Answer:
D.Conduction, because the metal wire was in direct contact with water in both containers
Answer:
111.8 m
Explanation:
Displacement is the change in position of an object. The SI unit of displacement is the meters. The displacement of an object can be calculated by determining the shortest distance from the starting point to the end point.
Since earl travels 50 m east and then 100 m north, let x represent the displacement. Therefore x is the shortest distance from starting to end. Earl movement forms a right angled triangle with x as the hypotenuse. Hence:
x² = 50² + 100²
x² = 12500
x = 111.8 m
The time taken for the bus to travel 95.1 m is 2.8 s
<h3>How to determine the final velocity</h3>
- Initial velocity (u) = 26.8 m/s
- Acceleration (a) = 4.73 m/s²
- distance (s) = 95.1 m
- Final velocity (v) = ?
v² = u² + 2as
v² = 26.8² + (2 × 4.73 × 95.1)
v² = 1617.886
Take the square root of both sides
v² = √1617.886
v = 40.2 m/s
<h3>How to determine the time</h3>
- Initial velocity (u) = 26.8 m/s
- Acceleration (a) = 4.73 m/s²
- Final velocity (v) = 40.2 m/s
- Time (t) = ?
v = u + at
40.2 = 26.8 + (4.73 × t)
Collect like terms
4.73 × t = 40.2 - 26.8
4.73 × t = 13.4
Divide both side by 4.73
t = 13.4 / 4.73
t = 2.8 s

Answer:
acceleration, a = 
distance, d = 80 m
Given:
Initial velocity of object, v = 20 m/s
Final velocity of object, v' = 60 m/s
Time interval, 
Solution:
(a) Acceleration is the rate at which velocity changes and constant acceleration is when the velocity changes by equal amount in equal intervals of time.
Thus
acceleration, a = 
a = 
(b) Now, the distance covered is given by:
