Q1. A bus travelling along the straight road at 100km/hr-1 and the bus conductor make at 6kmhr-1 on the floor of the bus in the same direction on the bus. Find the speed of the conductor relative to road and relative to the bus. If the bus conductor now makes at the same rate but in opposite direction as the bus. Find his new speed relative to the road.
Q2. A loudspeaker of mass 17.0 {rm kg} is suspended the distance of h = 1.70 {rm m} below the ceiling by two cables that make equal angles with ceiling. Each cable has the length of l = 2.70 {rm m}. What is the tension T in each of the cables? Use 9.80 {rm m/s} ^2 for the magnitude of the acceleration due to gravity.
Discover the magnitude of acceleration
Elucidate the spacing between peaks
A 72 person stands on a uniform ladder 4.5 long, that weighs 75. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force.
An archer puts a 0.54 kg arrow to the bowstring. An average force of 202 N is exerted to draw the string back 1.3 m. suppose that air resistance is negligible.
If air resistance & other effects are ignored how far away did the shell hit.
What is closing equilibrium temperature of the tin-water
Compute magnitude of the average emf
A 56.0 resistor is connected in parallel with a 117.0 resistor. This parallel group is connected in series with the 27.0 resistor. The total combination is connected across a 15.0 V battery. What is the current of the 117 resistor? What is the power ..
The link between portfolio level objectives with portfolio success factors that are achieved through individual projects and points out how contributes to strategic fit, use of synergies, etc.
A very long non conducting cylinder of diameter 10.0 cm carries charge distributed uniformly over its surface. Each meter of length carries +5.50 C of charge. A proton is released from rest just outside the surface.
A 238 g particle is released from rest at point A inside a smooth hemispherical bowl of radius 32.5 cm.compute the gravitational potential energy at A relative to B.
A particular guitar string is supposed to vibrate at 214 Hz, but it is measured to actually vibrate at 272 Hz. By what percentage must the tension in string be changed to get the frequency to the accurate value.
