Answer:
0m/s²
Explanation:
A body with a constant speed always has a zero acceleration
Hence if Korey ran around the track at 10 meters per second and had a constant speed and did not change directions, then his acceleration will be 0m/s² not considering his initial speed
Answer:
0.286
Explanation:
Let g = 10m/s2, and assume the pulley is frictionless, the weight by the 10kg block would exert a force on the 35kg block on the ground
Weight of the 10 kg-block = mg = 10 * 10 = 100 N
This force is balanced by static friction force from the ground due to the normal force of the 35kg block. So the friction force would also be 100N
The weight and normal force of the 35kg block is N = Mg = 35*10 = 350 N
The coefficient of the friction force if friction force divided by normal force:
Almost all the electricity used by people is produced by the 3 forms of power plants, namely fossil, hydro, and nuclear. Fossil fuel power plants burn carbon fuels such coal, oil or gas to generate steam that drives large turbines to produce electricity. Hydro power plants generate electricity by storing water in big reservoirs behind large dams. Water from the dams flows through turbines to generate electricity. Nuclear power plants use the heat produced by nuclear fission to generate steam that drives turbines, like in fossil fuel plants.
Answer:
Since N/m is the unit of spring constant N/nm would be the possible unit for a spring constant.
