A 50 kg box is placed on a table. A force of 50N upwards is exerted on the box. What would you observe happening to the box? A. The box would remain stationary on the table

B. The box would lift off the table for a short time and then fall down again

C. The box would move upwards

D. The box Would move downwards

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
