Answer:
The balloon will collapse
Explanation:
When air is removed from the bell jar, the balloon will collapse if the internal pressure from the balloon does not balance the atmospheric pressure from the surroundings.
Radiation can carry thermal energy.
Answer:
a. 17 μC b. 14.45 J
Explanation:
Here is the complete question
A pair of 10μF capacitors in a high-power laser are charged to 1.7 kV.
a. What charge is stored in each capacitor?
b. How much energy is stored in each capacitor?
a. The charge Q stored in a capacitor is Q = CV where C = capacitance and V = voltage. Here, C = 10μF = 10 × 10⁻⁶ F and V = 1.7 kV = 1.7 × 10³ V.
So, Q = CV = 10 × 10⁻⁶ × 1.7 × 10³ = 1.7 × 10⁻² C = 17 × 10⁻³ C = 17 μC
b. The energy stored in a capacitor is given by W = 1/2CV² = 1/2 × 10 × 10⁻⁶ F × (1.7 × 10³ V)² = 1/2 × 10 × 10⁻⁶ F × 2.89 × 10⁶ V² = 1/2 × 10 × 2.89 × 10⁶ × 10⁻⁶ J = 14.45 J
To obtain a delay of 360 ms for a clock with frequency of 48 khz, we must set the constant in the button debounce circuit's stretch timer to the value of 1720.
Set the comparator value of the debounce circuit's stretch timer to have a delay of one second to examine the impact of the pulse stretch timer. To do this, set the stretch compare megafunction's constant value to 4800
For 1 second = 48000
For 360 ms =
× 360 × 
= 17280
Some pupils struggle with the concept of switch bounce. They are never less than amazed when we use the oscilloscope to view a switch's output. Depending on the situation, I utilize either hardware or software for the debounce solution. A capacitor and resistor are frequently inexpensive in terms of price and board area, thus I typically choose a hardware solution to free up my inexpensive microcontroller to perform other crucial tasks.
