Answer:
a round shape. It has its own gravity to pull itself into a round shape
It’s b because if you’re running at 5 miles per second being a 100kg weight is the fastest
Here is how I would I explain it. Water is channeled through tunnels in the dam. The energy of water flowing through the dam’s tunnels cause turbines to turn. The turbines make generators move. Generators are machines that produce electricity. Engineers control the amount of water let through the dam. The process used to control this flow of water is called the intake system.
Hope this helps can’t do the diagram part.
Answer: It is a transverse wave ^^
Explanation:
Answer: 567 N
Explanation:
If the weight of the person and the bike are supported equally by the two tires, this means that the force acting on each tire, is half of the total weight.
We know that the gauge pressure in one tire, by definition, is equal to the force on the tire, over the contact surface between each tire and the road, so we can write:
P= F/A = (mrider g + mbike g) / A = (Fgrider + 7.5 kg. 9.8 m/s2) / 703 mm2 (1)
As the pressure data is given in lb/in2, it is needed to convert to N/mm2, as follows:
65.5 lb/in2 = 0.455 N/mm2.
Replacing in (1), and solving for Fgrider, we have:
Fgrider = 567 N
