the mass stays the same, yet the force on the water increases from a higher height. A taller height will produce a bigger splash!
Explanation:
Answer: (-4.3, 2.5)
Explanation:
In the second quadrant, magnitude of the vector is 5 and angle is 30° from the negative x-axis.
We can write this in terms of its components:
Thus, the components of vector in the second quadrant are (-4.3, 2.5)
That’s kinda messed up ⬆️
