Which of the following best reflects why lighting systems are used when filming on location outdoors? (Select all that apply.)

Digital cameras need strong concentrated light to produce any images, so natural light is not sufficient.

Strong light means lower-cost production, so artificial light saves money on processing.

To produce a film image you have to manage how light interacts with the film or digital media, and “natural” light may not look natural.

Because filming on location is expensive, it is often important to be able to film even when the weather does not cooperate.

5.a fishing rod is formed from a composite material of 0.5 kg of glass fibers embedded in a matrix of 0.5 kg of epoxy resin. the glass fibers are assumed to be long, continuous and unidirectional. to achieve a greater stiffness it is proposed to use a different composite that is comprised of long continuous carbon fibers that will be embedded in a matrix of 0.5 kg of epoxy resin. if the modulus of elasticity of the carbon fiber composite is 10% greater than the elastic modulus of the glass fiber composite, estimate the mass of carbon fibers that will be used to make the carbon fiber composite. assume the applied tensile stress is parallel to the direction of the long axis of the fibers. the epoxy resin, glass fiber, and carbon fiber have an elastic modulus of 5, 86, and 350 gpa respectively and a density of 1100, 2500, and 1800 respectively.
