Answer:
Incorrect statement is (b).
Explanation:
Option (a) : There is an inverse relation between the time and the frequency. The time taken depends on the frequency of the number of oscillations. Statement 1 is correct i.e. the time taken by any point of the wave to make one complete oscillation does not depend on the amplitude.
Option (b) : Speed of a wave is given by the product of its frequency and wavelength. It is not necessary that doubling the wavelength of the wave will halve its frequency as speed depends on the medium.
Option (c) : Doubling the amplitude has no effect on on the wavelength as amplitude does not depends on its wavelength.
Option (d) : Since, 
Speed is directly proportional to the frequency and wavelength. So, doubling the frequency of the wave will double its speed. So, the incorrect statement is (b).
The unit 'mb' means millibar which is equivalent to 1/1000 of 1 bar. To convert the units from bar to atmospheres (atm) and to inches Hg (inHg), we need to know the conversion factors.
a.) 1 atm = 1.01325 bar
0.92 mb(1 bar/1000 mbar)(1 atm/1.01325 bar) =<em> 9.08×10⁻⁴ atm</em>
b.) 1 bar = 29.53 inHg
0.92 mb(1 bar/1000 mbar)(29.53 inHg/1 bar) =<em> 0.027 inHg</em>
DIAMONDS are NOT rocks. Diamonds are minerals, rocks are made up of many different fragments of minerals.
Answer:
a= F/m
Explanation:
Newton's Second Law of Motion : It states that that the rate of change of momentum of a body is proportional to the applied force and it takes place on the direction of the force applied.
Mathematically,
F = m ( v-u)/t
F = ma
a = F/m
The same force was applied to each of the balls yet, the acceleration of one was greater than the other. The kickball accelerated at a greater pace than the soccer ball because it has a lesser mass hence the effect or impact of the force applied will be greatly felt by the kickball.
