![]() Given that q = +15 ♜, find the distance from q1 where q2 experiences a net electrostatic force of zero? (The charges q1 and q3 are separated by a fixed distanceĪ car is traveling at 28 m/s when the driver spots a large pothole in the road a distance 37 m ahead. Suppose the charge q2 can be moved left or right along a line connecting charges q1 and q3. What is the total up and down distance moved by the wave particle for each cycle of the wave? How many cycles of the wave would have to pass by a The speed of a transverse wave on a string is 450m/s, while the wavelength is 0.18m. If the distance from the runner to the center of the track is 28.2 m, what is the centripetal acceleration of the runner? What would his weight (the gravitational force due to the Earth) be if he tripled his distance from the center of the Earth by flying in a spacecraft?Ī runner is moving at a constant speed of 8.00 m/s around a circular track. Joe has a weight of 850 N (about 193 lb) when he is standing on the surface of the Earth. What would his weight (the gravitational force due to the Earth) be if he tripled his distance from the center of the Earth by flying in a spacecraft? Joe has a weight of 900 N (about 204 lb) when he is standing on the surface of the Earth. t 0 4 8 12 16 20 v(t) 43 42 40 35 25 5 Estimate the distance traveled by the particle between t = 0 sec The following table gives the velocity v(t) (in feet per sec) at different instances of time t (in sec) of a particle moving along a horizontal axis. If the spot from where they start sliding down is located 7 meters above the water’s surface, calculate the angle of the ramp with the horizontal. In a water park, people walk a distance of 20 meters up an inclined ramp before getting on a water slide. The wheel is rotating with a non-zero angular acceleration. Mass 1 is located at the rim of the wheel while mass 2 is located halfway between the rim and the axis of rotation. Two objects of equal mass are on a turning wheel. so I can plug in d and rĪ car traveling 75 km/jam slows down at a constant 0,50 m/s2 just by “letting up on the gas.” Calculate (a) the distance the car coasts before it stops, (b) the time it takes to stop, and (c) the distance it travels during the first and fifth seconds. d = sqrt(2rh+h^2) d = distance to the horizon h = height above sea level for the observer. Determine the length of the longer diagonal of the parallelogramįormula for distance to the horizon for a satellite in orbit. The area of the parallelogram is 720 cm^2, and its perimeter is 140 cm. The distance between the center of symmetry of a parallelogram and its longer side is equal to 12 cm. how do scientists classify stars ? (1point ) A. If it takes 4 hours to drive the distance at 35 miles per hour, how long will it take to drive the same distance at 45 miles per hour? about 3.11 hours********* 140 hoursġ8. The time t required to drive a certain distance varies inversely with the speed r. The smaller pole being between the taller pole and P and at distance of 20m from P the angle of elevation of the top T of the taller pole from the top R of the The teet of two vertical poles of height 3m and 7m are in line with a point P on the ground. Why does a planet's orbital radius represents that planet's average distance from the sun and not its exact distance? When the distance d between the slits is relatively large, there will be numerous bright spots, called fringes. A double slit located a distance x from a screen, with the distance from the center of the screen given by y.
