Can anyone help me with physics?
Hey, I'm having trouble with the following task. I would be very grateful if someone with some insight could help me. Best regards
The task is: A projectile is fired horizontally from a height of 1.5 m in a biathlon competition, with a launch velocity of 550 m/s. The target is 100 m away. How many mm will the projectile fall before reaching the target? I would be very happy to receive an answer 🙂
Hello, Does anyone have an idea how to solve this problem? Task: A spherical converging mirror (radius of curvature r = 15.0 cm) is illuminated by a parallel beam of light (parallel to the optical axis). Consider the rays that are at distances d = 10.0, 30.0, 50.0, and 70.0 mm from the axis. Calculate…
Hello, Does anyone know how to calculate the depth of an ocean given the frequency of an echo, the time it takes to reach the echo, and the pressure? (The topic: waves, vibrations). It may be that some given things are not needed.
Hi, does anyone know how to solve this problem? How much energy in kWh is contained in 26 kg of wood? against: m= 16 kg, H=15 MJ/kg Thank you in advance
Look at this:
