Answer:
3 significant figures
Explanation:
here zero is counted as one of the significant figures since it lies next to an integer.
hence the number has 3 sfg
Answer:
if i'm not mistaken that's either a plug in cord for a certain device, or what i am assuming to be a usb software cord.
Explanation:
When you draw an illustration for this problem, you would come up with the same drawing as shown in the picture. As the hot-air balloon travels upwards, there is a slight time when the bag of sand rises up until it reaches the maximum height. Then, it goes back down to the ground. The total time would be t₁ + t₂. The solution is as follows:
H = v₀²/2g = (2.45)²/2(9.81) = 0.306 m
t₁ = H/v₀ = 0.306 m/2.45 m/s = 0.125 s
t₂ = √2(H + 98.8)/g = √2(0.306+ 98.8)/9.81
t₂ = 4.495 s
Total time = 0.125 s + 4.495 s = 4.62 seconds
Answer:
The frequency of the signal is 2 GHz
Explanation:
Given;
period of the clock signal, T = 500 ps = 500 x 10⁻¹² s
the frequency of the signal is given by;

F = 2 GHz
Therefore, the frequency of the signal is 2 x 10⁹ Hz or 2 GHz
<span>Efficiency is the measure
of how efficient a process is. It is used to assess the ability of a process in
avoiding waste energy, materials, money and time in doing a desirable output.
It is calculated in thermodynamics as:
Efficiency = 1 - Tc / Th
</span>Efficiency = 1 - 210 / 490
Efficiency = 0.57
