Answer:
A
Explanation:
According to law of conservation of momentum, the total momentual in the system will be conserved
Answer:
2500N
Explanation:
f = m.a
m=500 kg
a=5 m/s²
f = 5*500 kgm/s² = 2500 N
Answer:

Explanation:
A) In order to solve the table it is necessary to consult tables A11-E and A10E for refrigerant R134-a
In this way we obtain that:

In this way,


In this way the entropy change is,

B) Whenever entropy yields a positive result, the process can be carried out adiabatically.

cross sectional area ( A ) = 1 cm^2
distance x = 1 cm
attached below is a detailed solution
The frequency of a photon with an energy of 4.56 x 10⁻¹⁹ J is 6.88×10¹⁴ s⁻¹.
<h3>What is a frequency?</h3>
The number of waves that travel through a particular point in a given length of time is described by frequency. So, if a wave takes half a second to pass, the frequency is 2 per second.
Given that the energy of the photon is 4.56 x 10⁻¹⁹ J. Therefore, the frequency of the photon can be written as,

Hence, the frequency of a photon with an energy of 4.56 x 10⁻¹⁹ J is 6.88×10¹⁴ s⁻¹.
