An engineer wants a 4000kg helicopter to fly horizontally (neither gaining nor losing altitude) and increase speed at a rate of 2.6 m/s2 despite experiencing a 1000N drag. How many forces are acting on the helicopter?

Are all the forces on the helicopter balanced?

What is the magnitude of the net force on the helicopter?

What is the strength of the horizontal thrust component?

What is the strength of the thrust?

At what angle, theta, does the helicopter need to tilt?

Attached is a screenshot of the question.

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
