Answer:
Chidera is the stronger individual pushing the box with a net force of 5N to the left.
Explanation:
Chidera is using more force meaning they are stronger and the net force is 5N because when you plug in the equation
F1 = 30 + F2 = -25 = 5N
you get 5N
Answer:
5.7s
Explanation:
it is stationary when v = 0 so use the equations of motion to find t. Please see photo attached
Answer:
lacceleration is given by
a=F/m
With force acting on the object remained constant ,the acceleration is inversly proportional to mass of the object i.e with increase in mass =>acceleration decreases and with decrease in mass => acceleration increases.
a)
acceleration decreases
b)
acceleration increase
Answer:
When the thermometer is warmed, the liquid expands by more than the volume of the hollow space in which it is confined, and so some of it must move from the bulb into the capillary tube. It should be conduction and then convection/advection, not radiation. Radiation is usually the slowest heat transfer.
