A disk with a radius of 0.1 m is spinning about its center with a constant angular speed
of 10 rad/sec.
What are the speed and magnitude of the
acceleration of a bug clinging to the rim of the
disk?
1. 0.1 m/s and 1 m/s2
2. 1 m/s and 0 m/s2
(Disk spins at constant
speed.)
3. 1 m/s and 10 m/s2
4. 10 m/s and 10 m/s

Acharge of 8.4x10^-4 c moves at an angle of 35 degrees to a magnetic field that has a field strength of 6.7x10^-3 t. if the magnetic force is 3.5 x10 ^-2 n, how fast is the charge moving?

If the wheels lock when braking suddenly the vehicle: a: loses traction b: lose steering wheel ability c: gain speed slightly d: gain steering ability

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
