WebThe rate of change of the oil film is given by the derivative dA/dt, where. A = πr 2. Differentiate both sides of the area equation using the chain rule. dA/dt = d/dt (πr 2 )=2πr (dr/dt) It is given dr/dt = 1.2 meters/minute. Substitute and solve for the growing rate of the oil spot. (2πr) dr/dt = 2πr (1.2) = 2.4πr. WebThe speed is: s = 27.0 km/h. s = 7.50 m/s. Converting the units, the speed is 7.50 m/s. The time the cart traveled for was: t = 10.0 min. t = 600s. The speed of the cart and the time of travel are given, so the distance traveled …
WebTo find the speed, distance is over time in the triangle, so speed is distance divided by time. To find distance, speed is beside time, so distance is speed multiplied by time. , , , , s = speed (meters/second) d = distance traveled … WebSep 12, 2024 · The pulse moves as a pattern that maintains its shape as it propagates with a constant wave speed. Because the wave speed is constant, the distance the pulse moves in a time Δt is equal to Δx = vΔt (Figure 16.3.1 ). Figure 16.3.1: The pulse at time t = 0 is centered on x = 0 with amplitude A.
WebSep 12, 2024 · Figure 16.3.1: The pulse at time t = 0 is centered on x = 0 with amplitude A. The pulse moves as a pattern with a constant shape, with a constant maximum value A. … WebSpeed Triangles – Speed = Distance / Time The speed is the distance travelled per unit of time. Common units of speeds are miles per hour (mph) or metres per second (m/s). To …
WebDec 25, 2024 · Shutter speed controls how long the sensor of the camera is exposed to light. Shutter speed is measured in fractions of a second. For example, a shutter speed of 1/60 holds the shutter open for one sixtieth of one second. The longer the shutter speed is in time the more light is let in. If it is shorter in time, less light is let in.
