In the balanced nuclear reaction of uranium 235, we have thorium 231, helium atom and energy released at the right of the equation
<h3>
Balanced nuclear reaction of Uranium</h3>
The balanced nuclear reaction of uranium is determined as follows;
Thus, in the balanced nuclear reaction of uranium 235, we have thorium 231, helium atom and energy released at the right of the equation while uranium 235 is on the left hand side of the nuclear reaction equation.

Answer:
b
Explanation:
it loses energy due to friction because if it hits objects the objects slow it down and which causes it to start slowing down
Answer:
B. Millions of years of high pressure and temperature.
- Millions of years of high pressure and temperature the ancient forests turn into fossil fuels.
Explanation:
Fossil fuels were formed from the dead remains of living organisms millions of years ago. They were formed under high pressure and high temperature.
- Coal : about 300 million years ago the earth had this forest in low lying wetland areas. Due to natural processes like flooding, these forest god buried under the soil. As more soil deposited over them, they were compressed. Under high pressure and high temperature, dead plants got slowly converted into coal.
- Petroleum : Petroleum was formed from organisms living in the sea. As these organisms died, their bodies settled at the bottom of the sea and got covered with layers of soil and clay. Over millions of years, absence of air, high pressure and high temperature transformed the dead organisms into Petroleum.
Coal, Petroleum and natural gas are fossil fuels.
