Answer:
0.304 m/s2
Explanation:
If the first child is pushing with a force of 69N to the right and the 2nd child is pushing with a force of 91N to the left. Then the net pushing force is 91 - 69 = 22 N to the left. Subtracted by 15N friction force then the system of interest is subjected to F = 7 N net force tot he left.
We can use Newton's 2nd law to calculate the net acceleration of the system
His hands being on the pole creates the thermal energy because of the friction being made by sliding down the pole.
A microscope is an instrument from which you can see the cells of an object.
It helps you to observe the cells of substance.
Powerful microscopes helps better in observing minute particles or bacterias.
Hope it helps...
I don’t know but maybe is Thermal Energy
Answer:
A naturally radioactive element of the actinide metals series. Plutonium is used as a nuclear fuel, to produce radioisotopes for research, Plutonium dioxide is formed when plutonium or its compounds (except the phosphates) are ignited in air, and Plutonium oxide fired at temperatures 600 C is difficult to rapidly.
