The figure shows shows an object's acceleration-versus-force graph. Suppose a0 = 2. 2 m/s2. What is the object's mass, in kg? enter a number only, without units.

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Find the magnetic field a distance r from the center of a long wire that has radius a and carries a uniform current per unit area j in the positive z direction.
