Answer:
A. It is always a positive force
Explanation:
Hooke's law describes the relation between an applied force and extension ability of an elastic material. The law states that provided the elastic limit, e, of a material is not exceeded, the force, F, applied is proportional to the extension, x, provided temperature is constant.
i.e F = - kx
where k is the constant of proportionality, and the minus sign implies that the force is a restoring force.
The applied force can either be compressing or stretching force.
20 ohms in parallel with 16 ohm= 8.89
20x16/20+16. Product over sum

Keep more fruits, low-fat dairy products (low-fat milk and low-fat yogurt), vegetables, and whole-grain foods at home and at work.
Explanation:
Answer:
31.68 meters per second.
Explanation:
Speed is equals to Distance divided by Time, so, this means that speed is inversely proportional to time and directly proportional to distance.
Here, Distance is given which is 274 meters.
Time taken to cover the given distance is 8.65 seconds.
So, by putting the values of distance and time in the formula of speed we will get the top speed of Cheetah which is 31.68 meters per second.
