Answer:
Q = 590,940 J
Explanation:
Given:
Specific heat (c) = 1.75 J/(g⋅°C)
Mass(m) = 2.01 kg = 2,010
Change in temperature (ΔT) = 191 - 23 = 168°C
Find:
Heat required (Q)
Computation:
Q = mcΔT
Q = (2,010)(1.75)(168)
Q = 590,940 J
Q = 590.94 kJ
Answer:
The object will accelerate in the upward direction.
Explanation:
To know the direction in which the object will accelerate, we shall determine the net force acting on the object. This can be obtained as follow:
Upward force (Fᵤ) = 300 N
Downward force (Fₔ) = 200 N
Net force (Fₙ) =?
Fₙ = Fᵤ – Fₔ
Fₙ = 300 – 200
Fₙ = 100 N upward
Thus, the net force acting on the object is 100 N in the upward direction. This implies that the object will accelerate in the upward direction because the net force acting on the object is in the upward direction.
Answer:
Downwards into the plane
Explanation:
Solution:-
- This is a conceptual application of hand rule. We will place our palm fingers open vertical to a plane surface. Then curl our fingers in and naturally point the thumb.
- The direction of curl of fingers denotes the direction of of current flow in the coil. Which in our case is "clockwise direction". We will orient/invert our right hand palm in such a way that we curl our fingers in clockwise fashion. Then stick the thumb out to give us the direction of magnetic field or North pole end. In our case the the thumb points downwards into the plane denoting that the magnetic field within the loop is also acting downwards into the plane.
- The bar magnet would be placed in such a way that North pole is pointing downward into the plane in the direction of magnetic field and end up at south pole pointing up out of the plane.
