A wire with mass 40 g is stretched so that it’s ends are tied down at points 80cm apart. The wire vibrates in its fundamental mode with frequency 60Hz and amplitude of 0.3 cm at antibodies. What is the speed of propagation of transverse waves in the wire?

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

Your target variable is δf, the magnitude of the difference in frequency between the waves emitted from the sonar device and the waves received by the device after reflecting off the whale. write an expression for δf in terms of the relevant frequencies using the subscript notation introduced above.

Polly is pushing a box across the floor with a force of 30 n. the force of gravity is –8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?
