In a circus performance, a large 3.0 kg hoop with a radius of 1.3 m rolls without slipping. if the hoop is given an angular speed of 6.8 rad/s while rolling on the horizontal and is allowed to roll up a ramp inclined at 24◦ with the horizontal, how far (measured along the incline) does the hoop roll? the acceleration of gravity is 9.81 m/s2 .

Diamond will scratch quartz. true or false

Need asap ‼️ 20 pts which gravitational force field diagram is drawn correctly? (answers in pictures below)

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
