in the scenario. We have a trumpet year who's producing a frequency off 3 880 herds. But the onlooker can hear 888 herds because the trumpet here is moving towards them and the suite of the sound is given and we want to find the speed off moment. That is very simple. We know that beautiful daughter effect frequency heard is original frequency times. See if I see mine a screen in the case off the source moving towards the observer. We use this so the Upsell frequencies 80 it hurts is equal to 8 80 hurts. Heinz C is 3 38 meter per second, divided by 3 38 minus. We we simply need to solve this equation. We send this court to the other side and we have 88 times 3 38 minus 8 88 times. We is equal to 8 80 kinds. 3 38 Wilson one time over there on the other over here and we have 88 week is people do 88 guns 3 38 minus 80 dunks 3 38 which is eight times 3 38 Therefore, we is eight times 3 38 by 8 88 which turns out to be 3.45 meters per second symbol is that but because we have only three significant digits will wrong date at 3.4? Why is not here, Symbolist?
