She can monitor her practice run times to see if they are decreasing.
Answer:
The correct answer is - 43%.
Explanation: The increase in CO2 between these two suggested periods is approximately 43%. Even though it is a natural process that the CO2 levels vary in the atmosphere, still this is not the same case nowadays. Nowadays, or rather in the past few decades, apart from the natural increase of CO2 in the atmosphere, it has seen a much more increased levels because of the human activity. The industrial facilities and the vehicles, the cutting of the forests and burning the wood (there's both release of CO2 from the burning of the trees and loss of natural accumulator of the CO2), are just some of the more important human activities that contribute to a significant rise in the CO2 levels.
Newton's first law of motion - sometimes referred to as the law of inertia. Newton's first law of motion is often stated as. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Answer:
Explanation:
given,
Power source = 5 V
R₁ = 25 Ω
R₂ = 50 Ω
a) when they are arranged in series
R = R₁ + R₂
R = 25 + 50
R = 75 Ω
b) current = I = 
I = 
I = 0.067 A
so, the resistors are connected in series hence current in both the resistor will be 0.067 A.
c) when they are arranged in parallel
R = 16.67 Ω
d) current through the battery 
= 0.3 A
current through 25 Ω resistor = 
current through 50 Ω resistor =
