Q1. Conclude the force required through A for the system to remain in static equilibrium in horizontal (not moving side to side). The forces at B and C are 40 N and 90 N
Q2. If the mass of both weights is 175gm, the first mass is located 20 north of east, the second mass is located 20 south of east, and the transducer sensitivity is 0.5volts/Newton, how large a voltage do you expect to measure? Imagine the transducer has been properly zeroed so that V = 0 when F3=0.
Treating our rigid legged friend as a particle, what is the average force his feet exert on the ground as he slows down.
A civil engineer wishes to plan a curved exit ramp for a highway in a way that a car will not have to rely on friction to round the curve without skidding. In the other words, a car moving at the designated speed can negotiate the curve even while th..
What would be the potential difference VC - VB across the thin resistor if the battery emf is 4.00 volts? Suppose that the electric field in the thick wires is very small (so that the potential differences along the thick wires are negligible)
A student pulls a box of books on a smooth horizontal floor with a force of 100 N in a direction of 37 degrees above the horizontal. If the mass of the box and the books is 40 kg, what is the normal force on box? a. 332 N b. 312 N c. 392 N d. 292 N
The maximum distance from Earth to the Sun (at our aphelion) is 1.521 x 10^11 m and the distance of closest approach (at perihelion) is 1.471 x 10 ^11 m. Assume the Earth's orbital speed at perihelion is 3.027 x 10 ^ 4 m/s. (overlook the effect of th..
The wind blows with a force of 425N north on a sail boat, while the water exerts a force of 325N west on the sailboat. Find out the magnitude and direction of the net external force on the sailboat.
How numerous years would it take a thermally insulated one-million-kilogram chuck of granite to undergo a 1000k boost in temperature?
A fire in an enclosure has reached flashover, & the gas temperature is assumed to be uniform at 1000oC. The enclosure has an opening 3 m wide & 2 m high. Find the position of the neutral layer, measured from the bottom of the opening.
Compute the scalar product V.F
A car travelling at 37 {rm m/s} runs out of gas while travelling up a 7.0{rm ^ {circ}} slope. How far would it coast before starting to roll back down.
Points A and B have electric potentials of 320 and 160, respectively. When an electron released from rest at point A arrives at point C, its kinetic energy is.
Two spherical objects have a combined mass of 200. The gravitational attraction between them is 8.01×10-6 while their centers are 21.0 apart.
