Answer:
U = 1794.005 × 10⁶ J
Explanation:
Data provided;
Capacitance of the original capacitor, C = 1.27 F
Potential difference applied to the original capacitor, V = 59.9 kV
= 59.9 × 10³ V
Now,
The Potential energy (U) for the capacitor is calculated as:
Potential energy of the original capacitor, U = × C × V²
on substituting the respective values, we get
U = × 1.27 × ( 59.9 × 10³ )²
or
U = 1794.005 × 10⁶ J
Answer:
Savannas have a fairly constant temperature all year; temperate grasslands have a greater seasonal temperature variation.
Explanation:
For example, the African Savanna has an almost constant temperature all year (see the first figure below).
The difference between summer and winter temperatures is only about 5 °C, and the rate of temperature change is quite slow.
The temperature of a temperate grassland (see the second figure below) has a much greater seasonal variation.
The summers are hot, and the winters are cold. The difference between summer and winter temperatures is about 30 °C, with a rapid rate of temperature change from one season to the next.
