The tapeats sandstone is made of sand-sized rock pieces and contains fossils of trilobites. trilobites were marine organisms similar to modern-day horseshoe crabs. in which kind of environment did the tapeats sandstone most likely form and why? geologic history unit assessment, part 2 a lake environment because trilobites live in the fresh water and there are small sediments in the rocks
a. a beach environment because trilobites live in the ocean and there are sand particles in the rocks
b. a coral reef environment because the particles in t

For problems 1-3, consider a simple dc brush motor with a permanent magnet stator. with an an consider a simple dc brush motor with a permanent magnet ae supply voltage of 100 v, the no-load speed of the motor is 1000 rpm. this motor can provide a torque of 1.9 n-m at 800 rpm drawing a current of 2 a current are both zero at no load.) 1. with an armature supply voltage of 100 v, the motor is operated at 900 rpm. what is the motor torque? what is the mechanical power delivered by the motor? what is the current draw? what is the electrical power input? what is the energy efficiency of the motor? with an armature supply voltage of 100 v, the motor is operated at 1100 rpm (where it acts as a generator). what torque input is required? what mechanical power is required what current is generated? what is the electrical power generated? what is the energy efficiency of the motor acting as a generator? 2. with an armature supply voltage raised to 120 v, the motor is operated at 1000 rpm. what is the no-load speed? what is the motor torque? what is the mechanical power delivered by the motor? what is the current draw? what is the electrical power input what is the energy efficiency of the motor? 3.
