ummmm it might be 300... i used a calculator
sorry if it is wrong
Answer:
Have a blessed day!
Explanation:
The energy to launch the spacecraft came from moving the spacecraft against the magnetic force. The energy used to move a magnet against a magnetic force is stored as potential energy in the magnetic field. This magnetic force can convert potential energy stored in the magnetic field to kinetic energy.
Please give brainliest!
Acceleration is change is velocity over time. So the change in velocity is 40 and time is 4.5 sec. So the acceleration is 40/4.5=8.89 m/s^2
Answer:
a. A dissipative interaction permits a two-way conversion between kinetic and potential energies.
FALSE
in dissipative type of forces energy is not conserved so it is not possible
b. A nondissipative interaction permits a two-way conversion between kinetic and potential energies.
TRUE
in non dissipative type of force there is no energy loss so we can use energy conservation
c. A potential energy function can be specified for a dissipative interaction.
FALSE
Here potential energy is not defined for dissipative type of forces
d. A potential energy function can be specified for a nondissipative interaction.
TRUE
negative gradient of potential energy is equal to non dissipative type of forces

Answer:
Malthus objection was that the pressure of increasing population on the food supply would destroy perfection and there would be misery in the world.
Malthus was severely criticized for his pessimistic views,which led him to travel to the continent of europe to gather data in support of his thesis
