Answer:
The atoms of the system with higher temperature will gain the heat energy and the vibration of these atoms will increase. The atoms or molecules on the system with lower temperature have lower temperature and are not vibrating. ... So, we can say that heat always flows from higher temperature to a lower temperature.
Answer:
F=507.7N
Explanation:
According to Newton's second law:
in this case, the football players need to drag the coach at a constant velocity, thus means with no acceleration, so:
there are 20 degrees between the two ropes that means each player exerts a force 10 degrees from the zero reference.
I'm not sure what your question is. But, the half life is the amount of time required for half the material to decay. For U238 this is 4.5 billion years, whilst for Fr-223 (Francium) its about 22 minutes. To calculate the time for something to decay you need to use the equation:
Mass (after time t) = Mass (initial) * (0.5)^(time/half life)
Hope this helps
Answer:
The answer is 8.44*10^9 Newton
Explanation:
The equation for universal gravitation is:
Where:
G= 6.674×10^−11 N · (m/kg)^2
M(earth)=5.972 × 10^24 kg
M(asteroid)=5.0×10^13 kg
r=1.537*10^9 m (Calculated from average distance between moon and earth)
The force will be:
8.44*10^9 Newton
