Light gates are more reliable. When using a manual stop watch, it is difficult to stop it at an exact time. A light gate is able to detect when an object passes through a 'gate' with the infrared transmitter and receiver.
Answer:
Given values of Planck Constant are equivalent in English system and metric system.
Explanation:
Value of Planck's constant is given in English system as 4.14 x 10⁻¹⁵eV s.
Converting this in to metric system .
We have 1 eV = 1.6 x 10⁻¹⁹ J
Converting
4.14 x 10⁻¹⁵eV s = 4.14 x 10⁻¹⁵x 1.6 x 10⁻¹⁹ = 6.63 x 10⁻³⁴ Joule s
So Given values of Planck Constant are equivalent in English system and metric system.
Yes, his velocity will decrease the further he slides.
Answer:
p waves travel faster than s waves and surface waves
Answer:
11
Explanation:
According to Boyle's law:
Thus,
Where, n is the number of the balloons
From the question, it is given that:
For balloon:
P = 
Pa
V = 0.040 m³
For cylinder:
P = 
Pa
V = 0.0031 m³
So,
n = 11.625
<u>So, Maximum number of balloons = 11</u>
