It is vital to take measurements at the same time everyday to determine the natural cycle, this will show the numbers on a regular basis. It is important because this will be basis of any action that needs to be taken. If it's not taken at the same time, it may disrupt the correct result or change the expected outcome.
Answer:
prevents pollution, reduces the need to harvest new raw materials, saves energy, reduce greenhouse gas
Answer: "For a projectile with no air resistance, at the peak of its path, it's velocity is equal to zero"
Explanation:
Suppose that you throw an object up. The initial vertical velocity will be positive, and the acceleration (the gravitational acceleration) will point downwards, meaning that it opposes to the initial direction of the velocity, and that decreases the velocity as the time goes by.
There will be a point where the velocity ( that was positive until now, so until now the height of the object was increasing), is equal to zero, this means that at this moment the object stops moving, and after, because we still have negative acceleration, the velocity will start become negative, and the object will fall down.
Then that point where the velocity was zero is the peak of its path, then we can conclude that:
"For a projectile with no air resistance, at the peak of its path, it's velocity is equal to zero"
Answer:
The voltage will be 0.0125V

Answer:
The magnitude of the induced emf is
Ф = 5.419 x 10⁻³ V
Explanation:
Given:
r = 23.0 cm = 0.23 m
β₁ = 0.50 T
β₂ = 2.50 * 0.50 T = 1.25 T
Calculate the magnitude of the induced emf the magnetic field is increasing
Ф = A * Δβ / Δt
A = π * r² = π * 0.23² m = 0.166 m²
Ф = 0.166m² * (1.25 - 0.5) T / 23 s
Ф = 5.419 x 10⁻³ V
