Given that amplitude and energy are related, the amplitude of a wave is dependent upon A. the amount of energy carried by the wave.
These two are connected, so one affects the other and vice versa.
To solve this we assume
that the gas inside the balloon is an ideal gas. Then, we can use the ideal gas
equation which is expressed as PV = nRT. At a constant pressure and number of
moles of the gas the ratio T/V is equal to some constant. At another set of
condition of temperature, the constant is still the same. Calculations are as
follows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 =313.15 x 3.50 / 298.15
<span>V2 = 3.68 L</span>
As per the information given, there's most probability that the air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
Answer: Option A
<u>Explanation:</u>
According to the concepts of the specific heats capacity of matter; it is observed that water possesses high specific heats capacity as compared to metals and other solids. Water takes much more time to absorb heat from the atmosphere and the same way takes time while releasing it into the atmosphere.
Whereas, solids and most metals have the tendency to quickly absorb and release the heat. Hence, it seems that the student may observe the rise in temperature for the air over the water lake later in the day which will stay warm longer than the air over the ground.
Answer:
(i) The angular speed of the small metal object is 25.133 rad/s
(ii) The linear speed of the small metal object is 7.54 m/s.
Explanation:
Given;
radius of the circular path, r = 30 cm = 0.3 m
number of revolutions, n = 20
time of motion, t = 5 s
(i) The angular speed of the small metal object is calculated as;
(ii) The linear speed of the small metal object is calculated as;
Answer:The answer is A,B and C
Explanation: it can be use to learn universe behavior,it is also use for the measurements of velocity of galaxy,and is can also be use to indicate,galaxy motion.
Doppler effect,measures the speed which star and galaxy are moving away from us or towards us. It shows the color of wavelength to be either red shift or blue shift.
