Answer:
d. 0.043 g/s
Explanation:
Formula for rate of conduction of heat through a bar per unit time is as
follows
Q = k A ( t₁ - t₂ ) / L
A is cross sectional area and L is length of rod ,( t₁ - t₂ ) is temperature
difference . Q is heat conducted per unit time
Putting the values in the equation
Q = (427 x 1 x 10⁻⁴ x 100 )/ 30 x 10⁻²
= 14.23 J/s
mass of ice melted per second
= Q / Latent heat of ice
= 14.23 / 334000
= 0.043 g/s
Answer:
C = A - B
Explanation:
The addition of vectors takes into account the magnitude of each vector and its direction, so when adding two vectors, the result depends on the direction of the vectors.
* If the vectors have the same direction the result is maximum
C = A + A
* if the vectors have 90 between them, the magnitude of the result is given by the Pythagorean Theorem
C = √(A² + B²)
* if the vectors have 180º between them the result is minimal
C = A - B
We can also perform this sum graphically, where the resulting vector goes from the origin of the first vector to the tip of the last one, it can clearly be seen that when the vectors are antiparallel (180º angle) the magnitude is minimal

Answer:
The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body's biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of more ATP must start quickly.

The combined momentum of the passengers is 5000 kgm/s.
<h3>Combined momentum of the passenger</h3>
The combined momentum of the passengers is calculated as follows;
P = mv1 + mv2
where;
- m is mass of the passengers
- v1 is velocity of the first passenger
- v2 is velocity of the second passenger
P = m(v1 + v2)
P = 5000(-1 + 2)
P = 5000 kgm/s
Thus, the combined momentum of the passengers is 5000 kgm/s.
