Answer:
So Trent is moving at 75mph 53.13° Southwest of Susan.
Explanation:
Given
Susan moves south direction at 60mph
Trent moves east direction at 45 mph
Trent relative velocity can be obtained using the polar coordinate
So converting these cartessian system to polar coordinate using the formula
R=✓(y^2+x^2)
and it's angle by arctan(y/x)
R=√(60^2+45^2)=√(5625)=75mph
Direction=arctan (-60/45)=-53.13°
Assume north direction is positive axis and south Negative direction
So Trent is moving at 75mph 53.13° Southwest of Susan.
Answer:
True
Explanation:
Because the proportion of fast alcohol- metabolizing flies will increase
Answer:
Following are the option are the correct option to the given question
- Plane landing on an aircraft carrier.
-
Rain sticking to a window.
-
Two train cars coupling together.
Explanation:
In the inelastic collisions is the kinetic energy is not preserved because of the some internal friction.In the elastic collision there is shortage of the kinetic capacity.
- When the airplane is landing it has always been in contact with the surface to relieve the inelastic collision condition.
- When then rain falls the clinging to the door once it intersect with as well so it is satisfied the condition of inelastic collision.
- When the two train or cars collide there is loss of kinetic energy so it is satisfied the condition of inelastic collision.
- All the other option is not the example of inelastic collision that's why they are incorrect option.
Adiabatic rate is used to describe the change in temperature as a result of the rising or the sinking of an air parcel.
Knowing that the dry adiabatic rate of change for unsaturated air is 10°C/1000 m means that the temperature of the unsaturated air parcel would increase (get warmer) as the air parcel sinks and will decrease (get cooler) as the air parcel rises.
Hope this helps :)
