If a metallic wire of cross sectional area 3.0 ´ 10 - 6 m2 carries a current of 6.0 A and has a mobile charge density of 4.24 ´ 1028 carriers/m3, what is the average drift velocity of the mobile charge carriers? (charge value = 1.6 ´ 10 - 19 C)

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

State one advantage and one disadvantage of using a plane mirrior as a driving mirrior

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
