Explanation:
c. if the vector is oriented at 0° from the X -axis.
A. hot is the correct answer.
Hope it helps!
The answer is: [C]: "4" .
___________________________________________________
Note: To balance this equation, the coefficient, "4", should be placed in front of the PCl₃ ; and the coefficient, "6", should be placed in front of the Cl₂ .

Answer:
Explanation:
<u>Kinematics equation for first Object:</u>

but:
The initial velocity is zero

it reach the water at in instant, t1, y(t)=0:


<u>Kinematics equation for the second Object:</u>
The initial velocity is zero

but:

it reach the water at in instant, t2, y(t)=0. If the second object is thrown 1s later, t2=t1-1=1.02s

The velocity is negative, because the object is thrown downwards.
