Explanation:
Answer:
420.17 nm
Explanation:
Given:
f = 7.14 × 10¹⁴Hz
c = 3 × 10⁸ m/s
c = fλ
λ = c/f
= 420.17 nm
B. ice age.
C. cold wave.
D. draft.
Answer:
Is the sum of a vector of two or more vectors.
Current = 4 amps
Resistance =
Explanation:
Given that,
Voltage, V = 220 V
Current, I = 4 A
We have to find the resistance of the appliance.
Ohm's law gives the relation between the current, resistance and the voltage.
V = I R, R = resistance
So,
Resistance of the appliance is .
Hence, this is the required solution.
Answer: Milankovitch cycle
Explanation: Every 100,000 years, the Earth's orbit becomes more elongated. this change in orbit has caused past ice ages and is called a Milankovitch cycle.
According to Milutin Milankovitch, the Milankovitch cycle explains the effect of the change in the earth's climate over thousands of year.
