Answer: A) Transformer
Explanation: A Transformer is an apparatus, device or a component in a system that is used to convert high voltage into low voltage. It is used to either increase or decrease the voltage of an alternating current.
A transformer uses the basic principle of electro magnetic induction, having two or more coils, the voltage is changed from one coil to another but with thesame frequency as alternating current energy passes through them.
Acceleration = vf-vi /t
10-22/3=2.6m/s^2
#1.
<em>Car </em>1<em> weighs </em>300 kilograms<em> and is moving right at </em>3 meters per second (m/s)
#2.
Law of conservation of momentum
momentum before collorion = momentim after collosion
MV + mv = MV' + mv'
1500x25+ 1000x5
37500 + 15000
Answer:
Rms speed of the particle will be 
Explanation:
We have given mass of the air particle 
Gas constant R = 8.314 J/mol-K
Temperature is given T = 
We have to find the root mean square speed of the particle
Which is given by 
So rms speed of the particle will be
