what is the displacement of a cyclist who travels 1 mile north 1 mile east then finally 1 mile south
Answers
The displacement of a cyclist who travels 1 mile north 1 mile east then finally 1 mile south will be 1 mile in the east direction.
What is the displacement?
A displacement is a vector in engineering and mechanics that has a length equal to the shortest route between a point P's initial and final positions.
The displacement is the vector quantity that depends on the magnitude as well as direction. And follows the law of vector addition.
The cyclist who travels 1 mile north 1 mile east then finally 1 mile south. Then the diagram is drawn below.
From the graph, the displacement is given as,
Displacement = 1 - 0
Displacement = 1 mile
The displacement of a cyclist who travels 1 mile north 1 mile east then finally 1 mile south will be 1 mile in the east direction.

Answer:
950-kg subcompact car be moving to have the same kinetic energy of truck at 116.08 km/hr
Explanation:
Kinetic energy of body with mass m and moving at velocity v is given by
KE of truck
KE of subcompact car
Equating
So 950-kg subcompact car be moving to have the same kinetic energy of truck at 116.08 km/hr
Final answer:
To have the same amount of kinetic energy as a 3.2x10^4kg truck moving at 20km/h, a 950-kg subcompact car would need to be moving at an approximate speed of 224 m/s.
Explanation:
The problem requires us to calculate the speed that a 950-kg car must achieve to have the same kinetic energy as a 3.2×104-kg truck moving at 20 km/h. The kinetic energy of an object is represented by the equation K = 0.5mv² where m signifies mass and v speed.
The truck's kinetic energy can be calculated using this formula: Ktruck=0.5(3.2×104kg)(20 km/hr * 1000 m/km / 3600 s/hr)² = 1.96 x 107 J.
For the car to have the same kinetic energy, we set up the following equation and solve for v: 1.96 x 107 J = 0.5(950 kg)v², yielded v = 224 m/s.
Thus, the subcompact car needs to move at a speed of 224 m/s to have the identical kinetic energy as the truck moving at 20 km/h.

B) one Neutron
C) six Electrons
D) These masses are too tiny to measure
Answers
One proton or one neutron have very close to the same mass.
Their mass is about the same as the mass of 1,840 electrons !
So six electrons have roughly the same mass as 0.0033 of one
proton or one neutron.
Yes, these masses are very tiny. None of them was ever measured
until the 20th Century. But all of them have now been measured,
very precisely and accurately. This is very impressive, and should
give us a lot of admiration for scientists of the past hundred years.
It would be very interesting to look around online and find out
how they did it.
