Answer:
Therefore, the temperature at which the Fahrenheit scale reading is equal to half of the Celsius scale is −24.6∘C .
Answer:
r = 0.664 m.
Explanation:
Let's write the equation of the magnetic force, the blacks syndicate vectors
F = q v x B
From this expression we see that the force is perpendicular to the velocity and the field, so it is a centripetal force, the modulus of the force is
F = q v B sinT
We write Newton's second law
F = m a
a = v² / r
q v B sinT = m v² / r
r = m v / (q B sinT)
Let's calculate
r = 9.1 10-31 2.9 107 / (1.6 10-19 1.7 10-3 sin8.4)
r = 26.4 10-24 / 0.3973 10-22
r = 0.664 m
This is the distance from where the electron penetrates
The Earth's natural climate cycle
Over the last 800,000 years, there have been natural cycles in the Earth's climate. There have been ice ages and warmer interglacial periods. After the last ice age 20,000 years ago, average global temperature rose by about 3°C to 8°C, over a period of about 10,000 years.
For lenses, light converges to a point for a convex lens. A convex mirror diverges light.

The lens is transparent throughout (lets light pass through), while the mirror reflects light.
