A planet orbiting a distant star has been observed to have an orbital period of 0.76 Earth years at a distance of 1.2 AU. What is the mass of the star the planet is orbiting? Round your answer to the nearest tenth.

Three cars (car f, car g, and car h) are moving with the same velocity when the driver suddenly slams on the brakes, locking the wheels. the most massive car is car f, the least massive is car h, and all three cars have identical tires.

Acceleration involves a change in speed or what?

onsider a half-wave rectifier circuit with a triangular-wave input of 5-V peak-to-peak amplitude and zero average, and with R = 1 k?. Assume that the diode can be represented by the constant-voltage-drop model with VD = 0.7 V.

How far (in meters) above the earth's surface will the acceleration of gravity be 85.0 % of what it is on the surface?

What is the relationship between the mass of the counterweight and the amount of work done on the projectile?
