Hi, if you draw a diagram of what is actually happening you will be able to understand what is happening much easier. Also displacement means distance from the starting point not the distance traveled if you didn't know already. so |dw:1318897040544:dw| if you follow this diagram you can see how the child has walked, you can then make a triangle and work the displacement which in the case is the root of the sum of the two other sides. This is just Pythagoras a^2+b^2=c^2 2
Its is solute. The dissolved substance. In salt water, salt is the solute and water is the solvent.
Momentum is mass times velocity of the object
p = m • v
p = (7700 kg)(14 m/s)
p = 107809 kg m/s
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
