If an object<span> is slowing down, then its </span>acceleration<span> is in the opposite direction of its motion. ... In Example A, the </span>object<span> is moving in the positive direction (i.e., has a positive </span>velocity<span>) and is speeding up. When an </span>object<span> is speeding up, the </span>acceleration<span> is in the same direction as the </span>velocity<span>.</span>
Answer: Net Force, also is referred to as Resultant Force
Answer:
741 J/kg°C
Explanation:
Given that
Initial temperature of glass, T(g) = 72° C
Specific heat capacity of glass, c(g) = 840 J/kg°C
Temperature of liquid, T(l)= 40° C
Final temperature, T(2) = 57° C
Specific heat capacity of the liquid, c(l) = ?
Using the relation
Heat gained by the liquid = Heat lost by the glass
m(l).C(l).ΔT(l) = m(g).C(g).ΔT(g)
Since their mass are the same, then
C(l)ΔT(l) = C(g)ΔT(g)
C(l) = C(g)ΔT(g) / ΔT(l)
C(l) = 840 * (72 - 57) / (57 - 40)
C(l) = 12600 / 17
C(l) = 741 J/kg°C
The answer is D. hope this helps.
Answer:
Explanation:
According to the Biot–Savart law, the magnitude of a magnetic field created by the current in a long straight wire, is defined as:
Where 
is the permeability of free space, I is the current circulating on the wire and R is the distance from the point where B is measured.
Solving for I:
