Answer:
<h2> The refracted angle is r= 34.47°</h2>
Explanation:
According to snell's law the incident normal and refracted ray at the point of incidence all lie in the same plane
Given
incident angle i= 60°
refracted angle r= ?
index of refraction u= 1.53.
Applying the formula
solving for r
r= 34.47°
Answer:
1.82°C
Explanation:
presumir inicial comprimento = l₀ = 5 m
dado que:
coeficiente de expansão (α) = 22 x 10⁻⁶, A variação no comprimento (ΔL) = 0.0002 m,
inicial comprimento = l₀ = 5 m
variação na temperatura = ΔT
para Calcular a variação na temperatura, nós usamos a fórmula:
substituindo valores:
variação na temperatura = 1.82°C
Answer:
Explanation:
The quantity of oxygen in the atmosphere influences the development trajectory, cardiovascular allometry, and metabolic rate of the American alligator. The growth of hypoxic alligators is hampered by a lack of oxygen in the atmosphere, which may impair their food use capabilities.
Answer:
Explanation: The term "midnight sun" refers to the consecutive 24-hour periods of sunlight experienced in the north of the Arctic Circle and south of the Antarctic Circle. Other phenomena are sometimes referred to as "midnight sun", but they are caused by time zones and the observance of daylight saving time.
Complete question is;
Which action would increase the strength of the electric force between the balloon and the water?
A. Holding a magnet near the stream of water
B. Holding the balloon closer to the stream of water
C. Holding a magnet near the balloon
D. Moving the balloon farther away from the stream of water
Answer:
B. Holding the balloon closer to the stream of water
Explanation:
When we take a charged balloon near water, what happens is that it makes electrons to be pushed away which in turn leaves the area to be positively charged. This area is now attracted to the balloon and thus the strength of the electric force between the balloon and the water is increased.
