Answer:
10 ms⁻¹
Explanation:
The amount of momentum that an object has is dependent upon two factors
- mass of the moving object
- speed of motion
In terms of an equation,
Momentum (P) = Mass(m)×velocity(v)
P = m×v
600 = 60 × v ⇒ v = 10 ms⁻¹
Answer: correct option is C
both Technicians A and B are right
Explanation:
Test cycles specify the specific conditions under which the engine or vehicle is operated during the emission test. The vent valve that is not able to close can cause the system to fail the on-board test. Also, a leaking gas cap can cause a failure of the EVAP test.
There are many different test cycles issued by various national and international governments and working groups
Electromagnetic waves carry sound
J.J. Thomson used a cathode ray tube to discover the electron. Cathode ray tubes are vacuum tubes that contain two electrodes - one on each side. One of the electrodes (the cathode) fires electrons at the other (the anode) when voltage is added to the system.
