Answer:
Explanation:
m1 = 3.77 kg (0, 0 )
m2 = 6.7106 kg ( 5.72 cm, 11.44 cm)
m3 = 2.46181 kg (16.7024 cm, 0 cm )
Let x and y be the coordinates of centre of mass.
x = 6.1428 cm
y = 5.9316 cm
The Law of Conservation of Matter states that the mass of the reactants equals the mass of the products.
Thus, your answer is A
A as the radiant from the object heats it up its kinda like thermal heat in a way
The power transferred by the motor is equal to the product between the current and the voltage:
However, the power used by the winch system is less than this value. In fact, the work done is equal to the weight of the load times the distance through which it has been lifted:
And the power used by the system is the work done divided by the time taken:
Therefore, the efficiency of the system is given by the ratio between the useful power and the power in input:
