<h3>
Answer: 22.5 m/s</h3>
=====================================================
Work Shown:
acceleration = ( finalVelocity - initialVelocity )/(change in time)
1.5 = (60 - x)/(25)
1.5*25 = 60-x
37.5 = 60-x
x = 60-37.5
x = 22.5
The initial velocity is 22.5 m/s
Answer:
radio
microwave
Infrared
Visible
Ultraviolet
X-ray
Gamma ray
I hope this helps you a little bit

This is an accordance with Newton's First Law of Motion, stating that objects in motion remain in motion and objects at rest remain at rest unless acted upon by an external force.
Answer:
Explanation:
Given that
There's a change in friction from 440 kJ to 110 kJ
This change is as a result of conversion of energy. The energy of the car system converted the mechanical energy in it, into a corresponding heat energy. During the course of this conversion, is where a whopping 330 kJ of energy went missing.
The 330 kJ of energy was lost as a result of the conversion of mechanical energy into heat energy by the use of friction.
Answer:

Explanation:
Given that
T₁ = 290 K
P₁ = 100 KPa
Power P =5.5 KW
mass flow rate

Lets take the exit temperature = T₂
We know that


If we assume that process inside the compressor is adiabatic then we can say that





That is why the exit pressure will be 4091 KPa.
