If you increase the frequency of a sound wave four times, t<span>he speed will increase four times. The correct option among all the options that are given in the question is the first option or option "A". This also shows the frequency and speed of the waves are directly proportional to each other. I hope it helps you.</span>
Answer:
So the car was speeding more moving towards North
Explanation:
As we know that during the collision of two cars total momentum before collision and after collision must be conserved
So here we can say that after collision two cars are locked and moved together Exactly towards North-East
So here momentum of two cars must be exactly same before collision in East and North directions
So we will have
So the car was speeding more moving towards North
Answer:
Magnetic field = 1.41 T
Explanation:
Magnetic field of solenoid, B = μnI
μ = 4π x 10⁻⁷N/A²
Number of turns per meter,
Current, i = 18.2 A
B = μnI = 4π x 10⁻⁷ x 6.15 x 10⁴ x 18.2 = 1.41 T
Magnetic field = 1.41 T
I will post my work, but is that 99 degrees Celsius and 25 degrees Celsius?
All you have to do is plug in the initial temperature for gold where it says Tg and the initial temperature for the water where it says Tw and then plug that in and you will have your answer.
