Answer:
Velocity- v=10m/s south Speed- v=10m/s
Explanation:
the salar measurement of how fast an object is moving.
Velocity- v=10m/s south :
The vector rate of change of position.
Speed- v=10 m/s : the salar measurement of how fast an object is moving.
Its called the Phase Transition. Im assuming your asking what is it called when matter transitions between solid liquid and gas.

Answer:
∆E = 4.16J
Change in internal energy of the tie and spike is 4.16J
Explanation:
Given;
Mass of spike m = 0.77kg
Initial Speed of spike v = 3.5m/s
Efficiency = 88.3%
Kinetic energy of spike can be calculated as;
K.E = 1/2 × mv^2
Substituting the values;
K.E = 1/2 × 0.77 × 3.5^2
K.E = 4.71625J
Change in internal energy of the tie and spike;
∆E = 88.3% of K.E
∆E = 0.883 × 4.71625J
∆E = 4.16J
Change in internal energy of the tie and spike is 4.16J
B is the answer
