A40 foot fiberglass boat hull weighs 2000 kg. 60% of that is a fully cured crosslinked polyester resin (the remainder is the glass reinforcing fibers, pigment, fillers, what is the molecular weight of the polymer (in g/mol)?

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
