A bicycle has a mass of 20 kg. A small car has a mass of 1,000 kg. A force is applied to accelerate the car from a standing position to a speed of 1 m/s. If the same force that was applied to the car is applied to the bicycle at rest, to what speed will the bicycle accelerate in one second? A. 0.002 m/s
B. 1 m/s
C. 20 m/s
D. 50 m/s

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

Atotal charge of –6.50 µc is uniformly distributed within a sphere that has a radius of 0.150 m. what is the magnitude and direction of the electric field at 0.300 m from the surface of the sphere? a) 2.89 × 105 n/c, radially inward b) 6.49 × 105 n/c, radially outward c) 4.69 × 105 n/c, radially inward d) 9.38 × 105 n/c, radially outward e) 1.30 × 106 n/c, radially inward
