A block with mass m = 4 kg is sitting on the ground and not moving. The acceleration due to gravity is g = 9.81 m/s2. Please answer the following questions. a) Write an expression for the magnitude of the force of gravity Fg on the block. b) Calculate the magnitude of the force of gravity Fg on the block in Newtons. c) In what direction is the force of gravity in this problem? Sideways. All of these choices. Upwards. None of these choices. Downwards. Force doesn't have a direction. d) What is the magnitude of the normal force FN in Newtons? e) In what direction does the normal force act? Sideways. All of these choices. Downwards. None of these choices. Upwards. Force doesn't have a direction.
With the rod initially horizontal, a 44 gm wad of wet putty drops onto one of the balls with a speed of 3.7 m/sec and sticks to it.
Light is incident on a slit 0.750 mm wide. On a screen 2.00 m away, the distance from the central maximum to the first minimum is 1.35 mm. compute the wavelength of the light.
An arrow is fired horizontally with a speed of 68. m/s directly at the bulls eye of a target 50 m away. When fired, the arrow is 120-m above the ground. How far short of the target does it strike the ground.
Two charges are placed on the x axis. One charge (q1 = +12.5 µC) is at x1 = +3.0 cm and the other (q2 = -13 µC) is at x2 = +9.0 cm. Find the net electric field (magnitude and direction) at the following locations. (a) x = 0 cm magnitude N/C direc..
At a factory, a noon whistle is sounding with a frequency of 480-Hz. As a car travelling at 79 km/h approaches the factory, the driver hears the whistle at frequency fi. After driving past the factory.
A conveyor belt at a quarry lifts 2,000 kg of sand per minute up a vertical distance of 12 meters. The sand is at first at rest, then moves at a speed of 0.20 m/s along conveyor belt. What is the instantaneous power generated by this machine .
Assuming you can't use the electric heater, you put 0.2kg of water at 20(C) in a thermous. If you move the water up and down a height 10cm twice/second, how long must you shake the water to raise the temperature to 100(C)?
A jetliner is moving at a speed of 258 m/s. The vertical component of the plane's velocity is 85.8 m/s. find the magnitude of the horizontal component of the plane's velocity.
A child's toy consists of a piece of plastic attached to a spring. The spring is compressed against the floor a distance of 1.2 cm, and the toy is released. If the spring constant is 103 N/m, what is the magnitude of the spring force acting on the..
