These plans are an accompaniment to mechanical lifting devices in reducing on-the-job injuries. they address specific patient needs, the degree of assistance required, and special treatments that can reduce on-the-job injuries. what are they called?

It is really hard for me right know

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
