Please help
I need help on the first one
Answer is give below
Explanation:
when any object or spacecraft is located exactly between Earth and Mars.
than Earth gravitational force will be exerted on spacecraft more than the Mars gravitational force.
as we know that gravity on the Mars is less than the gravity on the Earth
so spacecraft will move very slowly toward the Earth.
gravity force on Earth = 9.807 m/s²
gravity force on Mars = 3.711 m/s²
Seismic stations consist of a seismometer for sensing ground motion, a clock for determining time, and a recorder for collecting data of earthquakes. They detect and measure Earth's ground motion.
Hope this helps!
