Physics
A horse is harnessed to a sled having a mass of 236 kg, including supplies. The horse must exert a force exceeding 1 240 N at an angle of 35.0° in order to get the sled moving. Treat the sled as a point particle. (a) Calculate the normal force on the sled when the magnitude of the applied force is 1 240 N. (b) Find the coefficient of static friction between the sled and the ground beneath it. (c) Find the static friction force when the horse is exerting a force of 6.20 3 102 N on the sled at the same angle

Explanation:
It is given that,
The diameter of a white blood cell is 12 micrometers
The diameter of white blood cell according to a model is 24 micrometers.
We need to find the ratio of model size to actual size. It can be done as follows :
Hence, the ratio of model size to actual size is 2:1.
