Will give brainliest if you are correct. which of the following statements best explains how voyager 1 and voyager 2 have made outer space exploration easier? their high-gain antenna has produced magnetic fields. their magnetometer sends data back to earth very fast. they have been able to detect particles in outer space. they have used photopolarimeters to measure the charged particles.

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.
